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 method of preventing nacelle drop in a multiple rotor (MR) wind turbine during mounting of a nacelle to the MR wind turbine, the MR wind turbine comprising a tower (2) extending in an upwards direction, a load carrying structure (3, 4) forming a first section (3) and a second section (4), the first and second sections extending in different directions away from the tower (2). To reduce the impact of a nacelle drop and therefore an abrupt change in the loading of the load carrying structure, the method comprises attaching at least one tension wire (20, 30, 60, 61) to one of the first section (3) and second section (4) such that vertical movement of an interface portion of the first section is reduced by the at least one tension wire, mounting the nacelle (5) to the first section (3), and subsequently removing the at least one tension wire (20, 30, 60, 61).

Abstract: The invention provides a wind turbine comprising a load carrying structure and an energy generating unit. The load carrying structure is connected to the energy generating unit and holds the energy generating unit above ground. The energy generating unit houses a facility which requires a particular orientation relative to gravity for being operational. Furthermore, the energy generating unit comprises an adaptation structure e.g. arranged between the load carrying structure and the facility. The adaptation structure facilitates a first configuration with a first position of the facility relative to the load carrying structure, and a second configuration with a second position of the facility relative to the load carrying structure.

Abstract: A method for mounting or dismounting a wind turbine component of an energy generating unit in a multirotor wind turbine is disclosed. The multirotor wind turbine comprises a tower configured to support one or more load carrying structures each arranged for supporting at least two energy generating units arranged at or near its ends and at opposite sides of the tower. The method comprises securing the load carrying structure against up and down tilting movements before positioning or dispositioning the wind turbine component at an end of the load carrying structure thereby reducing the loadings arising from the unbalance caused by the positioning or dispositioning the wind turbine component. The securing may be realized by compression bars, tethering, or the use of a counterweight.
