First year's operation experience of the deepest SPM (Single Point Mooring) in the world
The British National Oil Corp. had a Single Anchor Leg Mooring (SALM) installed at the Thistle Field in Apr. 1977 for export loading of tankers pending completion of the Brent System 36 in. pipeline to Sullom-Voe, which became operational in Dec. 1978; the SALM will continue to be maintained in good condition as a standby alternative export outlet. Modification of the original three 80,000 dwt tankers during 1977 provided the original design capacity of an 80,000 dwt tanker, but with added clean ballast capacity to eliminate tank cleaning and treatment of dirty ballast water. A fully integrated tanker/SALM/platform instrumentation system monitors mooring loads, buoy and riser angles, and tanker status; the latter being radio telemetered to the nearby block platform. Operation of the system and necessary modifications are described.
