Description:
Hydropneumatic Fender is a special version of the inflatable fender developed for submarines. Because they can be filled with water or air and equipped with counterweights, they can stand upright against the diving hull. The water-filled fender is designed to be installed vertically, which is very suitable for use with submarines or ships whose impact point may be below the waterline, such as catamarans, semi-submersible platforms and drilling rigs, to protect submarines and other ships that come into contact below the waterline .
In use, you can "adjust" Hener's water-filled fender performance by changing the initial pressure, the ratio of water to air and the ballast weight to adapt to the hull curvature and sensitivity of the latest submarine.
Water-filled fenders can be installed on most wharf structures and come in various sizes to suit various applications and various ships.
