Yokohama Pneumatic Fenders for Ship/Dock/Marine

Product Description

1. General introduction

ISO17357:2014 Floating pneumatic rubber fender is an anti-clossion device for marine application in the world. It is made of synthetic-cord-reinforced rubber sheet with compressed air inside to enable it to float on the sea surface and work as a shock absorber when ship to ship transfer operation and ship to dock berthing and mooring operations.

Evergreen floating pneumatic rubber fenders fully company with all requirements on ISO17357:2002 Sstandard. Our products are certificated by CCS, DNV, GL, LR and BV.

2. Construction features

All of these layers are vulcanized together ,and then compress air inside to enable the fender to float on the sea surface.

6.Application

There 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.
7.Pressure requirements of Yokohama type Pneumatic Rubber Fenders -

Evergreen-Maritime manufactures marine rubber fender with 50kPa (pneumatic 50) and 80kPa (pneumatic 80) initial pressure. The internal pressure, endurable pressure, safety-valve setting pressure and hydraulic test pressure are also in compliance with the requirements of ISO17357:2002.
Fenders of diameter 2500mm and larger equipped with safety valve for releasing excess internal pressure when the fenders are over-compressed accidentally.
