Abstract: Provided is a method for moving an object between a platform of a wind turbine and a deck of a vessel, wherein the platform is located at a tower the wind turbine, wherein the object is moved vertically by a hoist coupled between the object and at least one fixation site the wind turbine located above the platform and the deck, wherein the object is deflected radially from the tower by a puller coupled between the object and the vessel.

Abstract: The invention is directed to embodiments of wind turbine arrangements. One wind turbine arrangement includes an inflatable component disposed within a hollow section of a wind turbine blade, wherein the inflatable component is a platform usable during service and/or installation of a wind turbine module, wherein the inflatable component includes an inflation structure with an air tight shell, wherein the air tight shell includes an inner shell and an outer shell surrounding the inner shell, and wherein the outer shell includes a material that protects against puncture of the inner shell. Another wind turbine arrangement includes a wind turbine blade; an inflatable platform positioned in the wind turbine blade; and an inflatable outer pressure ring that surrounds the platform, wherein the outer pressure ring, when inflated, fixes the platform in the wind turbine blade by generating a normal friction force between the platform and the wind turbine blade.

Abstract: Provided is an inflatable component usable during service and/or in-stallation of a wind turbine module, including an inflation structure with an air tight shell and a sealable package in the inflation structure for ingress or discharge of air into or from the air tight shell for inflating or deflating struc-ture. The inflation structure is dimensioned to provide a thermal and/or physical barrier in respect of external fluids and/or physical objects or particles acting upon the infla-tion structure in case the inflation structure is inflated and inserted in a hollow section of the wind turbine module. Further provided is a wind tur-bine arrangement including such an inflatable component and also to a servicing or installation method of a wind turbine module by using the inflatable component.

Abstract: Provided is a method for repairing a root of a rotor blade of a wind turbine, the root including several bores for receiving a bolt and extending form the root front surface into the blade, wherein at least a part of the front surface blade material surrounding the bore is removed using a removing tool and that at least one shim plate is attached to the processed front surface surrounding the bore.
