What Are Hydro Pneumatic Fenders?
Hydro pneumatic Fenders, a specialized variant of pneumatic fenders, are designed specifically for submarine docking applications. These fenders contain a mixture of water and air, partially filling them. A counterweight at the bottom of the fender ensures it remains vertically afloat in the sea. This design ensures continuous and effective protection of the submerged hull by the hydro pneumatic fender.
Compared to standard pneumatic fenders, Hydro pneumatic Submarine Fenders have a more complex design and require specific installation techniques. The efficiency of Hydro pneumatic Fenders depends on factors like the air-to-water ratio, the counterweight’s mass, and the initial pressure setting. Jerryborg Marine welcomes your technical specifications to produce hydro pneumatic floating fenders tailored in size and design to meet your operational needs.
