A system includes a float including a drivetrain, a reaction structure coupled to the drivetrain by a tendon, and an extension spring having a first end coupled to a fixed point on the tendon and a second end configured to be disposed at a fixed location relative to the drivetrain. The extension spring is configured to experience an elastic force in response to tension on the first end of the extension spring away from the drivetrain.

A transitioning wind turbine for land or offshore use having a tower base; a wind turbine tower attached to the tower base; a wind turbine attached to the wind turbine tower having a hub and an outer perimeter with spokes disposed between the hub and outer perimeter; a set of vanes carried by the spokes; a generator configured to engage the outer perimeter of the wind turbine and convert a rotational energy of the outer perimeter into power; a lifting tower having a pivot disposed at a proximal end of the lifting tower; a cable attached between the lifting tower and the wind turbine tower; and, wherein the lifting tower is configured to transition from the upright position to the tilted position as the wind turbine tower transitions between the horizontal position to the vertical position.

Provided is an arrangement for transporting a wind turbine component, the arrangement including: a first portion adapted to be placed on a loading area, in particular of a trailer; a second portion, in particular component adapter portion, adapted to support the component; the first portion and the second portion each having a respective connection interface via which the first portion and the second portion are reversibly couplable to each other.

A wind turbine (10) includes a tower (12), a nacelle (14) coupled to the tower (12) and housing one or more heat generating components (18, 20), a rotor (16) having a least one wind turbine blade (24), and a cooler (38) mounted to the nacelle (14) and configured to cool the one or more heat generating components (18, 20) in the nacelle (14) by circulating a working fluid. The cooler (38) includes a support frame (46) coupled to the nacelle (14) and a heat exchanger (48) coupled to the support frame (46) and configured to cool the working fluid. The heat exchanger (48) includes at least two cooling panels (58) in non-planar relation with each other. The at least two cooling panels (50) may also be pivotably coupled to each other. A method of assembling a cooler (38) is also disclosed.

A runner for a hydraulic machine comprising a band, a crown, a plurality of blades extending between the crown and the band, wherein the runner comprises a plurality of runner segments which together define the runner, each runner segment comprising a band portion, a crown portion and a blade, which portions are integrally formed with one another, each runner segment being attachable to another segment at a band joining edge and a crown joining edge, wherein the band joining edge and the crown joining edge are each spaced apart from the blade of the segment.

The invention relates to an assembly method for a vibration damper of a tower of a wind power plant, in which the vibration damper is switched into a transport state from a state of use. The vibration damper is connected to a structural component of the tower such that a damper mass of the vibration damper can be set in motion, during which movement the distance between the damper mass and a central axis of the tower varies. The vibration damper is switched into the transport state by tilting the vibration damper compared to the state of use. The invention also relates to an associated assembly system.

The invention relates to a floating windmill installation (1, 1′, 1″), wherein the floating windmill installation (1, 1′, 1″) comprises: —a windmill (10, 10′) comprising a tower (14), —a floating installation (20, 20′) comprising an aperture (22) penetrating the floating installation (1, 1′, 1″) for accommodating the tower (14), and—means for raising and lowering the tower (14) up and down through the aperture (22).

The disclosed subject matter provides a system and method for facilitating bonding of various turbine blade components, including trailing edge inserts, or flatbacks, to the trailing edge of a wind turbine blade. The system disclosed herein ensures a consistent force is applied from root to top thereby preventing defects, e.g. paste voids, from forming. Additionally, a consistent bonding gap can be achieved due to the consistent application of force from the root to tip of the blade.

A fixture system for rail transport of wind turbine blades upon a consist of flatcars using a root-support fixture, a blade-support fixture, and first and second guide post that intermittently engage the tip-end portion of the wind turbine blade to limit lateral movement thereof, such that movement of the consist around a curved railway section urges the wind turbine blade against the first or second guide posts, which urges the wind turbine blade to urge the blade-support fixture to move laterally, thereby laterally reorienting the blade upon the consist.
