Pneumatic fenders are rubber fenders filled with air (hence the name pneumatic fenders).

A fender is a bumper used to absorb the kinetic energy of a boat or vessel berthing against a jetty, quay wall or other vessel. Fenders, used on all types of vessels, from cargo ships to cruise shipsferries and personal yachts, prevent damage to vessels and berthing structures.

Advantages of Pneumatic Fenders:

  1. Advantages during inclined berthing

During berthing, the initial contact with the dock is usually at an oblique angle and that places a lot of pressure on both surfaces (the dock and the ship).

  1. Stronger against shearing force

After contacting the dock, the vessel is usually slowly moved to the optimum mooring position. This action exerts high shearing force and compression on the surface of fenders. Most solid fenders are severely damaged due to such forces as they are not designed to withstand strong shearing forces and friction that way.

  1. Relatively safe even during excess load

All fenders should be used within the impact load limit. In real life, it is common to see that fenders often accidentally receive excess loads. When that happens, the fortunate thing about a pneumatic fender is that the reaction force does not increase sharply under excessive load.

  1. Advantages during crucial weather conditions

During crucial weather conditions when the wave action is severe, mooring processes are further complicated due to up and down unbalanced action at the quay. This exerts a higher shearing force on the fenders and the frequently change in forces during mooring under such weather conditions will cause fatigue on typical solid type fenders.
