Abstract

The invention relates to offshore wind turbines for converting wind energy into electrical energy, having a buoyant device, arranged under water, connected to a tower of the wind turbine, wherein the device has connecting means, buoyancy bodies and vertically arranged pipes or pipe sections, and the device is connected to at least one anchor via guy means. The offshore wind turbines are characterized in particular in that forces that arise as a result of movement of the offshore wind turbine can be dissipated into the anchoring via tensioning means. For this purpose, end regions of vertically arranged pipes or pipe sections of the device and/or of the anchor which face in the direction of the anchor and/or device have clamping mechanisms for fastening end regions of the guy means. The clamping mechanisms are further connected to the end regions of the vertically arranged pipes or pipe sections via universal joints as Cardan suspensions. The universal joints are advantageously joints that absorb and dissipate forces during movement of the offshore wind turbine. Bending forces arising in the guy means are largely avoided.

Abstract

The invention relates to a floatable offshore system for converting wind energy and/or solar energy into electric energy, comprising a support device which is coupled to at least one anchor via bracing means on one side and the other side of which is connected to a support frame, said support frame being connected to a tower of a wind turbine, or a support comprising a solar system, or a solar system and at least one wind turbine. The system is characterized in particular by its simple and economically advantageous implementation. For this purpose, first tubes which are connected to a first node piece are arranged in a horizontally star-shaped manner. The ends of two vertically arranged tubes are connected to the ends of the first tubes via connectors, and the second tube ends opposite the ocean floor are the support elements of either the support frame, which has third tubes and comprises a second node piece, or of the support. The buoyancy body is located on the second tubes.

Abstract

The invention relates to buoyant heavy weight anchors for anchoring a supporting structure floating in the open sea bearing a wind turbine, service station, or converter station. Said heavy weight anchors are in particular characterized in that the supporting structure bearing the wind turbine, the service station, or the converter station can be anchored on site in a simple way. To this end, the heavy weight anchor has a solid plate, a plurality of floodable chambers, and fastening means for buoyancy bodies of the supporting structure, wherein the buoyant heavy weight anchor has non-flooded chambers, the lowering heavy weight anchor has partially flooded chambers, and the lowered heavy weight anchor has flooded chambers. The buoyant heavy weight anchor is configured as a monolithic heavy weight anchor. The buoyant heavy weight anchor is thus floatable on site, and lowers itself by flooding the chambers. In the event of possibly existing currents, said heavy weight anchor only needs to be kept in position. Advantageously, the lowering can thereby be done in a specifically controlled manner by virtue of the flooding. As a matter of course, the flooded chambers increase the weight of the anchor on the bottom of the sea. The heavyweight anchor is designed monolithically.

Abstract

A support structure floating in the open sea and connected to anchors by bracing elements. The support structure has a first component arranged under water and a second component cutting through the surface of the water. Furthermore, the first component has first buoyant bodies arranged at corner points of a polygon and serving as carriers of the second component and second buoyant bodies connecting them with one another and having a tube shape. A nodal structure connecting at least two second buoyant bodies with one another and at least one U-shaped junction plate are arranged in the first buoyant body. The nodal structure is simultaneously the carrier for a tube-shaped support element and is therefore a node of the underwater support structure that absorbs and channels off forces in connection with the junction plate. The second component has the tube-shaped support elements cutting through the surface of the water.

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.

Abstract

The invention relates to load-bearing structures that float in the open sea and are connected to anchors via tension means, for wind power plants, service stations or converter stations. The load-bearing structures are distinguished in particular by the secure and stable anchoring thereof. To this end, the load-bearing structure has an underwater load-bearing structure and a load-bearing frame for the wind power plant or the constructions for the service stations or converter stations. The underwater load-bearing structure has - as core load-bearing structure, first buoyancy bodies that are arranged at the corners of a polygon, are connected together via in each case at least one first spacer body and act as supports for a load-bearing frame, and - second buoyancy bodies that are arranged as outriggers of the first buoyancy bodies, wherein each of the second buoyancy bodies is connected to the two adjacent first buoyancy bodies via at least one second spacer body. The first buoyancy bodies are arranged at the corners of a polygon and connected together via in each case at least one first spacer body. The load-bearing structure thus represents a spatial load-bearing structure in the form of a three-dimensional load-bearing structure.
