MOORING ASSEMBLY FOR A VESSEL

摘要

A mooring assembly for a vessel (1), comprising a moonpool (2) defined in the vessel, a turret ( 3 ) rotatably mounted within the moonpool by means of an upper main bearing (4) and by means of a lower secondary bearing (5), and mooring lines (6) attached to the lower region of the turret, the turret at its lower region comprises a number of circumferentially spaced torsion box like torsion members (7) each extending substantially vertically between an upper end attached to the turret and a lower free end. Said torsion members have a resistance against bending that in a circumferential direction is greater than in a radial direction. The mooring lines are attached to said torsion members near said lower free ends and the lower secondary bearing is defined by outwardly facing bearing members (8) attached to said torsion members and an inwardly facing bearing ring (9) attached to the moonpool. In a situation in which a torsion member is not loaded horizontally by a respective mooring line its bearing member does not engage the bearing ring.
