YOKOHAMA FENDERS
FenderCare is an international maritime company comprising operating and regional companies with numerous worldwide support bases. Established in 1988, it has seen substantial growth and diversification.
FenderCare Limited
FenderCare is renowned for its specialisation as a distributor and operator of the Yokohama pneumatic fender, offering sales, rental, lease and refurbishment. The construction of the Yokohama fender is the key to its outstanding performance, durability and its factor of safety. Yokohama pneumatic fenders provide superb protection and are also one of the most flexible fendering products available.
Fenders – Sale and Hire
A 24-hour worldwide service is provided as both new and used fenders are stocked at its worldwide bases. Fender applications include short-term port calls or one-off berthings; interim fendering during construction or maintenance work; transfer of cargoes at sea; buoyancy aids; providing vessel stand-off or double berthing requirements.
Chain & Tyre Nets
The chain & tyre net design protects the fender body, whilst its quality build gives it longevity. Zinc-coated metal components protect against corrosion, whilst the simplicity of its design allows for easy maintenance.
Refurbishment
FenderCare is one of only a few Yokohama approved repair service providers, giving peace of mind and security for your investment. Our refurbishment service consists of:
- Fender body/end checking and testing (assess for repair)
- Safety valve testing and re-calibrating/replacement (if necessary)
- Net/component checking (and replacement, if necessary)
Worldwide Bases
Stock is held for sale or hire at bases located in the UK, Europe, the Middle East, SE Asia and West Africa.
Fixed Fendering
FenderCare is also a major supplier of fixed fender solutions for wharves, docks and jetties, as well as tugs, oilfield support vessels and many other craft.
Ship-to-Ship Hose
Incorporating the experience and knowledge of many years in the ship-to-ship transfer business, FenderCare offers purpose-designed anti-static hoses of different types for various cargo transfers.
Hose Testing
A self-contained transfer hose testing facility is available in the UK that is easily transported to site. All makes of hose can be tested by experienced staff to manufacturers’ specifications.
YOKOHAMA FLOATING FENDERS PNEUMATIC 50 & 80
Yokohama are the market leaders and innovators in floating fenders and have been manufacturing fenders for over 40 years. About 60,000 of these fenders have been delivered to date, with new pplications continuously expanding their use in ship-to-ship service and at large-scale port facilities. During the last 15 years, FenderCare, as sole authorised Yokohama distributor for the UK, has maintained and refurbished fenders for clients worldwide. A large stock of the full range of sizes is held at our bases which cover over 25 countries.
All Yokohama floating pneumatic fenders are ISO 17357 compliant. Our shipto- ship transfer division (FenderCare Marine) only uses Yokohama pneumatic fenders in their operations, due to their proven track record and their compliance with all industry standards.
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 utilise the compressive elasticity of air, performance deterioration due to fatigue is completely absent. The performance of these fenders remains unchanged at extremely low temperatures, even below -50°C.
Safety 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 (2.5 m 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 three layers are bonded together by a combination of heat and pressure over a period of time in a vulcanising oven. Once completed, the fenders are pressure tested before release.
To provide maximum strength and safety, the outer skin of a submarine fender is thicker than a normal surface fender.
The outer skin rubber compound is designed and manufactured to be able to withstand both strenuous use and adverse weather conditions whilst protecting the cord layers and inner rubber. The cord layers are arranged at optimum angles designed to distr
Testing and materials
Rubber
The cover rubber is a compound of natural and synthetic rubber. The physical properties of the compound are as shown in the tables below, for the outer and inner rubber respectively. All fenders are tested in accordance with both ASTM and JIS standards.

Simple and low cost installation
The weight of the fender is supported by the water on which it floats. Therefore, the fender can be moored simply by means of a guy rope or chain at minimal cost. It can be removed easily to another quay or jetty when not in use or transferred to alternative mooring points as required.

The chain net weights quoted in the tables above are for standard designs and stocked sizes. If you have any special requirements regarding weight, stand-off etc., we are able to make nets that will satisfy most bespoke specifications.
CHAIN AND TYRE NET
Almost all floating fenders should be protected by a chain and tyre net.
The purpose of the chain and tyre net is to protect the fender body from damage by sharp objects or protrusions such as rough faced quay walls, to distribute sheer forces along the length of the chain net and to prevent the fender body from having to absorb them.
FenderCare is a provider of floating fenders and also an operator. As an operator we have the widest possible experience of the varying needs of a protective net and can offer the following:
- 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 both Navy and cruise type applications
- Rope nets for ultra lightweight applications
- Stainless steel nets for non magnetic requirements
All FenderCare nets are designed with ease of maintenance in mind. The net is built segmentally so it remains both easy and cost effective to repair should a specific area of the net sustain damage.
We maintain full service centres in the UK, Middle East and SE Asia in addition to which, FenderCare has it’s own team of engineers and fitters who can travel anywhere in the world to maintain and repair Yokohama fenders.
