Abstract: The present invention relates to a system and a method for weighing a section of a structure (1). The system comprises at least one hydraulic weight sensor device (3), adapted to be placed in at least one slot (2) under the section, a pressure sensor (7) for measuring the pressure in the at least one weight sensor device (3), and a hydraulic system comprising at least one pump unit (5) and at least one valve unit (6) for pumping hydraulic fluid to and from the at least one hydraulic weight sensor device (3) through a hydraulic line (4). The system further comprises a distance sensor (10) for measuring the height of the slot (2), a control circuit device (20) for calculating the weight of the section based on measured data received from the pressure sensor (7), and for balancing the section on the basis of the measured data received from the pressure sensor (7) and the distance sensor (10) by controlling the pump unit (5) and the valve unit (6).

Abstract: The invention pertains to a heave compensation system for continuous operation on a floating vessel (1), the system comprising at least one buoyant body (11), at least one lever arm (10) for arrangement in a generally horizontal plane, pivotal means capable of limited rotation about a horizontal axis and arranged to connect one end of the lever arm to the buoyant body (11), at least one hinge (13) connected to an intermediate point on the lever arm (10) and capable of allowing limited rotational movement of the lever arm (10) in a vertical plane, means to attach the hinge (13) to the floating vessel (1), and at least one counterbalance weight (12) connected to the lever arm (10) on the side of the hinge (13) away from the buoyant body (11), whereby the inertia of the counterbalance weight (12) resists heave movements of the buoyant body (11) relative to the floating vessel.

Abstract: A device for repairing damages or providing branchings on pipes, especially in existing underwater pipe installations, comprises a cylindrical, longitudinally divided muff (1) which is dimensioned to be placed around and clamped to the topical pipe (4) by a clamping means (6), a sealing means (18) being provided between the muff (1) and the surface of the pipe (4). At least one of the muff members (2, 3) is composed of a strong outer layer (10) and a less strong inner layer (11) which layers are joined so as to form an intermediate closed volume (14 and 15), said muff member (2 or 3) being provided with a means (17) for supplying a hydraulic pressure medium (19) to said volume, so that the volume when pressurized expands and the inner layer (11) and the sealing means (18) thereby are pressed to seating engagement with the adjacent surface of the pipe (4).

Abstract: Method for increasing the distance between two faces, inserting into a space between the two faces a diaphragm power jack, the shape of which being adapted to the shape of the space, the diaphragm power jack comprising two abutting sheets being sealingly bonded along the entire circumference, a pipe penetrating the bonded, injecting a pressurized fluid through the pipe to the interface between the two sheets thereby forcing the sheets apart whereby substantially all the energy from the pressurized fluid being converted to forces perpendicularly to the sheets.
