摘要： The offshore jack-up has a hull and a plurality of moveable legs engageable with the seafloor. The offshore jack-up is arranged to move the legs with respect to the hull to position the hull out of the water. The method comprises moving at least a portion of a vessel underneath the hull of the offshore jack-up or within a cut-out of the hull when the hull is positioned out of the water and the legs engage the seafloor. A stabilizing mechanism mounted on the jack-up is engaged against the vessel. The stabilizing mechanism is pushed down on the vessel to increase the buoyant force acting on the vessel.

摘要： A rotor hub for a wind turbine which can be configured between an in use or ‘operational’ configuration and a transportation configuration. In the transportation configuration the rotor hub has a reduced external size compared to when it is in the operational configuration. The rotor hub comprises a generally hollow hub body having a first end and a second end spaced along a hub rotational axis, wherein the first end defines a rotor connection flange configured to connect the rotor hub to a main shaft, and wherein a second end defines a nose region of the hub. The hub also defines at least one blade aperture defined between the first end and the second end, a blade bearing associated with the or each blade aperture, and a pitch actuator associated with the blade bearing. In the operational configuration a portion of the pitch actuator protrudes from the nose region of the hub body by a first distance, whereas in the transport configuration the portion of the pitch actuator protrudes from the nose region of the hub body by a lesser extent than when in the operational configuration. Therefore it will be appreciated that the pitch actuator is energised to change the extent to which the pitch actuator protrudes through the nose region of the hub body.

摘要： A new method for installing one or more electric cables (60) in a wind turbine tower section (100) is provided. The method comprises providing the wind turbine tower section (100) in a substantially horizontal orientation and installing a zip line (20) inside the wind turbine tower section (100), between a first end (120) and a second end (130) of the wind turbine tower section (100). The method further comprises coupling a second end of the electric cables (60) to the zip line (20) at a location near the first end of the wind turbine tower section (100), drawing the second end of the electric cables (60) through the wind turbine tower section (100) along the zip line (20), decoupling the second end of the electric cables (60) from the zip line (20), and removing the zip line (20) from the wind turbine tower section (100). The method further comprises anchoring a first end of the electric cables (60) to the wind turbine tower section (100), at a location adjacent the first end of the wind turbine tower section (100), and anchoring the second end of the electric cables (60) to the wind turbine tower section (100), at a location adjacent the second end of the wind turbine tower section (100).

摘要： A deployed L-shaped rack structure interengaged with a self-elevating vessel is used for supporting a feeder transport vessel, such as an ocean or sea barge, to eliminate relative motion or movement between the vessels. Some of the proposed rack structures are movable between a stowed position and a deployed position. The method of use for the movable rack structures includes the self-elevating vessel arriving at a predetermined location, elevating the hull of the self-elevating to a suitable height above the sea surface at a desired still water line (SWL) to create an air gap, and then deploying the rack structure. A feeder transport vessel, with its cargo and/or components, can then be floated over the deployed rack structure. The self-elevating vessel then uses its jacking system including a plurality of legs supported on the seabed to raise the feeder transport vessel and its cargo and/or components to a desired height above the SWL. From this position relative motion between the self-elevating vessel and transport vessel is eliminated so that the self-elevating vessel lifting device, such as a crane, can be more safely used to install energy components, such as wind turbine components. A bottom supported tower/column section could also be assembled and installed in seabed using the self-elevating vessel and rack structure along with the lifting device. A fixed rack structure system and its method can also be advantageously used with a self-elevating vessel. The systems and methods could be used in reversing the method or steps for deinstallation of the energy components installed in the sea.
