World-leading supplIER and manufacture

Submarine fenders

Fendercare Marine has supplied Yokohama submarine fenders to many navies around the world, including those of Australia, Brazil, Canada, Greece, Japan, the United Kingdom and the USA. The Yokohama submarine floating fender was launched in 1984 and since then has been extensively used by navies across the world.

Advantages of fenders over alternative, traditional berthing methods include:

  • 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

Surface & subsurface fenders

In order to provide full protection at surface and subsurface, our submarine fenders are deployed vertically. To maintain their position, the fenders are water ballasted and also have a counterweight attached to the bottom of the fender. The weight, shape and method of deployment of the counterweight can be adjusted to suit individual situations.

Submarine fenders are designed to offer higher bursting strength than a normal surface fender, with the minimum burst pressures being:

  • 2000mm diameter and smaller = 4.9kgf/cm2
  • 2500mm diameter and larger = 5.7kgf/cm2

To facilitate water charge and discharge, flange openings are sited at each end of the fender. In addition, submarine fenders are fitted with a safety valve to enable excess pressure to be released should over compression occur.
