Problems solved by technology

This makes it difficult to transport tower sections, especially tubular base sections for wind turbine towers, due to increased wall thickness or due to exceeding physical constraints imposed by infrastructure (e.g., under bridges or tunnels) the gap in the diameter) tends to become too heavy

Embodiment Construction

[0037] figure 1 An offshore wind turbine site 100 including a plurality of wind turbines 102 is schematically depicted. Each wind turbine 102 includes a rotor 104 configured with a set of blades 106 . The rotor is placed on top of a wind turbine tower 107 on a foundation (not shown) fastened to the seabed. The foundation is provided, for example, in the form of another tower structure (so-called "monopiles"). The blades 106 rotate the rotor 104 as the wind blows. The rotor 104 drives a generator (disposed in the housing 108), thereby generating energy. figure 2 A mobile floating wind turbine tower structure production facility 200 is schematically depicted, here a barge having an open storage deck 201 and a production deck 202 with the fabrication facility located below the open storage deck 201 .

[0038] Here, the fabrication facility includes a rolling mill 204, a welding station 206 for forming tubular subsections, a welding station 208 for joining a plurality of tubu...

Abstract

A method of manufacturing a tubular wind turbine tower structure, comprising the steps of: providing a plurality of tubular tower structure sub-sections at a movable wind turbine tower structure production facility; and welding the plurality of tubular sub-sections together to form the tubular wind turbine tower structure. Hereby, a rational production of the wind turbine tower structures can be achieved while at the same time facilitating road transport of material for the towers.

Description

technical field [0001] The present invention relates to a method of manufacturing a tower structure for a wind turbine and a wind turbine tower structure production facility. Background technique [0002] Conventionally, when constructing a wind turbine, steel tower sections are fabricated at a factory, and each completed tower section is transported to the site where the wind turbine is to be assembled. Thus, multiple tower structures can be assembled on top of each other to form a wind turbine tower. [0003] The increased demand for higher capacity wind turbines for land-based as well as offshore assembly sites has resulted in a need for wind turbine towers with higher structural strength than currently used towers. [0004] For tubular wind turbine towers, this higher structural strength can be achieved by increasing the wall thickness and / or diameter of the tower. This makes it difficult to transport tower sections, especially tubular base sections for wind turbine to...
