The Hydropneumatic Fender is a special version of the Pneumatic Fender developed for submarines. Hydropneumatic Fenders are partially filled with water and air and are equipped with a counterweight in order to keep them in a vertical position. This ensures that the submerged hull is properly protected by the fender at all times.
