A foundation device for a wind turbine tower includes a hollow main body with a lower face and an upper face. Both the lower face and the upper face contain a hollow space. Each of the faces include an outer perimeter and an inner perimeter. The main body additionally includes an outer lateral wall disposed between the outer perimeter of the lower face and the outer perimeter of the upper face, and an inner lateral wall between the inner perimeter of the lower face and the inner perimeter of the upper face. The device further includes a plurality of columns that project from the upper face of the main body.

Systems and method for a hydrokinetic energy device. A hydrokinetic energy device includes a main body including two main wing-shaped spars mounted upon a rotating central hub, and rotatable spar tip turbines mounted at or near an end of each of the main wing-shaped spars, the main wing-shaped spars driving the rotatable spar tip turbines through water, each of the rotatable spar tip turbines including a direct-drive generator and power conversion system that transfers power from a rotating rotatable spar tip turbine to the central hub where the voltage is stepped up and amperage is reduced.

Systems, methods, and vehicles for loading and unloading cargo from a long-distance transport vehicle, such as an aircraft, are described. The systems and methods include operating a plurality of vehicles to unload large cargo from the aircraft and transporting the large cargo to an installation site. In some instances, the vehicles hold the payload the entire time, including while loading aircraft, during flight, unloading the aircraft, and moving the payload to the installation site. Alternatively, the vehicles can drive on the plane to load the payload to a designated area, and equivalent vehicles can drive on the plane after the payload has been flown to unload the payload and moving the payload to the installation site. Various vehicles and systems, and components thereof, along with methods of operating the same, are also provided.

A temporary damper assembly for use during vertical storage and/or vertical transport of a tower: includes a liquid damper tuned to the natural frequency of vibration of the tower; a tower cover realized to cover an annular upper opening of the tower during storage and/or transport; a mounting interface configured to suspend the liquid damper from the annular upper opening of the tower; and a load transfer interface for the transfer of loads between the liquid damper and the tower. A method of suppressing vortex-induced vibration in a tower during vertical storage and/or vertical transport of the tower is also provided.

Provided is a helical strake set to reduce vortex induced vibrations of a tower, intended to be transported unassembled in a container, including a plurality of identical attachable segments, wherein each segment includes a main body of hollow pyramidal configuration including a wide polygonal end a narrow polygonal end and a narrow polygonal portion firmly attached to the narrow polygonal end, and each segment further including a cap including a wide polygonal portion able to fit in the wide polygonal end by a fastening element, wherein all main bodies and caps are able to be piled in one into another in a container yielding a significant reduction in seaborn transport volume and later assembled on site to reduce vortex induced vibrations of a tower.

An apparatus for transport of an object in a wind turbine is provided, the apparatus including a main frame, a number of support elements, and a number of transfer bearings attached to the main frame. The support elements are configured to receive the object and to secure the object at the main frame, and the transfer bearings each comprise a movable part that is movable around at least two axes relative to the main frame. Further, a transport system and a method for transport of an object in a wind turbine is also provided.

A wind turbine blade rotating and braking apparatus comprising: a root device including: a root support member having an upper surface with a radius of curvature and configured to receive a portion (e.g. root) of a wind turbine blade, rollers having a longitudinal axis parallel to the longitudinal axis of the blade and configured to rotate the blade; braking mount on the sides of the root support member; and a braking mechanism (e.g. strap or band) fixedly attached to the first mount, releasably attached to the second mount and extending above the blade to apply a braking force to the blade. Once applied, the braking force can be maintained by a locking pin.

A mobile lifting apparatus is provided for lifting an, in particular flat, transport frame on which a component of a wind turbine is mounted, in particular for removing or placing at least one self-propelled modular transporter below the transport frame, the lifting apparatus including: an upper part having an interface for connecting to a transport frame to be lifted, a lower part for supporting the lifting apparatus on the ground, and a lifting mechanism connecting the lower part to the upper part for linearly vertically moving the upper.
