Abstract[English]
A method of filling a ballast tank (30) positioned within an interior of a wind turbine blade (20), the method comprising the steps of: providing a wind turbine blade (20), the wind turbine blade having a ballast tank (30) within an interior (42) of the blade; determining the location of the 5 ballast tank (30) in the blade (20); applying a visible position identifier (60) to an exterior surface (55) of the blade at a location corresponding to the position of the ballast tank (20); forming a hole (50) through the exterior surface (55) of the blade and into the ballast tank (30), at the location of the position identifier (60); introducing ballast material (48) through the hole (50) into the ballast tank (30)[French]
L'invention concerne un procédé de remplissage d'un réservoir de ballast (30) positionné à l'intérieur d'une pale d'éolienne (20). Ledit procédé comprend les étapes consistant à : fournir une pale d'éolienne (20) présentant un réservoir de ballast (30) à l'intérieur (42) de la pale ; déterminer l'emplacement du réservoir de ballast (30) dans la pale (20) ; appliquer un identifiant de position visible (60) à une surface externe (55) de la pale à un emplacement correspondant à la position du réservoir de ballast (20) ; former un trou (50) à travers la surface externe (55) de la pale et dans le réservoir de ballast (30), à l'emplacement de l'identifiant de position (60) ; et introduire un matériau de ballast (48) dans le réservoir de ballast (30) à travers le trou (50).
