FLUID AND ELECTRICAL TRANSFER FROM MID-POSITIONED TURRETS ON SHIP- SHAPED FPSOS USING DRAG CHAIN TECHNOLOGY

Ship-shaped FPSO vessels with mid-positioned turrets, particularly for use in harsh environments, present particular problems in transferring all fluid and electrical connections from sub- sea to process or vice versa. The turret is moored to the sea-bed with the vessel rotating about this fixed turret to be in optimum position taking account of sea and wind conditions. Risers coming from sub-sea to the turret have to be connected to the process equipment on the vessel deck whilst this rotation takes place. Currently there are two types of system in operation in the North Sea to enable this to happen: axial and/or toroidal swivels and turret transfer systems based on drag chain technology. This paper addresses the use of drag chain technology for this application.
