Abstract: Providing energy to an energy consuming piece of equipment and/or tool during offshore operations. Use is made of a crane including a substructure, a boom mounted on the substructure, one or more hoist winches and cables, as well as an object suspension device suspended from the boom by the cables. A piece of equipment or tool is suspended from the object suspension device. An energy storage unit is provided on the object suspension device and has an input connector. The boom may be provided with an output connector of an energy charging unit and in a lower supply position of the object suspension device it is disconnected from the input connector of the energy storage unit. The piece of equipment or tool is then run on energy supplied by the energy storage unit. Moving the object suspension device to a charging position thereof by employing the hoist assembly of the crane brings the input connector of the energy storage unit in close proximity of the output connector of the energy charging unit which are then interconnected to charge the energy storage unit from a separate energy source.

Abstract: A marine pipelaying friction clamp device for frictionally retaining an offshore subsea pipeline to be launched into the sea includes a frame which includes a main frame structure that is adapted to be supported by the pipelaying vessel. The frame supports multiple annular arrays of clamping units adapted to simultaneously engage separate portions of the pipeline. The frame further includes one or more mobile subframes for one or more of said annular arrays of clamping units. Each of said one or more mobile subframes is movably supported by the main frame structure so as to be mobile relative to said main frame structure in said longitudinal direction of the clamp device, and each of said one or more mobile subframes is supported by a spring assembly.

Abstract: A marine pipeline installation vessel and a method are provided for laying an offshore rigid pipeline in the sea, the vessel at least being adapted to carry out the rigid reel lay method. The vessel includes at least one vertical storage reel for the storage of a spooled rigid pipeline. A left and right reel support structure are provided to support the weight of the at least one storage reel. The left and right support structures are embodied to form a pivoting structure allowing an angular adjustment of the horizontal reel axis about a vertical axis to alter the angular position of the at least one storage reel.

Abstract: A pile upending and holding system includes a support assembly configured to be mounted on the vessel and to provide compensation for wave-induced motion of the vessel to maintain a predetermined X-Y location of the pile holder independent of said motion, and a pile holder mounted on the support assembly to be tillable about a substantially horizontal tilt axis. The pile holder includes a lower ring and an upper ring, and a pile holder frame supporting the lower ring and upper ring, the upper ring longitudinally spaced from the lower ring. Each of the rings include pile engaging devices distributed about the circumference thereof, each pile engaging device being adapted to engage an exterior of the pile extending through the lower and upper ring. Each of the lower ring and upper ring includes a ring base fixed to the pile holder frame and one or more movable jaws, movable between a closed position for holding and guiding the pile and an opened position for entry of the pile. The pile holder is provided, below the lower ring thereof, with a pile foot end support for engaging a longitudinal end of the pile to limit longitudinal movement thereof.

Abstract: A tensioner pad assembly is adapted to be mounted on an endless track of a tensioner to frictionally clamp an elongated product supported and moved by the tensioner. The pad assembly includes a carrier member and a pair of gripping members, which gripping members can with their carrier member mating surfaces be mounted in multiple discrete gripping positions on gripping member mating surfaces of the carrier member. The mating surfaces form interlocking structures adapted to transfer a squeeze force from the carrier member to the gripping members. The interlocking structures provided on the carrier member define the multiple discrete gripping positions. The gripping member mating surfaces extend at an angle relative to each other, such that the multiple discrete gripping positions differ in their distance to the base portion as well as in their distance to the imaginary plane of the carrier member.

Abstract: A method is provided for installing a pipeline on the seabed from a marine pipelaying vessel, including initiation, pipelaying, and abandonment of the pipeline. An embodiment of the abandonment of the pipeline includes halting pipelaying and engaging a hang-off clamp with the pipeline at a position below one or more tensioners, transferring the weight onto the hang-off clamp and holding the seagoing pipeline in the firing line, severing the pipeline, connecting the initiation cable to the lower end of the pipeline held by the one or more tensioners, transferring pipeline tension onto the initiation cable, releasing the one or more tensioners, so that a section of the pipeline is held in the firing line between the pipeline diverter and the initiation cable, vacating the firing line by at least displacing both the pipeline diverter and the initiation cable sheave and thereby displacing said section of the pipeline from the firing line, arranging the A&R cable in the firing line, connecting the A&R cable to the upper end of the seagoing pipeline held in the firing line, releasing the hang-off clamp, and operating the A&R winch and thereby lowering the pipeline onto the seabed.
