Supporting device

A device for supporting equipment (4, 5) on a floating structure, said equipment preferably extending between the structure (1) and the ocean floor (3), comprising at least two hydraulic cylinders (9a, 9b) which are arranged between the structure and the equipment and which are connected to a source of hydraulic pressure fluid, characterized in that it further comprises a valve means (17) which for each of the hydraulic cylinders (9a, 9b) is connected to the respective hydraulic cylinder (9a, 9b) on the piston rod side of its piston (11a, 11b) via a first conduit (16a, 16b) and via a second conduit (18a, 18b) is connected with the hydraulic cylinder (9a, 9b) on the opposite side of the piston (11a), the valve means (17) being arranged to connect said first and second conduits (16a, 16b;

• 18a, 18b) for each hydraulic cylinder (9a, 9b) under normal pressure conditions and under deviant pressure conditions in one hydraulic cylinder (9 a, 9b) to break the connection between said first and second conduits (16a, 16b;
• 18a, 18b) for the remaining hydraulic cylinders (9a, 9b) and connect the first conduits (16a, 16b) for these with the first and second conduits (16a, 16b;
• 18a, 18b) of the deviant hydraulic cylinder (9a, 9b), and in that the area of the piston (11a, 11b) of each hydraulic cylinder (9a, 9b) on the piston rod side is equal to the piston area (A) on the opposite side divided by the number of hydraulic cylinders (9a, 9b) connected to the valve means (17).
