Safety and Reliability

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.

Advantages at Inclined Berthing

Ships usually make initial contact with the dock or another ship on STS operations at an oblique angle. In the case of solid rubber fenders or foam fenders, rated reaction force and energy absorption decreases considerably at inclined compressions compared with parallel compression. In order to compensate for the decrease of energy absorption at inclined compression, it is necessary to use larger sizes in the case of solid rubber fenders or foam fenders.

Stronger against Shearing Force

After contacting a dock, a ship is usually shifted to the correct mooring position. The shifting exerts shearing and compression forces on the fenders. This combined force is very severe in the case of solid rubber fenders because they are not reinforced against such force. In contrast, Yokohama Pneumatic Rubber Fenders are adequately reinforced using strong tire-cord to cope against such forces as well as internal pressure.
