Es ist bekannt, Windenergieanlagen mittels eines Fundamentes an Land in windreichen Gegenden zu befestigen. Derartige Windenergieanlagen haben jedoch den Nachteil, dass sie Platz an Land verbrauchen und in besiedelten Gebieten die Bevölkerung akustisch und ggf. auch optisch stören.It is known, wind turbines by means of a foundation on land to attach in windy areas. Such wind turbines have however the disadvantage that they consume place on land and in populated Areas the population acoustically and possibly also visually disturbing.
Aus diesem Grund wurde vorgeschlagen, Windenergieanlagen auf See, d.h. off-shore, zu befestigen. In küstennahen Gewässern wurde beispielsweise vorgeschlagen die Windenergieanlagen auf sog. Monopiles zu montieren. Diese Monopiles werden im Meeresgrund verankert und ragen aus dem Wasser heraus. Die Länge solcher Monopiles ist ca. 40 Meter. Mit ihnen können Windenergieanlagen bei Wassertiefen von bis zu 18 Meter befestigt werden. Nachteilhaft an einer solchen Befestigungsvorrichtung für eine Windenergieanlage ist jedoch, dass sie für größere Wassertiefen nicht geeignet ist. Außerdem ist diese Befestigungstechnik sehr aufwändig und teuer.Out For this reason, it has been suggested that wind turbines at sea, i. off-shore, attach. In the coastal area waters was proposed, for example, the wind turbines on so-called. To mount monopiles. These monopiles are anchored in the seabed and stick out of the water. The length of such monopiles is approx. 40 meters. With them you can Wind turbines attached at water depths of up to 18 meters become. A disadvantage of such a fastening device for a wind turbine However, that is for her greater water depths not suitable. Furthermore This fastening technique is very complicated and expensive.

Bei herkömmlichen Befestigungsvorrichtungen für Off-shore-Windenergieanlagen besteht das Problem, dass die Vorrichtung ein möglichst stabiles Fundament für die Windenergieanlage im Wasser bilden soll.at usual Fastening devices for Off-shore wind turbines have the problem that the device one possible stable foundation for The wind energy plant should form in the water.
Es ist die Aufgabe der vorliegenden Erfindung, eine Befestigungsvorrichtung für eine Off-shore-Windenergieanlage der Eingangs genannten Art bereitzustellen, mit der eine Windenergieanlage kostengünstig und stabil im Wasser befestigt werden kann.It The object of the present invention is a fastening device for an offshore wind turbine to provide the aforementioned type, with a wind turbine economical and can be stably fixed in the water.
Diese Aufgabe wird erfindungsgemäß durch eine Befestigungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen ergeben sich aus den Unteransprüchen.These The object is achieved by a Fastening device solved with the features of claim 1. advantageous Training and further developments emerge from the subclaims.
Das Fundament der erfindungsgemäßen Befestigungsvorrichtung ist ein länglicher Schwimmkörper, der vertikal ausgerichtet ist. Es hat sich herausgestellt, dass die vertikale Ausrichtung des Schwimmkörpers im Vergleich zu Katamaran-ähnlichen, horizontal ausgerichteten Schwimmkörpern den Vorteil bietet, dass sie eine höhere Stabilität bereitstellt und sicherer gegen Kentern ist. Außerdem ist eine solche Befestigungsvorrichtung kostengünstiger herstellbar, da nur ein Schwimmkörper benötigt wird, wohingegen bei Katamaran-ähnlichen Befestigungsvorrichtungen zumindest zwei Schwimmkörper benötigt werden. Des Weiteren sind die Schwankungen auf Grund der Windkräfte und der Wellenbewegungen geringer als bei Katamaran-ähnlichen Befestigungsvorrichtungen.The Foundation of the fastening device according to the invention is a longish one Float, which is vertically aligned. It turned out that the vertical orientation of the float compared to catamaran-like, horizontally oriented floats offers the advantage that a higher one stability provides and is safer against capsizing. In addition, such a fastening device cost-effective Can be produced as only one float is needed whereas catamaran-like Fastening devices at least two floats are needed. Furthermore, the fluctuations due to wind forces and the wave movements less than in catamaran-like fastening devices.
Die Ankermittel umfassen vorzugsweise mehrere Seile oder Ketten, die an jeweils einem Ende mit dem schwimmenden Fundament verbunden sind und an dem jeweils anderen Ende Mittel zum Befestigen der Seile oder Ketten im und/oder am Meeresgrund aufweisen. Es sind zumindest zwei Seile oder Ketten oberhalb des Schwerpunkts des Fundaments an diesem befestigt und zumindest zwei Seile oder Ketten unterhalb des Schwerpunkts an dem Fundament befestigt. Gleichermaßen können auch drei Seile oder Ketten oberhalb und drei Seile oder Ketten unterhalb des Schwerpunkts des Fundaments an diesem befestigt sein. Hierdurch kann eine besonders stabile Lage des schwimmenden Fundaments erzeugt werden.The Anchoring means preferably comprise a plurality of ropes or chains which connected at one end to the floating foundation and at the other end means for attaching the ropes or chains in and / or on the seabed. It is at least two ropes or chains above the center of gravity of the foundation attached to this and at least two ropes or chains below of the center of gravity attached to the foundation. Likewise, too three ropes or chains above and three ropes or chains below the center of gravity of the foundation to be attached to this. hereby can create a particularly stable position of the floating foundation become.
Gemäß einer vorteilhaften Ausgestaltung der erfindungsgemäßen Befestigungsvorrichtung ist die Masseverteilung des Fundaments derart, dass es sich im Wasser selbsttätig vertikal ausrichtet. Die Ankermittel sind somit nur noch für die Positionierung der Befestigungsvorrich tung und nicht für die Ausrichtung des Fundaments erforderlich. Das Fundament weist z.B. an dem zu den Haltemitteln für die Windenergieanlage entgegengesetzten Ende eine größere Dichte auf. Die Dichteverteilung des Fundaments kann insbesondere dadurch verändert werden, dass Teile des Fundaments mit Wasser geflutet werden. Auf diese Weise kann die Befestigungsvorrichtung sehr flexibel an verschiedene Größen und Gewichtsverhältnisse angepasst werden.According to one advantageous embodiment of the fastening device according to the invention the mass distribution of the foundation is such that it is in the water automatic aligns vertically. The anchor means are thus only for the positioning of the Fastening device and not for the alignment of the foundation required. The foundation has e.g. on the to the holding means for the wind energy plant opposite end a greater density on. The density distribution of the foundation can be characterized in particular changed be that parts of the foundation be flooded with water. On In this way, the fastening device can be very flexible to different Sizes and weight ratios be adjusted.
Gemäß einer bevorzugten Weiterbildung der erfindungsgemäßen Befestigungsvorrichtung stellen die Ankermittel eine dynamische Verankerung bereit, bei der eine begrenzte horizontale und/oder vertikale Bewegung des schwimmenden Fundaments relativ zu den Befestigungspunkten im und/oder am Meeresgrund möglich ist. Durch eine solche dynamische Verankerung kann eine sichere Befestigung des Fundaments auch dann gewährleistet werden, wenn sehr große Kräfte auf die Befestigungsvorrichtung einwirken.According to a preferred embodiment of the fastening device according to the invention, the anchoring means provide a dynamic anchoring in which a limited horizontal and / or vertical movement of the floating foundation relative to the attachment points in and / or on the sea Resound is possible. By such dynamic anchoring a secure attachment of the foundation can be ensured even when very large forces acting on the fastening device.
Gemäß einer bevorzugten Weiterbildung der erfindungsgemäßen Befestigungsvorrichtung sind an dem Fundament zusätzlich schwimmende Ausleger zum vertikalen Stabilisieren der Befestigungsvorrichtung befestigt.According to one preferred development of the fastening device according to the invention are additional to the foundation Floating boom for vertical stabilization of the fastening device attached.
Gemäß einer weiteren bevorzugten Ausbildung der erfindungsgemäßen Befestigungsvorrichtung weist das Fundament einen vertikal ausgerichteten zylindrischen Abschnitt auf, entlang dem ein spiralförmiger Flügel zum vertikalen Stabilisieren der Befestigungsvorrichtung entlang läuft. Mittels eines solchen spiralförmigen Stabilisators kann die Befestigungsvorrichtung besonders wirksam in der Vertikalen gehalten werden.According to one Another preferred embodiment of the fastening device according to the invention the foundation has a vertically oriented cylindrical Section on, along which a spiral wing for vertical stabilization the fastening device runs along.
