Yokohama Fenders ISO17357 Specifications with Aircraft Tires for STS Operations

Description

Yokohama fenders, also known as floating fenders, provides the supplementary protection to applications where fixed fenders such as cylindrical fenders and arch fenders may be unsuitable. With low reaction force at low deflection, yokohama fenders are the best choice for liquid cargo vessels and defense vessels with sensitive equipment.

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, yokohama 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 yokohama 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.

Specifications

Yokohama fenders are composed of 4 main parts:

Outer rubber, reinforced tyre cord, inner rubber and end flanges.

Outer rubber layer features high tensile strength and wear resistance to protect reinforced tyre core and inner rubber form damages.

Reinforced tyre cord is fabricated from high strength cord materials to strength the pneumatic fender.

Inner layer is made of rubber to contain the air and avoid any leakage.

End flanges are the junction of rubber bladder and metallic parts containing air valve, which are used to fill and discharge gas. Meanwhile, the end flanges have hoisting rings to allow the fender to be lifted easily.

How does the yokohama fender work?

The yokohama fender uses compressed air as a buffer medium to absorb the impact energy of the ship when the two ships are close or the ship is close to the dock, so that the ship can avoid big losses due to collision. At the same time, the ship has more flexibility when docking.
