The system comprises a floating body such as a buoy or barge, connected to an anchoring base by at least one arm articulated to the base by a universal joint. The inclination of the arm can then vary according to the wind and current. Preferably the buoy is rigidly fixed to the arm. The inclination of the arm is particularly in the range 20 DEG to 45 DEG . The buoy may be flat and bear equipment such as winding drums for a flexible tube, for instance connecting a petroleum tank on the sea-bed to a ship. A pump may be arranged for actuation by the swell to drive equipment on the buoy through a hydraulic motor. |
