Abstract: An offshore wind turbine including a tower, a transition piece and a lifting apparatus for operating a lift inside the wind turbine is provided. The tower includes an inner platform at the bottom end of the tower. The transition piece includes a hang-off platform. The lifting apparatus includes a plurality of wires, a plurality of tensioners, one or more brackets attached to the inner platform and movable between at least a first operative configuration in which the plurality of tensioners are attached to the one or more brackets and the lift is movable from the first station at the inner platform towards the upper end of the tower, a second retracted configuration in which one or more brackets allows the lift to move between the first and the second station, the plurality of tensioners being attached to the hang-off platform.

Abstract: Provided is a method for manufacturing a wind turbine, the wind turbine including a high voltage cable configured to connect a generator of the wind turbine with a switch gear of the wind turbine, the method: a) guiding the high voltage cable inside a tower of the wind turbine from an upper part of the tower to a lower part of the tower, and b) returning the high voltage cable at the lower part of the tower up again. Returning the high voltage cable at the lower part of the tower up again simplifies storing an additional length of the high voltage cable inside the tower.

Abstract: It is described a method of installing a power cable (5) in a wind turbine tower (1), in particular for transportation, the method comprising: arranging a section (5) of the cable within the tower, the section having a length, in particular by at least an upper excess cable portion, greater than the tower height (h), by forming a cable loop (27, 33) within the tower (1), wherein an angle enclosed between a normal (34) of a cable loop plane and the longitudinal direction (4) of the tower (1) is between 70° and 110°.

Abstract: A wind turbine including: a tower including a wall portion and a flange, a platform, and a stay suspending the platform from the wall portion, wherein the stay is pivotably connected to the platform and/or the wall portion, and wherein a diameter of the platform is smaller than an inner diameter of the tower at the flange, is provided. - The platform can be mounted inside a tower of the wind turbine even when the platform has a diameter that is significantly smaller than an inner tower diameter.

Abstract: A method for manufacturing a wind turbine, the method includes the steps of: a) manufacturing a bottom module, the bottom module including at least one first platform; b) manufacturing a top module, the top module includes at least one second platform; and c) assembling the bottom module and the top module to form a platform assembly is provided. Manufacturing the platform assembly from two separate modules allows to manufacture a higher platform assembly.
