Submarine Hydro Pneumatic Fender

 

The Hydropneumatic Fender is a special version of the Pneumatic Fender developed for submarines. They are filled with water and air then fitted with a counterweight that holds them upright against submerged hulls, Hydropneumatic Fender are designed to be installed vertically making them ideal for use with submarines or vessels whose impact point is likely to be below the waterline such as Catamarans, Semi-Submersible platforms and Drilling Rigs, protecting submarines and other vessels that make contact below the waterline.

JRB 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.

The Hydropneumatic fenders can be installed on most Quay structures and come in a range of sizes to suit the application and a range of vessels.

Advantages of JRB pneumatic fenders:

 

1 Performance can be adjusted by altering the air-water ratio
2 Required draft can be adjusted
3 Low hull pressures
4 Self-adjustment during tidal variation
5 Low installation and maintenance cost

Safety and Reliability
 
 Pneumatic Rubber Fenders are constructed of several layers of strong tire-cord, and are thus resistant to pressure and cutting. The safety factor adopted in the design of this fender is based on accepted theory and has been proven by extensive experimentation. Operational experience over a long period of time attests to its high safety and reliability, and hydraulic pressure tests have proven the strength to be suitable. Furthermore, large-size fenders are equipped with a safety valve to release the inside air in the event of accidental over-pressure. The figure below shows data obtained from many destructive pressure tests at various percentage compressions. Such data are used to establish a basic minimum endurable pressure (MEP) curve for pneumatic rubber fenders.
