The present invention relates to an arrangement in a floating drilling and intervention vessel, 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.

The invention is a method and device of slope rock anchoring construction by using cables to pull drill floor for locating and applying pressure. The method: according to the six (or four) anchoring points preset in the range of anchoring operation surface, linking two points in the high position by a steel cable, hanging the drill floor under the pulley rolling on the steel cable through pulley group, using a steel rope fixed on the ground for lifting the jenny to make the drill floor vertically move up and down through the pulley group; using four steel ropes of four transverse moving jennies all fixed on the ground to make the drill floor move left and right through the turning pulleys on the anchoring points and the drill floor. There are four extension and turning truckles on one side of the drill floor, near the steep slope. The anchored driller on the drill floor can regulate the angle of drilling hole on the horizontal and vertical surfaces. When constructing, using operation control button on the drill floor to control to lift the jenny and transverse moving jennies so as to move the drill floor to hole drilling position and make the drill floor closely adhere to the slope, and at the same time support up the supporting legs of the extension and turning truckles to press the drill floor in the hole position for drilling hole.
