Abstract (en)
[origin: WO8001181A1] A device, controlling the relative vertical displacements of the bridge (1) and of the feet (2) of a sea platform, comprises on one hand toothed-racks (31, 32) cut out in pillars (3) fixed to the feet and on the other hand locomotor units (5) which comprise each a frame (51) fitted with gears (55) rotatingly driven by motors (57, 58) and meshing with said toothedracks, and substantially characterized in that each frame of locomotor unit is attached by a joint (41) to a coupling rod (4) which extends along the pillar and is connected by a joint (42) to the bridge and associated to balancing means (81, 82, 83) of the reverse torque generated by the effort transmitted by said coupling rod. The device is intended to a platform for oil drillings.
