Pneumatic Rubber Fenders(Pneumatic Yokohama  fender)

Pneumatic fenders, also called yokohama rubber fender, is a leading anti-collision device for marine application in the world today. This compressed air rubber fender is used as a protective medium. Therefore, pneumatic rubber fenders serves as a protective medium against collision when ship-to-ship contact (STS) and ship-to-berthing (STB). Pneumatic fenders has the advantages of massive energy absorption with low unit surface pressure acted upon the ship. So penumatic fenders has become an ideal ship protection medium used extensively by large tankers, LPG vessels, ocean platforms, large docks, harbor and wharfs.

Core attributes
Pneumatic rubber fenders have any advantages including:
*Easy and fast to deploy;
*Very low reaction and hull pressure;
*Performance adjustable by varying initial pressure;
*Suitable for areas with large or small tides;
*Maintains large clearances between hull and structure;
*Optional chain-tyre nets for heavy duty applications;
*Low maintenance.

Application
Pneumatic yokohama rubber fenders are suitable for many applications including:
*Tankers, Gas Carriers and Bulk Cargo Ships;
*Fast ferries and aluminum hulled vessels;
*Temporary of permanent installations;
*Rapid response and emergency fendering;
*As stand-off fenders to realign ships with shore facilities.

Notes:
1. Guaranteed energy absorption represents the guaranteed energy absorption at 60% deflection.
2. Tolerance of reaction fore and deflection are as follows: Reaction:10%, Deflection:5%.
3.  Each reaction and energy absorption is measured under static conditions.
4.  Testing pressure rate indicates the testing pressure at the factory.
5.  Weight of fender body and net may vary 10%.
6.  Special sizes are available upon request.
7.  Different levels of performance according to internal air pressure levels specified this fenders.
