Abstract: A wind turbine foundation structure comprising a hollow structural element with a circumferential wall extending in the longitudinal direction. A first cable feed-through breaking through the wall is arranged in the wall. A transition piece with an overlap region projects into the hollow structural element and a transition region projects out of the hollow structural element at the end face. A circumferential wall extends in the longitudinal direction. A second cable feed-through which breaks through the wall is arranged in the overlap region in the wall. The first and the second cable feed-through bear against one another in an at least partially overlapping manner in the assembled state of the hollow structural element and the transition piece.

Abstract: An offshore wind energy system comprising a foundation having a first hollow structural element with a longitudinally extending, circumferential first wall. A cable bushing penetrates through the first wall and is arranged in the first wall. At least one cable guide arrangement extends in a radial direction and is arranged at an outer shell surface of the first wall of the first hollow structural element. The cable guide arrangement is configured to guide a submarine cable exiting the cable bushing from the cable bushing to a submarine bottom surface.

Abstract: Supporting structure, in particular for a wind power plant, having at least two sub-segments which are at least partially connected to one another and are respectively formed from a metal plate having a longitudinal extent and a width extent. The longitudinal extent being greater than the width extent, and the sub-segments each having longitudinal edges extending in longitudinal extent and being connected to one another at mutually abutting joint surfaces along the longitudinal edges by a welded joint respectively. The sub-segments respectively have end edges extending in width, the sub-segments being bent along their end edges respectively. The respective welded joint has in sections a thickness which is smaller than a wall thickness of the metal plate and in sections a thickness which corresponds at least to the wall thickness of the metal plate.

Abstract: The invention relates to a support structure, in particular for a wind turbine, having at least two segments, which are joined to one another such that their longitudinal axes extend substantially collinearly to one another. At least one of the segments is a pipe section, which has at least two mutually facing abutment surfaces that are joined to one another, at least in parts. A support structure is provided that is producible in less time and is more cost-effective because the join between the abutment surfaces involves at least one welded join, the thickness of the welding join being less than the wall thickness of the pipe section, and/or the join between the abutment surfaces involves at least one retaining clip.
