Patent ID: 7470163

Claim:
A combined riser, offloading and mooring system for the offloading of hydrocarbons from a floating production vessel to an export tanker, the floating production vessel receiving the hydrocarbons from a production riser and delivering them to the tanker through an offloading fluid jumper line, the system comprising: an offloading buoy system for supporting the production riser and fluid jumper line, the offloading buoy system comprising: at least one offloading buoy mooring line forming a mooring line axis from an earth mudline; an offloading buoy connected to the at least one offloading buoy mooring line, the offloading buoy being disposed substantially in the mooring line axis; a riser buoy, wherein the riser buoy: is submerged beneath the offloading buoy is also moored by the offloading buoy mooring line; is also disposed substantially in the mooring line axis formed by the at least one offloading buoy mooring line; and is connected to the offloading buoy by an inter-buoy mooring line; a fluid conduit connector for providing fluid communication between said fluid jumper line from the floating production vessel and an offloading hose to the export tanker; and a riser connector providing fluid communication between the production riser and a production jumper to the floating production vessel said riser connector being tied to said at least one offloading buoy mooring line; at least one set of FPV mooring lines for securing the floating production vessel to the offloading buoy system; and a hawser line for connecting the tanker to the offloading buoy system.
