Abstract

A ring shape for opening and closing in a floating position encircles structures protruding from the water like towers. Its position in the water is transferred onto a structure to be transported by means of multiple pulling ropes. A pontoon is lifted and deposited by means of ballast procedures. An Independent claim is also included for a method for transporting and installing offshore wind energy plants.

Description

Es ist von jeher von Interesse, für Offshore-Standorte bestimmte Konstruktionen möglichst weitgehend vorgefertigt installieren zu können. Sowohl der Transport von in ihrem Schwerpunkt unter oder im Bereich eines Hebepontons befindlichen Konstruktionen (WO 99/22985), als auch die Bewegung weitestgehend fertig gestellter Windenergieanlagen mittels Schwimmkran (EP 1 101 935 A2) sind bekannt. It has always been of interest to design certain structures for offshore locations if possible to be able to install largely prefabricated. Both the transportation of in their Focus on structures located under or in the area of a lifting pontoon (WO 99/22985), as well as the movement of largely completed wind turbines Floating crane (EP 1 101 935 A2) are known.

Vorteilebenefits

Die hier vorgestellte Methode löst diese Vorgabe für turmartige Konstruktionen, die zum einen von herkömmlichen Transportpontons nicht in stabiler Lage bewegt werden können, und deren Gewicht zum anderen eine Kranung nicht oder nur unter unverhältnismäßigem wirtschaftlichem Aufwand ermöglicht. The method presented here solves this requirement for tower-like constructions that are used for one cannot be moved in a stable position by conventional transport pontoons, and on the other hand, the weight of a crane is not or only disproportionately enables economic effort.

Dazu wird für den gesamten Installationsvorgang die verhältnismäßig stabile Wasserlage großer Arbeitspontons genutzt. Unter äußeren Bedingungen, die Arbeiten mit zu hebenden Lasten nicht mehr zulassen, kann diese Methode noch durchgeführt werden. In addition, the relatively stable water position is for the entire installation process large work pontoons used. Under external conditions, work with to be lifted This method can still be carried out if loads are no longer permitted.

Unter Einrichtung einer entsprechenden Infrastruktur können nach diesem System Offshore- bestimmte Windenergieanlage an Land, vorzugsweise direkt am Tiefwasserbecken montiert werden. Dort aufgenommen wird sie zum Bestimmungsort verschleppt, und kann über dem entsprechend aufbereitetem Untergrund in der endgültigen Position abgesetzt werden. With the establishment of an appropriate infrastructure, offshore certain wind turbines on land, preferably mounted directly on the deep-water pool become. Picked up there, it will be towed to its destination and can be carried over according to the prepared surface in the final position.

Funktionsweisefunctionality

Das Prinzip der Anlage beruht auf der Aufnahme einer aufrecht stehenden turmartigen Konstruktion, z. B. einer Windenergieanlage durch einen sie an der Wurzel des Turmes ringförmig umschließenden tauchfähigen Ponton. Dieser wird in abgesenktem, aber noch schwimmendem Zustand durch eine Vielzahl von Tragseilen mit der Bodenplatte, der Tripod- Konstruktion, o. ä. der Windenergieanlage verbunden. Mit Lenzen der Ballasttanks wird die Windenergieanlage angehoben. Es entsteht eine schwimmfähige Einheit, die vom Verladeort zum designierten Standort der Windenergieanlage verschleppt wird. Dort in genaue Position gebracht, wird die Einheit durch Fluten der Ballasttanks abgesenkt und die Tragseile gelöst. The principle of the system is based on the inclusion of an upright tower-like Construction, e.g. B. a wind turbine by one at the root of the tower circular submersible pontoon. This is lowered, but still floating state through a variety of suspension cables with the base plate, the tripod Construction, or the like of the wind turbine connected. With ballast tanks, the Wind turbine raised. A floating unit is created, from the place of loading is dragged to the designated location of the wind turbine. There in exact position the unit is lowered by flooding the ballast tanks and the suspension cables are released.

Proportion und Bausweise des PontonsProportion and construction of the pontoon

Die Verdrängung des Ringponton ist entsprechend dem Gesamtgewicht der Windenergieanlage und der notwendigen Ballasttonnage ausgelegt. Der Ponton ist dabei der Art konstruiert, dass er über eine Scharniertechnik in schwimmendem Zustand entriegelt, geöffnet und geschlossen werden kann (Abb. 1a) & b)), um so den Turm zu umschließen, beziehungsweise sich von ihm zu lösen. Denkbar sind dabei auch Lösungen, wonach ein solcher Ringponton aus trennbaren, mehreren gegebenenfalls gleichartigen Elementen zusammengesetzt ist. The displacement of the ring pontoon is designed according to the total weight of the wind turbine and the necessary ballast tonnage. The pontoon is constructed in such a way that it can be unlocked, opened and closed in a floating state by means of a hinge technology ( Fig. 1a) & b)), so as to enclose the tower or to detach from it. Solutions are also conceivable, according to which such a ring pontoon is composed of separable, several possibly similar elements.

Je besser die Formgebung des Unterwasserschiffs des Ringpontons im Bereichs des inneren Rings der Art von Turmwurzel und Bodenplatte o. ä. der Windenergieanlage entspricht, mit desto geringerem Tiefgang kann die komplette Einheit bewegt werden - z. B. in relativ flachen Hafengewässern. The better the shape of the underwater ship of the ring pontoon in the area of the inner one Rings corresponds to the type of tower root and base plate or the like of the wind turbine, with the less draft the entire unit can be moved - e.g. B. in relatively flat Port waters.

Art und Aufgabe der SeilführungenType and task of the rope guides

Die Tragseile führen zu der Bodenplatte o. ä. der Windenergieanlage im geeigneten Winkel nach unten durch den Ponton hindurch. Neben der reinen Lastaufnahme erfüllen sie dazu die Aufgabe, "kurz" eingestellt die Ladung in flachem Wasser aufzunehmen, "länger" eingestellt die Ladung in tiefer gehängtem Zustand entsprechend der Fahrwassertiefe transportieren zu können, und sie, "beliebig verlängert", am designierten Standort bis kurz über Grund ablassen zu können, so dass die Tauchtiefe der Anlage in Addition ausreicht, die Ladung absetzen zu können (Abb. 2a)-c)). The suspension cables lead to the base plate or the like of the wind turbine at a suitable angle down through the pontoon. In addition to the mere load pick-up, they fulfill the task of "set" shortly to take the load in shallow water, set "longer" to be able to transport the load in a lower hanging state according to the fairway depth, and "extended" to the designated location up to to be able to drain briefly above the ground so that the depth of the system in addition is sufficient to be able to deposit the load ( Fig. 2a) -c)).

Gelangt durch die Bauart der Windenergieanlage oder durch ihre Ladeposition bedingt ihr Schwerpunkt so weit nach oben, dass durch äußere Einflüsse eine instabile Lage entstehen könnte, so kann die Windenergieanlage durch Zugseile nach unten abgespannt werden, welche von einer weiter oben am Turm angeschlagenen Manschette schräg nach unten auf das Pontondeck führen. Die stets stabile Wasserlage eines derartigen Pontons wird so gleichmäßig und direkt auf die aufgenommene Ladung übertragen. It depends on the design of the wind turbine or its loading position Center of gravity so high that an unstable situation arises due to external influences could, the wind turbine can be braced down by pulling ropes, which from a cuff attached to the tower further up at an angle downwards lead the pontoon deck. The always stable water position of such a pontoon is so evenly and directly transferred to the loaded load.

Werden Trag- und gegebenenfalls Zugseile über zentral gesteuerte hydraulische Zylinder gehalten, ist so ein dynamischer Ausgleich von Wind- und Welleneinflüssen möglich, was den wetterbedingten Einsatzbereich weiter vergrößert. Are suspension cables and, if necessary, traction cables via centrally controlled hydraulic cylinders held, a dynamic compensation of wind and wave influences is possible, what the weather-related area of application is further enlarged.
