THE SEA RATCHET

The SEA RATCHET is a device which will substantially reduce wave induced motions as well as increase deck loading flexibility. Slung deeply beneath existing semisubmersibles using chains, the ratchet action results from its upward only damping action entraining a hundred thousand tons of apparent mass. Filmed scale model tests have been conducted.
