Hydro pneumatic fender Introduction
SunHelm SH-DM Deep Marine Hydro pneumatic fender is a special version of the Pneumatic Fender developed for submarines. Hydro pneumatic 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. Hydro pneumatic Fenders require some special installation techniques to be installed. The performance of Hydro pneumatic Fenders is affected by the air:water ratio and the initial pressure.SunHelm would be pleased to receive your design input allowing us to engineer the correct type, size and overall layout of the Hydro pneumatic Fender suiting your requirements.
