BP’s Skarv field plan uses a turret-moored FPSO in 375 m (1,230 ft) water depth in the North Sea. The FPSO has a heading control system as the turret, positioned 1/3 of the ship’s length aft of the forward perpendicular, to reduce weathervaning. This approach meets both Norwegian regulations and BP’s specifications. To meet the harsh environment and specified response to complete heading control power loss, loads on the mooring are in excess of 5,000 tons. The internal turret at Skarv is suited to these requirements by a design that transfers mooring loads from the chaintable through the turret cylinder to the main deck, and to the vessel through the bogie bearing system. The author examines the specifications for the turret and the design methods used to meet them.
