Abstract: A platform for a tower of a wind turbine is provided, wherein the platform is adapted for a hanging arrangement inside the tower and includes at least one support for supporting the platform in a horizontal direction against a tower wall, wherein the support includes a foot section for contacting the tower wall, an abutment section attached to the platform, and a pretensioner, wherein the pretensioner preloads the foot section against the abutment section with a pretension force directed towards the tower wall, wherein the foot section is moveable at least sectionally towards the platform when a force directed towards the platform and acting on the foot section exceeds the pretension force.

Abstract: A liquid damper for a wind turbine tower includes a damper housing formed from a horizontal lower annulus, a horizontal upper annulus, an essentially cylindrical outer vertical wall and an essentially cylindrical inner vertical wall, wherein the outer diameter of the damper corresponds to the interior diameter of the tower; an operational volume of liquid contained in the damper; and an arrangement of vertical ribs mounted to a vertical wall of the damper. Further provided is a method of assembling a wind turbine.

Abstract: A leak containment arrangement for a fluid damper in a wind turbine tower includes a receptacle arranged below the fluid damper; a fluid guide arranged between the fluid damper and the receptacle, which fluid guide is arranged to receive fluid from a leak in the damper and to guide the leaked fluid into the receptacle; and a sensing means arranged to detect fluid in the receptacle. Further provided is a method of providing leak containment for a fluid damper in a wind turbine tower.

Abstract: A wind turbine includes a tower, a nacelle supported rotatably at a top portion of the tower, a main cable for transporting electrical energy produced in the nacelle to a bottom portion of the tower, and at least one auxiliary cable guided from the nacelle to an intermediate portion between the top and bottom portion and/or to the bottom portion of the tower, wherein the main cable includes a first loop, and the at least one auxiliary cable includes a second loop, and the first and second loops are configured for compensating, independently from each other, a movement of the respective cable due to rotation of the nacelle relative to the tower. Thus, movement of the auxiliary cables caused by yawing of the nacelle will not affect movement of the main cable.
