DUAL FUNCTION MOORING LINES FOR STORAGE VESSEL

摘要

An improved vessel mooring system in which a storage vessel (10) weathervane s about a mooring base (16, 27) supported by the vessel for relative rotation. A plurality of flexible tubular dual function mooring lines (20) extend from t he mooring base (27) to the sea floor (14) and thence to a subsea production facility (40). The dual function mooring lines (20) have collars (34) thereo n which are anchored to the sea floor (14) by anchors (38). Product from a subsea production facility (40) is transported through the dual function mooring lines (20) to storage areas in the vessel (10).
