Abstract: The present invention relates to an assembly for rotating a suspended load around a substantially vertical axis, the assembly comprising an inner rim configured to have a fixed relationship with the suspended load to be rotated, an outer rim engaging the inner rim in a manner so that the inner and outer rims are configured to perform rotational movements relative to each other during rotation of the suspended load, and a drive unit for performing the relative rotational movement between the inner and outer rims. The assembly of the present invention may be secured to a lifting yoke for lifting wind turbine related components, such as entire wind turbine towers, wind turbine tower sections, nacelles, rotor blades or containers.

Abstract: A power pack is located within a housing on the platform of a wind turbine generator tower. The power pack is supplied from a fuel tank. With the door of the housing open, the power pack may be removed for servicing and repair by using a U-shaped support structure to which an electric motor is mounted. Two support rails permanently located within the housing support the housed power pack. A chain attached to the power pack is driven by the motor to remove the power pack from the housing by sliding the power pack along the support structure. A pulley arrangement reduces the necessary torque. After removing the power pack from the housing, a crane is used to lift the power pack from the platform and to lower it down to a sea vessel. The crane may also be used in the refilling of the fuel tank by hauling a fuel line from a sea vessel up to the platform and connecting it to the fuel tank.

Abstract: A method of controlling a floating-body wind turbine power generating apparatus including a wind turbine generator disposed on a floating body includes a pitch-angle increasing step of increasing a pitch angle of a blade of the wind turbine generator when the wind turbine generator is stopped, so that an aerodynamic braking force is applied to a rotor of the wind turbine generator. In the pitch-angle increasing step, a first change rate of the pitch angle of the blade in a first period during which the wind turbine generator is in an inclining motion toward an upwind side from a vertical direction due to sway of the floating body, is smaller than a second change rate of the pitch angle of the blade in a second period during which the wind turbine generator is in an inclining motion toward a downwind side from the vertical direction due to the sway of the floating body.

Abstract: The control system of this floating wind turbine generator is a control system of a floating wind turbine generator in which the control system controls a pitch angle control section by a pitch angle instruction value calculated on the basis of signals detected by a second sensor detecting a relative angle between a nacelle and a tower and a third sensor detecting a yaw angle from a reference position of the tower so that a signal detected by a first sensor detecting wind direction deviation relative to a vertical direction of a rotation plane of wind turbine blades indicates an angle within a predetermined range from the vertical direction of the rotation plane of the wind turbine blades, and controls a yaw driving device by a yaw driving instruction value calculated on the basis of the signals detected by the second sensor and the third sensor.

Abstract: A method of controlling a wind turbine includes: accumulating a cumulative damage degree Du of each evaluation point of the wind turbine in a unit period over an entire evaluation period, to calculate a total cumulative damage degree Dt of the entire evaluation period at each evaluation point; comparing the Dt at each of the evaluation points with a first threshold value (P*Q) and comparing an increase rate dDt/dt of Dt at each evaluation point with a second threshold value to evaluate fatigue of a part to which each evaluation point belongs; and determining an operation mode based on an evaluation result into a normal operation mode or a low-load operation mode in which an output is suppressed compared with the normal operation mode.

Abstract: The invention relates to a leading edge protection cover for a wind turbine blade. The protection cover comprises first and second longitudinally extending edges, and outer and inner arcuate surfaces extending there between. The inner arcuate surface is shaped to be attached to an outer surface portion of the wind turbine blade such as to cover at least a part of the leading edge of the blade, and with the first longitudinally extending edge being attached to a suction side of the wind turbine blade. The protection cover further comprises a number of vortex generating members positioned on the outer arcuate surface of the protection cover along at least a part of the first longitudinally extending edge. The proposed protection cover results in an increased protection of the wind turbine blade against impacting particles and improved fluid properties over the surface of the wind turbine blade. The invention further relates to a method of preparing a wind turbine blade with a leading edge protection cover, comprising the steps of moulding a leading edge protection cover comprising a number of vortex generating members and attaching the leading edge protection cover to an outer surface portion of the wind turbine blade.
