Abstract: A method for controlling a multirotor wind turbine (1) comprising two or more energy generating units (5) is disclosed. At least one load carrying structure (3) is connected to a foundation or to a tower (2) via a yaw arrangement (4), and the load carrying structure (3) carries the at least two energy generating units (5). A requirement to a change in operation of at least a first of the energy generating units (5) is detected. Control commands for the first energy generating unit (5) and for at least a second energy generating unit (5), mounted on the same load carrying structure (3), are generated. The control commands cause the required change in operation, and the control commands cause coordinated operation of at least the first energy generating unit (5) and the second energy generating unit (5). The control commands are generated under the constraint that a yaw moment (9) of the yaw arrangement (4) is maintained below a predefined threshold level.

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 multirotor (MR) wind turbine (1) comprising a plurality of energy generating units (5) attached to a load carrying structure (3) carried by a tower via a main yaw assembly. The energy generating units (5) are attached to the load carrying structure via a local yaw assembly which allows yawing of the energy generating unit relative to the load carrying structure. To allow individual orientation of each energy generating unit, the MR wind turbine is configured to define an operational angle of each energy generating unit relative to an prevailing wind direction. This operational angle corresponds to a normal operational situation where the energy generating unit converts wind energy. The MR wind turbine is further configured to yaw each energy generating units to and from the operational angle individually by use of the local yaw assembly.

Abstract: A multirotor (MR) wind turbine (1) comprising a plurality of units (5) attached to a load carrying structure (3) carried by a tower via a main yaw assembly. The units (5) are attached to the load carrying structure via a local yaw assembly which allows yawing of the unit relative to the load carrying structure. To allow easy access into the units, each unit has a defined parked position where an entrance structure into an internal space of the unit is accessible from the load carrying structure.

Abstract: The present invention relates to a multirotor wind turbine comprising at least two rotor nacelle assemblies mounted to a support arrangement via respective yawing systems, and a toe angle control system for controlling the toe angles of the rotor nacelle assemblies with respect to the 5 support arrangement; wherein the toe angle control system is configured to operate in a first mode in which the rotor nacelle assemblies are held at positive toe angles while the wind turbine is generating power in a main production mode; wherein the toe angle control system is further configured to monitor the operating mode of the wind turbine, and to switch to a second mode in which the yawing systems of the rotor nacelle assemblies are operated to 10 reduce the toe angles of the rotor nacelle assemblies if an operating mode-based trigger condition has been met.

Abstract: Aspects of the present invention relate to a nacelle (14) for a wind turbine generator (10), and a method for transferring components into and out of a wind turbine generator (10). The nacelle (14) comprises a housing (26) surrounding an internal volume (24) of the nacelle (14). The housing (26) has a maintenance opening (50). The nacelle comprises a carriage (54) configured to hold a component (48), the carriage (54) being movable between a first position and a second position to transfer the component (48) through the maintenance opening (50). When the carriage (54) is in the first position, the component (48) is held within the internal volume (24). When the carriage (54) is in the second position, the component (48) is held such that at least a portion of the component (48) is outside the housing (26).
