Abstract
An offshore system is described, of the type that includes a turret (20) anchored to the sea floor and connected by at least an upper bearing assembly (34) to the vessel hull (14) so the hull can weathervane about the turret, wherein the upper bearing assembly is of moderate cost and high reliability, is easily maintained, and accommodates vessel hull deformation. The upper bearing assembly includes a circle of bearing devices(202) wherein each device includes a cylinder (224) and piston (226). A source (260) of pressured fluid is applied to the devices to push apart the cylinder and piston to support an upper bearing part (204) of the turret on a lower bearing part (210) of the hull.
