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.

Hydropneumatic Fenders require some special installation techniques to be installed. The performance of Hydropneumatic Fenders is affected by the air:water ratio and the initial pressure. Hongruntong Team would be pleased to receive your design input allowing us to engineer the correct type, size and overall layout of the Hydropneumatic Fender suiting your requirements.
