Floating Fenders Yokohama Floating Fenders – Pneumatic 50/80 Yokohama began manufacturing floating pneumatic fenders in 1958. Since then, more than 60,000 Yokohama fenders have been supplied into ship-to-quay and ship-to-ship applications worldwide. Put quite simply, over the course of the past half-century more people have put their faith in Yokohama fenders than in any other brand of pneumatic fender. And that faith has been justified by the durability and longevity of the fenders – providing an outstanding return on the investment which their owners have made in them. ISO 17357 is now firmly established within the marine industry as the international standard for the manufacture, testing and performance of pneumatic rubber fenders. Over the years Fendercare Marine has discovered that although other manufacturers may be claiming full compliance to ISO 17357, it can be demonstrated that in certain cases irregularities have been found where fenders that have been supplied as compliant do not in fact comply with the standard in one or more of the following criteria: incomplete material tests hydrostatic pressure test wrongly conducted or failed incorrect evaluation of angular and durability tests incorrect reinforcement material used rubber specifications not meeting ISO 17357 requirements certificates out of date or non-existent Drawings and picture references are for illustration purposes only.

Yokohama can demonstrate compliance to PIANC 2002 for floating pneumatic fenders. Further information can be supplied on request.
Advantages Safe for excess load The reaction force of a floating pneumatic fender does not increase sharply even under excess load. Therefore, these fenders perform extremely well under such conditions and, as a result, protect ships and mooring facilities. No deterioration or variation in performance Because pneumatic fenders use the compressive elasticity of air, there is no performance deterioration due to fatigue. The performance of these fenders remains unchanged at extremely low temperatures, even below -50°C. Safety and reliability Yokohama pneumatic rubber fenders are constructed using several layers of strong tyre cord and are therefore extremely resistant to pressure and cutting. The larger sizes (2.5m dia upward) are fitted with a safety valve to prevent accidents in the event of over compression.
Construction The fender body is constructed of an inner rubber layer, reinforcing cord layers and an outer rubber layer. All of these layers are vulcanised together and then proven by hydraulic pressure test. The outer skin rubber compound is designed and manufactured to be able to withstand both strenuous use including abrasion during adverse weather conditions whilst protecting the cord layers and inner rubber. The synthetic tyre cord layers are arranged at optimum angles designed to distribute load and stress evenly. The inner rubber compound is designed to be completely airtight, utilising a compound equivalent to that of an inner tube of a car tyre. To provide maximum strength and safety, the outer skin of a hydro-pneumatic fender is thicker than a normal surface fender. Outer rubber

Simple and low cost installation The weight of the fender is supported by the water on which it floats. Fenders can, therefore, be moored simply by means of a guy rope or chain at minimal cost. They can be removed easily to another position when not in use and transferred to alternative mooring points as required.
Chain and tyre net In the vast majority of cases, a chain and tyre net will be fitted to a pneumatic fender to protect the body from damage by sharp objects or via the absorption of sheer loads during berthing. The better the net, the more protection it will offer. From experience in using these fenders ourselves, we have developed a unique high protection net system which offers more protection to the body of the fender than any other net available in the market today – thereby potentially extending the life of the fender.

We have the widest possible experience of the varying needs of a protective net and offer a range to meet all needs: lightweight nets to meet ship’s crane and davit limitations heavy duty nets to cope with harsh sea conditions and high snatch loads double nets to offer stand-off options non-marking tyre nets for navy and cruise ship applications rope nets for ultra lightweight applications stainless steel nets for non-magnetic requirements
All Fendercare Marine nets are designed with ease of maintenance in mind. The net is built in sections so it remains easy and cost effective to repair, should a specific area of the net sustain damage.
Identification Each fender has the following markings: identification requirements international standard number and applicable year size (diameter and length) initial internal pressure date of manufacture name of manufacturer individual serial number type of reinforcement layer
RFID tagging system Radio Frequency Identification (RFID) is now fitted to all Yokohama fenders. A tag is buried in both ends of the fender enabling easy reading however they are positioned. This RFID tag was introduced so you can identify the individual fender should the standard markings become unreadable. It will also assist in the maintenance of records and inventories over the long-term. Fendercare Marine are able to supply the RFID Tagging Reader as an optional extra. This reader can read all RFID tags mounted on fenders manufactured to this specification. Fendercare Marine also maintains a database of all Yokohama fenders that are sold worldwide and can therefore assist in returning fenders to their rightful owners, should they become lost or stolen.
Certification Each fender is supplied with a certificate, detailing the following: material for rubber and fitting metal satisfactory results of tests record of compression test dimension and weight record of serial number and RFID tag number

Hippo Floating Foam Fenders Our in-house Hippo brand, manufactured in the UK, is one of the world’s leading designers and manufacturers of floating foam fenders. The use of memory foams for the fender core, which have high compressive strengths, results in an ability to absorb a great deal of energy during operation. This is complemented by low reaction forces, making berthing operations easier – especially in difficult conditions. Users also gain peace of mind from knowing that the closed cell structure of the foams used by Hippo means that these fenders are virtually unsinkable and will keep functioning – even if damaged beyond viable repair. Although fitted as standard with highly durable nylon reinforcement to the outer skin, we are now uniquely able to offer Kevlar™ reinforcement systems to those customers seeking the highest possible level of protection from in-service damage and therefore, the best possible return on their investment. One other feature worthy of mention is the simple yet unique internal structure of the fenders which allows the shear loads to be absorbed by a through-chain arrangement terminating in end-shackles rather than the body of the fender itself. This has been engineered so that in the event of overload, any damaged components of this system can be replaced in isolation – as opposed to other foam fenders where the end-fittings form an integral part of the internal workings of the fender and which, if damaged by shear forces, can lead to the fender being written off.
Key features of Hippo fenders High energy absorption/low reaction force Virtually unsinkable Simple, effective internal engineering Low maintenance costs Easy installation Non-marking PU elastomer skin Optional Kevlar™ reinforcement Available with best in class Fendercare Marine chain and tyre nets Standard range supplemented by bespoke design service
Typically Hippo floating fenders would be supplied as cylindrical units, but due to our flexible manufacturing processes and our commitment to offering best possible assistance to our customers, we have also supplied spherical, rectangular and cog-type fenders.

Hippo Floating Donut Fenders Hippo Marine has been manufacturing and supplying donut fenders for well over a decade. Donut fenders are, very simply, a donut shaped type of foam filled floating fender which are designed to slip over a stationary monopile. They have also been supplied into other applications, such as protecting jack-up legs. The principle of such fenders is that they float up and down with the tide therefore ensuring optimum protection at all times. They are also designed to freely rotate around the pile to allow vessels to slide along them into the required position – making them ideal for applications such as lock and dry dock entrances and protecting bridge supports.
Main advantages of donut fenders igh energy absorption/low reaction force compared to bucking type H rubber fender Low shear forces as the fender rotates, combined with low-friction skin Self-adjusts with the water level to always be in the correct position Quick and easy to install – simply slipped over a pile Low ongoing maintenance requirements

Construction The fender body is constructed from a rubber inner core with a non magnetic metal mouthpiece at both ends. A grey rubber outer skin with a minimum of two plies of tyre cord layers, also coated with rubber, protects the inner core. The fenders can therefore be used on mine counter-measure vessels.

Fendering
Floating Fenders A PT1/8 air valve is fitted at the end of the fender to allow access for inflation whilst ensuring maximum protection from damage during normal use.
Application Vessels carry the fenders onboard with them at all times, for use both at home, at sea and in foreign ports as utility fenders. The fenders are used primarily for two applications – ship-to-quay and ship-to-ship. For ship-to-quay application the fenders are used to berth a vessel alongside a quay or wharf. For ship-to-ship application the fenders are used to berth or moor two vessels side by side (double-banking) in port or at sea. There are three main configurations for fender grouping when in use:
Three single eye arrangement
Three double eye arrangement
One double eye/two single eye arrangement
Mooring positions of the fender groups on the ship should keep the ship separated and stable at the same distance from the quay or another ship all along the parallel mid-body. Berthing against a quay or a stable ship moored in port is straightforward but the following should be considered when confirming fender size: (1) the approaching ship’s docking speed, (2) approaching angle, (3) hull shape, (4) protrusion from ship and (5) equipment fitted on the hull. It should be carefully noted that required stand-off distance is an important variable to consider when berthing. For example, if a vessel is light in weight but requires a stand-off of 2 metres (due to large flare or parts/equipment standing proud of the hull such as a stabiliser) then larger fenders would be required. Quay, or another vessel of similar size in more stable or moored condition (can also carry fenders on this side)
Vessel carrying the fenders
3-5 Groups of 3 fenders configuration in front, mid and rear positions of the vessel. The number of groups depends on vessel parallel mid body length
