The Hydropneumatic Fender is a special version of the Pneumatic Fender,which is developed for submarine docking. Hydropneumatic Fenders are partially filled with water and air. There is a counterweight connected at the fender bottom to keep them floating vertically in the sea. In this way, the submerged hull is effectively protected by the hydropneumatic fender all the time.
Hydropneumatic Submarine Fenders are more complicated design than standard pneumatic fenders, so they need some more special installation techniques to be installed. The performance of Hydropneumatic Fenders is affected by the air:water ratio, weight of counterweight and the initial pressure. Jerryborg Marine is pleased to receive your technical requirements allowing us to manufacturer the right type hydropneumatic floating fenders, size and overall design which suit your actual operation demand.
