Abstract

Drilling and production platforms must be fixedly anchored in the seabed. To achieve this, it is proposed according to the invention to establish a gravity-based foundation by rigidly connecting foundation bodies (5 to 7) to the legs (2 to 4) of the standing structure. This measure makes transport to the site and the lowering process much easier. One embodiment of a platform with a gravity-based foundation is shown in the drawing. <IMAGE>

Description

Bohr- und Produktionsplattform Drilling and production platform

Die Erfindung bezieht sich auf eine Bohr- und Produktionsplattform, welche auf drei Beinen aufgeständert ist und die Beine auf GrUndungskörpern aufgelagert sind.The invention relates to a drilling and production platform, which is raised on three legs and the legs are supported on foundations are.

Beine von Plattformen werden über Grtlndungskörper auf den Meeresboden aufgelagert. Die Verbindung der Beine mit den Grundungskörpern ist meist gelenkig, um Zusatzkräfte aus der Verformung und Bodenunebenheiten zu vermeiden. Solche Gelenke hingegen sind aufwendig und gestalten den Transport des Bohrturmes zur Bohrstelle schwierig.Legs of platforms are over foundations on the ocean floor superimposed. The connection between the legs and the foundations is usually articulated, to avoid additional forces from deformation and uneven floors. Such joints however, they are complex and make the transport of the derrick to the drilling site difficult.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Schwierigkeiten auszuräumen und die Struktur zu vereinfachen.The invention is therefore based on the object of these difficulties clear out and simplify the structure.

Gelöst wird diese Aufgabe dadurch, daß die GrUndungskörper starr mit den Beinen verbunden sind.This object is achieved in that the base body is rigid with the legs are connected.

Dadurch wird die Verbindung vom Bein zum GrUndungskörper sicherer und billiger. Der Seetransport von einem Bau Dock zum Feld ist wesentlich einfacher, da die GrUndungskdrper gegenüber den Beinen keine Relativbewegungen ausrühren können.This makes the connection from the leg to the base structure more secure and cheaper. Sea transport from a construction dock to the field is much easier, since the foundations cannot move relative to the legs.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An exemplary embodiment is shown in the drawing.

Eine Plattform 1 ist Uber eine aus drei Beinen 2, 3, 4 in Fachwerkbauweise ausgeführte Tragkonstruktion auf dem Meeresboden abgestützt. Die Krafteinleitung von den Beinen 2 bis 4 auf den Meeresboden erfolgt durch Oründungskörper 5 bis 7. Die Gründungskörper 5 bis 7 sind erfindungsgemäß starr mit der Fachwerkkonstruktion der Beine 2 bis 4 verbunden. Die Gründungskörper 5 bis 7 werden nach dem Absenken mit Fülimaterial (Kies 8) ausgegossen.A platform 1 is about one of three legs 2, 3, 4 in a half-timbered construction Executed supporting structure supported on the seabed. The introduction of force from legs 2 to 4 to the sea floor occurs through orifice bodies 5 to 7. According to the invention, the foundation bodies 5 to 7 are rigid with the framework construction of legs 2 to 4 connected. The foundation bodies 5 to 7 are after the lowering filled with filling material (gravel 8).
