Abstract[English]
In a first example there is provided a method of servicing a wind turbine rotor blade. The blade comprises an outer shell defining an interior cavity, and the rotor blade is part of a rotor connected to a wind turbine. The method comprises arranging the rotor such that the 5 blade is in a first orientation, installing a work platform in the interior cavity of the blade when the blade is in the first orientation, and subsequently arranging the blade in a second orientation. The method further comprises using the work platform, when the blade is in the second orientation, to support a technician performing a service operation on the blade.

Dans un premier exemple, l'invention concerne un procédé d'entretien d'une pale de rotor d'éolienne. La pale comprend une enveloppe extérieure délimitant une cavité intérieure, et la pale de rotor fait partie d'un rotor relié à une éolienne. Le procédé consiste à agencer le rotor de telle sorte que la pale soit dans une première orientation, installer une plate-forme de travail dans la cavité intérieure de la pale lorsque la pale est dans la première orientation, puis à disposer la pale dans une seconde orientation. Le procédé consiste en outre à utiliser la plate-forme de travail, lorsque la pale est dans la seconde orientation, pour supporter un technicien effectuant une opération d'entretien sur la pale.
