Abstract: A method of handling an auxiliary nacelle unit (24, 26) of a wind turbine (10) includes assembling a temporary hoist (52) on a main nacelle unit (22) by pivotally connecting a boom (64) to the main nacelle unit (22), pivotally connecting a mast (66) to the main nacelle unit (22), connecting the actuator (68) between the mast (66) and the boom (64), and routing a hoist cable (56) from a winch (54) to a hoist cable locator (60). The method further includes connecting the hoist cable (56) to an auxiliary nacelle unit (24, 26), activating the winch (54) to move the auxiliary nacelle unit (24, 26) from a first position to a second position, and activating the actuator (68) to move the boom (64) between the retracted position and the extend position. A lifting arrangement (50) for handling an auxiliary nacelle unit (24, 26) of a wind turbine (10) is also disclosed.

Abstract: A system for the automated lifting of a wind turbine mounted on a transition piece with a tubular tower, nacelle and corresponding blades thereof. A lifting triangle that passes, through a retractable bolt, through the bottom ends of columns of the transition piece, the joining thereof being completed with the hydraulic presses, ascends and descends in direct contact with the three masts. The masts are mounted on bases disposed on the ground and anchored to foundations. Cables extend from a winch, pass through pulleys at the top of the mast and connect to a fixed pulley block and to a moveable pulley block of the triangle.

Abstract: Described is a device for offshore arranging of a wind turbine or components thereof on a foundation present at sea. The device includes an elongate superstructure connected releasably to the foundation and extending between a lower surface and an upper surface thereof in the vertical direction from the foundation. The superstructure has an internal space which is accessible to a tower section of the wind turbine and in which the tower section can be received. Further present is a horizontally displaceable supply structure for a tower section. The supply structure is configured to move a tower section coupled thereto from outside the internal space into the internal space by a horizontal displacement. An engaging structure, received for vertical displacement in the internal space, is configured to lift an engaged tower section in the internal space by a vertical displacement, whereby sufficient space is created under the relevant tower section for receiving another, underlying tower section in the internal space.
