Inflatable floating pneumatic rubber fender


1. Introduction
Evergreen Maritime is the world leading manufacturer of pneumatic rubber fender, and China unique manufacturer complys with ISo17357:2014. His products are certificated by CCS, ABS, LR, BV, SGS, etc.

High pressure floating pneumatic rubber fender is a leading anti-collision device for marine application in the world today. It is made of synthetic cord reinforced rubber sheet with compressed air inside to enable it to flaot on the water and work as a shock absorber when ship to ship transfer operations and ship to quay berthing and mooring operations. The first pneuamtic rubber fender was developed in 1985 based on the technology for auto mobile tires and rubber aircraft fuel tanks by YOKOHAMA RUBBER COMPANY.

Pneumatic fenders have the advantages of massive energy absorption with low unit surface pressure acted upon the ship. So pneumatic fender has become an ideal ship protection medium used extensively by large tankers, LPG vessels,ocean platforms, bulk carriers and floating structures, large docks, harbor and wharfs


Evergreen Maritime ensures that all its pneumatic rubber fenders fully company with all requirements of ISO17357:2014

Evergreen Maritime commites to manufacture and provide the high quality pneuamatic rubber fenders for STS, STQ operation.

In order to produce the qualified and famous China Brand of pneumatic fenders, Evergreen Maritime invested the advanced production and test equipments, and invited the foreign experienced engineers of pnematic fenders, which ensure all Evergreen Maritime pneumatic fenders are manufactured comply with ISO17357:2014. 

Therefore, Evergreen Maritime is the unique manufacturer of ISO17357 qualified pneumatic fender in China

2. Construction

Floating pneumatic rubber fender, whose basic body construction consists of outer rubber layers, synthetic-cord-reinforced rubber layers and inner rubber layers, are kind of cylindrical airbags with hemispeherical heads at both ends. All of these are vulcanized together and then compress air inside to enable it to float on the water. So pneumatic fender has become an ideal ship protection medium used extensively by large tankers.,LPG vessels, ocean platforms, bulk carriers and floating structures, large docks, harbor and wharfs.

2.1 Outer rubber
The outer rubber layers that covers the outside of fender protects the cord layers and the inner rubber from abrasion and other external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage. Standard color is black, but other colors such as grey and creamy white are available on request.
2.2 Inner rubber
 The liner of a rubber membrane seals the pressurized air inside the fenders.
2.3 Synthetic tire cord layers for reinforcement
The reinforcement layers, which are made of synthetic tire cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and to distribute the stress evenly providing strong efficient reinforcement.

2.4 Beading Ring
A steel ring is placed at one end (or both ends) of the fender and holds the end of cord layers.
2.5 Flange
A steel flange is mounted on the fender, to which an air valve or safety valve can be adapted. 
2.6 SafetyValve
Fenders of diameter 2500mm and larger shall be equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally. Fender which are smaller than 2500mm in diameter, can be equipped with a safety valve if required.
2.7 Metal accessories
All the relevant metal accessories of pneuamtic fenders, include shackles, towing rings, swivels, chain net, are made of stainless steel, and H.D.G. which are resistant for sea water corrosion.

The are two typical installation type: ship to ship operation and ship to quay operation

5.1 ship to ship operation
Generally speaking, for the light duty ship to ship operation, two contact points are enough. But for the heavy duty ship to ship operation, 1 or 2 extra pneumatic rubber fender should be used as the primary fendering to absorb the berthing energy, and keep proper stand-off distance between two ships. Meanwhile, two or more small-size fenders can be hung on the ship hull as the secondary fendering.

The pneumatic fenders should be hung by guy chains or guy ropes, which should be selected depending on the different size and weather condition. Evergreen-Maritime pneumatic fenders are supplied with two ends shackles that connect the fender body with guy chains or guy ropes.

5.2 ship to quay operation

Pneumatic fenders are often used for the ship to quay operation because of its excellent performance. The typical installation type is like the follow figure. The pneumatic fenders are anchored with quay by the guy chain and shackles. Meanwhile, the pneumatic fender can be floated on the water surface depend on the change of tide.
