ISO17357 Certified D3.3M Hydropneumatic Submarine Fenders Black Color Counterweight
Description
The Hydropneumatic Submarine Fenders are a special version of the Pneumatic Fender developed for submarines. Submarine 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.
Hydropneumatic Submarine Fenders require some special installation techniques to be installed. The performance of Fenders is affected by the air:water ratio and the initial pressure.
