    Abstract: A method of installing a rotor on a nacelle (44) on a wind turbine generally includes providing a rotor hub counterweight assembly (10, 10′) which are rotated and lifted from a downtower location to an uptower location at which wind turbine blades (50, 52, 54) are progressively attached and the counterweights (14, 16), (14′, 16′) are progressively removed. The rotor hub and counterweight assembly (10, 10′) for use when installing a rotor on a wind turbine (46) generally includes a rotor hub (12) having first, second and third flanges (18, 20, 22), a first counterweight (14, 14′), a second counterweight (16, 16′), and a lifting apparatus connecting member (26, 26′). A lifting apparatus connecting member (26) is configured with at least two connection points (60, 62) being configured for allowing at least two of three operations including installation, rotating and lifting the rotor hub (12), and removal of the lifting apparatus connecting member (26′).

    Abstract: A method of handling a wind turbine component (54) for assembly or maintenance, comprises coupling one or more unmanned air vehicles (20) with the wind turbine component (54) so that at least a portion of the weight of the wind turbine component (54) can be supported and lifted by the one or more unmanned air vehicles (20). The method further comprises coupling one or more cranes (50) with the wind turbine component (54) so that at least a portion of the weight of the wind turbine component (54) can be supported and lifted by the one or more cranes (50). The method further comprises controlling the one or more unmanned air vehicle (20) and crane (50) in coordination to lift the wind turbine component (54) and manoeuvre said component (54) with respect to a wind turbine (52).

    Abstract: A system for a wind park including: a control system in communication with a plurality of unmanned air vehicles, wherein the control system is configured to deploy one or more unmanned air vehicles during a triggering condition; and wherein the deployed unmanned air vehicles are guided towards an assigned wind turbine and to interact with a blade of that wind turbine in order to control oscillation of the blade. The invention also embraces a method for reducing blade oscillations of a wind turbine, comprising: monitoring for a triggering condition associated with the wind turbine; on detecting the triggering condition, deploying unmanned air vehicles towards a wind turbine and interacting with a blade of the wind turbine using the unmanned air to control oscillation of the blade. The invention therefore provides an efficient approach to controlling blade oscillations with minimal human operator involvement. Drones may be deployed automatically once suitable conditions are detected and may automatically engage with the blades, either by contacting those blades physically, or by interacting with the blades in close proximity, in order to disrupt airflow around the blades thereby reducing oscillations.
