A practical approach to SEEMP

Why SEEMP?

The Insatech SEEMP system

• Ticket to trade

• Information display onboard in realtime

• Decision support

• Aid in on-board decision making

• Optimise operation

• Only useful information is sent to HQ

• Creates added value for shipowners if vessel performs above average

• Ensures responses by use of ”guidance system” for vessel operations

Data Aquisition System on board

What is SEEMP?

IMO Implementation guidelines

SEEMP will become mandatory for all vessels at their first renewal or intermediary survey after 1 January 2013. (IMO MEPC 62, July 2011) • Under the proposed amendments to MARPOL Annex 6, Regulation 22, all ships must have an International Energy Efficiency Certificate (IEEC). • The IEEC requires, amongst other things, the presence of a SEEMP on board. • The SEEMP may form part of the ships Safety Management System (SMS).

Planning

Why SEEMP? • Implement a plan to improve the energy efficiency of a ships operation. (Part of a broader corporate energy management policy.) • Fuel cost is the largest cost element for shipping companies. 35-65% of operational costs depending on type of vessel. • Energy efficiency improvements can give cost savings of 5-15% and bring down Greenhouse emissions • Port fees based on environmental impact • Global players are demanding emission data (DHL, IKEA ...)

Who should implement SEEMP? • SEEMP is a ship specific plan to be developed by the shipowner, operator or charterer • The plan should be adjusted for the characteristics of individual companies and ships • SEEMP is a management tool and should limit the onboard administrative burden

2

• Current status of ship energy usage and the expected improvement of ship energy efficiency is determined. Establish a baseline! • Define and prioritize initiatives • Both ship internal processes and operational aspects should be covered. (Speed optimization, weather routing, hull maintenance, “just in time” etc.)

Identify

The Insatech approach to developing an efficient SEEMP SEEMP planning

• Keep records to assist in self evaluation

• Start with ”the low hanging fruit” the largest energy consumers on board

Booster pump

Flowmeter

• One approach is to use design documents or sea trial data if these have the necessary values

Evaluation

The practical baseline • Start with ”the low hanging fruit” the largest energy consumers on board. • Evaluate the quality of the information currently available on board.

Defining a good baseline

• Define an operational profile including Routing (plan and weather), Trim, cargo operations, autopilot use etc.

Heater

Single flowmeter system

HFO/MDO

• The burden on ships staff should be minimized • Progress of different improvement initiatives should regularly be followed up • Establishing well defined self-evaluation periods will give an understanding of cause and effect that will improve the efficiency of future investments. • An understanding of the overall characteristics of the ships operation will result in a better prioritizing of future stages of the management plan. • Self-evaluation and improvement • Evaluate the effectiveness of the implemented improvements • Set new goals and implement the next cycle of the plan. • SEEMP is not a static tool, but a continuous “work in progress”

Feeder pump

• Minimize crew involvement i.e. automate data aquisition and transfer

• Main energy consumers are: Main engine(s), electrical production and boilers

ViscoSense sensor

Mixing tank

Flowmeter

• Define the requirements for data aquisition, ensuring the system is expandable to handle all future requirements • Define how data will be transferred from the vessel, data safety requirements, storage and use at HQ

• Ensure benefit realization! (Requires a well established baseline with repeatable measurements) • Continuous and consistent data collection is the foundation for monitoring. • Performance monitoring that is standardized for the whole fleet is recommended. (EEOI) • A good monitoring system should track the benefits of each prioritised initiative

HFO/MDO

• Establishing a good and repeatable baseline is the key for implementation of SEEMP

• Define how the prioritized initiatives are to be implemented on each ship • Define the owner(s) of each measure • Define each project with a start and end date

Challenges to achieve repeatable fuel flow measurements

Data Aquisition

KPI values in realtime

Important features for data retrieval

• Use industrial grade systems that can handle the tough environment found on board

Built in report functions for on board use – influences behaviour

• Automatic system sends encrypted Noon Reports. (Push) • Automatic archiving – based on vessel and time/data stamp • Conversion to ”open format” and use in standard systems e.g. SQL databases

• Challenges: Vibration, quality of power supply, ambient atmosphere, expandability • Data collection speeds vary greatly, e.g. wave monitoring needs higher speed than COG • Interconnectivity to other systems e.g. navigation systems (NMEA) • Access to reports/KPI’s on board is a must

• Correct sizing of flowmeters • Calibration of temperature sensors • Manual input of the correct base density in the flowcomputer! • Not practical!

• Data compression and encryption to save costs

Advantages of the Insatech SEEMP Data Aquisition system

The optimal solution for measuring fuel flow

• Open Industrial system for ease of integration to exsisting systems • Built in Report functions • Encrypted data – Read only format.

Influence decisions on board

• Strong mathematical functions allow real time calculated values to be displayed e.g. Tons fuel/NM/ton displacement • Such values can be used to create new baselines for performance if wind and sea state values are compensated.

Minimising data • Even though all values are read e.g. every second, we can minimise data amounts.

Event based logging

t ge N e w Tar

• Use a Coriolis massflowmeter that can handle the vibrations and flow pulsations . (Not all designs can) • Pipe stress is a challenge for some types. • Uncertainty of a Rotamass system is: 0,1% of actual value • Density output can be monitored for alarming of ”capuccino effect” in fuels

• Minimises necessary data volumes without losing crucial details. Event based detailing

• No need to send data to HQ, make reports and send them out again.

e ur

Lowering the uncertainty of flow measurements

• The built in report functions enable us to make locally viewable reports that can be designed to have a positive influence on crew behaviour and decision making.

De fin

• Most vessels are equiped with volumetric flowmeters – typically a sliding vane meter • These have a full scale accuracy • Correct sizing is important. • Volumetric flowmeters need to compensate for density variations as we require a readout in kgs or tons • Base density can vary up to 100 kg/m3! This is 10%

Evaluate Coriolis flowmeters accurately measures mass flow and density. 4

Key features of the Insatech SEEMP System

• We reccomend the use of KPI’s as the base for easy comparison of performance.

• We suggest the use of predefined speed tests where the following factors are included:

• Voyage Performance

• Use KPI’s to influence on board behaviour as well as for monitoring performance degradation.

– Speed and SOG (define current/wind influence)

• Energy Consumers

• Easy acess to KPI’s with a strong graphic presentation, and warning/alarms can ensure due diligence on board

– Wind speed, True and Relative (wind resistance)

• Industrial proven in use components • Data transfer to shore minimised • Real time KPI’s on board • Built in guidance on board requiring crew acknowledgement ensures actions are taken. If not the responsible crewmember can be found

KPI main groups • Main engine performance (g/bkWh) • Aux. engine performance (g/bkWh) • Vessel performance: • Thrust/displacement (if available) • Fuel consumption (kg/NM/ton)

– Displacement (wetted surface area and wind exposure) – Sea state/wave height (WSA and WR) – Rudder activity – Defined minimum run times to ensure repeatability

Continous improvement is necessary • Define/understand -> Measure-> Action/Change-> Evaluate -> New Target

• Electrical power consumption per area

• On board tools using real time consumption and performance figures against targets

• Vessel Trim especially in Ballast mode

• ”Drill down” functionality for main units or consumers.

Overview of all relevant KPI’s giving decision support

• Power generation vs actual use and safety factors

• Buffer time, idle time • Speed / RPM divation • Propeller & Hull maintenance • Weather effect • Lube oil consumption • Fuel statistics / Bunker • Fuel alerts • Anti-fouling evaluation • Speed / consumption prediction, speed optimization • Engine efficiency, engine utilization and optimizing • Energy profiles • Voyage optimization • Operational profiles • Warnings and triggers • Environmental statistics & EEOI

• EEOI (Energy Efficiency Operational Indicator) tons CO2 / transport work – see IMO guideline

• Main & Aux Engine • Vessel Performance • Fuel Management • Environmental • Operations • Guidance / Warning • Boiler(’s) and Incinerator • Vessel KPI’s • Trends & Tests • Administration Setup

• For crew to take responsibility, it is important that the values displayed are credible

• Costs • Bunker composition

• Less scatter and a better aid in decision making

• Fuel costs and quality

• Advisory messages e.g. best power plant configuration at the given operating conditions

• Selected fuel

• Data accessible on board, HQ and ”home” • Ranking system for the fleet – competition = motivation

Credible measurements = Better decisions

• Take ”Raw” values” and normalise them for display. (Speed/ Power curve to be normalised for displacement, wind speed/ direction and wave action)

• EPI
