Abstract: A method for controlling a multirotor wind turbine (1) is disclosed. A first operational state of each of the energy generating units (5) of the wind turbine (1) is obtained. A difference in thrust acting on at least two of the energy generating units (5) is detected. At least one constraint parameter of the set of operational constraints is adjusted in accordance with prevailing operating conditions and in accordance with the detected difference in thrust, and a new operational state for at least one of the energy generating units (5) is derived, based on the at least one adjusted constraint parameter, the new operational state(s) counteracting the detected difference in thrust. Finally, the wind turbine (1) is controlled in accordance with the new operational states for the energy generating units (5).

Abstract: A support structure, such as a monopile, for a wind turbine, comprising a tubular body having a wall extending about a body axis, the wall defining a leading edge and an outer circumferential surface extending away from the leading edge and a plurality of fins supported on the wall near to the leading edge of the tubular body and extending in an axial direction. Each fin comprises a first fin portion that extends from the wall in a radial outwards direction with respect to the body axis and a second fin portion that extends from the wall in a radial inwards direction with respect to the body axis. Beneficially the arrangement of fins on the head of the support structure provides structural reinforcement to the pile wall so the pile is less likely to buckle during installation. Having fin portions that extend radially inwards and outwards from the pile wall means that the pile wall is supported evenly. The fins may also be provided with a fluid delivery system which is configured to inject fluid at pressure to tip regions of the fins. Such a configuration helps the monopile to penetrate the soil into which is being driven and therefore can reduce the required pile driving force.

Abstract: A first aspect of the invention provides a method of testing a yaw system (200) of a wind turbine, the wind turbine comprising a rotor; the yaw system (200) comprising a yaw gear (202) coupled to the rotor so that rotation of the yaw gear (202) causes yaw rotation of the rotor, and first and second sub-systems (204a, 204b), the first sub-system (204a) comprising a first pinion gear (206a) and a first drive motor (208a) coupled to the yaw gear (202) by the first pinion gear (206a), the second sub-system (204b) comprising a second pinion gear (206b) and a second drive motor (208b) coupled to the yaw gear (202) by the second pinion gear (206b). The method comprises the steps of: testing the first sub-system (204a) by: applying a first yaw moment to the yaw gear (202) with the second drive motor (208b) via the second pinion gear (206b), reacting the first yaw moment with the first pinion gear (206a), monitoring a yaw motion parameter indicative of rotation of the yaw gear (202), and determining a condition of the first sub-system (204a) based on the monitored yaw motion parameter.
