An arrangement for in situ remediation of a bearing assembly rotatively coupling a vessel to a turret about its longitudinal axis. An inner ring assembly is coupled to the turret and an outer ring assembly is coupled to the vessel. A support row assembly connected between the inner and outer ring assemblies allows rotation of the outer ring assembly with respect to the inner ring assembly and axially transfers the turret weight to the vessel. A radial row assembly and a centralizer are disposed between the inner and outer ring assemblies. The radial row assembly normally transfers radial load from the vessel to the turret and the centralizer has a radial clearance with the outer ring assembly. During in situ repair of the radial or support row assembly the centralizer transfers radial load from the vessel to the turret and maintains substantial concentricity of the inner and outer ring assemblies.
