Abstract
An apparatus for rotating a floating vessel such as a ship, around a cylindrical turret structure moored to the sea bottom. The vessel has a circumturret structure passing through the hull of the vessel and surrounding the turret structure. The apparatus comprises a hook roller assembly, a load roller assembly, a radial roller assembly, and a drive mechanism. The hook roller assembly prevents the turret structure from moving upward from the wave and current forces exerted on the floating vessel. The load roller assembly rotatably supports the turret structure on the circumturret structure. The plurality of radial roller assemblies mounted to the circumturret radially support the turret. The drive mechanism is used to rotate the vessel around the turret.
