Method of lifting a wind turbine part (58) at a wind turbine site (1, 2), the method includes: providing a lifting apparatus (60) and a wind turbine part (58) to be lifted; providing a shield (40); providing manipulation equipment (45) associated with said shield (40); and suspending said part (58) from said lifting apparatus (60); moving said part (58) by means of said lifting apparatus (68); the method further including holding said shield (40) proximate and upwind of said part (58) being lifted by means of said manipulation equipment (45). The shield (40) may be held proximate the part (58) being lifted such that it acts to reduce the ambient wind force incident on the part (58). Preferably the method may be implemented such that wind speed conditions (w) at the part (58) being lifted are lower than ambient wind conditions (W) at said site (1, 2). A kite-flying apparatus includes a power kite (40) and associated manipulation equipment (45), including cables (42, 44) at least one steering winch (28, 29), the winch being received in a winching module (26) including a ballast receiving fitment and a winch control system.

A method for computer-implemented identifying an unauthorized access to a wind farm is provided by obtaining environmental and operational data of the wind farm from a repository, which include technical data and organizational data of the wind farm indicating tasks to be dealt with in the wind farm in the future. Based on the environmental and operational data, for a predetermined time interval, a prediction of the operation and/or states of the wind farm is determined by a trained data driven mode. The trained data driven model provides a prediction of the operation and/or states of the wind farm as a digital output. The prediction is compared to operational conditions of the wind farm resulting from current or past user machine interactions of a user. An unauthorized access is identified in case of a predetermined deviation of the obtained operational conditions from the prediction of the operation and/or states of the wind farm.

A surface treatment vehicle for manufacturing a wind turbine blade is provided, the vehicle including: a transportation unit for locomotion of the vehicle, and a filling unit for applying a filler material on a surface of the blade, wherein the filling unit includes: a dispensing head for dispensing the filler material, the dispensing head being moveably attached to the transportation unit, and a tank for storing the filler material, the tank being attached to the transportation unit and fluidly connected to the dispensing head. Having the surface treatment vehicle with the filling unit allows an easier, faster, safer and more efficient manufacturing of a wind turbine blade.
