Abstract:
Method of transferring a person or a load between a vessel (20) and an access point (16) of an immovable offshore structure (10), wherein the access point is positioned higher than the vessel, the method comprising the step of establishing a connection by at least one flexible line (14) between the vessel and the offshore structure, which line is tensioned by driving the vessel to move away from the offshore structure without steering, and subsequently a transport member (22) is guided along the tensioned line to move between the vessel and the offshore structure.
Abstract:
The present invention relates to a method of transferring a load between a vessel and a wind turbine, wherein the wind turbine comprises a tower with an entrance above sea level; the tower comprises an accessory line, a tower body and a hollow boom; and the vessel carries a main line having a distal end for connection to the tower; the method comprising the steps of lowering the accessory line through the hollow boom connecting the main line at its distal end to the accessory line; hoisting the distal end of the main line using the accessory line; releasably connecting the distal end of the main line to the tower, the connection being releasable by remote control; using the vessel to ensure that the main line is taut at an angle a of less than 45° with the horizontal; and guiding a transport member along the taut main line to move the load between the vessel and the wind turbine. The invention also relates to a wind turbine.
Abstract:
The present invention relates to an apparatus for transferring an object from or to a marine transport vessel to or from a construction or vessel. The apparatus comprises a motive force generator; a motive force applicator operably linked to the motive force generator; and, in use of the apparatus, adapted to be operably linked to an object to which the motive force applicator applies a motive force; a fastening device for operably linking the motive force applicator to the object; a control mechanism; said control mechanism being formed and arranged so as to control the motive force generator and is operable to switch the operation of the motive force generator into an ascent or descent mode wherein the motive force generator acts upon the motive force applicator; and a measuring device operably linked to the control mechanism, said measuring device comprising one or more sensors and adapted to determine a distance between said measuring device and at least one point of a surface of a marine transport vessel from or to which said object is to be transferred wherein said apparatus further comprises one or more safety protocols and a parameter sensing means, said control mechanism being in communication with said parameter sensing means and responsive to feedback from said parameter sensing means, and adapted to initiate said one or more safety protocols.
Abstract:
The invention relates to a dampener pendulum (10) for dampening of movements arising from driving a load in a davit or similar lifting appliance, comprising an articulated connection (16) for transfer of pendulous movement between a holding part (12) and a pendulum part (14), where the holding part (12) is connected to said davit or the like and where the pendulum part (14) is connected to the load. The invention is characterised in that a first dampener block (18) is placed in said articulated connection (16), arranged to dampen said pendulous movement of the pendulum part (14), and that a second dampener block (20) is arranged to the holding part (12) set up to make possible, and to dampen, rotational movement of the holding part (12) and the pendulum part (14).
Abstract:
A container support assembly (38) for supporting a container (36) on a deck (56) of a sea vessel (50) includes a load distribution platform (82) configured to be fixedly attached to the deck (56) of the sea vessel (50) and a support frame (80) configured to receive the container (36) and be positionable over the load distribution platform (82). The support frame (80) is movable relative to the load distribution platform (82) between a raised position and a lowered position. In the raised position, the support frame (80) is spaced from the load distribution platform (82) so the position of the support frame (80) relative to the load distribution platform (82) is adjustable. In the lowered position, the support frame (80) engages the load distribution platform (82) so the load presented by the container (36) is distributed over the deck (56) of the sea vessel (50) via the load distribution platform (82). A method of replacing a component (40b) of an offshore wind turbine (10) using the container support assembly (38) is also disclosed.
Abstract:
An autonomous loading/unloading system and method for transferring material includes: a buoy (106) for releasing onto water; a messenger line (108) coupled to the buoy for being pulled; a carrier line loop (110) coupled to the messenger line for being pulled, where a payload (112) is coupled to the carrier loop for transferring the material to or from an unmanned ship; a fetch/release platform (218) to fetch or release the payload from or onto the water; a loading/unloading dock for the payload; a plurality of line guides (212) for guiding the carrier loop; and a platform-to-payload interconnect (306) for autonomous loading or unloading of the material from /to the payload.
Abstract:
Marine transfer apparatus for transferring a body (7) between a vessel (6) subjected to waves and an offshore structure (10). The apparatus comprises a transfer cable (1) on which the body (7) can ascend and descend in use. A structure coupling (4) connects a first end of the transfer cable (1) to an attachment point (12) provided on the offshore structure. A vessel coupling (5) connects a second end of the transfer cable (1) to the vessel (6). The transfer cable (1) comprises an elastically extendable region (3) for extending its length when taut between the structure (4) and vessel couplings (5) as the vessel moves in the waves (9). The vessel coupling (5) further comprises a reeling device (8) for reeling the transfer cable (1) between a taut state and a slack state when connected between the structure (4) and vessel couplings (5).
