Title: Combined catenary and single anchor leg mooring system

Abstract: A combined catenary and single anchor leg mooring system capable of transferring cargo from vessels moored thereto includes an anchor hub suspended by a single anchor leg from a mooring buoy floating on the surface of the sea. A plurality of catenary anchor legs connect to the anchor hub and extend outward and downward to anchors secured in the sea bottom. A cargo transfer swivel assembly is mounted on the anchor hub, and is rotatable about the lower connection point of the single anchor leg. Cargo hose extends from a pipeline manifold located on the sea floor to piping in the anchor hub, and additional cargo hose extends from the swivel assembly to the sea surface and then to the moored tanker.
