Abstract
Mooring apparatus and method of use thereof, for marine vessels, comprising a subsea anchor (12) such as a suction pile (14A), and including a swivel (16) to which at least one mooring line (24) is connected, the other end of the mooring line being adapted for connection to the bow mooring apparatus of a marine vessel (22) such as a conventional tanker. The mooring line (24) includes a load cell for measuring tension applied to the line by reverse thrust of the vessel. Signals from the load cell are transmitted from the bow of the vessel to the bridge (40), enabling manual, automatic or semi-automatic control of the applied tension. In use, the mooring line is maintained under tension such that the vessel may weathervane around the swivel. The system may be employed as part of a subsea fluid product export system for offloading the product to a tanker moored using the system, employing a flexible riser (20) having its lower end connected to a subsea product source and its upper end connected to the fluid manifold of the tanker via a floating hose assembly (34).
