Hydropneumatic Fenders

QSF Hydropneumatic Fenders protect submarines, and other vessels that make contact below the waterline. They are filled with water and air then fitted with a counterweight that holds them upright against submerged hulls.

QSF Hydropneumatic Fenders can be performance ‘tuned’ by varying the initial pressure, water to air ratio, and ballast weights to suit the hull curvature and sensitivity of the latest submarines. We can also allow for polytropic conditions (saturated air), and other variables.
