Apparatus for single point mooring
A single point mooring apparatus especially adapted for securing large marine tanker vessels or subsea hydrocarbon well collection and storage barges in relatively shallow water is disclosed. The floating mooring buoy structure is connected to a mooring base secured to the ocean floor by a plurality of tension leg attachment members of predetermined length. The buoyancy of the floating buoy structure is controlled to produce sufficient tension in the attachment member to provide a position restoring force to the moored marine vessel. The floating buoy structure is formed by an open frame work having a conical shape to minimize impact with ice floes on the floating buoy structure and have fully submerged buoyancy tanks to minimize the effect of wave forces and tied level variations on the position restoring force.
