ISO17357 Dock Rubber Fender Yokohama Floating Fender CTN Type
Description
Yokohama Fender, also known as Pneumatic Fender, is a common dock rubber fender / floating fender that is used to protect ships and avoid collisions during ship operations. They are also commonly used in the seaport of the wharf to protect ships during berthing operations.
Yokohama 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. 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.
Our yokohama fenders can be provided with a diameter range from 500mm to 4500mm, a length range from 500mm to 12000mm, or special sizes according to customer requirements. These pneumatic fenders are usually equipped with chain nets and tires or wire rope nets, end rings, traction rings and swivel joints, with suitable D-shaped shackles at both ends to increase service life.

The Structures of Yokohama Floating Fenders
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.
Applications
● Offshore platforms
● Oil and gas tankers
● Fast ferries and aluminum vessels
● In ports with extreme tidal variations
● Fishing vessel transport ships and ocean trawlers
