摘要： A method for handling of an offshore wind turbine component includes using a vessel having a hull on which a motion compensating crane is mounted. The crane includes a main boom; a main boom luffing assembly; a mobile hoist cable suspension member; and a hoist winch and a hoist cable driven by the hoist winch. An object suspension device is suspended from the hoist cable. The mobile hoist cable suspension member is supported by a motion compensating support device that is fitted to the tip end of the main boom, the motion compensating support device including one or more motor powered motion displacement actuator assemblies and a motion compensating support device controller. The method includes connecting the offshore wind turbine component to the object suspension device; and operating the motion compensating support device to provide motion compensation in at least one direction of the object suspension device and the connected offshore wind turbine component. The crane is provided with one or more nacelle position detectors that are configured and operated to sense at least one of actual position and actual motion of the nacelle or of one or more components in or on the nacelle, and the one or more nacelle position detectors are linked to the motion compensating support device controller.

摘要： A method for installation of a pile adapted to support an offshore wind turbine in which the piles are transported horizontally, positioned in a pile holder, rotated to a vertical orientation while being held by the pile holder, and subsequently lowered into the water while being held by the pile holder. The installation vessel is in a floating condition, and the pile holder is compensated for wave-induced motion of the vessel to maintain a predetermined X-Y location independent of the wave-induced motion of the vessel. A pile holding system, a pile holder, and a vessel comprising a pile holding system are also disclosed.

摘要： An offshore drilling system includes a drilling tower, a tubular string hoisting device with a crown block and a travelling block suspended from the crown block in a multiple fall arrangement. A heave compensation system is adapted to provide heave compensation of the travelling block. The heave compensation system includes a hydraulic sheave compensator. The system further includes a mobile working deck which is movable with respect to the drilling tower within a motion range including a heave compensation motion range. The heave compensation system is further adapted to provide heave compensation of the mobile working deck by a hydraulic deck compensator, which is hydraulically connected via a hydraulic conduit to the hydraulic sheave compensator, such that in operation the deck compensator moves synchronously with the sheave compensator of the heave compensation system.

摘要： The invention relates to a drilling vessel comprising a drilling tower and a tubular string support structure for supporting a tubular string in the firing line of the drilling tower. The tubular string support structure has two parallel rails and two carts supported by those rails. Both carts have a hanger body with a central passage for supporting a tubular, and each cart can be moved between a central support position for supporting a tubular in the firing line, and a secondary position adjacent the central support position. When both carts are located in their secondary position, the carts are located on opposite sides of the firing line, such that between the carts there is a passage for passing through large objects along the firing line.

摘要： A Crane boom segment is provided for assembly of a crane boom by interconnection of multiple crane boom segments from a transport configuration to an operational configuration. The crane boom segment includes a first and second planar latticed truss, each with two chords between which permanent lacing elements extend. Both chords of each planar latticed truss include segment connection parts at their head ends allowing crane boom segments to be connected to each other in series, and in the operational configuration the first and second planar latticed trusses are provided at opposite sides of the longitudinal axis of the crane boom segment. A crane boom segment further includes a first and second lattice web, each lattice web connectable to one of the chords of the first planar latticed truss and one of the chords of the second planar latticed truss. A modular crane includes a travelling base frame which allows for travel of said crane over a surface, and a crane boom assembled from crane boom segments, one end of the crane boom being hingedly connected about a substantially horizontal pivot axis to said travelling base frame.

摘要： 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.
