LIFTING SYSTEM FOR ERECTING, MAINTAINING OR DISMANTLING A FLOATING WIND TURBINE
The invention relates to a lifting system (1) for erecting, maintaining or dismantling a floating wind turbine (4), which comprises: - a tower (11) comprising at least two elements (11A-11D) which can be telescoped together such that it can assume at least a retracted position, and a deployed position; - and a crane (12) mounted on an upper element (11A), this crane being mobile in rotation about a vertical axis (X1) of the system. Such a system, mounted on a dock, can be used in the deployed position to work on a wind turbine, and, in the retracted position, as a harbour crane.
The invention relates to a hoisting system (15, 18) for lifting a blade (11 A) for a wind turbine (2), comprising a derrick (80) that is mounted at the top of a telescopic pole and provided to compensate (R) a relative movement (M) between the wind turbine and the hoisting system.
