Rigid Arm SPM Buoy system
The single point mooring buoy with rigid arm system includes a rigid steel frame that is connected between vessel and buoy by means of large hinges.
This requires a dedicated vessel as the hull structure is modified to support these hinges. The hinges reduce the forces on the rigid arm as both the vessel motions and the buoy motions are not fully coupled. The rigid steel frame keeps the distance between the vessel and buoy fixed, allowing permanent mooring of the vessel without the need of thrust astern.
The rigid arm system can also be combined with a fluid transfer system. The fluid path between the buoy and the dedicated tanker is realised by means of jumper hoses.
