In the assembly of the support structure of a wind turbine, N sets of a first tubular brace and a second tubular brace extend from a tower support. For each set, the second braces are connected at one or both of their end parts by a casted connection. The first brace or the tower structure has a casting cavity for accommodating an end of the corresponding second brace. In order to assemble the construction, the second brace is inserted into the cavity, after which the end of the first brace is lifted until the end of the second brace is inserted deeply enough into the respective cavity.

A method for assembling a floating offshore wind farm, including: arranging at least N floating structures on a body of water; providing mast sections for assembling at least N masts; providing turbines and blades for at least N wind turbines; selecting at least one floating structure referred to as the mounting floating structure, the other floating structures being receiving floating structures; fastening a lifting device to the mounting floating structure; moving the mounting floating structure up to a receiving floating structure, and using the lifting device to lift and mount at least one constituent element of a wind turbine on the receiving floating structure; repeating the preceding step for the other receiving floating structures.

Described is a device for offshore arranging of a wind turbine or components thereof on a foundation present at sea. The device includes an elongate superstructure connected releasably to the foundation and extending between a lower surface and an upper surface thereof in the vertical direction from the foundation. The superstructure has an internal space which is accessible to a tower section of the wind turbine and in which the tower section can be received. Further present is a horizontally displaceable supply structure for a tower section. The supply structure is configured to move a tower section coupled thereto from outside the internal space into the internal space by a horizontal displacement. An engaging structure, received for vertical displacement in the internal space, is configured to lift an engaged tower section in the internal space by a vertical displacement, whereby sufficient space is created under the relevant tower section for receiving another, underlying tower section in the internal space.

The present invention can be included in the technical field of concrete segments for wind turbine towers and more specifically for wind turbine towers in cold climates, where ambient temperature is below 5 C. at the same time, the invention relates to a set of a concrete segment and heating means, a concrete section, a wind turbine, a mould and a method of assembling the wind turbine.

A system and method are provided for manufacturing a tower structure. Accordingly, a first printed layer of a wall element is deposited with a printhead assembly, and an actual midline perimeter length of the first printed layer is determined. A horizontal reinforcement assembly is then formed based, at least in part, on the actual midline perimeter length. The formed horizontal reinforcement assembly is positioned in a horizontal orientation on the first printed layer and in axial alignment with the vertical axis of the tower structure. With the horizontal reinforcement assembly positioned on the first printed layer, a second printed layer of the wall element is deposited via the printhead assembly on the horizontal reinforcement layer.

The present invention relates to an elongate member and methods of its formation and assembly, the elongate member constructed of a stacked sequence of adjacent sections, the elongate member comprising, at each interface of adjacent sections, a lower seat member of an upper more of said adjacent sections, and an upper seat member of a lower more of said adjacent sections, wherein said upper and lower seat members at each interface having been match-cast as a seat member pair and seated with each other in the same relative position as the relative position the seat member pair was match-cast in.

A system for the automated lifting of a wind turbine mounted on a transition piece with a tubular tower, nacelle and corresponding blades thereof. A lifting triangle that passes, through a retractable bolt, through the bottom ends of columns of the transition piece, the joining thereof being completed with the hydraulic presses, ascends and descends in direct contact with the three masts. The masts are mounted on bases disposed on the ground and anchored to foundations. Cables extend from a winch, pass through pulleys at the top of the mast and connect to a fixed pulley block and to a moveable pulley block of the triangle.

A portable power generation system having a transportable structure can include a wind turbine having a tower mounted to the transportable structure configured to allow erection from within the transportable structure. It can also include a solar panel array pivotally connected to the structure that is expandable to an in use configuration in which the expanded solar panel is inclined to a side of the transportable structure.

A method for the arrangement of at least one component during the installation of a wind turbine is provided, wherein the component is releasably attached to a tower segment prior to a coupling of the tower segment to a tower segment support structure, wherein the tower segment forms at least a section of a tower of the wind turbine to be installed and wherein the component is attached to an attachment area at the outer surface of the tower segment, wherein the component is moved from the attachment area to an arrangement position after coupling of the tower segment to the tower segment support structure.
