Pneumatic Fender | Yokohama Fender

Pneumatic Fender is made of the synthetic-cord-reinforced rubber sheet with compressed air inside, at an initial pressure of 50kpa or 80kpa, to enable it to float on the water and work as a shock absorber between two ships.
Description

As a leading anti-collision device, pneumatic fenders have a long and successful history of protecting vessels in mooring operations. They are ideal for permanent and semi-permanent port applications, as well as for offshore ship-to-ship transfers. Our fenders are fast and easy to install, keeping suitable clearances between the hull and the jetty or vessels. its aim is to minimize potential damage during berthing operations. These fenders play a critical role in the safe operation of ship berthing.


The Structures of Pneumatic Fenders:

The pneumatic fender is constructed of an inner rubber, synthetic-tire-cord layer, and outer rubber. All of those shall be vulcanized firmly and proven by compress test.
- Outer rubber layer covers the outside of the fender to protect the cord layers and the inner liner rubber from abrasion and other external forces.
- Inner rubber layer of a rubber membrane that seals the pressurized air inside the fender.
- Synthetic-tyre-cord layer for reinforcement layer made of synthetic-tire-cord fabric, which maintains the internal air pressure of the fender.
