Description

Die Erfindung betrifft autark schwimmfähige Schwergewichtsgründungen zur Verbindung mit einer schwimmfähigen Offshore-Anlage zur Umwandlung von Windenergie oder Sonnenenergie in elektrische Energie mit einer Massivplatte aus Beton, Stahlbeton, einem Verbund mit Beton oder einer Kombination davon, wenigstens einer befüllbaren Kammer und Befestigungsmitteln zur Verbindung eines Tragwerks in Verbindung mit einem Turm einer Windkraftanlage oder mit wenigstens einem Träger mit einer Solaranlage, wobei die schwimmende Schwergewichtsgründung leere Kammern und die abgesenkte Schwergewichtsgründung gefüllte Kammern aufweist.The invention relates to self-sufficient floating heavyweight foundations for connection with a floating offshore installation for converting wind energy or solar energy into electrical energy with a solid slab of concrete, reinforced concrete, a composite with concrete or a combination thereof, at least one fillable chamber and fastening means for connecting a supporting structure in connection with a tower of a wind power plant or with at least one support with a solar plant, the floating gravity foundation having empty chambers and the lowered gravity foundation having filled chambers.

Zur Verankerung eines in der offenen See schwimmenden Tragwerks mit einer Windkraftanlage, Servicestation oder Konverterstation sind in den Boden der See einzubringende Pfähle bekannt. Dazu können Bohrpfähle als in den Boden gebohrte Stahlrohre eingesetzt werden. Die Erde wird aus dem Innern des Rohres entfernt und Beton in den durch das Rohr ausgebildeten Hohlraum eingebracht. Eine derartige Lösung ist unter anderem durch die Druckschrift DE 196 41 422 A1 als Verfahren zum Herstellen eines Betonbohrpfahles bekannt. Eine andere Möglichkeit sind sogenannte Rammpfähle, wie sie beispielsweise durch die Druckschrift DE 28 23 269 A1 als Stahlrammpfähle bekannt sind. Der Einsatz von Pfählen führt bei deren Platzierung im Boden der See insbesondere zu einer starken Geräuschbildung.For anchoring a structure floating in the open sea with a wind power plant, service station or converter station, piles to be introduced into the sea floor are known. For this purpose, bored piles can be used as steel pipes drilled into the ground. The earth is removed from the interior of the pipe and concrete is poured into the cavity formed by the pipe. One such solution is through the publication DE 196 41 422 A1 known as a method of making a concrete bored pile. Another possibility are so-called driven piles, such as those described in the publication DE 28 23 269 A1 known as steel driven piles. The use of piles, when placed in the bottom of the sea, leads to a particularly high level of noise.

Durch die Druckschrift DE 10 2009 044 278 A1 ist ein Schwimmfundament mit verbesserter Abspannung bekannt. Das Schwimmfundament weist Anker auf, die vertikal unterhalb von Anschlussstellen eines Schwimmtragwerks angeordnet sind. Dazu sind diese ortsfest in horizontalen Abständen zueinander am Meeresboden angeordnet. Die Anker sind vorzugsweise Ballastkörper in Form von Schwergewichtsfundamenten, die nicht schwimmfähig sind.Through the print DE 10 2009 044 278 A1 a floating foundation with improved bracing is known. The floating foundation has anchors which are arranged vertically below connection points of a floating structure. For this purpose, these are fixedly arranged at horizontal distances from one another on the sea floor. The anchors are preferably ballast bodies in the form of heavyweight foundations that are not buoyant.

Schwimmende Auftriebskörper in Verbindung mit Ankern für Windkraftanlagen in der offenen See ist beispielsweise durch die Druckschrift GB 2 378 679 A bekannt. Das dazu realisierte Schwimmfundament besteht aus mehreren Auftriebskörpern, die über radiale Stahlstreben mit dem Turm der Windkraftanlage verbunden sind. Die Stahlstreben sind in Draufsicht kreuzförmig angeordnet und untereinander nicht verbunden. Treten an den radialen Stahlstreben des Bauwerks Biegekräfte auf, führen diese zu hohen Biegemomenten.Floating buoyancy in connection with anchors for wind turbines in the open sea is for example through the publication GB 2,378,679 A known. The floating foundation implemented for this purpose consists of several buoyancy bodies that are connected to the tower of the wind turbine via radial steel struts. The steel struts are arranged in a cross shape in plan view and are not connected to one another. If bending forces occur on the radial steel struts of the structure, these lead to high bending moments.

Ein Schwergewichtsanker für Offshore-Anlagen ist durch die Druckschrift US 4 296 706 A bekannt. Dieser besitzt einen befüllbaren Behälter, der zum Absenken durch Flutung mit Wasser befüllbar ist. Das Wasser wird durch Ballast ausgetauscht, so dass der Schwergewichtsanker auf dem Meeresboden realisiert ist. An diesem können mehrere weitere Behälter angeordnet sein, so dass der Transport zu einem neuen Ort leicht möglich ist. Abspannmittel für eine Offshore-Anlage und deren Befestigung sind nicht näher ausgeführt.A heavyweight anchor for offshore installations is through the publication U.S. 4,296,706 A known. This has a fillable container that can be filled with water for lowering by flooding. The water is exchanged by ballast, so that the heavyweight anchor is realized on the sea floor. Several further containers can be arranged on this, so that transport to a new location is easy. Anchoring means for an offshore installation and their fastening are not detailed.

Die Druckschrift DE 10 2015 208 162 A1 offenbart einen schwimmfähigen Schwergewichtsanker zur Verankerung eines in der offenen See schwimmenden Tragwerks mit einer Windkraftanlage, Servicestation oder Konverterstation. Der Schwergewichtsanker weist eine Massivplatte, mehrere flutbare Kammern und Befestigungsmittel für Auftriebskörper des Tragwerks auf, wobei der schwimmende Schwergewichtsanker nicht geflutete Kammern, der sich absenkende Schwergewichtsanker teilgeflutete Kammern und der abgesenkte Schwergewichtsanker geflutete Kammern aufweist. Der schwimmfähige Schwergewichtsanker ist ein monolithisch ausgebildeter Schwergewichtsanker.The pamphlet DE 10 2015 208 162 A1 discloses a buoyant heavyweight anchor for anchoring a structure floating in the open sea with a wind turbine, service station or converter station. The heavyweight anchor has a solid plate, several floodable chambers and fastening means for buoyancy bodies of the structure, the floating heavyweight anchor not flooded chambers, the sinking heavyweight anchor partially flooded chambers and the lowered heavyweight anchor flooded chambers. The buoyant heavyweight anchor is a monolithic heavyweight anchor.

Der im Patentanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, eine Offshore-Anlage einfach ortsfest zu verankern.The invention specified in claim 1 is based on the object of simply anchoring an offshore installation in a stationary manner.

Diese Aufgabe wird mit den im Patentanspruch 1 aufgeführten Merkmalen gelöst.This object is achieved with the features listed in claim 1.

Die autark schwimmfähigen Schwergewichtsgründungen zur Verbindung mit einer schwimmfähigen Offshore-Anlage zur Umwandlung von Windenergie oder Sonnenenergie in elektrische Energie mit einer Massivplatte aus Beton, Stahlbeton, einem Verbund mit Beton oder einer Kombination davon, wenigstens einer befüllbaren Kammer und Befestigungsmitteln zur Verbindung eines Tragwerks in Verbindung mit einem Turm einer Windkraftanlage oder mit wenigstens einem Träger mit einer Solaranlage, wobei die schwimmende Schwergewichtsgründung leere Kammern und die abgesenkte Schwergewichtsgründung gefüllte Kammern aufweist, zeichnen sich insbesondere dadurch aus, dass die Offshore-Anlage einfach ortsfest verankerbar ist.The self-sufficient floating heavyweight foundations for connection with a floating offshore system for converting wind energy or solar energy into electrical energy with a solid slab of concrete, reinforced concrete, a composite with concrete or a combination thereof, at least one fillable chamber and fasteners for connecting a supporting structure in connection with a tower of a wind power plant or with at least one carrier with a solar plant, the floating heavyweight foundation having empty chambers and the lowered heavyweight foundation having filled chambers, are characterized in particular by the fact that the offshore installation can easily be anchored in a stationary manner.

Dazu besitzt die Massivplatte Ankerplatten mit jeweils einem Befestigungsmittel zur Verbindung mit wenigstens einem Abspannmittel zur Verbindung mit dem Tragwerk. Die Ankerplatte weist wenigstens eine vertikal orientierte oder im wesentlichen vertikal orientierte erste Platte mit dem Befestigungsmittel und mindestens eine horizontal oder im wesentlichen horizontal orientierte zweite Platte auf. Weiterhin befindet sich die erste Platte wenigstens teilweise in der Massivplatte, so dass die zweite Platte von einem Bereich der Massivplatte überdeckt ist. Damit sind die ersten Platten der Ankerplatten Zugkräfte des Tragwerks weiterleitende erste Platten und die zweiten Platten der Ankerplatten die aus den Zugkräften resultierenden Druckkräfte auf die Massivplatte ausübende zweiten Platten.For this purpose, the solid plate has anchor plates, each with a fastening means for connection to at least one anchoring means for connection to the supporting structure. The anchor plate has at least one vertically oriented or essentially vertically oriented first plate with the fastening means and at least one horizontally or essentially horizontally oriented second plate. Furthermore, the first plate is at least partially in the solid plate, so that the second plate is covered by an area of the solid plate. Thus, the first plates of the anchor plates are first plates which transmit tensile forces of the structure, and the second plates of the anchor plates are the second plates exerting pressure forces on the solid plate resulting from the tensile forces.

Die autark schwimmfähige Schwergewichtsgründung ist damit vor Ort schwimmfähig und senkt sich durch Flutung der Kammern selbst ab. Bei eventuell vorhandenen Strömungen ist dieser dabei nur in Position zu halten. Das Absenken kann dabei vorteilhafterweise durch das Fluten gezielt gesteuert erfolgen. Die gefluteten Kammern erhöhen natürlich das Gewicht der Schwergewichtsgründung auf dem Boden der See.The self-sufficient, buoyant heavyweight foundation is therefore buoyant on site and sinks itself when the chambers are flooded. If there are any currents, this only needs to be held in position. The lowering can advantageously take place in a controlled manner by the flooding. The flooded chambers naturally add to the weight of the heavyweight foundation on the bottom of the sea.

Die Herstellung kann vollständig an Land erfolgen. Daraufhin ist diese einfach durch Schleppen selbst oder mittels eines Transportschiffes oder in einem Trockendock zum Ort der Platzierung der Offshore-Anlage transportierbar. Die Schwergewichtsgründung ist bei Störungen oder bei Nichtbedarf leicht wieder vom Boden der See zu entfernen. Die Kammern sind dazu einfach mit Luft zu befüllen, so dass der Schwergewichtsanker einfach aufschwimmt.Production can be done entirely on land. This can then be easily transported to the location of the offshore installation by towing it itself or by means of a transport ship or in a dry dock. The heavyweight foundation can easily be removed from the bottom of the sea in the event of disruptions or when it is not needed. The chambers are simply filled with air so that the heavyweight anchor simply floats up.

Zur Befestigung eines Tragwerks, welches sich im Wesentlichen Unterwasser befindet und Auftriebskörper aufweist, sind die ersten Platten der Ankerplatten über jeweils ein Befestigungsmittel zur Verbindung mit wenigstens einem Abspannmittel zur Verbindung mit dem Tragwerk versehen. Durch die Auftriebskörper werden die Abspannmittel und damit die ersten Platten der Ankerplatten auf Zug beansprucht. Die zweite horzontal oder im Wesentlichen horizontal orientierte Platte in oder an der Massivplatte drückt dadurch auf die Massivplatte. Die Zugkräfte der Abspannmittel werden durch die Ankerplatten quasi in auf die Massivplatte als Betonkörper wirkende Druckkräfte gewandelt.To attach a structure which is essentially underwater and has buoyancy bodies, the first plates of the anchor plates are each provided with a fastening means for connection to at least one anchoring means for connection to the structure. The anchoring means and thus the first plates of the anchor plates are subjected to tensile stress by the float. The second horizontally or essentially horizontally oriented plate in or on the solid plate thereby presses on the solid plate. The tensile forces of the anchoring means are converted by the anchor plates into pressure forces acting on the solid slab as a concrete body.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen 2 bis 12 angegeben.Advantageous embodiments of the invention are given in claims 2 to 12.

Die erste Platte und die zweite Platte sind nach der Weiterbildung des Patentanspruchs 2 direkt und/oder über wenigstens eine Verbindungsplatte miteinander verbunden.According to the development of claim 2, the first plate and the second plate are connected to one another directly and / or via at least one connecting plate.

An der ersten Platte befindet sich nach der Weiterbildung des Patentanspruchs 3 wenigstens eine quer zur ersten Platte und winklig zur zweiten Platte angeordnete dritte Platte. Diese dritte Platte leitet die Zugkraft eines mit einem Winkel größer 0 und kleiner 90° in Bezug zur Massivplatte angeordneten Abspannmittels anteilig als Druckkraft zur Mitte der Massivplatte.According to the development of claim 3, there is at least one third plate arranged transversely to the first plate and at an angle to the second plate on the first plate. This third plate conducts the tensile force of an anchoring means arranged at an angle greater than 0 and less than 90 ° in relation to the solid plate proportionally as a compressive force to the center of the solid plate.

Die Massivplatte mit den Ankerplatten und die Kammer sind nach der Weiterbildung des Patentanspruchs 4 monolithisch ausgebildet.The solid plate with the anchor plates and the chamber are monolithic according to the development of claim 4.

Die Kammer besitzt nach der Weiterbildung des Patentanspruchs 5 Zwischenwände. Die Schwergewichtsgründung kann gezielt sicher abgesenkt werden.According to the development of claim 5, the chamber has partition walls. The heavyweight foundation can be safely lowered in a targeted manner.

Die Schwergewichtsgründung weist nach der Weiterbildung des Patentanspruchs 6 eine zentrale Kammer und symmetrisch um die zentrale Kammer angeordnete und gleich gestaltete Kammern auf der Massivplatte auf. Damit können die Abspannmittel zwischen den Kammern geführt werden.According to the development of patent claim 6, the heavyweight foundation has a central chamber and chambers of the same shape arranged symmetrically around the central chamber on the solid plate. The anchoring means can thus be guided between the chambers.

Die Kammer besitzt nach der Weiterbildung des Patentanspruchs 7 wenigstens einen Einlass und mindestens einen Auslass zum Befüllen der Kammer, wobei der Einlass am Boden der Kammer und der Auslass entweder an der Decke oder in der Decke angeordnet sind. Bei der Befüllung kann im Wesentlichen der gesamte Raum der Kammer mit einem Füllkörper versehen werden. Beim Absenken wird beispielsweise Wasser in die Kammer eingeleitet, welches nach dem Absenken durch Sand ersetzt wird. Dieser wird in die Kammer gedrückt, wobei gleichzeitig Wasser entweicht. Die Anordnung von Einlass und Auslass verhindern ein ansonsten auftretenden Schüttkegel.According to the development of claim 7, the chamber has at least one inlet and at least one outlet for filling the chamber, the inlet being arranged on the floor of the chamber and the outlet either on the ceiling or in the ceiling. When filling, essentially the entire space of the chamber can be provided with a filler body. When lowering, for example, water is introduced into the chamber, which is replaced by sand after lowering. This is pressed into the chamber and water escapes at the same time. The arrangement of inlet and outlet prevent an otherwise occurring cone of material.

Die Schwergewichtsgründung weist nach der Weiterbildung des Patentanspruchs 8 Erdspieße auf. Diese dringen in den Boden ein und verringern die Gefahr eines Gleitens der Schwergewichtsgründung auf dem Boden.The heavyweight foundation has 8 ground spikes according to the development of patent claim. These penetrate the ground and reduce the risk of the heavyweight foundation sliding on the ground.

Die Ankerplatte besitzt nach der Weiterbildung des Patentanspruchs 9 im Querschnitt eine umgekehrte T-Form, wobei der Schenkel die erste Platte und der Querbalken die zweite Platte sind.According to the development of claim 9, the anchor plate has an inverted T-shape in cross section, the leg being the first plate and the crossbeam being the second plate.

Die Massivplatte der Schwergewichtsgründung besitzt nach der Weiterbildung des Patentanspruchs 10 eine mehreckige, beispielsweise quadratische, Grundfläche. In den Eckbereichen und wenigstens in den mittleren Bereichen der Seiten befinden sich Ankerplatte, so dass vertikal und schräg verlaufende Abspannmittel mit den Ankerplatten verbindbar sind.According to the development of claim 10, the solid slab of the heavyweight foundation has a polygonal, for example square, base. Anchor plates are located in the corner areas and at least in the middle areas of the sides, so that anchoring means running vertically and at an angle can be connected to the anchor plates.
