A mooring assembly for a vessel comprises a moonpool having a casing, a turret positioned in said moonpool and mounted therein for a rotation by means of an upper bearing assembly and a lower bearing assembly and mooring lines attached to a lower part of the turret. The lower bearing assembly comprises a stiff inner bearing ring attached to said lower part of the turret, an outer bearing ring attached to the casing of the moonpool and a number of circumferentially spaced bearing blocks positioned between the inner and outer bearing rings. Mounting means are provided for maintaining a substantially fixed position of the bearing blocks relative to the outer bearing ring. The mounting means are devised for allowing the bearing blocks to carry out a settling movement relative to the outer bearing ring for assuming a position in which the load transfer between the bearing blocks and outer bearing ring occurs with a minimum of stress concentrations within the outer bearing ring and wherein the larger part of the load transfer occurs directly between the bearing blocks and outer bearing ring without being directed through the mounting means. |
