Abstract: This invention relates to a method for forming a mono pile foundation in soil for a wind turbine tower including drilling a plurality of holes into the soil, the plurality of holes being arranged along a curve having a contour corresponding to a cross-dimensional shape of the mono pile, and placing the mono pile in an annular cavity, the annular cavity being formed by the plurality of holes alone and/or by the mono pile breaking up intermediate soil walls between adjacent holes in the plurality of holes while being placed therein. A foundation in soil for a wind turbine tower, a wind turbine comprising such a foundation, and use of such a foundation in a wind turbine is also disclosed.

Abstract: An off-shore wind turbine includes a tower, a pile forming at least part of a foundation carrying the tower, a radial distance element extending outward from the tower and the pile, and a plurality of connecting elements extending from the radial distance element to at least one of the tower and pile, the plurality of connecting elements being configured to vertically align the tower on the pile. A method of erecting the wind turbine tower is also disclosed.

Abstract: A wind power plant includes a tower, the tower including at least one tower section provided with at least one flange and forming at least part of the wall of the tower. The power plant further includes an element provided with at least one flange and adapted to be installed adjacent the tower section. The tower section and the element have abutting flanges, the flanges being releasably interconnected by sets of bolts and nuts. At least one surface associated with each set of bolt and nut and facing away from the flanges is provided with a plurality of recesses for receiving projections of a tightening device. A method of joining a tower section and an adjacent element is also disclosed.

Abstract: This invention relates to a tower for a wind turbine, comprising one or more tubular tower sections, having an outer jacket wall and an inward directed flange in its lower and upper ends, and at least one platform arranged inside the tower for facilitating access for maintenance and repairs to the inner of the tower and to the nacelle. The tower also comprises a support structure including at least three elongated tensile load carrying members, which each is attached in its upper end to the upper flange of the tower section and in its lower end to the lower flange of the tower section and which supports one or more platforms that are suspended by the tensile load carrying members while at least one ladder is attached to the platforms. The at least one ladder is stabilized in the horizontal direction by transversal tensile load carrying members extending from the ladder to the tensile load carrying members that are vertically arranged between the upper and lower flanges.

Abstract: The invention relates to a wind turbine tower comprising a tower foundation, and at least two tower sections connected by numerous sets of connecting means positioned in close proximity of each other. The connecting means comprising at least one nut with at least one assembly opening for interacting with an assembly tool. The invention also relates to a method for assembling a wind turbine tower and a method for manufacturing a nut of connection means for fixating a wind turbine tower including at least two tower sections.

Abstract: The invention relates to a tower part (6) for a wind turbine (1) comprising at least one wall segment (9) and at least one aperture segment (10) including at least one aperture (7). The wall segment (9) and the aperture segment (10) being connected by connecting means and the aperture segment (10) is of a substantially uniform thickness and is thicker than the thickness of the wall segment (9). The invention further relates to an aperture cover system for covering at least one aperture (7) in a tower part (6) for a wind turbine (1). The system comprising cover plates and attachment means for attaching the system to the tower part (6), wherein the attachment means do not affect the fatigue limit of the tower part (6). Finally the invention relates to a method for manufacturing a wind turbine tower part (6) and uses hereof.

Abstract: The invention relates to a wind turbine including a foundation and a tower positioned on the foundation where the tower includes more than one modules, where the modules each include a separate strengthening structure defining the outer edges of the module and wind turbine equipment, and where the more than one module are positioned substantially vertically on top of each other in an upright position within the tower. The modules are connected directly and/or indirectly through the strengthening structure, to the foundation (18). The invention further relates to a method for assembling a wind turbine at a wind turbine site and a method for handling more than one wind turbine modules.
