Support structure floating in the open sea and connected to anchors by bracing means, for wind turbines, service stations, or converter stations

Abstract

The invention relates to support structures that float in the open sea and are connected to anchors by bracing means, for wind turbines, service stations, or converter stations. Said structures are in particular characterized by secure and stable anchoring. To this end, the support structure has a first component, which is arranged under water, and a second component, which cuts through the water surface. Furthermore, the first component has first buoyant bodies, which are arranged at the corners of a polygon and act as supports of the second component, and tubular second buoyant bodies, which connect said first buoyant bodies to each other. A node structure, which connects at least two second buoyant bodies to each other, and at least one U-shaped node plate are arranged in the first buoyant body. The node structure is at the same time the support for a tubular support element and thus in conjunction with the node plate is a node, which absorbs and dissipates forces, of the underwater structure. The second component has tubular support elements, which cut through the water surface and are connected via support means to a support construction for the wind turbine, service station or converter station.

Description

technical field [0001] The invention relates to a load-bearing structure for a wind power installation, a service station or a converter station, floating in the open sea and connected to an anchor via a tensioning mechanism. Background technique [0002] For example, document GB 2378679A discloses a floating floating body connected to an anchor for a wind power installation in the open sea. The floating foundation realized for this consists of a plurality of floating bodies connected via radial steel girders to the tower of the wind power installation. The steel girders are arranged in a cross shape when viewed from above and are not connected to one another. If bending forces occur on the radial steel beams of a building structure, this will result in high bending moments. [0003] A quadrangular floating base is known from document WO 2007 / 096680 A1, wherein the floating bodies arranged at the corners are connected to each other by tension rods and pressure rods to form...
