Description
Die Erfindung betrifft eine Offshore-Windenergieanlage mit einem Rotor mit im wesentlichen horizontaler Achse, einer diesen tragenden Gondel, einem die Gondel um eine vertikale Achse drehbar tragenden Turm und einer den Turm tragenden, in den Meeresboden eingebrachten oder auf diesem ruhenden Gründung.The invention relates to an offshore wind turbine with a rotor with an essentially horizontal axis, one of these supporting gondola, the gondola rotatable about a vertical axis supporting tower and one supporting the tower, in the seabed brought in or resting on this foundation.
Offshore-Windenergieanlagen gewinnen zunehmend an Bedeutung. Es stellt sich dabei das Problem, dass ein Restrisiko einer Kollision großer Schiffe, insbesondere auch Tanker, mit einer solchen Offshore-Windenergieanlage besteht. Ohne besondere Vorsichtsmaßnahmen könnte das Schiff durch die Offshore-Windenergieanlage, besonders auch durch deren Rotorblätter, erheblich beschädigt werden.Win offshore wind turbines increasingly important. The problem arises that a Residual risk of a major collision Ships, especially tankers, with such an offshore wind turbine consists. Without any special precautionary measures, the ship could be driven by the offshore wind turbine, especially damaged by their rotor blades.
Zum Stand der Technik wird auf die
Der Erfindung liegt die Aufgabe zugrunde, eine Offshore-Windenergieanlage zu schaffen, bei der eine Beschädigung eines mit dieser kollidierenden Schiffs ausgeschlossen ist.The invention has for its object a To create an offshore wind turbine that damages a with this colliding ship is excluded.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst, die Unteransprüche geben bevorzugte Ausgestaltungen der Erfindung an.According to the invention, this object is achieved by Features of claim 1 solved the subclaims give preferred embodiments of the invention.
Der Erfindung liegt die Erkenntnis zugrunde, dass eine besondere Gefahr von den sich drehenden Rotorblättern der Windenergieanlage ausgeht, diese werden erfindungsgemäß bei Annäherung eines Schiffs stillgesetzt, die Gondel wird sodann derart um ihre Achse gedreht, dass die Rotorblätter auf der dem sich nähernden Schiff abgewandten Seite des Turms stehen.The invention is based on the knowledge underlying that a particular danger from the rotating rotor blades of the Wind turbine goes out, these are according to the invention when approaching a ship stopped, the gondola is then rotated about its axis that the rotor blades on the approaching Stand ship-facing side of the tower.
Die Offshore-Windenergieanlage kann das sich nähernde Schiff üblicherweise durch Radar erkennen, vorzugsweise aber werden von dem Schiff ausgesendete GPS Positionsdaten mit der eigenen Position verglichen und aus diesen Daten die Annäherung erkannt.The offshore wind turbine can the approaching Ship usually detect by radar, but preferably are emitted by the ship GPS position data compared to and from your own position Dates the approximation recognized.
Der Turm sollte mit Fendern versehen sein, die nach Art eines Airbags ausgebildet sind, sich also bei Annäherung eines Schiffs aufblasen und bei Kontakt mit dem Schiff die Luft langsam abgeben. Diese Maßnahme mindert den Impuls zwischen dem sich, annähernden Schiff und der Offshore-Windenergieanlage. Dabei können derartige Fender ringförmig und in unterschiedlicher Höhe um den Turm herum angeordnet sein, aus den von dem sich annähernden Schiff übersendeten Daten wird die Höhe der Bordkante des Schiffs und damit ermittelt, welcher der Fender aufzublasen ist.The tower should have fenders be, which are designed in the manner of an airbag, so at approach inflate a ship and upon contact with the ship the air hand in slowly. This measure reduces the momentum between the approaching ship and the offshore wind turbine. You can such fenders ring-shaped and at different heights be arranged around the tower, from those transmitted by the approaching ship Data becomes the height the ship's curb and thus determines which of the fenders is to inflate.
Bei einer besonders großen Masse des sich annähernden Schiffs besteht aber auch bei diesen Vorsichtsmaßnahmen noch ein Restrisiko, dass das Schiff die Offshore-Windenergieanlage zerstört und der Turm der Anlage mit Gondel und Rotor auf das Schiff fällt und dieses erheblich beschädigt. Um ein solches Geschehen auszuschließen können zwischen dem Turm und der Gründung oder innerhalb der Gründung eine regelmäßig verriegelte und bei Annäherung eines Schiffs freizugebende Verbindungsstellen vorhanden sein. Werden bestimmte dieser Verbindungsstellen bei Erkennen einer solchen Gefahrensituation schlagartig freigegeben, wird das Schiff mit seiner erheblichen Masse den Turm mit Gondel und Rotorblättern umlegen, und zwar in eine von dem Schiff abgewandte Richtung. Eine Beschädigung des Schiffs ist damit ausgeschlossen.With a particularly large mass of approaching However, even with these precautionary measures there is still a residual risk, that the ship destroys the offshore wind turbine and the Tower of the facility with gondola and rotor falls on the ship and this significantly damaged. To rule out such an event can be between the tower and the foundation or within the foundation one locked regularly and when approaching connection points to be released of a ship are available. Become certain of these connection points upon detection of such a dangerous situation suddenly released, the ship with its considerable Crush the tower with the nacelle and rotor blades, in a direction away from the ship. Damage to the Ship is excluded.
Bei einer Ausbildung einer Offshore-Windenergieanlage, deren Gründung – in an sich bekannter Weise – mit sich an den Meeresboden ansaugenden Saugglocken versehen ist, wird eine Einrichtung zum Lüften der Saugglocken bei Annäherung eines Schiffs vorgeschlagen. Diese Ausgestaltung ermöglicht es, dass die Windenergieanlage durch das Schiff schlicht weggedrückt wird. Vorraussetzung dafür ist es natürlich, dass der Schwerpunkt der Offshore-Windenergieanlage etwa in der Höhe der Bordkante eines großen Schiffs angeordnet ist.When training an offshore wind turbine, their foundation - in familiar way - with suction cups sucking on the sea floor is provided a device for ventilation the suction cups when approaching proposed by a ship. This configuration enables that the wind turbine is simply pushed away by the ship. Prerequisite for this is it natural that the center of gravity of the offshore wind turbine is approximately at the curb of a big one Ship is arranged.
Diese Variante der Erfindung wird anhand einer Zeichnung erläutert. Diese zeigt den unteren Teil einer Offshore-Windenergieanlage.This variant of the invention will explained using a drawing. This shows the lower part of an offshore wind turbine.
