Abstract (en)

The present invention relates to an arrangement in a floating drilling and intervention vessel (16), for controlling a heave compensated drill floor (7) suspended in drill floor compensator cylinders (10). Below the compensated drill floor (7) there is installed a tidal structure (3) suspended in tidal cylinders (2) or wires (25). By adjusting the tidal cylinders (2) or the wires (25) in step with the tide (17) it is achieved that the drill floor compensator cylinders (10) can operate around their middle position regardless of the tide lifting or lowering the vessel (16). <IMAGE>
