ISO17357 Specifications Yokohama Fenders Floating Fender for STS Operations
Net-type fenders are covered with a chain net, wire net or fiber net for fenders. Usually these nets have used-tires together with rubber sleeves for additional protection, except fiber net which has only rubber sleeves. Chain nets last longer against corrosion, while wire nets are light and more easily repaired.
Yokohama fenders have become an ideal ship protection medium against collision among ship-to-ship (STS), ship to quay (STQ) and ship-to-berthing (STB), they are widely used for large tankers, vessels, docks, harbor wharfs and ocean platforms.
The yokohama fender is specifically designed for heavy duty marine and offshore use. The construction of the fender makes it ideal for protecting ships and quays from the forces involved when mooring, either ship-to-ship or ship-to-quay.
Our fender is manufactured and tested in accordance with ISO 17357:2014-1. This is the only standard ensuring high quality fenders. Each fender can be supplied with individual class certificate (ABS) showing conformance to ISO 17357:2014-1.

Fender Structure
1. Outer layer
Cover outside on the ball of rubber layer, which is used to protect skeleton material and inner rubber ball from damage of external force.
2. Reinforced layer
Reinforced cord rubber layer is composed of winding synthetic cord layer, it is mainly used for maintain the internal air pressure.
3. Inner Rubber
On the ball inside the rubber layer, which is used to prevent air leakage and control the ball pressure.
4. End Flange
The metal parts at both ends of fender, which can be fitted with charging valve and safety valve.
