A lower bearing arrangement between a turret of an FPU and a moonpool. The outer housing of the bearing is mounted about the turret instead of the FPU's hull structure. Bearing segments are captured between an outer ring of the turret and an inner ring of the outer housing. The outer housing of the bearing assembly is coupled to a reaction ring of the moonpool so that rotation forces of the vessel are transferred to the outer housing of the bearing. The coupling also includes an arrangement by which the outer housing contacts said reaction ring in the nature of a spherical joint.
