Claims (15)

  1. Schwerkraftfundament für eine Offshore-Struktur, wobei das Schwerkraftfundament umfasst:
    Ein Unterteil zum Untertauchen unter Wasser, wobei das Unterteil eine innere Kammer und eine Vielzahl von äußeren Kammern einschließt, die um die innere Kammer herum angeordnet sind; und gekennzeichnet durch:
    Ein Verteilungssystem für Ballastwasser zum Fluten der Kammern des Unterteils mit Wasser während der Aufstellung des Fundaments;
    wobei das Verteilungssystem für Ballastwasser umfasst: Eine erste Flüssigkeitsverbindung zum Einleiten von Wasser in die innere Kammer; und eine Vielzahl von zweiten Flüssigkeitsverbindungen jeweils zum Durchgang von Wasser von der inneren Kammer zu einer äußeren Kammer; wobei die zweiten Flüssigkeitsverbindungen jeweils einschließen: Einen Auslass in einer äußeren Kammer, wobei sich die äußere Kammer an einer ersten Seite der inneren Kammer befindet; und einen Einlass, der innerhalb der inneren Kammer auf einer höheren Ebene als der Auslass und an einer zweiten Seite der inneren Kammer generell der Position der äußeren Kammer gegenüber liegend positioniert ist.
  2. Schwerkraftfundament, wie in Anspruch 1 beansprucht, wobei die zweiten Flüssigkeitsverbindungen Einlässe aufweisen, die alle auf etwa der gleichen Höhe liegen.
  3. Schwerkraftfundament, wie in Anspruch 1 oder 2 beansprucht, wobei der Einlass für jede der zweiten Flüssigkeitsverbindungen generell der Mitte der äußeren Kammer gegenüber liegend platziert ist, wo sich der jeweilige Auslass befindet.
  4. Schwerkraftfundament, wie in Anspruch 1, 2 oder 3 beansprucht, wobei die Einlässe oberhalb der Höhe der Auslässe um wenigstens ein Viertel einer/eines maximalen Breite oder Durchmessers der inneren Kammer liegen.
  5. Schwerkraftfundament, wie in einem beliebigen vorangehenden Anspruch beansprucht, wobei die erste Flüssigkeitsverbindung eine Verbindung zwischen der inneren Kammer und der Außenseite des Fundaments an einem Punkt unterhalb des Wasserspiegels für das Fundament in einem Schwimmzustand ohne Ballast umfasst.
  6. Schwerkraftfundament, wie in einem beliebigen vorangehenden Anspruch beansprucht, wobei das Unterteil des Schwerkraftfundaments eine symmetrische Anordnung von wenigstens drei äußeren Kammern umfasst.
  7. Schwerkraftfundament, wie in einem beliebigen vorangehenden Anspruch beansprucht, wobei die Höhe von Wänden, welche die inneren und äußeren Kammern teilen und/oder die Höhe von Wänden, welche die äußeren Kammern voneinander teilen so festgelegt ist, dass das Fundament stabil und aufrecht bleibt, wenn das Ballastwasser die äußeren Kammern bis zu den Oberseiten der Wände füllt.
  8. Schwerkraftfundament, wie in einem beliebigen vorangehenden Anspruch beansprucht, wobei das Fundament eine flache Bodenplatte mit einem Sockelmantel einschließt, der sich abwärts vom Boden weg erstreckt.
  9. Offshore-Windturbinenstruktur, die ein Schwerkraftfundament, wie in einem beliebigen vorangehenden Anspruch beansprucht, inkorporiert.
  10. Verfahren zur Aufstellung eines Offshore-Schwerkraftfundaments, wobei das Schwerkraftfundament umfasst:
    Ein Unterteil zum Untertauchen unter Wasser, wobei das Unterteil eine innere Kammer und eine Vielzahl von äußeren Kammern einschließt, die um die innere Kammer herum angeordnet sind; und
    Ein Verteilungssystem für Ballastwasser zum Fluten der Kammern des Unterteils mit Wasser während der Aufstellung des Fundaments;
    wobei das Verteilungssystem für Ballastwasser umfasst: Eine erste Flüssigkeitsverbindung zum Einleiten von Wasser in die innere Kammer; und eine Vielzahl von zweiten Flüssigkeitsverbindungen jeweils zum Durchgang von Wasser von der inneren Kammer zu einer äußeren Kammer; wobei die zweiten Flüssigkeitsverbindungen einschließen: Einen Auslass in einer äußeren Kammer, wobei sich die äußere Kammer an einer ersten Seite der inneren Kammer befindet; und einen Einlass, der innerhalb der inneren Kammer auf einer höheren Ebene als der Auslass und an zweiter Seite der inneren Kammer generell der Position der äußeren Kammer gegenüber liegend positioniert ist.
    wobei das Verfahren umfasst: Füllen der inneren Kammer mit Wasser, um dadurch Wasser zu erlauben entlang der zweiten Flüssigkeitsverbindungen vom Einlass zum Auslass zu fließen, um alle der Kammern mit Wasser zu fluten.
  11. Verfahren, wie in Anspruch 10 beansprucht, das die Aufstellung eines Schwerkraftfundaments, wie in einem beliebigen der Ansprüche 1 bis 9 beansprucht, umfasst.
  12. Verfahren, wie in Anspruch 10 oder 11 beansprucht, wobei das Fundament direkt auf dem Meeresgrund, ohne irgendwelche vorherige Vorbereitung, wie beispielsweise Ausbaggern oder die Installation einer Nivellierungslage aus körnigem Material von, installiert wird.
  13. Verfahren, wie in Anspruch 10, 11 oder 12 beansprucht, wobei das Fundament eine flache Bodenplatte mit einem Sockelmantel einschließt, der sich abwärts von der Basis weg erstreckt und das Verfahren das Eigengewicht des Fundaments benutzt, um den Sockelmantel in die Meeresgrundböden zu stoßen.
  14. Verfahren, wie in einem beliebigen der Ansprüche 10 bis 13 beansprucht, umfassend: Installation einer Offshore-Struktur auf dem Fundament im Anschluss an den Ballastierungsvorgang.
  15. Verfahren, wie in Anspruch 14 beansprucht, wobei die Offshore-Struktur eine Windturbine ist.
