Turret bearing structure for vessels

摘要

A radial bearing arrangement (2) including a turret (14) carried by a vessel (10), the turret (14) having an outer annular rail (38) secured about its outer circumference. The radial bearing arrangement (2) also includes a plurality of rollers (104) attached to the vessel (10) via bearing assemblies (74). The bearing assemblies (74) are arranged and designed to urge the rollers (104) into contact with the annular rail (38), and to limit radial movement of the vessel (10) relative to the turret (14). A plurality of bearing pads (114) are attached to the vessel (10) and positioned circumferentially between the bearing assemblies (74). The bearing pads (114) are arranged and designed to contact the rail (38) under peak loading to limit radial movement of the vessel (10) relative to the turret (14).
