  • Patent number: 6126501
    Abstract: A mooring system employs a vessel mounted turret in combination with a submerged chain table that also acts as a clump weight. The chain table is submerged fairly close to the sea surface at approximately the keel depth of the vessel, or a few meters below that depth. Three or more chains connect the vessel mounted turret and chain table to one another, preferably though corresponding U-joints. Several mooring lines are attached at first ends to the bottom of the chain table, and are secured at second ends to anchors or piles in the seabed. The weight of the chain table is chosen so that it helps reduce the stresses imparted by the vessel to the mooring lines, thereby reducing the maximum load requirement, and thus cost, of the mooring lines.
