Submarine hydro halfdive vertical pneumatic marine rubber fenders is mainly for vessels like drilling rigs, catamarans, semi-submersible platforms while their contact is below water.
Construction feature of submarine pneumatic rubber fenders
We manufacture rubber submarine hydro 0pneumatic marine fenders according to International Standard which is partially air pressured and left water filled. This design of submarine hydro pneumatic marine rubber fenders deep draft, stable and soft for delicate hulls. A ballst weight is 
suspended from the hydro vertical pneumatic marine fenders and it can be used to vary the submarine fender level to suit for different classes of vessels. Bottom end of the hydro vertical pneumatic rubber fender is installed with an ballst weight to stop hydro vertical pneumatic marine fenders from flipping.
Performance of submarine fenders (hydro vertical floating pneumatic fenders)
Light weight submarine hydro pneumatic marine fenders could be varified from internal operating pressure of the submarine fender. We have two standard internal pressure ratings 50 kPa and 80 kPa.
Installation of submarine pneumatic marine rubber fenders
Submarine pneumatic marine fenders can be equipped on most quay structures and come in a range of sizes to suit the application and a range of vessels.
