Santa Barbara Salm. a prototype deepwater production riser and floating production system
- Exxon Prod. Res. Co.
A single anchor leg mooring (SALM) is being used in the Hondo field in the Santa Barbara Channel to moor a 50,000 dwt floating storage tanker which will perform oil-water separation, off-loading to a tandem-moored shuttle tanker, and electric power generation for the production platform. The vessel is connected to the mooring buoy via a rigid-yoke structure. The yoke is hinged at the ship end to allow articulation in a vertical direction, i.e., to take out the pitch motion of the vessel. The rigid yoke has a full three degrees-of-freedom joint (triaxial universal joint) on top of the buoy that allows the yoke to roll, pitch, and weather vane independent of the buoy structure. The mooring buoy consists of an upper buoyancy chamber and a lower extension tube which is flooded. The buoy provides the over-all restoring force for the system and must be stable under all static and dynamic loading conditions. A tubular riser connects the mooring buoy to the base on the ocean floor. The riser unit is designed for 100 yr storm conditions and will withstand the maximum expected earthquake loading with the vessel attached.
