Title (EN) METHOD AND APPARATUS OF PERFORMING MAINTENANCE ON A WIND TURBINE COMPONENT
(FR) PROCÉDÉ ET APPAREIL DE RÉALISATION D'OPÉRATIONS DE MAINTENANCE SUR UN ÉLÉMENT D'ÉOLIENNE
Abstract:
(EN) A method of performing maintenance on a wind turbine component (18, 22, 24) of a wind turbine (10) having an integrated lifting apparatus (40). The method includes lifting a first temporary support (104) using the integrated lifting apparatus (40), coupling the first temporary support (104) to the nacelle (12) or the hub (16) and the integrated lifting apparatus (40), removing the wind turbine component (18, 22, 24) using the integrated lifting apparatus (40) and the first temporary support (104) in combination. The method may further include installing a replacement wind turbine component (18, 22, 24) using at least a part of the integrated lifting apparatus (40) and the first temporary support (104) in combination, decoupling the first temporary support (104) from the nacelle (12) or the hub (16) and the integrated lifting apparatus (40), and removing the first temporary support (104) from the wind turbine (10) using the integrated lifting apparatus (40). A system for performing maintenance on a wind turbine component (18, 22, 24) is also disclosed.
(FR) L'invention concerne un procédé de réalisation d'opérations de maintenance sur un élément d'éolienne (18, 22, 24) d'une éolienne (10) comprenant un appareil de levage intégré (40). Le procédé comprend le levage d'un premier support temporaire (104) au moyen de l'appareil de levage intégré (40), l'accouplement du premier support temporaire (104) à la nacelle (12) ou au moyeu (16) et à l'appareil de levage intégré (40), le retrait de l'élément d'éolienne (18, 22, 24) au moyen de l'appareil de levage intégré (40) et du premier support temporaire (104) en combinaison. Le procédé peut en outre comprendre l'installation d'un élément d'éolienne de remplacement (18, 22, 24) au moyen d'au moins une partie de l'appareil de levage intégré (40) et du premier support temporaire (104) en combinaison, le découplage du premier support temporaire (104) de la nacelle (12) ou du moyeu (16) et de l'appareil de levage intégré (40), et le retrait du premier support temporaire (104) de l'éolienne (10) au moyen de l'appareil de levage intégré (40). L'invention concerne également un système permettant de réaliser des opérations de maintenance sur un élément d'éolienne (18, 22, 24).
