ISO17357 marine safety yokohama hydro submarine pneumatic fenders

Hydro-pneumatic Fenders are best employed for berthing Submarines. One of the most important criteria for using Hydro-pneumatic fender is High Energy absorption Capacity and low reaction force, which is vital factor for submarine applications.

The Hydro-pneumatic fender provides a better contact area vertically, which cannot be achieved through any other fender system and hence makes it, the most ideal for submarine use.

The Hydropneumatic fenders can be installed on most Quay structures and come in a range of sizes to suit the application and a range of vessels.

Advantages of JRB pneumatic fenders:

Fender Characteristics

► Cost effective replacement for deep water catamarans

► Easily moved to provide flexibility in berthing

► Easily transported to provide emergency berthing facilities

► Maintenance requirement almost non-existent

► Unaffected by extreme climatic conditions

Yokohama Pneumatic Rubber Fenders are constructed of several layers of strong tire-cord, and are thus resistant to pressure and cutting. The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation. Operational experience over a long period of time attests to its high safety and reliability, and hydraulic pressure tests have proven the strength to be suitable. Furthermore, large-size fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure. The figure below shows data obtained from many destructive pressure tests at various percentage compressions. Such data are used to establish a basic minimum endurable pressure (MEP) curve for pneumatic rubber fenders.

Adaptable to the Tide

Yokohama Pneumatic Rubber Fenders basically float on the water in an unrestricted vertical plane corresponding to the tidal range and ship's vertical movement. This means that energy absorption always takes place at the most suitable position, and that only one fender is required per dolphin.
