ABSTRACT:
A system for transporting hydrocarbon fluid produced from an offshore well using an offshore production platform and a hydrocarbon fluid storage space in fluid communication with the offshore well via a conduit is provided. The system comprises at least one hydrocarbon fluid export system including a shuttle tanker provided with positioning apparatus capable of limiting movement of the tanker away from a location at a selected distance from the production platform, a flowline for transferring the hydrocarbon fluid to the tanker, at least pan of the flowline being a continuous flexible flowline at one end provided with a connector for releasably connecting the flowline to the tanker so as to allow fluid transfer from the flowline to the tanker, and with a valve for opening or closing the flowline, the flexible flowline extending along the seabed and from the seabed in the form of a riser to the tanker when the flowline is connected to the tanker. The riser includes a buoyancy section provided with a plurality of buoyancy modules attached to the riser at selected mutual distances and located so as to configure said riser in a double-catenary configuration, the riser being free to move in response to movement of the tanker. Apparatus for moving the upper end of the riser between the seabed and the tanker when the flowline is disconnected from the tanker, are preferably included.
