Viewpoint

The quest for operating efficiency drives innovation and technology.

T

he message from governments, bankers and ship operators seems to be very similar this year to last, 2012 will be another tough year. Banks have been cutting their shipping exposure and financing has become more difficult as lending has tightened. The European Union continues to pursue tighter financial integration, and in the U.S. real growth is proving elusive. With China slowing, global growth forecasts for 2012 have now reduced to around 3.5 per cent. How things will eventually unfold – and the knock-on effect this will have – is not clear. Continuing volatility, at least in the near term, is likely to be the norm and the eventual outcome is likely to have longer term implications for shipping in general. While challenges abound across the industry, the higher value sectors are proving resilient. In the highly specialised offshore oil and gas sector, further investment in deep water exploration and production looks particularly robust. We have recently secured orders to provide thrusters and engines for drillships in addition to UT-Design Platform Supply Vessels and Anchor Handlers. The shift to low sulphur fuels and the focus on sustainable shipping has seen the steady uptake in LNG as

the fuel of choice for a growing number of newbuilds scheduled for delivery by the 2015 ECA regulation deadline. Our gas engines have been selected to power a number of these vessels, including the world’s first all-gas tugs. We recently secured orders for the NVC 405 general cargo carrier variant of our award winning Environship concept. This innovative design delivers greenhouse gas emission reductions of more than 40 per cent compared to similar vessels. The quest to reduce operating costs and the environmental impact of vessels has been at the centre of our thinking for some time, and this drives our innovation and technology investment programmes to meet the challenges our customers face. In the naval sector, we have received orders for power and propulsion systems for two more Littoral Combat Ships for the US Navy. Twin MT30s power these vessels, and benefit from over 45 million hours of airline operating experience. Rolls-Royce and Daimler have also joined forces to create a new marine and industrial engine joint venture through the acquisition of Tognum, maker of MTU high speed diesel engines for use at sea and on land. The engines and technology portfolios are highly complementary to our Bergen medium speed engines. As marine systems and equipment suppliers, the goal of Rolls-Royce is to provide ship builders and ship operators in the merchant, offshore and naval sectors with cost effective, efficient and environmentally compliant systems. A gas engine is a good start in reducing emissions, but it is the effective integration of other energy saving designs and technologies – for which we have a strong track record and remains our continuing goal – that makes the real difference. I hope you enjoy reading more about how this is being delivered through the articles in this latest edition of In-depth. TONY WOOD President - Marine

waterjets for new Indian Coast Guard fast patrol boats Rolls-Royce has secured a contract from India’s Cochin Shipyard to supply waterjets for 20 new fast patrol vessels for the Indian Coast Guard. A total of 60 Kamewa 71S3np waterjets (three per vessel), and associated equipment including a joystick control system, which will enhance the manoeuvring capabilities of the vessels, are to be supplied. The new Kamewa S3 design offers ffers higher speeds, improved ff acceleration and increased efficiency. Power for each of the 48m long vessels will be provided by three MTU 16V 4000 M90 engines, each rated at 3,648kW. The new vessels will be capable of speeds up to 33 knots. Rolls-Royce has been a supplier to the Indian Coast Guard for over 20 years with a large number of waterjets already in service, as well as CP propellers and stabilisers on other vessels in the fleet. The first

of three UT 517 pollution control vessels, Samudra Prahari, entered service in 2010. Construction of the new ships is part of an expansion of the Indian Coast Guard. When they enter service they will operate in Indian coastal waters and around island territories. Their roles will include coastal patrolling, anti-smuggling missions, fisheries protection, as well as search and rescue duties.

A milestone in green tug development has been reached with Buksér og Berging ordering Rolls-Royce gas propulsion systems for two powerful LNG-fuelled escort tugs to operate at the Kårstø gas terminal near Haugesund in Norway. The tugs will work for the state-owned oil company Statoil and the process plant operator Gassco on delivery in the third quarter of 2013. They are 35m long stern drive azimuth thruster tugs with a broad 15.4m beam and a bollard pull of about 65 tonnes. The design was developed by Buksér og Berging together with Marin Design. “This is a breakthrough for our Bergen gas engines in the tug market, and for our new US35 thrusters in escort tugs,” says Robert

Løseth, Senior VP - Merchant, Propulsion Systems and Engines. “It confirms that our unique engine performance characteristics in terms of response time, fuel consumption and low methane slip are important to our customers.” Two 1,705kW Bergen C26:33 6 cyl in-line gas engines will provide the power. They will drive two US35 azimuth thrusters of the latest design through a mechanical transmission. Rolls-Royce will also provide its ACON control system and monitoring for the gas system, together with propulsion system engineering, and the AGA Cryo single LNG tank plus gas supply based on two coldboxes. The system is designed for weekly bunkering intervals and bunkering time is

03

estimated to be 45 minutes. Vetle Sverdrup, Commercial Director at Buksér og Berging AS, said, “We wanted to base the design of the new tugs on the spark ignition lean burn engine concept, and the ability to accommodate direct drive in addition to a low emission profile. The propulsion system on high performance escort tugs needs to accommodate rapid load pickup over the entire load range. Due to these factors, we chose to work closely with Rolls-Royce on this project.” The tugs are being built in Turkey by Sanmar Marine. For more details, go to page 6.

Seismic streamer systems for advanced COSL vessel The seismic survey vessel, named HYSY 720, has entered service with China Oilfield Services Limited (COSL) and is now operating in the South China Sea. The vessel is equipped with a Rolls-Royce streamer handling system capable of towing 12 streamers, each 8,000m long, to perform high-density seismic data collection. It is the first and most advanced deepwater seismic survey vessel built in China so far and is 108.3m long with a 24m beam, a draught of 9.6m and has an

endurance of 75 days. To increase operating efficiency, the vessel is designed for a speed of 16 knots and a towing speed of five knots and has a dieselelectric propulsion system. This will significantly reduce mobilisation and demobilisation times, and also contributes to improving the

comfort of the working and living environment for the crew. The model ST-327L CD vessel is equipped with a new generation of seismic collection system, integrated navigation system and lateral control system. Up to 75 people can be accommodated onboard.

more Littoral Combat Ships

The contract to supply power and propulsion systems for the two latest vessels in the U.S. Navy’s Littoral Combat Ship (LCS) programme was recently secured by Rolls-Royce. Designed to operate in combat zones close to the shore, each LCS will be equipped with two Rolls-Royce MT30 gas turbines driving four large Kamewa waterjets, enabling the vessels to reach speeds well in excess of 40 knots. This latest order is for ships named Little Rock and Sioux City, and follows previous orders for the Milwaukee and the Detroit, which are both under construction. Rolls-Royce already powers two Lockheed Martin Littoral Combat Ships, the USS Freedom, first deployed two years ago, and the Fort Worth, which has now completed its U.S. Navy acceptance trials. Andrew Marsh, President - Naval said, “We have worked closely with Lockheed Martin, the U.S. Navy and other partners during the LCS programme, using our extensive experience to further develop these highly advanced ships. The combination of the MT30 gas turbine and our latest waterjet technology will ensure these ships are at the cutting edge of global naval capability.” The MT30 is derived from Rolls-Royce aero engine technology and builds on over 45 million hours of operating experience.  At 36 megawatts, it is the world’s most powerful marine gas turbine and has the highest power density in its class. The waterjets are among the largest produced by Rolls-Royce. A range of other Rolls-Royce equipment is specified in the Lockheed Martin design, including shaftlines, bearings and propulsion system software.

New service centre in Hong Kong The Rolls-Royce service presence in Hong Kong has been expanded recently with the opening of a new and enlarged service centre on Tsing Yi Island. It provides specialist support and engineering services to the Greater China region and forms an important component of the Rolls-Royce service network that covers the entire east coast of China, with existing facilities in Dalian, Guangzhou and Shanghai. “With a growing customer base in Greater China, coupled with an increasing number of customer operations within the region, we

have relocated and expanded our facilities to ensure we can deliver our services close to where our customers operate,” says P. T. Tong, Branch Manager. “Service engineers based here are on hand to provide technical support wherever and whenever required.” The new facility will provide support for a variety of vessels, including a large number of fast ferries that are in service between Hong Kong, Macau and the Pearl Delta. A large number have Rolls-Royce propulsion systems installed. It provides direct waterfront access to major transport channels

and is capable of undertaking major repair, overhauls and upgrades for popular Rolls-Royce products that include waterjets, tunnel thrusters, azimuth thrusters and deck machinery. Sales support in Hong Kong has also moved to the new facility.

Four deepwater anchor handling vessels to get advanced deck machinery Rolls-Royce has secured a contract from Swire Pacific Offshore to supply advanced anchor handling systems for four offshore vessels, currently under construction in Singapore. The systems are developed for the safer handling of large anchors on deck, such as the torpedo anchors used in the deepwater oil and gas fields off the coast of Brazil.

Arne Tande, Senior VP - Offshore Deck Machinery, said, “Rolls-Royce supplies world-leading marine technology that enables our customers to operate safely in challenging conditions, such as the deepwater oil and gas fields. We are delighted that Swire Pacific Offshore has again selected our safety-critical technology, which demonstrates that our focus on research and development and advancements in the technical capabilities of our products continues to position Rolls-Royce as the market leader for specialist handling equipment in the offshore industry.”

Asian orders for popular deepwater UT designs The rapid expansion of Asia into the offshore industry looks set to continue, with shipyards and operators selecting Rolls-Royce designs for deeper waters. Singapore-based PaxOcean Engineering is building two PSVs to the Rolls-Royce UT 755 CD design, at its shipyard in Zhuhai, China. The vessels combine a proven ship design

with a range of Rolls-Royce onboard technologies that include diesel-electric propulsion and deck machinery. They are also equipped for firefighting and oil recovery. The UT 755 CD has a deck cargo area of 670m2 and an overall length of 78.7m with a 16m beam. Planned delivery is the first half of next year. In China four UT 771 CDL vessels will be built by the COSCO (Guangdong) Shipyard Co. Ltd. These complex vessels are flexible and highly efficient, featuring a fully integrated systems package comprising diesel electric

propulsion system, deck machinery, bulk handling equipment and automation and control systems. The vessels will also be able to undertake firefighting duties. They will be equipped for transporting pipes, equipment and cargo to and from pipelaying barges, oil drilling and production platforms. Delivery is scheduled for 2014 and the contract includes options to build an additional six vessels of the same design. Korean shipbuilder Hyundai Mipo Dockyard Co. Ltd is to build four UT 776 CD vessels. Hyundai’s President and CEO W G Choe said, “We are extremely pleased to enter into this deepwater segment by building vessels of a world-leading design from Rolls-Royce.” The 4,400t, 90m long UT 776 CD design incorporates a range of Rolls-Royce systems like diesel-electric propulsion. They will be built at Hyundai’s Ulsan shipyard for delivery in 2013 and 2014. The contract includes options for a further two vessels.

roviding propulsion systems for tugs comprising Bergen diesel engines driving azimuth thrusters of various specifications, is something Rolls-Royce has been successfully doing for over 25 years. The rapid response to load and excellent low load fuel consumption of the Bergen range of gas engines makes them ideally suited to tug applications. This, coupled with the extensive experience of Rolls-Royce in providing gas engines for marine propulsion, has seen designs for LNG-fuelled tug propulsion being developed for several years. The high power density of the recently introduced Bergen C-series gas engines is also an important factor. The particular attraction of Rolls-Royce Bergen C-series gas engines to power tugs is low levels of emissions. These include the greenhouse gas CO2 which has a global impact, and because methane slip is very low in this engine type, the total GHG emission reduction is not seriously compromised by unburnt methane in the exhaust. NOx emissions are reduced by around 90 per cent and SOx is negligible. Also important in tugs working in ports and approaches, which are often close to residential areas of high population density, is the absence of soot and smoke particulates. Of growing concern are emissions to water, and the likelihood of oil spills is much reduced when LNG is the fuel. Bergen gas engines have a high thermal efficiency. SFC, NOx and CO2 emissions are actually lower at low engine loads, the reverse of most diesel engines. The C-series gas engines are also approved for both direct

mechanical drive or as gensets and can accept rapid changes in load. They can therefore be used in a variety of propulsion solutions, depending on the operating profile of the tug. A study of ship assist tug operations shows that a tug has a varied working profile. Long-term operational studies demonstrate that harbour tugs will typically only spend 29 per cent connected to a ship, actually carrying out its assistance duties, 33 per cent of total operation time in transit, sailing from and towards a job, while the remaining 38 per cent is spent on standby and loitering. Throughout a day or week, a tug’s power requirements can vary tremendously. Diesel engines normally have a much higher level of specific emissions and fuel consumption at low loads, compared with the most efficient operation at high loads in terms of emissions and fuel burnt per unit of power output. A characteristic that has resulted in the recent move to hybrid tugs by some operators. It is here that Rolls-Royce lean burn gas engines score. Rolls-Royce has evaluated a number of LNG-fuelled propulsion systems for harbour tugs and the first are now under contract (see page 2). The system selected produces over 65 tonnes bollard pull and uses a stern drive azimuth thruster layout based on two US 35 CP thrusters with controllable pitch propellers. They are directly driven by two Bergen C26:33L6PG gas engines, each delivering 1,705kW and running at 1,000rpm. Aquapilot controls and ACON automation are part of the package.

A vertical C-type gas tank of 78m3 capacity and two separate cold boxes are installed under the foredeck and provide sufficient capacity for 150 hours running at 50 per cent load. Refuelling is a simple operation and is required once a week from either a shore-based tank, road tanker or transport storage unit. Fuel transfer time is just 45 minutes, provided a 100m3/hr 33/hr system is used. Although the initial capital costs are higher for gas propulsion due to the cost of the fuel system, this can be offset within a relatively short time by significantly lower annual operating costs. You also have a very environmentally friendly vessel that satisfies forthcoming legislation, with the emissions reduction advantage there from day one. Ship construction data is used to calculate the vessel environmental ship index (ESI). This is a score based on the vessels environmental credentials. It is expected that in the future, this, or a similar scoring system will be used to tax vessels entering port. The score does give a good indication of how much more environmentally friendly LNG as a fuel is, compared to MGO. These analyses are based on long-term experience with tug propulsion. Rolls-Royce supplies engines, thrusters and winches for tugs all over the world and the US series azimuth thrusters are particularly popular due to their good performance and robustness. US 205 FP thrusters already propel environmentally friendly tugs and have been selected for the second of the Foss hybrid tugs, following the successful operation of the first of the type, Carolyn Dorothy Dorothy, at Long Beach and Los Angeles over the past two years.

Rolls-Royce and Bestway unveil new energy-efficient ship designs Combining proven European ship design and systems experience with Chinese capabilities in ship building, Rolls-Royce is delivering a range of new commercial ship designs.

T

he global shipping industry is now firmly committed to using vessel designs and systems that will cut greenhouse gas emissions. China is also entering a green era, with national policy supporting energy efficiency and environmental protection, with the target of cutting CO2 emissions per unit GDP by 40-45 per cent by 2020. To meet the evolving low emissions requirements of the global, intra-regional and inland shipping trade, particularly in Asia, Rolls-Royce and Bestway formed a Joint Project Team (JPT) in Shanghai at the start of 2011. The first of the new designs have now emerged. They range from 2,500 to 100,000 deadweight tonnes (dwt), including the 4100 Series roro carriers (from below 9,000 – 11,000dwt and above), the

4400 Series container carriers (up to 2,000teu), the 4600 Series general cargo carriers (up to 40,000dwt), the 6400 Series LNG carriers (up to 40,000m3) and the 4800 Series bulk carriers (up to 100,000dwt). All are designed to comply with and exceed future emissions targets. ”As more international emissions controls are progressively introduced, the marine industry is collaborating to ensure that designers, equipment manufacturers, yards and owners work together to create highly efficient vessels that improve operating costs while reducing harmful environmental impacts,” says

Arne Magne Vik, JPT Technical Director. ”Through our collaboration with Bestway, we are well placed to lead this charge.” The designs benefit from the combined design and systems expertise of both companies in producing highly efficient vessels tailored specifically for the future merchant shipping market, in which low emissions and reduced operating costs are key drivers. This includes the application of Liquified Natural Gas (LNG)fuelled propulsion, which is gaining acceptance globally as a marine fuel, and where Rolls-Royce has accumulated significant experience with 23 gas-powered vessels now in service or on order. With the exception of the general cargo/bulk designs, which have diesel-only systems at the moment, all designs have the propulsion options of either conventional diesel/hybrid or gas. Those designs featuring Rolls-Royce Bergen gas engines already meet IMO Tier III requirements for nitrogen oxide (NOx), sulphur oxide (SOx) and carbon dioxide (CO2) emissions, which come into force in 2016. With the Energy Efficiency Design Index (EEDI) being mandated from 2013, each design has been given an EEDI rating calculated using MEPC 1/Circ 681. However, they are subject to change, as the formulae have not been fully clarified for some vessel types. Roro vessels in the JD4100 model range feature a low drag hull form and sea-friendly bow with twin Promas integrated propellers and rudders. Three are based on the same 150m hull design, have a deadweight of 9,000dwt and carry

200teu on the upper deck with 1,800 lane-metres, but have different fferent stern ramp arrangements. Diesel or gas ff propulsion can be specified. Lane-metre capacity of the gas-powered JD4103GF is reduced by 50m, as some cargo space is lost to the gas tank. The 166.6m long JD4104GF, with a deadweight of 11,000dwt, 21,000 lane-metres and capacity for more than 250teu, is currently the largest in the family. It has the same propulsion system as its smaller sister, which comprises of twin Bergen B32:40L8PG main engines, rated at 3,220kW, and a Bergen C26:33L6AG 2,000kW auxiliary generator, hence the slightly slower service-speed of 15.6 knots. Range for the gas-powered ships is 6,000nm, with 6,500nm for conventional diesel power. EEDI ratings range from 19.4 to 15.9, although they do not yet apply to roro vessels. The JD4400 series container vessel family so far comprises two designs able to carry 2,250teu and 2,194teu respectively. Both are 198.5m long with a deadweight of 30,000dwt. There is an extra cost for the LNG system and a reduction in cargo handling of

56teu to make room for the gas tank. However, the extra capital cost and the theoretical loss of earnings are more than offset ffset by the fuel economies ff and lower emissions of the LNG-fuelled variant, which has an EEDI of 12.2. It is powered by a single Bergen B35:40V16PG, driving a single Promas system with CPP, supplemented by three Bergen C26:33L9AG generator sets, powering through a power-take-in (PTI). The diesel-powered JD4401 drives a FP Promas system and has a 1 knot faster service speed of 18.5 knots with an EEDI of 13. Adopting a similar hull design and propulsion arrangements are the JD4601, a 37,000dwt handysize bulker, and the JD4801, a 37,000dwt general cargo carrier. Both vessels are 180m long, with a beam of 29.8m and an EEDI of 4.4. Propulsion power is provided by a 6,250kW diesel, driving a FP Promas system for a service speed of 14 knots. The final designs are small LNG carriers with capacities from 5,000 to 40,000m3, ideal for the anticipated demand in smaller vessels to supply LNG bunkering points as the world’s LNG infrastructure develops. All have an EEDI of 23.1, a range of 1,500nm and a service speed of 13 knots. Smallest is the 5,000m3 JD6401, with a length of 99.9m and 18.4m beam. Main engine

is a Bergen C26:33L8PG, rated at 2,160kW, which drive a single Promas system, and a Bergen C26:33L6AG genset. Both engines are able to run on boil-off ff gas (BOG) or LNG from twin 80m3 storage tanks. A hybrid shaft generator provides the electrical power, which can be used to increase propulsion power or for redundant propulsion. The larger JD6405 with 10,000m3 capacity can be specified with either gas or dual fuel propulsion. It is a shallow draft design well-suited for rivers and coastal waters and has a length of 124.9m and a 22.4m beam with 4.5m draught. Propulsion power is provided by twin 1,620kW Bergen C26:33L6PG engines driving Promas systems and running on LNG stored in two 120m3 tanks. The dual-fuel version incorporates two 425kW diesel gensets that can also provide extra power and emergency propulsion through a hybrid shaft generator system. [AR]

hip and systems design is an area where Rolls-Royce continues to invest heavily in research and development, to ensure that the company’s designs are the optimum for the customer’s needs and can cope with real operating conditions. A combination of CFD (computational fluid dynamics) and tank testing is used. Promising designs can then be verified by tank testing and compared with operational feedback from over 800 Rolls-Royce designed offshore and merchant vessels operating globally. Because of its extensive product range, Rolls-Royce has the ability to integrate complex ship systems that are engineered to work efficiently together. As an integrator and a designer, it aims to get the best products together as an efficient system and design the optimum ship around them. The design process normally starts by sitting down with ship owners to gather as much data as possible on what they want their vessels to do. Details such as operating routes, anticipated weather conditions, turnaround times in port and the type of cargo all have a significant impact on the design. A detailed picture of the operating profile is built up long before a ship gets to the drawing board. With the introduction of new IMO emissions regulations in 2016, it is also 1

very important to plan ahead and consider the legislative landscape and any other requirements that may be in place when the vessels enter service. The result for the customer is that the performance of a new design can be predicted early in contract negotiations, giving confidence that the actual ship will behave as calculated and the full benefits of innovation realised.

Integrated processes Development of a hull form with the required performance for the customer’s operation goes hand in hand with structural strength and steel work calculations. Once a ship design has been agreed on with the owner, Rolls-Royce works closely with the shipyard and the owner to develop detailed specifications and working drawings. As shipyards across the world build Rolls-Royce designed vessels, there is a three-way relationship between the yard, the ship owner and the designer. For merchant vessels, a team in Croatia specialises in producing the detailed production drawings of the ship and the installed equipment. Using powerful software, the exact order of build can be specified, as can input for the computer programmes that will cut and weld the steel. Over the last year, there have been a number of examples.

NVC 405 – the first of a new generation Last year, Rolls-Royce unveiled its new Environship concept general cargo vessel and secured its first orders from Norwegian transport group Norlines. The 112m long and 5,000dwt design combines the best available gas power and propulsion technology into an innovative hull design to provide numerous environmental benefits, including the virtual elimination of SOx and a reduction of CO2 emissions by more than 40 per cent compared to similar vessels. The hull incorporates improvements in hydrodynamics and wave piecing technology (patent pending) that enables the ship to cut through rather than ride over waves for improved performance in a seaway, enabling

operators to remain on schedule without needing to burn additional fuel to make up lost time. Powered by a single Bergen B35:40 V12 gas engine developing 3,930kW, two of the vessels are now being built at the Tsuji Heavy Industries shipyard in Jiangsu, China. The vessels will enter into service progressively from October 2013, operating along the West Coast of Norway.

NVC 604 – Bunker tankers Three NVC 604 bunker tankers have been designed for Brazilian operator Navegação São Miguel Ltda (NSM) to build at their own yard in Niteroi, Brazil. The vessels have Rolls-Royce systems and equipment and are to be delivered by the end of 2014. Rolls-Royce has had a fruitful cooperation with NSM for almost two years developing these vessels, which are optimised to meet very specific requirements, with a high focus on large cargo tank volume, high deadweight and good course keeping in shallow areas. The vessels will have DNV class, fly the Brazilian flag and are designed for coastal trade in Brazil. The cargo will be heavy fuel oil (HFO) and marine gas oil (MGO) to a total deadweight of about 4,350t at the design draught of 4.5m. Service speed will be approximately 10 knots. Overall length is 90.2m with a beam of 18.2m. NSM began to provide bunkering operations in 1964 in Guanabara Bay

(Rio de Janeiro) to supply the then incipient Petrobras oil giant. The company is now responsible for more than 9,000 fuel loading and supply operations to ships along the entire Brazilian coastline and the three new tankers will join the owner’s fleet of about 40 specialised vessels.

NVC 401 – Forage carrier

3

The gas-powered NVC 401 Forage Carrier is the latest ship design from the award-winning Rolls-Royce Environship range and incorporates a variety of features to reduce environmental impact while increasing efficiency. Ordered by Norwegian company Eidsvaag AS, it will undertake feed supply duties to fish farms along the Norwegian coast when delivered in 2013. The 75m long vessel can carry up to 1,450t of feed pellets that are stored in 62 specially designed tanks. A demanding schedule will ensure fish are fed at the same time every week, regardless of weather conditions. Rolls-Royce will supply all the main systems and equipment, as well as the ship design. These include a Bergen C26:33L9PG gas engine, a wave-piercing bow and a Promas propulsion system. Rolls-Royce will also supply the dynamic positioning (DP) system, which will hold the ship accurately in position during the offloading of fish feed via the unloading system at the bow.

NVC 386 – First for live fish transport

4

A new generation of wellboats has been designed and developed by Rolls-Royce in close cooperation with Sølvtrans, the world’s largest operator transporting live fish. The first vessel is scheduled for delivery in 2013. It will be 76m long with a beam of 16m and incorporates the latest developments in hull and systems design. An advanced diesel-electric propulsion system with hybrid shaft generator, powered by two Bergen C25:336P diesels rated at 1,440kW, will deliver low fuel consumption and emissions. The design incorporates the latest improvements in fish welfare and fish handling. Tank capacity of 3,000m3 provides a capability to safely transport up to 450t of live fish and is divided into three equal cargo holds, with sliding bulkheads and a pressure system for loading and unloading. It is fully equipped for transport in a closed system with no discharge to the sea. Control of the water flow and circulation in the cargo compartments has been a key design priority to ensure optimal conditions for the fish. Considerable emphasis has also been placed on the living and working environment for the crew. Single cabins accommodate up to 11 people and there is a fitness centre and sauna. The vessel is being built by the Spanish shipyard Astilleros Zamakona S.A. [RW] 1. NVC 405 general cargo vessel. 2. NVC 604 bunker tanker. 3. NVC 401 forage carrier. 4.

TECHNOLOGY

Stronger together Rolls-Royce and Daimler have joined forces to create a new marine and industrial engine joint venture through the acquisition of Tognum.

T

ognum makes high speed diesel engines for use at sea and on land. The engines are highly complimentary to the Bergen medium speed diesel and gas engine portfolio supplied by Rolls-Royce. Daimler has global distribution capability, volume manufacturing expertise and technologies for lower emissions diesel engines. Combining the strengths of Tognum, Rolls-Royce and Daimler will create significant new opportunities and accelerate growth in a fast-moving global market worth more than €30 billion a year. The three companies have wellaligned portfolios and together, they can offer a wide range of medium and high speed diesel and gas engines for propulsion and power generation applications. Over time,

there are also clear opportunities in shared technologies, sales networks and after sales service expertise. While the Tognum name may not be familiar to all, its brands are certainly well-known: MTU, MTU Onsite Energy and L’Orange.

Advanced marine propulsion technology What do many of the biggest mega yachts and the fastest high speed ferries of the world have in common? They are powered by MTU. The same applies worldwide for many other ships, frigates, tugs and platform supply vessels. With its two business units, Engines and Onsite Energy & Components, the Tognum Group is one of the world’s leading suppliers of engines and propulsion systems for off-highway applications and of distributed energy systems. The product portfolio of the Engines business unit comprises MTU engines and propulsion systems for ships, for heavy land, rail and defense vehicles and for the oil and gas industry. Products of the Onsite Energy & Components business unit include distributed energy systems of the brand MTU Onsite Energy and fuel-injection systems from L’Orange.

Under the MTU brand name, propulsion system solutions are provided for a range of marine applications, from naval and governmental vessels, tugs, offshore vessels to fast ferries and yachts. The high speed marine diesel engines Series 60, Series 396, Series 4000, Series 1163 and Series 8000 cover a broad power range from 260 to 9,100 kW. As a systems partner, complete propulsion packages are also supplied that include other equipment such as gearboxes, propellers, onboard power supplies and integrated ship automation systems. The range of products is complemented by extensive services provided under the MTU_ValueCare programme. In 2011, Tognum generated revenue of nearly €3 billion and 1

employed more than 9,000 people. With strategic hubs in Friedrichshafen in Germany, Detroit, Michigan in the US and Singapore, a point of contact is always within reach for customers or business partners. Its global manufacturing, distribution and service structure comprises 23 fully consolidated companies, more than 140 sales partners and over 500 authorised dealerships at approximately 1,200 locations.

Propulsion solutions for naval and coastguard vessels For more than 50 years, MTU has developed specific propulsion concepts for the naval sector. As a single source integrator, MTU configures the propulsion systems that include automation systems like ‘Callosum’ that best fit the requirements of navies and coast guards worldwide – from the Turkish MILGEM frigates – to the US Coast Guard’s National Security Cutters. Combined propulsion systems link several fuel-efficient diesel engines, or diesel engines with gas turbines to provide the needed flexibility, agility and redundancy. Highly advanced modern naval vessels like the US Navy’s Independence-variant Littoral Combat Ships – designed by a General Dynamics and Austal team – are the first naval vessels in the world to feature a trimaran hull. They rely on a combined MTU diesel and gas turbine propulsion system for efficient operations. MTU has also been playing an important role in the development and design of diesel-electric submarine propulsion systems. The Series 396 is the most successful MTU submarine engine. It is currently installed in most of the world’s conventional submarines such as the German U212, where it generates power for both main propulsion and on-board utilities. Proven engines are also the key when it comes to cost, effectively extending a vessel’s operating lifetime. The Colombian Navy recently modernised its four Almirante

The headquarters and main manufacturing is based at Friedrichshafen in Germany.

MEDIUM AND HIGH SPEED ENGINES IN AN EXTENDED RANGE The new entity will bring together the well-known MTU and Bergen engine names, extending the product portfolio to include both medium speed and high speed diesel and gas engines. Once integrated with the extensive range of Rolls-Royce ship designs, systems and equipment, a much broader range of advanced marine solutions will be available for customers across the commercial and naval sectors. The goal is to provide the optimum system where economical and reliable performance, environmental compliance and power density are important factors.

The new joint venture will provide: An integrated high and medium speed engine portfolio. A broader product range for marine and energy markets. A greater range of marine propulsion and power systems solutions. An enlarged distribution and service network. A customer and service focused organisation. At present, all three companies are engaged in discussions to prepare their future collaboration. Established individual sales relationships remain unchanged.

Padilla class frigates by replacing the vessels’ 30-year-old MTU Series 1163 engines with the current version of the same engine model. This included the ‘Callosum’ ship monitoring, automation and control system, which will extend propulsion system overhaul period to 20 years. The on-board power generation systems were also replaced with MTU gensets based on Series 2000 engines. Opting to modernise this frigate class with MTU engines, the Colombian Navy was able to make the most of existing assets and facilities.

MTU engines for tugs - reliable and durable MTU’s Series 4000 ‘Ironmen’ engines, which have a power range of 746 – 1,840kW for unrestricted continuous operation and up to 2,240kW for vessels such as crewboats, were developed to meet the particular requirements of the workboat market. Specifically, this means maximising engine performance, extending the time between overhauls and reducing fuel consumption. As a result, the ‘Ironmen’ engines deliver a fuel consumption of 195g/kWhr and can operate for up to 33,000hrs before the engines are due a major overhaul – key advantages for tugs and other commercial vessels that depend on reliable

and cost-efficient propulsion solutions with the highest possible availability. In a large number of tug systems, MTU diesels are driving Rolls-Royce azimuth thrusters.

Power offshore The ‘Ironmen’ engines are also the base for MTU’s diesel-electric propulsion systems in the offshore sector. An example is the PSV Eldborg, which is powered by four 12 cylinder 4000 M40B engines rated at 1,560kW and delivered in 2009. Vessels in the offshore wind industry also benefit from MTU’s diesel and diesel-electric solutions. Two of the most recent windfarm support vessel designs feature MTU diesel and Rolls-Royce waterjet propulsion (see page 53). Installing bulky wind turbine towers in rough seas is a real challenge for a workboat’s propulsion system. RWE Innogy’s latest installation vessels are equipped

with an MTU diesel-electric system for dynamic vessel positioning and reliable operation of all ship systems in powerful tidal currents and at high wind speeds. It is due to these advanced engine technologies that MTU’s diesel-electric propulsion solutions have since drawn the attention of a number of international naval architects.

High-performance engines for fast ferries In order to quickly and reliably transport commuters and tourists to their destinations, fast ferries depend on powerful propulsion systems. MTU has been providing shipyards such as Austal with the solutions to meet increasing demands on new vessels, which have to carry more people while completing their routes to the same schedule. Large modern high-speed catamarans like the Jean de la Valette and the trimaran ferry Benchijigua Express are powered by the largest engines MTU produces, the power-dense 8000 series. Both vessels are also propelled by Rolls-Royce waterjets. In combination with comprehensive maintenance contracts, the fast ferries are well-equipped to meet any current and future requirements.

State-of-the-art yacht propulsion The experience and expertise gained from naval and commercial applications have been incorporated into the design of MTU’s yacht propulsion systems. This results in MTU yacht engines not only being extremely powerful, quiet and compact, but also fuel-efficient, cost-effective and reliable. As a systems supplier, MTU integrates all components based on the clients’ most exclusive demands – from the engine as the heart of the system

to the transmission and generators to the standardised electronic monitoring and control systems like ‘Blue Vision’. Drive solutions are individually designed for each yacht. Italian manufacturer Ferretti, for example, relies on MTU Series 2000 engines for best in class power-to-weight ratio. Semi-displacement yachts like those of Dutch builder Heesen are equipped with Series 4000 engines for especially high standards with regards to noise, vibration and reliability.

Implementing key technologies The manufacture of diesel engines for marine applications at MTU has a long tradition. Fast-running and compact four-stroke diesel engines have been developed and manufactured since the 1930s. The most significant challenge in the development of next generation diesel engines is compliance with future exhaust gas emission limits, while also ensuring low fuel consumption. Tognum develops key technologies for clean and efficient diesel engines in-house. By combining turbocharging, fuel injection, electronic monitoring and control systems, in addition to advanced combustion technology, Tognum engineers have optimised the in-engine technologies to the point where no additional external after treatment is necessary to comply with today’s emission standards. If in-engine optimisation is no longer sufficient to meet the more stringent emission requirements, then exhaust gas after-treatment such as selective catalytic reduction (SCR) or a diesel particulate filter (DPF) is added. As a result, system solutions deliver minimised fuel consumption with low exhaust emissions and long engine life. [MG]

Anti-heeling

with simultaneous roll-reduction Rolls-Royce can now provide anti-heeling and roll-reduction in a single system. Crane operations at sea can therefore be carried out on more days than previously possible.

1

R

olls-Royce has been designing U-tanks for rollreduction and anti-heeling (formerly Intering) for over 40 years. These systems have proved so reliable that in some places they have become the accepted standard for shipyards and shipping lines. A particular speciality is the combined U-tank. Roll-reduction during operations at sea and anti-heeling in harbour can be carried out with the one tank, saving significantly on space. The principle has been proven with installations on several hundred ships, but until recently, it was only possible to select one of the functions, depending on requirement. The next logical step – anti-heeling with simultaneous roll-reduction – has now been successfully realised, with installations on the ROV/dive

support vessels Deep Cygnus and Normand Pacific, and feedback is good. They are no longer forced to wait for sea conditions almost as calm as in harbour before commencing lifting operations. The key to simultaneous operation is a multi-tank system of adequate tank capacity and momentum for both applications. Since in most cases the tank capacity is designed according to the maximum crane moment, simultaneous operation can only take place with the crane under part load, so that sufficient tank moment still remains for roll-reduction. These vessels each have three U-tanks. In normal mode, when crane operations are not being undertaken, all three tanks operate in roll damping mode. When crane operations are being carried out, one or two of the tanks are switched to the anti-heeling mode, depending on the sea state and the load being lifted. Both systems are designed for operation with maximum reliability and minimal energy consumption. There are no moving parts in the water. For ice breakers, the system gives another benefit, ice heeling or duck walk, where the system is set to give the vessel a gentle roll of 3-4 degrees in a three-minute cycle. This ensures a regular change in waterline depth

to keep the sides of the vessel wet, thereby reducing external ice build-up and increasing speed. A wider channel is also created.

Roll-reduction The directly controlled U-tanks (wing tanks measuring approximately two to three decks in height, connected to each other by water and air cross-ducts) are designed to meet the shortest roll that can be expected from the ship during its normal operations. The movement of the tank water is passive, induced solely by the rolling movement of the ship, and the system maintains its full effect ff ffect even at zero speed. The shifting of the centre of gravity, which is the difference fference in level between the ff two wing tanks, generates the tank momentum that counteracts the roll motion.

With periodic interruption of the tank’s ventilation using a series of durable disc valves that open and close within 0.4 seconds, the tank moment can be held constant. The system can therefore react automatically to every individual roll movement of the ship. This control mode preserves the necessary delay of ¼ roll period, i.e. 90° of tank period versus the ship roll motion, in each single roll movement for the best possible reduction of roll. The tanks are usually positioned in the parallel mid-ship area, where the leverage is greatest for the tank moment and therefore the required mass is smallest. If this is not possible, the tank can be moved aft. Moving forward is undesirable as acceleration forces from pitching should be avoided inside the tank.

Anti-heeling The anti-heeling action is achieved using the same tank but by means of an air blower, which acts on the water surface with a maximum over-pressure of 1Bar. The airflow is controlled by a special valve group, which can switch to any operating condition (water to starboard, to port, or stop) in less than one second. The system therefore reacts almost instantaneously to the current heeling moment. This is particularly useful if the moment of the crane does not change linearly, but resembles a sine-function. As air pressure is the weight transfer medium, the cross-duct no longer has to be tubular and a roll-reduction tank with its large and rectangular cross-duct can be used for anti-heeling duties. A further control option, already proven on paper-carrier vessels, reduces system reaction time even further. By programming the anti-heeling system to receive change of momentum (tm/min) signals directly from the crane reaction is immediate, no waiting for the delayed reaction to the ship’s list. In the ideal case, no further list occurs at all, since every crane movement is compensated for instantaneously by the

anti-heeling system. Depending on the vessel application customers can select from a number of anti-heeling arrangements. Now that Rolls-Royce has become a major producer of shipboard cranes for demanding tasks offshore, ffshore, as well as a ship designer ff and provider of anti-roll and anti-heel systems, fully integrated solutions can be designed and supplied. A combined system allows crane operations to continue safely, even in worsening weather conditions, for more operational revenue-earning days. [RW]

Venice Syncrolift

demonstrates step change in shiplift lift capacity The highest capacity Syncrolift® ever designed by Rolls-Royce was recently commissioned in Venice. It sets a new standard in tonne/metre lift capacity and means shiplifts can now be designed to lift Aframax size vessels.

W

ith a platform width of 52m and a length of just 60m, the Venice Syncrolift is the widest shiplift designed and constructed to date. Two rows of 1,200 tonne hoists give the shiplift a net lifting capacity of over 24,000 tonnes – the greatest tonne/metre capacity of any Syncrolift in the world. This latest advance in the application of Rolls-Royce shiplift technology is now operational in Venice, Italy and is a revolutionary departure from standard Syncrolift designs. It will launch concrete caissons, not ships. The Syncrolift was custom designed to meet the requirements of the Venice flood barrier project, known as MOSE. It will be used to launch 18 giant concrete caissons, fabricated by Grandi Lavori Fincosit (GLF), that will become the seabed supports for the barriers being constructed in the inlets of Venice’s three lagoons. When complete, huge gate-like barriers will be anchored to the caissons mounted on the seabed and will protect Venice from high waters that are increasingly threatening the city. The full-scale operational trial launched a 7,000 tonne test caisson and proved all aspects of the caisson preparation, transportation and launch process. It was

completed by GLF and Rolls-Royce engineers in less than eight hours. Although the test caisson launched into the waters of the Venice lagoon weighed as much as a small warship, it was one-third of the weight of the largest caisson that will be launched. The MOSE System that will safeguard Venice from high waters consists of a series of gates that can be raised to separate the lagoon from the sea. They are being constructed at the lagoon inlets of Lido, Malamocco and Chioggia, the three openings in the barrier island through which tides propagate in the lagoon. In normal tidal conditions, the gates (a type of pontoon) rest in the caissons anchored on the seabed in the inlets. They are completely invisible and do not require modifying exchanges between sea and lagoon. During high waters, they will be raised to prevent the tide from entering. At present, the tidal level at which the gates will be raised has been set at 110 cm, the level which Venice has been protected by raising quaysides and paving. Venice and the lagoon will be protected from tides of up to 3m and will therefore be effective even if the level of the sea rises significantly. The MOSE system is the last and most important element in the plan of measures implemented by the Ministry of Infrastructure and Transport – Venice Water Authority through the Consorzio Venezia Nuova to safeguard the Venice lagoon area. GLF will fabricate and install a total of 18 caissons on the seabed, with the largest weighing 22,300 tonnes. Derived from the successful and proven Syncrolift shiplift and transfer system technology, typically used for docking and undocking ships, the new Rolls-Royce caisson lift takes shiplift capability to a new level. With the integration of 1,200 tonne hoists, it has been possible to virtually double Syncrolift lift capacity. This, coupled with the development of the much wider 52m platform, will enable Syncrolifts to be constructed with capacities to safely dock and undock much heavier and wider ships, including Aframaxes and cruise ships, thereby providing a viable alternative to drydocking for major ship repairers. The Syncrolift design is also very flexible, so longer ships can be accommodated by simply extending the platform length and adding more hoists. As the world leader in shiplift and transfer systems with more than 245 installations designed and supplied to over 70 countries around the world, Rolls-Royce is looking to apply greater lifting power to other applications, and improve operational flexibility for customers with diverse docking needs.

Safe and efficient

deck operations with new crane technology

The Rolls-Royce range of advanced, precision heavy lifting tools, primarily for offshore vessels, vessels. continues to expand.

www.rolls-royce.com

O

ver the past few years, Rolls-Royce has developed and put into service a range of deck machinery to make work on the decks of offshore anchorhandlers safer for the crew. The same has been done for platform supply vessels that have to load and discharge cargo at rigs and platforms, often in rough sea conditions. This work continues, with a number of new systems under development or specified for vessels currently under construction. With the acquisition of Odim and new agreements with partners, Rolls-Royce has been able to rationalise and expand its marine crane activities. Rail-mounted cranes for supply vessels and anchorhandlers are a feature of many vessels equipped by Rolls-Royce, with over a hundred now in service. They can be fitted with remote controlled manipulators to make anchor handling operations involving chains and wires under high tension far safer for the deck crew.

The latest development is in the crane itself, with the introduction of the active heave compensated (AHC) dual draglink crane. A special parallelogram linkage formed by the boom and two links, allows the hook to be positioned anywhere in a much larger working envelope than the alternative knuckleboom layout. Other advantages include increased lifting height, efficient vertical and horizontal load handling with good heave compensation. The crane itself has a low centre of gravity and is light for its power and capability. The first crane of the 50t active heave compensated dual draglink type is being supplied to Olympic Shipping. It can handle 50t loads at an outreach of 8m, or 20t on a 20m arm. The active heave compensation system allows for substantial movements either side of nominal. A version designed specifically for platform supply vessels (PSV) is also ready for delivery and will be fitted to the UT 754 WP now being built for Farstad Shipping. Two types of crane – knuckleboom and dual draglink – each have advantages and applications and both are being manufactured and further developed. Feedback on a 150t knuckleboom crane with heave compensation delivered to Havila Subsea has been positive and two other cranes of this configuration are now going into service. With offshore construction work in deep water growing rapidly and operations in 4,000m depths becoming increasingly the basis for specifications, the application of fibre rope is gaining ground as the limits of steel wire is reached. Fibre ropes require special

25

handling, for which Rolls-Royce has developed the CTCU traction winch. It has proved very successful, both technically and in terms of operating economics. This fibre rope handling technology is now being incorporated into Rolls-Royce cranes, giving sensitive load control in ultra deep water with very effective heave compensation. The same technology is also being used successfully for oceanographic research. [RW]

World’s largest maritime territory The European Union countries, collectively, have a coastline seven times that of the US and four times as long as Russia’s. When outlying regions are included, the EU also has the world’s largest maritime territory. Europe was the base for world maritime exploration over the centuries and is now the home to some of the world’s biggest merchant shipping fleets, with names such as Maersk, MSC and P&O all based in European waters while plying their trade across the globe. There’s no surprise, then, that the maritime industry is a significant driving force in the economies of Europe, playing a key role in the movement of people and cargo, fishing, energy production and of course, in the defence of nations through significant naval capabilities. Around 40 per cent of all freight moved in Europe, is classed as Short Sea Shipping, meaning many of hundreds of vessels moving a wide variety of products over a complex network of trading routes 365 days a year. Europe is also the base for many of the world’s leading ship designers and manufacturers of highly advanced marine equipment. While ship building volume may have declined sharply in the last 25 years, there are still around 200 yards in Europe building ocean-going vessels, while many yards are serving the growth in demand for ship repairs. Despite recent economic turmoil in many European countries, the shipping industry plays a significant part in the way continental countries do business with each other and the rest of the world. Rolls-Royce

is investing to provide support across all sectors of the industry in this hugely diverse region.

Supporting European shipping across the globe In recent years, Rolls-Royce has invested significantly in a network of state-of-the-art marine service centres across Europe, with new or expanded facilities opening recently in Rotterdam, Genoa, Hamburg and Gdynia. In addition to the larger service centres, even greater geographic coverage is maintained through an extensive team of service engineers, many working from local dedicated offices, such as those in Greece, Spain, France and Turkey. “We mustn’t forget that Europe is by far the world’s largest ship owning region, and with those owners operating across the globe, we can support them through our global service network covering 35 countries,” says Martin Hall, SVP, Services – Europe. “Owners choose to carry out maintenance work at whatever yard offers the optimum and most cost effective solution, and at a time that fits operating schedules, so we actually work with our customers worldwide, offering a consistent level of support.” In Europe, Rolls-Royce has a mix of fixed and mobile service capability, covering an area from the eastern Mediterranean to the Atlantic coast, the Baltic and Nordic region.

A network of convenient, fully equipped facilities in the major ports are supplemented by mobile engineering capability in the shape of containerised workshops, which can be deployed exactly where and when they’re needed.

Mediterranean The Mediterranean is dominated by the Merchant sector with an abundance of cruise ships and ferries catering to millions of tourists, and cargo ships of all classes serving the numerous ports, ranging from Istanbul, Naples and Genoa, to Barcelona and Marseille. However, the merchant sector is not completely dominant. Italy is one example of where Rolls-Royce also has broad coverage across the naval and offshore sectors, with FF waterjets powering the Navy’s V2000 fast attack craft – a fleet which will total 100 boats – and one of the world’s largest offshore companies Saipem, operating Rolls-Royce

designed UT vessels. The Rolls-Royce marine service centre in Genoa, Italy, is a hub for activity in the region, and as site manager Stefano Lavezzaro explains, the facility has become popular with customers, since opening in 2009. He says: “Italy is one of the world leaders in the design and construction of luxury yachts. This is a key market for our smaller Kamewa waterjets and since the opening of the Genoa service centre, we are seeing many customers choose Rolls-Royce for overhaul of these components during the winter months. We have around 600 of the small waterjets in service in the region.” “We also have azimuth thrusters on tugs in all the major ports, and have close relationships with the three main tug builders in Europe. We have around 50 per cent of the Mediterranean market for tug propulsion.” The cross-sector spread is similar in France, where Bourbon, another of the leading offshore companies is an operator of a sizeable fleet of Rolls-Royce UT vessels, deployed in oil fields around the world, as well as ocean going tugs stationed around the entire French coastline. The French Navy uses Rolls-Royce equipment, such as Mermaid Pods and stabilising fins on the Mistral class amphibious assault ships and propellers on the aircraft carrier Charles de Gaulle. Turkey has a buoyant shipping industry, together with a maritime cluster of more than 50 shipyards around

Istanbul. Rolls-Royce has established an office in Tusla, in the heart of Turkey’s ship building and repair industry. The city’s main ferry operator, IDO, is Europe’s largest ferry operator by passenger number, moving a colossal 100 million people every year. Fifteen of IDO’s fleet use Rolls-Royce propulsion products including Kamewa waterjets and Azipull thrusters. Turkey’s Navy is embarking on a major expansion over the coming decade, with more than 100 new ships proposed. Many of these platforms will be suited to Rolls-Royce propulsion systems and discussions continue between the company, shipyards and the Navy.

North and West Europe has a significant number of specialist design and production facilities, each focused on specific areas of marine technology. In the UK, Rolls-Royce provides technical leadership in relation to a number of products including marine gas turbines, replenishment-at-sea systems, electrical power and control systems and thrust and propulsion shaft line bearings. Bristol is the European headquarters for the Rolls-Royce Naval business. The range of marine gas turbines is developed here, with the MT30, the world’s most power dense, designed, assembled and tested on site. The Naval team specialises in systems integration offering bespoke packages suited to customers’ requirements. A dedicated

REGIONAL FOCUS

naval ship design team has recently been established. In Newcastle, the Rolls-Royce Michell Bearings business manufactures shaft line bearings and thrust blocks for a range of commercial and naval customers. Replenishment-at-sea systems are also designed at the site. At Portsmouth, close to the UK’s largest Naval base, the Rolls-Royce Marine Electrical Systems business specialises in low voltage control systems used predominantly in naval ships and submarines. Further north in Scotland, a major investment in service capability has seen the establishment of a hub for diesel engine repair and overhaul at Dunfermline. The facility is also a centre of excellence for motion control systems, designing and manufacturing retractable and fixed fin stabilisers. It is currently involved in the manufacture of underwater tidal turbines for a demonstration project off the Orkney Islands. The UK has a burgeoning market in offshore wind farms and a number of smaller yards are developing innovative designs for support and crew boats. Rolls-Royce is supplying increasing numbers of waterjets to many of this new class of vessel in a market that is set to grow with increased use of renewable energy in UK waters. Europe’s largest port, Rotterdam, is home to one of the largest Rolls-Royce marine service centres. The facility has recently undergone a major expansion, which has doubled workshop space to 1,500m2 and the introduction of the latest equipment used in the servicing marine products.

Southern Baltic Last year, Rolls-Royce opened two new service centres in mainland Europe, Gdynia, near the southern Baltic port of Gdansk in Poland, and Hamburg on Germany’s North Sea coast (see page 31). These new world-class facilities are designed to provide significantly more workshop space with the capability to handle and overhaul the larger items of Rolls-Royce marine equipment. They are located close to the waterfront, which puts the local service teams

close to the ship repair yards, simplifying communications and ensuring the prompt supply of parts and labour.

Naval capability – mission critical across Europe The UK Royal Navy is the largest European naval user of Rolls-Royce equipment that powers a wide range of vessels from the entire fleet of nuclear powered submarines to the latest Type 45 Daring class destroyers. A major part of the propulsion system for the two new Queen Elizabeth class aircraft carriers is being supplied by Rolls-Royce. The company pioneered the development of the marine gas turbine more than 50 years ago and subsequently developed engines such as the Tyne, Spey, Olympus, WR-21 and today, the MT30. Most of Europe’s navies operate Rolls-Royce equipment in their fleets, and gas turbines are also in service with France, The Netherlands, Greece, Belgium, Bulgaria and Romania. The naval shipbuilding industry in Western Europe has an enviable heritage. Technical prowess means these yards are still delivering some of the world’s most advanced warships. Many commercial yards are now building naval ships, leading to a growing cross over in technology from the merchant and offshore sector, and Rolls-Royce has established links with such yards, many of which are experienced in building and installing Rolls-Royce designs and equipment.

A future of challenges and opportunities The coming years will witness massive change for global

shipping as proposed environmental legislation becomes a reality. As an Emission Controlled Area (ECA), the shipping across the entire region will be subject to allowable sulphur emissions of less than 0.1 per cent, meaning technologies such as the Rolls-Royce range of lean burn gas engines will see a growth in demand. The need to comply with such tough restrictions is seeing more owners turn to environmentally friendly solutions, which in turn is driving technological advances across the industry and indeed Europe. Rolls-Royce continues to invest heavily in R&D, and with the world’s largest range of marine products, the Group will be at the forefront of developing the solutions that will transform shipping in Europe and beyond.

New European Service Centres

up and running 1

New and enlarged service facilities in Hamburg and near Gdansk in Poland are enabling Rolls-Royce to provide a broader range of services in the region

L

ast year, Rolls-Royce opened two new service centres in mainland Europe, Gdynia, near the port of Gdansk on the southern Baltic and Hamburg on Germany’s North Sea coast. Every year, around 60,000 ships enter or leave the Baltic Sea, so these world-class facilities are equipped to provide a significantly enhanced support capability for customers who operate from or use these centres for ship repairs.

Gdynia, Poland Officially unveiled in 2011, the Gdynia facility is located in one of Europe’s largest ship repair yard clusters and is equipped to support and maintain the extensive range of Rolls-Royce products in service in the Baltic. The site benefits from having direct access to the waterfront with ease of access to nearby repair yards, serving a variety of customers from the commercial and offshore sectors, as well as the Polish Navy. Rolls-Royce has operated a manufacturing facility in Gniew, Poland, for over a decade, producing winches for merchant, fishing and offshore vessels, and the safer deck equipment range for offshore vessels. The Gdynia facility now increases capability in Poland to service a wider range of products that includes diesel and gas engines, thrusters, steering gear and propellers. It also has the specialist machining capability to provide a range of additional services that include propeller blade polishing and root machining. “Poland is an important market for Rolls-Royce and this is reflected in our decision to develop a major new facility in Gdynia, one of the Baltic’s busiest ports,” says Martin Hall, SVP, Services – Europe. “This will help our customers maximise availability of their vessels by giving them access to highly skilled service engineers and state-of-the-art workshop facilities.” The site comprises 1,000m2 of workshop, stores area and office space, and has space to accommodate future expansion. Workshop height and crane capacity

have been designed to cope with the largest thrusters and equipment. In addition to providing service engineers with a range of servicing and maintenance skills across the Rolls-Royce product range, the facility is also the base for new equipment sales and spare parts for the Baltic region. The larger Gdynia facility replaces the smaller service office formerly located in the city. By 2014, around 60 service engineers are expected to be operating from Rolls-Royce Poland facilities.

Hamburg, Germany The newest European service centre is located in the Port of Hamburg, one of the largest commercial ports in the region. Opened in September last year, the new 1,100m2 centre centralises all Rolls-Royce personnel previously working at three separate locations in the city. The workshop is well equipped with repair and overhaul capabilities for a wide range of equipment including thrusters, propellers, steering gear and winches. It also benefits from specialist machining capabilities, allowing a wide range of repairs to be undertaken in-house. The facility is also the centre of excellence for the design and manufacture of tank-based stabilising and anti-heeling systems, which automatically control water movement between tanks on either side of a ship to give balance and counteract roll in rough seas. Like Gdynia, Hamburg has a team of highly skilled engineers, available 24/7 to respond to customers’ needs throughout the region. [DC]

ewek Fulmar and Lewek Falcon are among the most powerful vessels of their type operating today. They are multifunctional deepwater anchor-handling tug supply and service vessels with many capabilities: ultra-deepwater anchor-handling, towing and supply. The specific design brief was to extend their service scope capability and as such, they can also support other tasks related to subsea construction, ROV intervention, subsea maintenance and repair work. “Central to our vision was that these new vessels would be technically complex, making the very best of available technology and able to deliver our clients’ future needs, even before they knew what those needs were,” says Robin Kirkpatrick, Chief Executive Officer of EMAS Marine. “We are continuing to expand globally, to markets outside Asia where complex vessels are the norm, so the ability to safely undertake deepwater and harsh environment operations was at the forefront of our decision to invest. We took the view that only companies able to meet the exacting demands of harsh environment deep water operations and able to satisfy ever more demanding clients would continue to be successful,” adds Kirkpatrick. “Early on, there was a lot of dialogue between Rolls-Royce and ourselves, as we worked out the key design and performance parameters. Minimising the vessel’s environmental impact and maximising crew safety and comfort were high on the list.”

Powerful and capable

Meeting these demands requires sizable and powerful vessels, 93.4m long overall, 22m beam with a max draught of 7.87m and over 25,000kW of installed power and the largest bollard pull ever achieved from a vessel built in Asia. The 815m2 of deck area is strengthened for heavy cargoes and ensures all the normal supplies can be carried up to a deadweight of 4,700 tonnes. Built to Lloyd’s Register LRS +100A1 class with DP (AA), the vessels meet Lloyd’s Register Environmental Protection (EP) requirements for reduced emissions and water pollution risks. Double skin construction protects fuel tanks and potentially polluting cargo in the event of collision or grounding. With its full outfit of Rolls-Royce equipment and systems the UT 788 CD offers impressive capabilities. The main hydraulic winch has three drums for different tasks. The anchor-handling drum can pull 500 tonnes and the two towing/working drums have pulls of 450 tonnes and can hold 750 tonnes on the brake. All have a large wire capacity and large rig chain lockers provide for ultradeepwater anchor-handling. The main winch is complemented by secondary winches and deck equipment for safely handling wires and chains. An installed ROV hanger suitable for a work class ROV complete with control office is incorporated in the hull design. Lewek Falcon additionally has a 150t active heave compensated knuckle boom crane aft and a second work class ROV on a mezzanine deck. Sister ship Lewek Fulmar has a 350 tonne capacity A frame in way of the stern which uses the existing

www.rolls-royce.com

Rolls-Royce winch set up, so that work like the handling of torpedo anchors can be safely undertaken. Crew safety, another key requirement, is enhanced by the Rolls-Royce Safer Deck Operations systems. Remote controlled travelling cranes and manipulators, pennant wire winder and other equipment are used to reduce the risk to sea staff during operations.

Hybrid system savings Depending on the type of operation, the UT 788 CD can run in any of six principle propulsion modes. This caters for the large differences in power demand in the various operating modes to both cut fuel consumption and reduce emissions. Two 8,000kW main engines drive the propellers and also generate electricity. They can be used in various combinations with the four 2,230kW auxiliary generator sets to give a diesel mechanical or diesel-electric system, providing power in the most efficient way for propulsion, manoeuvring and for the deck and hotel electrical modes. Electric motors supplement the main engines when high power is required on the propellers. Conversely, two retractable azimuth thrusters deliver low speed with very low fuel consumption and provide part of the dynamic positioning capacity. “In diesel-electric mode the fuel cost saving is exceptional, up to 71 per cent compared to diesel mode at the same output”, says Michael Petersson, Fleet Manager, EMAS Marine, “with a respectable bollard pull of 158 tonnes”. “The diesel-electric mode is utilised particularly during voyage, standing by, towing and shallow water anchorhandling. As a result, running hours of the main engines is reduced between 50-80 per cent depending on charter requirements. Further savings will also be achieved in maintenance and spare parts costs. Clients also benefit through significantly reduced fuel costs”. The first job the Lewek Fulmar undertook in 2011 was for a client Offshore India, laying out rig moorings. Although a relatively small project, due to improved 4

stability and a larger deck area, it was possible to get everything done in a single trip, a few days ahead of schedule, working to world class safety standards. The second job was the successful installation of the co-owned FPSO Lewek EMAS for Vietnam’s Chim Sao oil project, a job well within the vessel’s capability. The job demonstrated the full suite of services provided by the EMAS group with EMAS Production converting and operating the FPSO, EMAS AMC installing the FPSO, EMAS Energy doing the well pre-testing and EMAS Marine supporting the entire project. Having complex vessels and projects means there is a need for a highly competent crew able to get the best from the vessel. These UT 788 vessels provide greater crew comfort and attention to safety, which helps to both attract and retain staff as the new vessels create a very positive working environment. This, coupled with EMAS’ commitment to staff training and development, such as evidenced by the company’s commitment in its $10M EMAS Training Academy and Simulation Centre, makes a powerful combination. “These vessels are niche, deepwater capable and I believe this is the first time a Singapore based company had made a real commitment to complex vessels of the standard found more typically found in the North Sea for example,” says Kirkpatrick. “With a complex vessel, you have the ability to trade down to maximise utilisation and hybrid propulsion gives us the flexibility to market the vessels into different roles. More capability can deliver projects quicker with greater safety, potentially lower costs and a much reduced environmental footprint,” adds Kirkpatrick. “Ensuring our customers understand these key differentiators is our next challenge but is a challenge that we relish taking on.” Lewek Fulmar has now commenced a multi-year contract with a major client in Brazil and Lewek Falcon is now working full time for EMAS AMC, EMAS’s growing subsea construction division that has over 40 years of collective experience in design, construction, transportation and installation work.

Working together to reduce weight and

enhance efficiency

The projected target weight has been achieved for a new series of five 37m Australian catamarans, and the tailored installation of the latest generation Rolls-Royce aluminium waterjets is a key factor in overall vessel performance.

A

chain is never stronger than its weakest link. Therefore, to build a fast ferry with fuel consumption that is an improvement over the industry standard requires real team work from the designer, shipyard and equipment suppliers through to the customer. During recent sea trials of the first vessel, Capricorn Dancer, that teamwork has been proven to deliver, with lower fuel use per passenger than a small four cylinder car for low environmental impact. Using the latest CFD analysis, FEA and 3D structural/ systems modelling tools, the design is both light and very efficient, giving a low resistance with a minimal wake and wash. The designer of the new ferries is One2Three Naval Architects. As the catamarans will operate in an Australian marine park environment, where endangered Dugongs live, the hull is engineered to have no external protrusions, with a rounded profile to create a minimal impact zone, together with a very shallow draught of 1.3m with no keel or external raw water intakes.

The catamaran is Brisbane shipbuilder Aluminium Boat Australia’s largest to date and has been built on time, to budget and meets the very ambitious weight goals set by the designer at the outset of the project. Even the paint selection reduces weight. Vinyl was used on the superstructure for its eye catching appearance. Offering a life span two to four times of normal paint, it is also considerably thinner, contributing to the weight saving. The key systems integrator for the shipyard, supplying all the electronics, as well as the gearboxes and waterjets, is Ultimate Marine Power. Four of the newly developed Kamewa 40A3 series waterjets were

selected for propulsion, each driven by a separate 515kW diesel. As well as offering ffering the highest efficiency ff on the market, the waterjets have a stainless steel mixed flow pump for long service life and low maintenance costs. Even though key pump components are stainless steel, the Kamewa units are still very light, weighing less than comparable axial flow waterjets. The Kamewa A3 series of waterjets also feature a newly developed steering nozzle and reversing bucket, greatly improving steering and reversing efficiency. This, together with the improved pump performance characteristics, means that power in reverse

can be reduced by approximately 30 per cent, while still delivering the same manoeuvring force as its predecessor, adding to the vessel’s overall fuel efficiency. “To assist the yard and designer in their weight saving efforts fforts and reduce installation time, we were able to ff put both waterjets for each hull on a single base plate, the full width of the hull,” says Joakim Adamsson, sales manager. “This enabled us to include the stiffeners ffeners as ff required to maintain the hull stiffness and strength, while reducing the stiffeners ffeners required for the waterjets ff themselves, which resulted in a weight saving of five to 10 per cent compared to a conventional separate waterjet installation. We were also able to move to composite shafting within the Rolls-Royce scope of supply, which reduced the weight of the couplings and shaft by almost 50 per cent.” In addition, an interceptor and active ride control system from Humphree was supplied. This interceptor system has an automatic trim optimisation system and once set, ensures that the vessel always operates at its most favourable trim, minimising the power demand. At the contract speed, the interceptors brought down the power demand by 20 per cent. However, the effect ffect of the ff interceptors was already included in the naval architect’s resistance estimates, based on previous experience. To ensure accurate and easy installation of the interceptors, an adaptor plate was also part of the Rolls-Royce supply and was designed and fitted in cooperation with Ultimate Marine Power. All hull penetrations were made at the factory. The quad engine and waterjet system delivered a maximum speed in trials of 36 knots, though the Enviro Cat’s operating speed will be restricted to 25 knots due to harbour restrictions on the route. When transiting at low passenger loads, fuel consumption and emissions are further reduced as two engines can be shut down while still maintaining the required speed. The ferries provide high passenger comfort and will be able to keep to schedule on three engines, which provides exceptional redundancy for operators. In normal operation, only 75 per cent power is needed on each jet

to give the required service speed, which should result in good engine life and extended time between overhauls. The first three of the 400 passenger Enviro Cat ferries have now been delivered to Transit Systems Australia, who place low operational costs and redundancy high on their list of requirements. It will operate five of these ferries on the LNG project between Gladstone Harbour and Curtis Island on the central Queensland coast. [AR] 1. The new Kamewa A3 series waterjets confer excellent manoeuvrability and have much improved reversing efficiency. For the same manoeuvring force, much less energy is required for lower fuel bills. 2.

Propelling and positioning drillships As the search for new reserves of offshore oil and gas moves into very deep waters, operators are continuing to invest in dynamically positioned units that use multiple azimuth thrusters to remain on station.

rillships and semi-submersible rigs are designed to undertake drilling operations in waters that can be over 3,000m deep. However, drillships are able to propel themselves from well to well, unlike most semi-submersible rigs that must rely on transport ships or towing to change location. Therefore, in an industry where “time can be measured in thousands of dollars”, there has been a growing take up of drillships. Rolls-Royce provides the thrusters for both types of rig and has an established reputation as the main player in the market. As the rig owners invest more and more in drillships, the excellent track record built up by these sturdy Rolls-Royce azimuth thrusters has resulted in them being selected for a number of drillship newbuilds. “In the course of 2011, eleven different fferent companies ff have ordered a total of 21 drillships and have specified Rolls-Royce thrusters,” reports Helge Gjerde, Senior VP for offshore ffshore engines and propulsion. “All the vessels are to be ff built by yards in South Korea, with deliveries scheduled from this year and out to 2014. The customers include Seadrill, Noble, Atwood, Ocean Rig, Pacific Drilling, Vantage, Fred Olsen, Pride (now part of Ensco) and Aker Drilling (now part of Transocean).” The thrusters selected are the Rolls-Royce UUC-series that can be mounted or removed for service underwater, without drydocking the drillship. This results in significant time saved when a thruster exchange is required. Each vessel will have six thrusters, normally three in a triangular layout at the bow and three in a similar arrangement at the stern. Thruster frame size and power varies from vessel to vessel within the 4,500 – 5,500kW power range per unit and fixed pitch propellers are specified. When working at great depths, drillships will always be operating in DP mode without anchoring. As they are large and susceptible to wind and waves, this places a heavy demand on thruster performance. Reliability is equally important to ensure the ship is maintained accurately in position, no matter what the weather when

drilling operations are in progress. Operators are now increasingly concerned about emissions and the environment, so these propulsion, manoeuvring and positioning demands have to be met with the minimum of energy consumption and resultant CO2 emissions. “The UUC-series thrusters are not the lightest units on the market but they win on performance and robustness,” says Jarle Hessen, General Manager for offshore ffshore E&P ff propulsion sales. “We favour large reduction ratios and big, slow turning propellers to give maximum thrust, combined with strong construction for reliability to provide a long service life.” Propulsion for drillships has been a Rolls-Royce speciality since propellers and tunnel thrusters were first supplied in 1980, multiple azimuth thruster installations grew from the mid 1990s and numerous drillships with Rolls-Royce UCC thrusters have been constructed in the past few years. Several of the vessels now on order are to the latest version of the GustoMSC P10,000 design, built under licence by HHI in South Korea. The hull is 210m long with 36m beam, displacing about 70,000 tonnes. These drillships are capable of dual activity drilling in water depths of 3,600m to a total drilling depth of 12,000m. [RW]

The UK Royal Navy’s Queen Elizabeth class aircraft carrier programme continues to forge ahead, with significant progress in the modular shipbuild and equipment deliveries during the past year.

R

The 65,000 tonne QE class carriers will provide a four acre military operating base that can be deployed worldwide and will be versatile enough to support operations ranging from war efforts to delivering humanitarian aid and disaster relief.

olls-Royce is supplying a comprehensive range of propulsion equipment and system to both ships Queen Elizabeth and Prince of Wales. On each ship, this includes two MT30 gas turbines, 7m diameter propellers with shaftlines, bearings and thrust blocks, steering gear, rudders, retractable stabilisers and the low voltage electrical system. Rolls-Royce equipment for firstof-class, Queen Elizabeth, is now completed and work on the second ship continues to be planned, with numerous Rolls-Royce facilities delivering products, tested, certified and stored ready for installation. Queen Elizabeth is due to be handed over to the Royal Navy in 2015. The ships’ hulls are being constructed in modular sections at a number of UK yards and then transported by barge to the Rosyth Dockyard, near Edinburgh. A significant milestone was achieved during 2011 when one of the largest “blocks” of the hull, the 8,000t Lower Block 03 was moved from the BAE Systems yard in Glasgow, via the north coast of Scotland to Rosyth. Sponsons and the upper deck have now been fitted to this block and the full width of the 75-metre flight deck is now clearly visible.

UPDATES

In February 2012, production of the Prince of Wales started when the first steel was cut for the forward hull section. Known as Lower Block 2, the huge section, which will weigh around 6,000t on completion, is being built at BAE Systems in Portsmouth Naval Base - the home of the Queen Elizabeth class. The Aircraft Carrier Alliance or ACA is responsible for delivering the Queen Elizabeth class carriers to time and cost. It comprises a single integrated team of BAE Systems, Babcock, Thales UK and the MOD, who acts as both partner and client. The power and propulsion system is being supplied by a sub-alliance led by Thales UK, also part of the main Aircraft Carrier Alliance. The other partners are Rolls-Royce, Converteam, now part of GE Energy and L3. Together they are responsible for the design, procurement, manufacture, integration, test and delivery of the integrated electric propulsion system.

Latest deliveries During 2011, Rolls-Royce completed all four 36MW MT30 gas turbines for both ships and the first pair is now at sub-contractor Cullum Detuners, where packaging into the steel acoustic enclosures is underway, together with the alternator, manufactured by sub-alliance partner GE Energy. The first complete gas turbine alternator package that will weigh around 75t is due to be delivered to the ship in late 2012. A successful engine removal demonstration was carried out to prove the ease with which the MT30 gas turbine, weighing six tonnes, can be exchanged when the ships are in service. The purpose built simulator included bulkheads to replicate the dimensions and clearances that are on the actual ship. The final set of Michell thrust and lineshaft bearings for the second ship, Prince of Wales was handed over recently, designed and manufactured at the Rolls-Royce Newcastle facility. For each ship, Rolls-Royce has supplied two thrust blocks and three shaft line bearings. The thrust blocks, each weighing

more than 20 tonnes, perform the essential role of transferring the thrust from the propellers into the hull to drive the ship forward. The lineshaft bearings support the weight of the propellers and the steel shafts that run through the ship and are turned by large electric motors. Due to propulsion system configuration the port shaft is the longest and supported by two bearings. The shorter starboard shaft has only one. Both types of bearing are of a water-cooled, selfcontained design using heat exchangers to maintain the fixed volume of oil in each bearing at controlled temperatures. When the shafts are rotating, a shaft mounted disc in each bearing transfers oil from the casing bottom reservoir to the top, from where it lubricates the working surfaces of the bearings. The radial and thrust loads are supported on a thin

film of oil which forms between the stationary white-metal lined bearing components and the rotating shafts. The oil film is similar in thickness to a strand of human hair, making control of the dimensional and geometrical tolerances as well as the surface finish of the bearing components critically important. One of the major challenges for the project was the size and complexity of the bearings and the stringent certification requirements for naval applications. During the handover, Jim Bennett, Power & Propulsion Director for the Aircraft Carrier Alliance, praised the

team at Newcastle and said, “The Michell Bearings site has almost 100 years of association with the Royal Navy, and this latest contract marks a significant milestone for the QE class project.” “With over 37MW per shaft to transmit, these bearings are not without challenges in design and manufacture. The team who have built them should be very proud of the part they are playing in delivering such impressive and capable ships to the Royal Navy.” Rolls-Royce is also supplying the entire low-voltage system for the ships that will provide power to the

mission systems, the auxiliary systems and all domestic services, with significant volumes of equipment completed to date. Each ship will have more than 600 individual items ranging from switchboards and distribution panels to starter boards, changeover switches and battery boxes, with over 2,500km of cabling.

“Best-for-project” ethos The team working approach of the power and propulsion sub-alliance has delivered real benefits to the programme in the building of these two 65,000t ships, with all partners adopting a “best-for-project” approach to overcome challenges and optimise delivery. David McConnell, Programme Director – QE Class, said: “To date, the power and propulsion alliance has not been late on one delivery, and not adversely affected the

ship build schedule, which is quite something on a project of this size and complexity.” Ben Ford, Programme Manager – QE Class added, “There are significant challenges ahead, but with the maturity of the sub-alliance and the partners working in the ‘best for project’ ethos we are well placed to deliver to time, quality and cost.” When complete, the QE class carriers will be the biggest and most powerful surface warships ever constructed in the UK.

Accurately placing rocks

The flexible fallpipe vessel Stornes is equipped with a range of Rolls-Royce systems to ensure accurate vessel positioning and rock placement for deepwater offshore projects.

D

utch Company Van Oord’s new flexible fallpipe vessel or FFPV, the Stornes went into service during the last quarter of 2011, following a christening at the Wilhelmina dock in Rotterdam, the Netherlands. The vessel was built at the Yantai CIMC Raffles Offshore yard in China. The Stornes is an ocean-going vessel that will be used mainly in the oil and gas industry for precision protection of pipelines and cables and has been designed to work in waters ranging from 300-1,200m deep. It is the third flexible fallpipe vessel in the Van Oord fleet, and with a deadweight of 27,000t is also the largest. It is 175m long with a 26m beam and 10.67m draught. Speed is 14.7knots. There is accommodation for up to 51 people. Rolls-Royce systems power and propel the vessel. Main propulsion is two Bergen B32:40L8P diesels rated at 4,000kW driving Kamewa CP propellers through 3000AGHC gears, which also drive two 2,200kW shaft alternators. Main propellers and flap rudders are designed for DP tracking and low noise. They work together with two Rolls-Royce ULC255CP retractable thrusters with electric drive and three TT2400 tunnel thrusters at the bow, each rated at 1,500kW to give the vessels its DP2 capability. All are controlled by the Rolls-Royce supplied automation and DP-system. Steering gear and deck machinery were also

part of the package. Fallpipe vessels are one of the indispensable tools for offshore exploitation and one of the essential pieces of equipment in the field of high-end offshore engineering. This special type of self-unloader is able to install rock close to fixed structures like rigs. Following commissioning, Stornes went to work on rock installation projects in the Norwegian sector of the North Sea. Likely future offshore projects are the installation of rock to secure oil and gas pipelines or installation of foundations for offshore wind farms. Other specific tasks that can be undertaken include free span correction, pipeline stabilisation, pipeline crossing and trench backfilling. Van Oord developed the flexible fallpipe technology in-house. Rocks are lowered through the fallpipe at a controlled rate and it is guided by a ROV unit attached to the end. The ROV is controlled from the ship and can be precisely positioned above the job ensuring accurate placement of the rocks at depth. The Stornes DP2-system tracks and maintains the ship’s position. The entry into service of the Stornes is part of Van Oord’s comprehensive investment programme for 2011-2015, totaling almost €1 billion. [AR]

ugs that perform ship assist duties have a varied operating profile. They have powerful engines that drive Rolls-Royce azimuth thrusters to provide high thrust and exceptional manoeuvrability. Full power is only required for relatively short periods, with the rest of the time spent in transit to the next job or waiting on the next order from the pilot on the ship being moved. Time is also spent moored up waiting for the next job. Therefore the search has been on for sometime on the most efficient way of delivering the right amount of power, at the right time, to minimise emissions. Rolls-Royce US 205 FP thrusters have been selected for the second of the Foss hybrid tugs, following the successful operation over the last two years of the first of the type, Carolyn Dorothy, at Long Beach and Los

Angeles. The latest is a conversion of the Campbell Foss. The original main engines have been replaced by smaller units plus gensets and a power management system. Lithiumion batteries are used instead of the lead acid batteries on Carolyn Dorothy to provide power for idling and other low power operations. Reductions in fuel consumption and emissions are the result. The RAmparts 2500W is the design used for two new compact tugs built for Rimorchiatori Reuniti for shipdocking operations in Genoa, Italy. Norvegia and Spagna are both equipped with two Rolls-Royce US 205 azimuth thrusters with fixed pitch propellers to deliver a bollard pull of 70 tonnes and are fitted with an off-ship fire-fighting system. The tug design is a new variation on the Robert Allan standard RAmparts 2500 design, with a wider beam of 11.25m on a length of 24.4m. The wheelhouse is placed further aft to allow the tugs to work under the bow flare of the vessels they are handling. Iskes Towing and Salvage is now operating its new tug Argus, in the port of Ijmuiden in the Netherlands. The 62.5 tonne bollard pull tug with a free running speed of 13.6 knots is designed and built by Damen, to its popular 28m ASD 2810 design. Two Rolls-Royce US 205 thrusters propel the tug, each driven by a 1,865kW diesel engine.

Also of Damen design, type ASD 3111, are the sister tugs Karloo and Kalarka, owned by Half Tide Marine in Australia. They are powered by two engines totaling 4,180kW and two Rolls-Royce US255 thrusters to give a bollard pull of about 69 tonnes. This design has been very successful, with some 20 ASD 3111 tugs now in operation. An updated design, the ASD 3112 is coming. Damen’s new offering will have Rolls-Royce thrusters for a 75 tonne bollard pull, and enhanced towing capability in rough seas. [RW] 1. The tug Norvegia

T

KBV 003 Amfitrite is equipped for chemical recovery at sea, as well as normal pollution control and emergency duties.

he new three-vessel fleet of advanced Coast Guard vessels that now operate from strategic bases on the Swedish coast are truly multipurpose. Designed by the Swedish Coast Guard in cooperation with the Swedish Defence Materiel Administration (FMV), their primary role is to maintain the nation’s emergency towing capability in territorial waters. However, they can also carry out border controls, pick up oil from the sea, fight fires at sea, control fishing and rescue distressed sailors. Normally stationed in Gothenburg, Karlskrona and Visby on the island of Gotland, two of the fleet are normally always at sea, operating throughout the Baltic and in the narrow waters that separate Denmark and Sweden. The vessels are 82m long, have a beam of 16m and a design draught of 5m. They have a displacement of 3,900t and a top speed of 16 knots. Designated KBV 001, 002 and 003, all were built by Damen at their yard in Galati, Romania. The first two vessels comply with DNV +1A1, TUG, LFL*, SF, OILREC, FIREFIGHTER1, EO, ICE-1A, DK(+), HA(+), AUT, ICS, NAUT-OSV, COMF V(2) C(2), CLEAN, RP. The third, KBV 003, is classed by GL and is equipped for chemical recovery at sea. The first vessel, KBV 001 Poseidon, joined the Swedish Coast Guard fleet of 40 ships in 2010. All are propelled by a pair of Rolls-Royce azimuth thrusters as part of the diesel-electric propulsion system. “As the Swedish Coast Guard has such a wide range of duties to perform,” explains Captain Christer Fjällstrōm,

UPDATES

Captain of KBV 001,” all our next generation ships are designed to be truly multipurpose. Although these Emergency Towing Vessels are the largest vessels in the fleet, they are no exception. As we do not have a large fleet, we have to ensure all vessels can deliver maximum effectiveness, no matter what the task is, with low operating costs.” A nation largely surrounded by sea with a coastline of 2,700 kilometres and territorial waters of more than 60,000 square kilometres, Sweden is the largest shoreline owner in the Baltic. The waters is a vital natural resource and protecting it is one of the key roles of the Swedish Coast Guard.

With large tankers now regularly loading near St. Petersburg and passing close by Sweden’s coast at the island of Gotland, continuing down to Denmark, and out into the North Sea, two major tanker accidents off the coasts of France and Spain illustrated well what could happen in the Baltic. The environmental consequences would be considerable. Therefore, the new vessels, which have 110t bollard pull, are equipped to catch and hold on station a fully loaded tanker of 150,000dwt, in conditions up to Force 10 wind conditions. The major challenge is to be able to undertake emergency towing in foul weather. Many scenarios are regularly practised to connect towlines to moving vessels with the deck-mounted cranes. Operating criteria for the new vessel therefore dictated optimum manoeuvrability and the best possible balance between high speed for open water patrolling, high bollard pull for towing and fuel efficient low speeds for search, rescue and oil recovery. The most recent addition to the fleet, KBV 003 Amfitrite, is also equipped for chemical recovery at sea. Additional onboard systems include accommodation and engine filtration systems to ensure safety of the vessel and crew, should it be necessary to operate in dangerous chemical cloud conditions. Normal crew complement is 13, but there is spacious accommodation for up to 44 to cope with exceptional circumstances. The computer network is extensive with an internet connection in each cabin.

Innovative propulsion To maintain optimum fuel efficiency with low emissions, the propulsion system is diesel-electric. Six generator sets provide a total power of 9,000kW. “Speeds of up to 10 knots can be maintained on a single engine,” says Hans-Erik Emanuelsson, Chief Engineer. “This delivers fuel consumption of around 350 l/hr, including the hotel load. Our intention is to operate all engines at high loads whenever possible, so the generators are of different sizes enabling the power to be closely matched to the required load.” The propulsion package incorporates a pair of Rolls-Royce US355 azimuth thrusters, which are directly coupled to electric motors, with three backup emergency steering systems. There are two thrusters in

the bow with one being fully-retractable. The remote control system for the machinery is arranged in the control room on deck 4. Azimuth thrusters were selected for their power for towing and manoeuvrability for oil recovery operations – a key part of the vessels’ duties as there are some 60 illegal discharges of oil annually from ships in Swedish waters, as well as accidents. Protecting the environment and the quick, effective removal of oil and chemical spills before they reach the land is the responsibility of the Swedish Coast Guard. The goal is to contain a spill within four hours and mobilise a large vessel to remove it within eight hours. “Oil recovery operations are nearly always conducted close to shore at speeds of around three knots,” says Emanualsson. “Therefore, precise manoeuvring is vital. We normally operate with two hydraulic systems running on the thrusters for greater responsiveness, and collecting booms at 90° from both sides of the vessel. However, on a recent deployment, we were able to try something new. Our thruster setup enabled us to move crab-like through the water at 40 degrees with just one boom deployed. The hull and boom acted as a funnel, enabling us to reach maximum oil in record time.” All vessels have a total of six heated tanks, or a total of 1,300m3, to store recovered oil.

Operational flexibility Two small high speed craft, one open and one closed, can be deployed from the side of the vessels at speed. They are used for investigation or rescue operations, and can be safely operated and recovered in all but the most severe conditions. The fire fighting system is equipped with two water cannons, capable of delivering water at 22,000 litre/min, with a reach of around 150m. The separate 18m3 foam system has the capacity to spray foam for around an hour. The selection of Rolls-Royce propulsors for these latest vessels continues the Swedish Coast Guard’s 30 years of experience in using Rolls-Royce propulsion products. [AR]

Helping harness the

power of the wind Rolls-Royce has been involved from the beginning with propulsion systems for offshore wind turbine installation vessels.

T

he first major contract was to supply systems and products for the pioneering installation jack-up vessel originally named Mayflower Resolution, now MPI Resolution operated by MPI Offshore, which is part of the Vroon Group. MPI Resolution was the first purpose-built wind turbine installation vessel (WTIV), designed to install foundations, towers and nacelles. It has been very successful, having been involved in the building of several offshore wind farms. Rolls-Royce provided complete integrated systems for MPI Resolution, combining its own products and third party equipment to provide the owner with a single-source supply. Included were the propulsion and manoeuvring thrusters – four 1.5MW US 205 azimuth thrusters at the stern and three 700kW CP tunnel thrusters at the bow, and the integrated control system. MPI is now putting into service two new WTIVs for which Rolls-Royce has provided both diesel electric power and propulsion systems. These vessels incorporate the knowledge gained from operating

www.rolls-royce.com

MPI Resolution under a variety of conditions. MPI Adventure, the first to be delivered, made the voyage from the build yard in China to Europe in 2011 and went straight to work. Operating out of Harwich, on the east coast of England where it is on its first contract, the MPI Adventure is in charge of installing foundations and wind turbines on the London Array offshore wind farm. The wind farm, the world’s largest, is located around 15km from the Kent and Essex coasts in the outer Thames estuary. Up to 341 turbines will be installed in an area of around 245km2. When complete, it will provide sufficient electricity for 750,000 homes. Sister ship, MPI Discovery, was delivered at the end of December 2011 and is now operating on the same project. MPI Adventure is a large self-propelled jack-up vessel, 138m long with a 40.8m beam, but drawing only 3.5m light. Six legs allow the vessel to operate in waters of up to 40m deep, with an ability to jack with 6,000t of cargo on board. The exact depth depends on the amount of sinkage of legs into the seabed and clearance needed between the sea surface and the underside of the jacked-up hull to avoid wave impact. Dynamic positioning to DP2 standard enables the vessel to be accurately located at the spot where a turbine is to be installed. The main crane is rated for 1,000t at 25m radius, with a hook height of 104m. The vessels also have accommodation for 112 people. Six Rolls-Royce Bergen C25:33L-8 diesel generator sets provide electrical power for all purposes. Three Rolls-Royce US 355 fixed pitch azimuth thrusters propel MPI Adventure, giving a transit speed of 12.5 knots, and are complemented by three TT 2200 DP tunnel bow thrusters. These new MPI-operated vessels are designed to transport, lift and install turbines and foundations efficiently, based on a good transit speed. They have the ability to move quickly from one installation location to the next, position accurately, jack up rapidly and begin installation work with minimum delay. The WTIVs can also remain on station, jacked-up, in severe weather conditions. [RW]

Power and speed

for effective wind farm support

Small craft known as wind farm support vessels are playing a vital role in building offshore wind farms and their subsequent maintenance. Rolls-Royce waterjets are proving the ideal means of providing the speed, economy and the power to safely ferry personnel, as well as transporting heavy equipment.

ith a growing number wind farms under construction and entering service, the development of the wind farm support vessel or WFSV is rapidly expanding. Boatbuilders and operators worldwide are competing to develop the best technology and techniques. Typically, the boats run at high

speed to and from the wind farm, but when at a wind turbine they must push hard against fender posts to hold themselves in position against wind, waves and currents while people transfer to the tower, or equipment is offloaded. Good manoeuvrability is vital in all circumstances, along with the highest efficiency and safety levels. “Waterjets have proved to be a

winning solution and operators are finding that Rolls-Royce waterjets offer an excellent combination of speed, static thrust and manoeuvrability,” says Andy Brett, UK Sales Manager. “Operator feedback from vessels in service is good, and many vessels now on order will be equipped with these units. Deliveries include both the smaller FF-series waterjets and the new Kamewa A3-series for the highest possible efficiency and durability.” In the case of Kamewa A3 series waterjets, the pump unit (impeller, impeller housing, stator and steering nozzle) are all made of stainless steel and are extremely durable in demanding applications. The pump performance has been improved in both the FF- and Kamewa A3-series, resulting in very high static thrust, exceptional cavitation margins and excellent performance over the whole speed range. All new models feature factory-mounted hydraulic valves and piping to reduce installation time and costs for the yard. The new compact control system makes operations easier and safer and is pre-calibrated, making the startup procedure extremely easy and quick. Engine RPM and clutch controls are integrated to the control system with several safety interlocks to avoid potentially hazardous situations. Inlet ducts are made of marine grade aluminium plate, allowing modular installation while custom tailoring for individual design needs can be provided, which further improves efficiency and optimises boat design and performance.

that control is intuitive, allowing the coxswain to focus on the safe transfer of people and materials. Waterjet propulsion allows operation in shallower waters than other solutions. CWind Asherah has the CTruk flexible pod system, which allows the operator to change the vessel’s layout to suit the requirement within a few hours. By moving the wheelhouse fore or aft, operators can optimise the vessel for different tasks, such as ferrying personnel or carrying service generators, cranes or survey gear. The vessel is currently operating for Dong Energy on the Walney array wind farm in the Irish sea. Alicat Workboats, based in Gt Yarmouth, builds aluminium catamarans for wind farm support using designs from Global Marine Design, Western Australia. They are currently building their third 20m WFSV. Rolls-Royce FF41 waterjets give a top speed of over 30 knots with Vector Stick controls for safe operation. East Coast Charters in the UK has built up a range of workboat services. Wind farm support is a growing part

of the business and to consolidate its position in the field, two new vessels are being added to its fleet. ECC Topaz is a 15m work catamaran specifically designed to transfer stores and personnel to wind turbines in shallow waters, but it can also undertake other tasks such as crew transfer for larger vessels. Blyth Workcats is the builder and this WFSV has two 410kW diesels driving Rolls-Royce FF41 waterjets with Vector Stick controls, giving a 25 knot service speed, with a maximum of 30 knots. ECC Topaz can carry up to three tonnes of cargo on deck and is certified for three crew and 12 passengers up to 60 miles from a safe haven.

Innovation in fishing vessel design

Adaptability is a key feature of the latest Rolls-Royce designs that combine low operating costs with low emissions.

1

NVC 368 Recently delivered is Prestfjord, a 65m long 15m beam NVC 368 factory trawler. The owner, Prestfjord AS, required an efficient stern trawler with full onboard factory that would have a low fuel consumption in all modes, a seakindly hull form and safe working conditions and good accommodation for the crew of up to 33. Therefore, the design has a low resistance hull form with bulbous bow and a hybrid propulsion system that provides fuel efficiency and minimum emissions in transit and when towing trawls at full power. The trawl deck occupies the length of the vessel and the processing area is on the main deck, with the 1,235 m3 freezing hold beneath. Prestfjord is built to DNV +1A1 Ice 1B, EO, Stern Trawler notation with ice class 1A* on the hull and meets the Norwegian Havfiske II requirements. Top speed is about 16 knots. The Bergen B32:40L9P main engine delivers 4,500kW and turns the 3.8m diameter CP propeller through an AGSC3000 reduction gear, which incorporates a PTO/PTI system with a 2,875kWe shaft generator. PTI power in diesel-electric mode is 1,200kW, and for maximum thrust, the total power can be boosted to 5,200kW. In addition to the 2,250kWe auxiliary genset, there is a 625kVA harbour/emergency genset.

A total of 20 Rolls-Royce AC electric winches of various sizes control all fishing operations. Both pelagic and bottom trawling can be undertaken with single or double trawls, and the trawl deck is laid out with four trawl tracks. Operating mainly in the North Atlantic, the main catch is expected to be cod, pollack, haddock, redfish and shrimps.

NVC 354 Two 77.5m long pelagic trawlers of the Rolls-Royce NVC 354 design will soon be fitted out at Larsnes Mek Verksted. Hull steelwork is now being constructed in Poland, and the vessels are scheduled for delivery at the middle and end of 2012 respectively. Although they are for two different owners, Eros and Kings Bay, the two trawlers will be identical in all major respects. The design features an innovative layout for the net handling system, which is located aft of the superstructure and under a shelter, giving the crew a safer and better working environment. The catch will be carried in refrigerated seawater tanks.

TRAWL CONTROL Rolls-Royce continues to expand its range of fishing vessel equipment. An example is the direct drive hydraulic winches and control systems for bottom trawling supplied for a vessel under construction in Turkey for Strand. These winches allow very sensitive dynamic control of the net, and now frequency controlled pumps can be run at speeds that minimise the use of energy without loss of responsiveness.

Another refinement in this vessel will be a further development of the Synchro RTX autotrawl system, which has been carried out in cooperation with the owner and trialled on Strand’s trawler Havstrand. “Better functioning, more functions available, are key words in this connection,” notes Havstrand’s skipper, Nils Kristian Skjong.

NVC 341 Abelone Møgster is a new NVC 341 fishing vessel that is remarkably adaptable. It can efficiently use purse seines, pelagic trawls and gillnets to catch different fferent species of fish ff in a number of locations at various times of year off ff the Norwegian coast. Rolls-Royce developed the new design to meet the special requirements of skipper and owner Harald Møgster from Austevoll. The vessel was built by Larsnes Mek Verksted. It is 43.1m long with a 12m beam, and is classed by DNV with an Ice C rating. The catch is held and transported alive in 500m3 refrigerated sea water tanks. Three fishing quotas are expected to provide all-year employment for Abelone Møgster Møgster, with only two weeks a year set aside for maintenance. Two crews of eight will man the vessel alternately. “A hybrid propulsion system was chosen to save fuel and reduce emissions in all operating modes,” says Monrad Hide, General Manager – fish. “When trawling, a combination of diesel mechanical and diesel electric drive makes maximum use of the available power. For purse seining, either diesel mechanical or diesel electric can be chosen. Gillnetting is carried out at a low to medium power, using diesel electric drive via the active front end converter and PTI motor. The fourth mode is transit and here, either diesel or diesel electric drive can be selected depending on the speed required.” The 1,325kW main engine drives through a reduction gearbox, which also carries an 800kW PTI motor and a 1,000kW shaft generator. Two 550kW diesel gensets can feed the PTI motor. Two 420kW tunnel thrusters are installed, one at the bow, the other at the stern. Abelone Møgster has two 25 tonne trawling/purse seining winches, a net drum, a net crane and a deck crane, two net haulers and two fish pumps for transferring the catch. The wheelhouse is laid out with multiple control stations, each for a particular type of fishing. Purse seine controls serving the winches and other deck machinery are located on the starboard side, while to port is the net handling system for gillnetting. Another station is concerned with trawling, carried out over the stern. [RW] [ 1. The factory trawler Prestfjord ord has a low resistance hull form and hybrid propulsion system.

DDG 1000 programme gathers momentum The contract to supply the United States Navy with Rolls-Royce gas turbine technology for its new generation of multi-mission destroyers, the all electric DDG 1000 Zumwalt-class, has advanced with installation of the first shipset of main power and auxiliary generators.

R

olls-Royce will supply two MT30 gas turbines and two RR4500 gas turbine generator sets for each of the three DDG 1000 destroyers on order. A number of key milestones have been achieved recently, including the installation of the first shipset of main power and auxiliary generators and the successful full power parallel operation of both gas turbine generator sets during simulated dynamic ship manoeuvring operations. The main generator, the Rolls-Royce MT30 marine gas turbine, and the auxiliary ship service generator, the Rolls-Royce MT5S (packaged as the RR4500 generator set), passed a series of rigorous Factory Acceptance Tests in April and May 2010. A single MT30 and RR4500 gas turbine generator set have been delivered to the US Navy’s Surface Warfare Center in Philadelphia for intensive land-based testing. For ship two, the Michael Monsoor, the first RR4500 was delivered in April with the second to follow in July. The two MT30 units will be delivered in August and September.

be the US Navy’s multi-mission destroyer, a forward-looking class designed to undertake a wide range of roles. The DDG 1000 is tailored for sustained operations in the littorals and land attack. It will provide independent forward presence and deterrence and support Special Operations forces, as an integral part of joint and combined expeditionary forces. Power density, manpower economy and advanced ship-board technology are essential to the Zumwalt class destroyer fulfilling its mission. Based around two sets of one MT30 and one RR4500, the Rolls-Royce gas turbine package provides the DDG 1000 with a highly versatile suite of power options. While the 36MW MT30s will provide the bulk of the power, the 4MW RR4500s will provide economy during light load conditions and peaking power when needed. As the DDG 1000 harnesses approximately ten times the electrical power of a DDG 51 destroyer, power reliability is paramount. The MT30, which is derived from the successful Trent family of aero engines, has a proven track record. Its selection for the DDG 1000 programme marks the first time a large gas turbine has been ordered by the US Navy for use as a generator set, providing electrical power for propulsion and on-board systems throughout the ship.

Andrew Marsh, President - Naval, said, “The Zumwalt class destroyer is a highly-advanced vessel, with demanding performance requirements. The MT30 is the world’s most powerful marine gas turbine and is well-suited to delivering the high-power demands of the latest naval ship designs.” The MT30 marine gas turbine is already at sea powering the US Navy’s Littoral Combat Ship USS Freedom. It has also been selected to power the Royal Navy’s QE class aircraft carriers (see page 40). Like the Zumwalt class, the UK carriers will benefit from integrated all-electric propulsion. Onboard the DDG 1000, the MT30s are the ship’s main turbine generators and, alongside the RR4500 auxiliary generator sets, are the power sources for the ship’s integrated power system. They provide power to propel the vessel and power for the ship’s hotel load (lighting, heating and ancillary functions) and other onboard advanced technologies, such as radar and weapons, and manages the power sources so the power requirements can be met when needed. The reliability and efficiency of the integrated power system, in combination with the ship control systems, means that manpower levels on board can be reduced compared to conventional ships, with less time spent on routine maintenance. In addition, the four-turbine set-up provides for reconfiguration under a range of operating conditions for greater survivability, reduced detectability and more secure communications connectivity. “The involvement of Rolls-Royce in the DDG 1000 programme does not end in the engine room,” says Peter Lapp, Programme Executive. “We are also responsible for the manufacture of the ship’s fixed-pitch propellers to stringent US Navy specifications. Two ship-sets have been cast in our Pascagoula, Mississippi foundry.” With the acquisition of Odim in 2010, the Rolls-Royce scope of supply for the class increased further and now includes the multi-function towed array handling system or MTAH, which controls the anti-submarine sonar and torpedo defence systems. The first ship set has already been assembled and integrated and is awaiting design verification testing. Construction of the first ship, the Zumwalt (DDG 1000) is more than 50 per cent complete at General Dynamics Bath Iron Works in Bath, Maine, and work on long lead items for the Michael Monsoor (DDG 1001) and the yet-to-be-named DDG 1002 has begun.

he Rolls-Royce marine training facility in Asia is now open for business at the new 65,000m2 Seletar complex in Singapore, which was formally opened by Rolls-Royce Chairman Sir Simon Robertson and the Prime Minister of Singapore, Lee Hsien Loong, in February. It is the result of an overall investment of S$700 million (US$500 million) and close cooperation between Rolls-Royce and the Singapore authorities in new research, training and aero engine production and test facilities in the region. It is a first for Rolls-Royce in that customers from across the various markets in which the company operates can be trained in the same location, enabling all attendees to benefit from purpose-built classrooms and extensive workshop facilities that includes a canteen and gym. Although a smaller version of the Ålesund marine training centre, Singapore can run most of the same courses. The latest technology, equipment and facilities are combined to help develop the talent pool of service engineers the company and its customers require, while promoting a culture of engineering excellence. With fleets growing and equipment becoming more complex, risks increasing and technical and environmental regulations becoming more demanding, the need for fully competent crews has never been greater. The marine section of the facility is equipped for customer training with two simulator domes that can be used for Icon DP systems, as well as Helicon X and 1

Towcon control systems training for anchor handling winches. They meet the need for greater realism and versatility by using a seamless spherical image of the working environment and allow trainees to practise manoeuvring and anchor handling operations in various sea states. Three smaller stand-alone DP manoeuvring stations enable up to five students to receive operator training at any one time. “The simulator domes are undoubtedly the main attraction for our customers in Asia. We are excited to have this new training resource available to us and the ability to offer enhanced knowledge and skills transfer to customers and partners in this fast-growing region,” said Gary Wieland, Senior VP, Services - Asia. The centre is also equipped to deliver a broad spectrum of learning across all Rolls-Royce business sectors - from IT to management and leadership, as well as technical skills.

expected to begin their new roles at Rolls-Royce in September. Hardware will change as new products enter service. Currently, the hardware includes a Canman waterjet control system, steering gear and controls, a waterjet module, deck machinery and engine sub-assemblies, plus a CP propeller hub and automation system switchboards, which are housed in two workshops. A range of classrooms will cater for small or larger groups.

Training in Europe The Rolls-Royce Training and Technology Centre in Ålesund, Norway is already in operation, with various courses in progress. It is located next to the campus of Ålesund University College, with the building’s grand opening planned for autumn. Regular courses for popular Rolls-Royce products and systems are a key part of the programme. Product training courses are run at four distinct levels: 0, 1, 2 and 3. The latest listing and joining instructions are regularly updated on the marine training pages of the Rolls-Royce website. Entry level (0) is standardised e-learning. It comprises product-based familiarisation modules, which currently cover 15 product groups and are the ideal starting point for any learning programme. Level 1 goes into more detail with courses available on most Rolls-Royce products. While some are purely equipment familiarisation and operation, others concentrate on the correct maintenance requirements, or both. Course duration and scope varies. For example, for CP propellers there is a four-day operator training course and a five-day maintenance course. For steering gears, there is a four-day maintenance course while for engine maintenance, it is a standard three-day course. Level 2 courses can be shipowner specific, where individual crew members need more advanced knowledge of particular products. The Royal Norwegian Navy, for example, books higher level maintenance training. Levels 2 and 3 are normally targeted at honing

the knowledge and skills of experienced Rolls-Royce service engineers. For individual requirements, tailored courses are developed on request to cater for specific customer needs. Bespoke courses on relevant ship equipment normally cover operation, trouble-shooting and maintenance. They can be run at the Rolls-Royce training centre of choice or on board a nominated vessel catering for the needs of a ship’s crew, typically a group of eight people or less. “As the Ålesund Centre currently caters solely for marine product training, a broader range of product hardware will be available than in Singapore,” says William Roberts, VP, Global Training and Service Engineer Development. “It is growing all the time, expanding as new equipment goes into service.” Equipment in the training hall currently includes operating steering gear with controls, two types of controllable pitch propeller with gearbox and pitch setting systems, tunnel thruster, steering system for large azimuth thrusters, a complete Azipull AZP85 thruster and a sectioned diesel engine. Power electric systems are represented with a complete switchboard for three generators with splittable bus and supply to consumers with fixed and variable frequency, typical of an offshore vessel installation. Anchor handling winch motors, a complete anchor and mooring windlass, seismic handling equipment and stainless steel and aluminium waterjets are scheduled to follow shortly. Simulators include a full-scale offshore vessel bridge with a 360 degree field of vision for ship handling, anchor handling and other offshore operations. Individual simulators in another room allow trainees to operate winches, cranes and other equipment. The Dynamic Positioning simulator and adjacent technical room have been expanded and installed in the new centre. Level 0, 1 and 2 DP courses are offered, covering familiarisation, basic and advanced operator training, maintenance and combined operation and technical courses, with Nautical Institute accreditation.

Playing a key role in vessel conversion Preparing a recently built 11,000dwt dock ship for a new role as a heavy-lift, deepwater oil exploration and offshore support vessel required a significant upgrade, including installation of a dynamic positioning and thruster package.

ork on converting the 172.5m long 25.4m beam 11,000dwt dock ship owned by Harren and Partner (the former Combi Dock IV) into the heavy-lift, deep-water oil exploration and offshore support vessel OIG Giant II, got underway in August 2011 at Lloyd Werft, Bremerhaven. The vessel is the second ship in the Offshore Installation Groups (OIG) planned fleet of six offshore support vessels. Combi Dock IV was one of a series of four heavy lift dock ship sisters built between 2007 and 2010. One has already been converted into OIG Giant I. The work undertaken was wide-ranging and used experience gained from the earlier conversion of the first vessel. At the heart of the work was the installation of a Rolls-Royce DP2 system and thruster package.

Dynamic positioning with power and manoeuvrability New to the ship and consistent with its specialist new tasks is the Rolls-Royce DP2 equipment package. It includes a DP2 dynamic positioning system, with sensors and reference system, Poscon joystick, Helicon X3 remote controls and five new thrusters. The complete system, including the electric motors for the five thrusters, was designed and supplied within the relatively short five-month delivery time frame, to meet the conversion schedule, and was managed by the Rolls-Royce service team in Ulsteinvik. To get the required increase in propulsion power into the hull required the relocation and enlarging of the ship’s forward bow thruster, which was replaced by a TT2650 tunnel thruster, together with a TCNC92 combined swing-up azimuth thruster that can also operate as a tunnel thruster when retracted for operational flexibility. To provide optimum manoeuvrability and due to the limited space below deck, a TCNS92 swing-up azimuth thruster, rated at 2MW with a 2.2m diameter propeller, was installed in the middle of the ship. A hull module suitable for a TCNS92 thruster was prepared by the yard for the

with an active heave compensation system. They now have a combined safe working load of 500mt for subsea installations to a depth of 2,500m. A 7.8m x 7.4m moonpool on the starboard side of the loading bay enables divers and equipment to be lowered into the water. OIG Giant II was also fitted with a submersible and tiltable open stern ramp for floating in or out, a helipad and an additional seven-deck accommodation extension to the forward superstructure to house a further 86 personnel. Six more generators were also installed to ensure that the vessel’s new capacities have the power required.

installation of a third unit, should more power be required in the future. Two TT2400 tunnel thrusters with CP propellers were installed in the stern. “We designed the system to meet the specified operational profile of the vessel,” says Stein Arve Molnes, Sales Manager – upgrading/overhaul. “As our DP systems are designed to work with our thrusters, we were able to provide a complete system and quote a single package price. This reduced the number of suppliers involved and provided the confidence that the system would perform as designed. Courses for crew training were run at the Ålesund Training Centre.” The conversion included a range of other work, undertaken by the yard. The ship’s two forward, heavy-lift cranes were significantly lengthened to enable them to reach as far and as high as possible, and were equipped

The vessel’s first job was the transport and installation of three turbines for a tidal power station off Orkney in the North Sea during late 2011. The work was performed with remarkable accuracy in 30 knot side winds with a 5 knot current from the stern - a suitable demonstration of the DP systems performance. OIG Giant II is the second ship in the planned threevessel fleet of Singapore-based Offshore Installation Group (OIG). The recently founded company, a joint venture between Harren & Partner and Goldman Sachs Capital Partners, serves the oil and gas industry with large specialist ships. The vessels are equipped for a variety of installation work far out to sea and can operate at depths of up to 2,500m. The large deck area means they are able to take everything on board at the start of a project, so the support of other heavy lift vessels to transport equipment is not required, saving time and money.

Rapid response for emergency maintenance Selecting underwater intervention services offers enhanced flexibility in minimising vessel downtime, particularly when urgent unplanned maintenance is required.

R

olls-Royce added turnkey underwater intervention to its marine services portfolio over three years ago and has since developed a number of innovative repair methods where drydocking is not required. When a customer contacts Rolls-Royce with a request for underwater intervention, the requirement is assessed against a range of suitable solutions to determine the best approach relative to the current operating conditions and location. Once the solution is agreed with the customer, Rolls-Royce mobilises service engineers, the diving partner and all necessary equipment to the vessel or quayside. Rolls-Royce acts as the single point of contact throughout, providing seamless project planning, management and execution of the work. A successful underwater intervention project was recently undertaken on a Rolls-Royce TCNS92 azimuth thruster installed on a semi-submersible rig operating off the coast of Angra dos Reis near Rio de Janeiro, Brazil. The customer, Ensco, reported that the thruster on the ENSCO 6000 rig was leaking at pitch control level and required an emergency repair. With no time to wait for a suitable dry dock to become available to enable the repair to be carried out, underwater intervention provided a safe and vital alternative.

A team from the Rolls-Royce service centre in Brazil and propulsion product centre in Norway worked in collaboration with the diving partner, Subsea Solutions Alliance, and Ensco personnel to plan the work. The agreed solution was an underwater repair of the oil distribution box with a team comprising one project manager, one service engineer and three divers working over two days to complete the repair. “Underwater intervention offers our customers a time-sensitive service that enables critical repairs to be performed directly at the rig’s location”, said Peter Redpath, VP Sales in the Gulf of Mexico. “This efficient operation was concluded within the allotted time-scale and the rig was able to return to service with minimal downtime.” Ensco, with a fleet of seven drillships, 20 semi-submersible rigs and 49 jackups, recognised the value of employing Rolls-Royce to manage this turnkey project. “We are pleased the intervention work was conducted safely, on time and with care to prevent spills and environmental impacts,” said Gilles Luca, Ensco Vice President, Brazil. Amanda Martin, Ensco’s Director of Supply Chain, Western Hemisphere, added, “Rolls-Royce has been a

proactive supplier partner, working with Ensco stakeholders to improve the communications and planning between our organisations. We appreciate the commitment to customer satisfaction, which has resulted in continuously improving supply and service efficiencies for our fleet.” Following this success, Ensco has selected Rolls-Royce to undertake the removal and re-installation of six UUC 455 azimuth thrusters installed on the ENSCO DS-6 drillship. Rolls-Royce service engineers and product centre personnel from Finland will work closely with their counterparts in Singapore to perform the operation, needed to accommodate the massive ship’s hull in the shipyard prior to the drillship commencing a new charter later this year.

DFDS ferry trio upgraded with

Promas Lite

Improving propulsive efficiency is key to reducing fuel burn and emissions, and the number of vessels successfully upgraded continues to grow. Three ferries operating on the English Channel crossing are the latest to benefit.

T

hree more DFDS Seaways ferries have been upgraded with the Rolls-Royce Promas Lite system to maximise their propulsive efficiency, reducing fuel consumption and emissions. Dover, Dunkerque and Delft Seaways serve on the Dover-Dunkerque route across the English Channel. The three sister ships were originally designed for a service speed of 26.5 knots and had Kamewa propellers optimised for that speed. The requirements for the Channel route is a lower service speed of 18-19.5 knots, with a little more speed available to recover delays and power for responsive manoeuvring in port. This has resulted in not only poor operating efficiency, but also enhanced vibration levels during manoeuvring. The ferries have twin screws and two engines per shaft, and normal sailing on the route can be maintained on one engine per shaft, with more power available if required. The Promas Lite system was selected as it integrates the propeller

and rudder into a single system to maximise hydrodynamic performance over a conventional propeller reblading. The customised design was developed at the Rolls-Royce facility in Kristinehamn, Sweden. New propeller blades were bolted onto the original hub and a special hubcap fitted to the propeller, which streamlines the flow onto a bulb that was fabricated and welded onto the existing rudder. This effectively increases propeller thrust, as previously wasted energy is recovered from the flow, and also reduces drag. The hubcap is mounted outside of the propeller hub and acts purely as a hydrodynamic fairing, keeping cost and technical complexity to a minimum. The settings of the existing control combinator were revised to ensure that optimal engine load and propeller pitch was combined for maximum efficiency. “Generally, we predict a Promas Lite installation on this type of vessel, which is also operating significantly off its original design speed, should provide an efficiency improvement in the region of 10 to 15 per cent at transit speed,” says Klas Nygren, Service Sales Manager, propellers and waterjets. “Depending on the time spent at transit speed versus manoeuvring in port, the overall efficiency improvements will obviously be reduced, but still represent a significant reduction in fuel burn and emissions. As our systems are performance matched, a typical side benefit is reduced propeller-induced

vibration, which enhances the overall passenger experience.” The turnkey upgrading of all three ferries was undertaken during the first quarter of 2012 at the Arno Dunkerque yard in France. The first and second installations were delivered on time, and the third two days ahead of schedule. These efficiency improvements will contribute to the DFDS goal of reducing CO2 emissions by 10 per cent over a five year period. [AR]
