Buoyant Turret Mooring

The Buoyant Turret Mooring (BTM) system consists of a disconnectable mooring buoy and a fixed turret structure located inside the forepeak of the tanker.

The mooring buoy is fixed to the seabed by catenary anchor legs and anchor points. The mooring buoy, located below the tanker keel, supports the fluid risers and is connected by means of a structural connector to the fixed turret structure. The fixed turret structure extends up through the tanker and is supported from a roller bearing. At the top, it contains the reconnection winch, flow lines, control manifolds and fluid swivels.

When disconnected the mooring buoy sinks to a neutral buoyancy position under water, out of harm’s way, and the FPSO sails away to safer waters.
