摘要： The present invention relates to a partly assembled structure in the form of a structure comprising a wind turbine tower, a nacelle arranged thereon and a vibration damper attached to the nacelle for damping vibrations of the combined wind turbine tower and nacelle within a selected frequency range, wherein the vibration damper is operatively connected to a main shaft of the nacelle, or wherein the vibration damper is attached to the nacelle via a nacelle transportation interface. The present invention further relates to a method of constructing a wind turbine and a method for damping Vortex induced vibrations of the combined wind turbine tower and nacelle within the selected frequency range.
