Abstract
A bearing arrangement is described for mounting a turret on the outer ends of beams whose inner ends are supported by a vessel that can weathervane about the turret. A lower bearing arrangement that mounts a lower portion of the turret in rotation about a vertical axis to a lower beam, permits the lower turret portion to pivot about a pair of lower horizontal axes. An upper bearing arrangement that mounts an upper portion of the turret to an upper beam in rotation about the vertical axis, permits the upper turret portion to pivot about a pair of upper horizontal axes.
