Abstract (en)

[origin: WO9902394A1] A spread mooring arrangement is provided for use in deep water (greater than 200 meters) when it is advantageous to maximize the clearance between shuttle tankers (20) used for product off loading and the anchor legs associated with a spread mooring of the permanently moored tanker (10). Mooring insert tubes are provided at the bow and stern of the vessel. Bow mooring lines (30) extend from the sea floor through an opening of the bottom of the hull of the vessel and via a bow mooring insert tube (100) for securement on a chain pull-up deck (15). Stern mooring lines (40) extend from the sea floor through an opening in the bottom of the hull of the vessel and via a stern mooring insert tube (120) for securement on a chain pull-up deck (15). Space is available on one side of the vessel for a porch (65) for securement of production risers (70), work over risers and control umbilicals, thereby providing flexibility of the use of the vessel for the circumstance where production methods for the oil field change during its leftime or where other fields need to be coupled to the vessel with risers.
