Abstract: A logistics system for a multirotor wind turbine (1) is disclosed. The multirotor wind turbine (1) comprises two or more energy generating units (4), each mounted on an arm (3) extending from a tower (2) of the multirotor wind turbine (1). A transport system (14, 30, 31, 32, 33, 34, 36) interconnects a lower interior part of the tower (2) with each of the energy generating units (4). A plurality of transport containers (15) is connectable to the transport system (14, 30, 31, 32, 33, 34, 36) and configured to hold equipment (26) to be transported. A control unit is configured to receive information regarding contents and position of the transport containers (15), and to plan transport of the transport containers (15) via the transport system (14, 30, 31, 32, 33, 34, 36), based on a service plan for the multirotor wind turbine (1).

Abstract: A method and a device for dampening movement in a multiple rotor (MR) wind turbine located at sea and 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 provide efficient dampening of the movement, the method comprises tethering a first body (20) to the first section (3), the first body being at least partly submerged into the sea.

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.

Abstract: A multirotor wind turbine (1) comprising a tower (2), a yaw arrangement (6) and at least two energy generating units (4) is disclosed. The yaw arrangement (6) is carried by the tower (2) and comprises an outer wall (7) being rotationally suspended about the tower (2). Each energy generating unit (4) is carried by an arm (3) extending from the outer wall (7). The multirotor wind turbine (1) further comprises a load management system (14, 30, 31, 32, 33, 34, 36) for hoisting articles (15, 26) from the tower bottom to each energy generating unit (4) via the yaw arrangement (6).
