Title (EN) METHOD OF BUILDING AN OFFSHORE WINDMILL
(FR) PROCÉDÉ DE CONSTRUCTION D'UNE ÉOLIENNE EN MER
Abstract:
(EN) The invention relates to a method of building an offshore windmill (100) on a windmill pedestal (50) that is located offshore. The method comprises: i) providing a floating vessel (900) comprising a 3D-heave-compensated crane (910) on a deck (901) thereof; ii) providing at least one offshore windmill assembly (110, 120, 130) and a lifting jack (90), wherein the offshore windmill assembly comprises a windmill generator (120), a plurality of wind- mill blades (130, 130-1..130-3) and at least two windmill column parts (110, 110-1..110-3) for forming a windmill column at a later stage, wherein the lifting jack (90) is configured for receiving the windmill column (110-1..110-3) in a receiving region thereof; iii) moving said floating vessel (900), the lifting jack (90) and the at least one offshore windmill assembly (110, 120, 130) in proximity of the windmill pedestal (50); iv) placing the lifting jack (90) directly on the windmill pedestal (50) using the 3D-heave-compensated crane (910) and fixing the lifting jack (90) to the windmill pedestal (50) such that it can be later removed, and wherein the lifting jack (90) is fixed to the windmill pedestal (50) such that the windmill column (110-1..110-3) can be placed within the receiving region directly on the windmill pedestal (50); v) installing the windmill generator (120) using the 3D-heave-compensated crane (910); vi) partially erecting the windmill column (110-1..110-3) on the windmill pedestal (50) using the 3D-heave-compensated crane (910) and the lifting jack (90); vii) installing the windmill blades (130, 130-1..130-3) on the windmill generator (120) using the 3D-heave-compensated crane (910) at a stage where the windmill column (110-1..110-3) has been partially erected; viii) fully erecting the windmill column (110-1..110-3) on the windmill pedestal (50) using at least the lifting jack (90), and ix) removing the lifting jack (90) from the windmill pedestal (50) using the 3D-heave-compensated crane (910). The invention provides for a further improved retrofit method of building offshore windmills.
(FR) L'invention concerne un procédé de construction d'une éolienne (100) sur un socle d'éolienne (50) qui est situé en mer. Le procédé comprend : i) la fourniture d'un navire flottant (900) comprenant une grue à compensation de pilonnement 3D (910) sur un pont (901) de celui-ci; ii) la fourniture d'au moins un ensemble éolienne (110, 120, 130) et un vérin de levage (90), l'ensemble éolienne comprenant un générateur d'éolienne (120), une pluralité de pales d'éolienne (130, 130-1. 130-3) et au moins deux parties de colonne d'éolienne (110, 110-1. 110-3) pour former une colonne d'éolienne à étage supérieur, le vérin de levage (90) étant configuré pour recevoir la colonne d'éolienne (110-1. 110-3) dans une région de réception de celui-ci; iii) déplacer le navire flottant (900), le vérin de levage (90) et l'un ou les ensembles d'éoliennes (110, 120, 130) à proximité du socle d'éolienne (50); iv) placer le vérin de levage (90) directement sur le socle d'éolienne (50) à l'aide de la grue à compensation de pilonnement 3D (910) et à fixer le vérin de levage (90) au socle d'éolienne (50) de telle sorte qu'il peut être retiré ultérieurement, et le vérin de levage (90) étant fixé au socle d'éolienne (50) de telle sorte que la colonne d'éolienne (110-1. 110-3) peut être placé à l'intérieur de la région de réception directement sur le socle d'éolienne (50); v) installer le générateur d'éolienne (120) à l'aide de la grue à compensation de pilonnement 3D (910); vi) le montage partiel de la colonne d'éolienne (110-1. 110-3) sur le socle d'éolienne (50) à l'aide de la grue à compensation de pilonnement 3D (910) et du vérin de levage (90); vii) l'installation des pales d'éolienne (130, 130-1. 130-3) sur le générateur d'éolienne (120) à l'aide de la grue à compensation de pilonnement 3D (910) au niveau d'un étage où la colonne d'éolienne (110-1. 110-3) a été partiellement érigée; viii) l'érection complète de la colonne d'éolienne (110-1. 110-3) sur le socle d'éolienne (50) à l'aide d'au moins du vérin de levage (90), et ix) retirer le vérin de levage (90) du socle d'éolienne (50) à l'aide de la grue à compensation de pilonnement 3D (910). L'invention concerne un nouveau procédé de rattrapage amélioré pour construire des éoliennes en mer.
