Title: VORTEX-SHEDDING-ARRANGEMENT
Abstract:
The invention relates to a Vortex-shedding-arrangement, which is prepared to be arranged on a tower of a wind turbine. The invention even relates to a tower, which is equipped with the Vortex-shedding-arrangement and to a method to equip the tower with the Vortex-shedding-arrangement. The Vortex-shedding-arrangement according to the invention (2) is arranged and prepared to be connected to a surface of a tower (1). The Vortex-shedding-arrangement (2) is prepared to reduce Vortex-induced-vibrations (VIV), acting on the tower (1) and its structure, during the tower-transportation. The vortex shedding arrangement (2) comprises vortex shedding elements (VSE) and at least one shrink foil (SF1, SF2). The at least one shrink foil (SF1, SF2) is prepared to fix and to position the vortex shedding elements (VSE) at specific positions at the tower surface by heat applied to the shrink foil.
