    Abstract: Lifting yoke (10) configured for supporting a load (1) while suspended from a bearing wire (16); the yoke (10) comprising a frame (15) extending about a bearing axis (17); said yoke (10) additionally comprising an orientation adjustment arrangement comprising at least two thrusters (20) associated with an orientation control system (51); said thrusters (20) being controllable to adjust and/or stabilise the angular orientation of said yoke (10) in a horizontal plane; characterised in that said load (10) is an element of a wind turbine; wherein said yoke includes at least two steering arms (30) each of which extends in mutually opposite directions away from said bearing axis (16) and beyond said yoke frame (15); and wherein each of said at least two thrusters (20) is provided on a respective steering arm (30) of said yoke (10); wherein each said steering arm (30) has a yoke interface at a proximal end (43) thereof, and wherein a said thruster (20) is arranged on said arm (30) towards a distal end (44) thereof. A method of lifting a load by means of the yoke, or a method of bringing a yoke into an orientation for a load to be lifted are also disclosed.

    Abstract: A wind turbine tower evacuation tool (10) is provided comprising an object end (20) for attachment to an object (500) or a person (555) and a roller end (30, 301, 302, 303) configured for connection to a surface of a wind turbine tower (110) by magnetic attraction. 5 The roller end (30, 301, 302, 303) comprises at least one magnet body (33) arranged for rotation around a rotational axis of the roller end (30, 301, 302, 303). The wind turbine tower evacuation tool (10) further comprises a rope element (11) connecting the object end (20) to the roller end (30, 301, 302, 303). 10 [Fig. 2 to accompany abstract]

    Abstract: An airborne wind energy system (100) and a method for controlling such an airborne wind energy system (100), which comprises a kite (102) connected by a number of steering lines (301) to a control box (300) and coupled via a cable (105) to a winch system on a ground station (104). The control method comprises detecting an error signal from a component of the airborne wind energy system (100), wherein the error signal is set by a detection of a breaking of the cable (105) and/or a fault on the winch system controlling the extraction and retraction of the cable (105). The control method further comprises controlling the movement of the control box (300) according to a landing mode, and activating a safety device connected to the control box (300).

    Abstract: A wind turbine comprising at least two separate units assembled to form a nacelle connected to a wind turbine tower. A first of said two units houses a rotor-supporting assembly and a generator. To enable a large degree of flexibility and the ability to reconfigure, a second of said two units houses an electrolysis cell stack powered by the generator.

    Abstract: A payload coupler with a position control device for controlling a position of the payload coupler when suspended from a lower end of a line for attachment at an upper end thereof to a lifting device. The payload coupler includes a payload attachment means and at least two propulsors. The payload attachment means couples to and/or decouples from a payload and is arranged to directly couple the payload coupler to a payload. The propulsors are configured to generate resultant propulsion forces which are non-parallel and having at least a component perpendicular to the axis of the line when the line is hanging taut under gravity.
