Portable Cord Jacket Pneumatic Dock Marine Rubber Fender
Yokohama Trelleborg ISO17357 2.0x3.5 pneumatic marine rubber fender price
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

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.
Construction features
Floating pneumatic rubber fenders shall consist of an out rubber, reinforcement synthetic-tyre-cord layer, and inner rubber, vulcanized firmly.
The out rubber are used to protect the cord layers and inner rubber from abrasion and other external forces. This rubber compound have sufficient tensile and tear resistance strength to withstand anticipated weather conditions and severe usage.
The reinforcement synthetic-tyre-cord layer strong enough to maintain the internal air pressure of the fenderThe inner rubber layer seals the pressurized air inside the fender
Fenders of diameter 2500mm and larger equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally.
The properties requirements of outer and inner rubber material of floating pneumatic rubber fenders comply with ISO 17357:2014.
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.
Floating Pneumatic Rubber Fender Performance
The performance of floating pneumatic rubber fenders shall be specified in terms of Guaranteed Energy Absorption (GEA), Reaction Force at GEA deflection, and Hull Pressure at GEA deflection.

Floating Pneumatic Rubber Fenders which is made of synthetic-cord-reinforced rubber sheet with compressed air inside to enable it to float on the water and work as a shock absorber between two ships (ship-to-ship), or between ships and berthing structures when they come alongside each other on the water.
Advantages of Floating Pneumatic Rubber Fenders
Floating pneumatic rubber fenders can be easily handled and installed with guy-rope or guy-chain because of its light weight. It can resist the shearing force and maintain energy absorption level under inclined compressionup to 15 degrees. Meanwhile, provide the low and comparatively even hull pressure.
Consisted of several synthetic-cord layers and tough abrasion resistant out rubber, they have consistent performance even under rough condition and cyclic load. The maintenance cost and damage risk are minimised too. The best material also ensure the self-buoyancy and extremely long service life.
Floating Pneumatic Rubber Fenders Requirements

Test and Inspection for Commercial Floating Pneumatic Rubber Fenders
Acceptance testing and inspection for purchased floating pneumatic rubber fenders shall be based on the tests and inspections indicated below:
Material test of rubber - Conducted in accordance with the Physical properties of inner and outer rubber required by ISO 17357:2002
Dimensional inspection - shall be inspected at the initial internal pressure. Tolerance: +10%, -5%.
Air-leakage test - shall be conducted at initial pressure for more than 30 min
Hydrostatic-pressure test - shall be performed for 10 min at the hydrostatic pressure shown in "test pressure at 0% deflection". Maximum temporary elongation: 10%
All Evergreen Maritime floating pneumatic rubber fenders are manufactured and third party (ABS, LR, BV, CCS) certified in compliance with ISO 17357:2014.
Pneumatic fenders have the advantages of massive energy absorption with low unit surface pressure acted upon the ship.
