Offshore and Marine Fenders : Large Sizes

Mainly fenders for use in the maritime and offshore industry have large dimensions. We supply them in different types, materials, hardnesses and sizes. We supply various standard types:


The D fender is the most commonly used rubber bumper. The D fender has a flat back, which makes it easy to install on various surfaces. This can be done by means of bolts and/or strips in various manners: horizontally, vertically or diagonally. Mounting holes are made through the top and bottom of the fender, or through the sides.

There are three different types of D fenders available:

  • With an inner chamber, D-shaped
  • With an inner chamber, O-shaped
  • Solid, without an inner chamber.

Delta Fender

The delta fender is easy to install and has a minimal contact surface. Mounting holes are made through the top and bottom of the fender. A properly mounted delta fender is able to absorb high levels of energy because of a relatively large inner chamber.

Cylindrical Fender

Cylindrical fenders absorb forces and loads very well. These marine fenders are simple to install. It can be mounted horizontally, vertically or diagonally using chains or rods.

Square Fender

A square fender is used when a more rigid and stronger bumper is required for use in heavy duty applications and the D fender does not comply.

Keyhole Fender A keyhole fender absorbs large forces. These marine fenders are usually mounted vertically with fixing pins through the two standard holes on the bow of a vessel or the wall of a quay. The keyhole fender can be produced with an UHMPE surface layer.
M-Fender The M fender has a wide and flexible contact surface. The M shape provides flexibility. Therefore, it can easily follow the contour of a bow or stern. The M fender is often installed vertically with the help of fixing pins through three standard openings.
W Fender The W fender is used to absorb excessive shocks and impacts in extreme conditions. That is why this type of fender is used on the bow and stern of workboats such as pipe and cable laying vessels. This fender is often attached vertically with fixing pins through the two standard holes.
