Protection device for a turret bearing

摘要

Protection device for a turret bearing arranged between a floating structure and a mooring member. A turret bearing is arranged at or below water level to provide an effective introduction of forces as near the lower side of the floating structure as possible. To guarantee lubrication of the turret bearing a labyrinthine chamber is provided around the turret bearing. The downwardly extending part of this chamber is realized by the floating structure and more particularly a reinforced box whilst the upwardly extending part is provided by a wall extending from the body of the mooring member.
