1. Soft Reaction Force for Ship and Jetty Structure

Although all fenders should be used within their maximum load limit, it often happens that fenders accidentally receive excess load. The reaction force of Yokohama Pneumatic Rubber Fenders does not increase sharply, even under excess load conditions. Therefore, the Yokohama Pneumatic Rubber Fenders perform well in such cases, and protect ships and mooring facilities. In contrast, the reaction force of solid rubber fenders, including buckling-type fenders, increases sharply under excess load conditions. The excess load turns the solid-type fender into a solid rubber block, which cannot perform as a fender. This often leads to damage of the ship and mooring facilities.

2. 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.

Reduction of Energy Absorption at Inclined Berthing for Pneumatic, Solid and Foam Fender
In the case of Yokohama Pneumatic Rubber Fenders, energy absorption does not decrease at inclined compression up to 15 degrees.

Load Distribution at Inclined Berthing for Pneumatic, Solid and Foam Fender

Distribution of load is also comparatively even because of the molecular freedom of air and high flexibility of the multi-layered cord-reinforced rubber membrane. This makes the body of a pneumatic rubber fender more shape conformant compared to solid or foam fenders, and thus able to better distribute the load along the hull of a ship or jetty structure during inclined compression.
