    Abstract: According to a first aspect of the invention, there is provided a wind turbine blade having a split blade configuration, comprising a first blade module defining an aerofoil profile and a second blade module defining an aerofoil profile; a damping module intermediate the first blade module and the second blade module; wherein the damping module comprises a first blade interface for joining to the first blade module and a second blade interface for joining to the second blade module. The damping module comprises a vibration damping unit. Beneficially, the invention provides a useful way in which to integrate motion damping functionality into a modular wind turbine blade.

    Abstract: A method for controlling tilt moment (10) of a wind turbine (1) is disclosed. One or more wind turbine blades (5) are connected to a blade carrying structure (4) via a hinge (6), each wind turbine blade (5) thereby being arranged to perform pivot movements relative to the blade carrying structure (4) between a minimum pivot angle and a maximum pivot angle. The wind turbine (1) further comprises an adjustable biasing mechanism (8, 11, 12) arranged to apply an adjustable biasing force to each wind turbine blade (5) which biases the wind turbine blade (5) towards a position defining minimum pivot angle or towards a position defining maximum pivot angle. Upon determining that tilt moment reduction is required, azimuth position of each of the wind turbine blades (5) is monitored, and the biasing force applied to each wind turbine blade (5) is changed as a function of azimuth position for wind turbine blades (5) in at least some azimuth positions above a horizontal level or for wind turbine blades (5) in at least some azimuth positions below the horizontal level.

    Abstract: A method of retrofitting a wind turbine (10) having a wind turbine tower (12) and a first energy generating unit (14) includes rotating at least a portion of the wind turbine tower (12). The wind turbine tower (12) is secured to a foundation (16) and has a first position on the foundation (16). The method includes rotating at least a portion of the wind turbine tower (12) from the first position to a second position. In the second position, the portion experiences less stress when the wind turbine (10) is operated in the same prevailing wind. The wind turbine tower (12) may have at least two sections (12a, 12b, 12c) and wherein rotating includes rotating one section relative to another section. One section may be secured to a foundation (16). In that case, rotating may or may not include rotating the section secured to the foundation (16). Rotating the tower may occur after the first energy generating unit (14) is removed from the tower and may include rotating the wind turbine tower by an angle from 90°±15° relative to the first position.

    Abstract: A multirotor wind turbine (1) comprising a vertical tower and at least two energy generating units (5), a load carrying structure (9, 10) extending transverse to the vertical direction and carrying the at least two energy generating units (5); and at least one escape route extending between a start and an exit. To provide a safe escape route, the load carrying structure forms at least a first section of the escape route from the start to an intermediate location, and the wind turbine comprises an escape opening in the nacelle, the escape opening leading from an interior space of a nacelle of the energy generating unit to a passage structure and the passage structure extending from the escape opening to the start of the escape route.
