Abstract: Disclosed is a single point mooring system for mooring vessels at a certain distance from offshore structures. The system includes a buoy positioned in the water and a cable attached at one end of the buoy and attached at the other end to a reel or the like for reeling in or reeling out cable to move the vessel back and forth relative to the buoy. Another cable is attached to the buoy and depends downwardly therefrom into the water where it is attached to a sinker ball resting on the bottom. An anchor is connected to the sinker ball.

Abstract: A bumper assembly for a marine structure is disclosed, comprising an essentially vertical frame member mounted by energy absorbing shock members at each end thereof to a stationary offshore structure, the vertical member carrying annular bumper members stacked thereon. The vertical member comprises concentric cylinders in order to extend the length thereof slightly as the shock absorbing members are actuated so that the movement of such shock absorbing members remains linear. At each end of the vertical support member, at the point of attachment of the shock absorbing member, a supporting chain or cable is attached to support such vertical member to prevent the vertical member from creating a cantilever effect on the shock absorbing members.
