Abstract

A connector for risers on offshore well drilling platforms locks the spigot end of one riser length to the socket end of the next riser length by two pairs of clamping clips which can be swivelled around the socket parts of ancillary parallel pipes. The other ends of the clips are slotted and can be clamped together by hinged bolts so that the conical inner periphery of the clips holds conical collars on spigot and socket of the riser clamped together. Such a connector can be quickly uncoupled. It allows an easy check that it is securely closed.

Description

Die Erfindung betrifft eine Steckverbindung für Steigrohr-The invention relates to a plug connection for riser

leitungen (Riser) bei off-shore-Bohrungen nach Kohlenwasserstoffen von einer schwimmenden Bohreinheit aus.Lines (risers) in offshore drilling for hydrocarbons from a floating drilling unit.

Bekannterweise haben Riser die Aufgabe, das Bohrgestänge, welches sich in ihnen befindet, zu führen und vor äußeren Einflüssen zu schützen sowie die Bohrflüssigkeit zur schwimmenden Bohreinheit zurückzuführen.As is known, risers have the task of the drill pipe, which is located in them, to lead and to protect from external influences as well as the Return drilling fluid to the floating drilling unit.

Es sind eine Reihe von Riser-Steckverbindungen bekannt, so ist z.B. vorgeschlagen worden, mehrere Verriegelungsspannhebel auf dem Umfang des Muffenteiles anzuordnen und sie über entsprechend angeordnete bundartige Ansätze zu verspannen.A number of riser connectors are known, e.g. has been proposed several locking levers on the circumference of the sleeve part to be arranged and to brace them using appropriately arranged collar-like approaches.

Es sind auch Rohrsysteme (Marine-Riser) bekannt, die aus einzelnen Abschnitten (Riser-Joints) bestehen, die durch biegesteife Verbindungselemente oder Verschraubungen miteinander verbunden sind und lediglich am oberen oder unteren Teil je eine flexible Verbindung aufweisen (US-PS 3,601,187).There are also pipe systems (marine riser) known, which consist of individual Sections (riser joints) consist of rigid fasteners or Screw connections are interconnected and only at the top or bottom Part each have a flexible connection (US Pat. No. 3,601,187).

Es ist auch bereits vorgeschlagen worden, die Einzelabschnitte eines Rohrsystems durch bewegliche Kugelgelenke zu verbinden (DE-PS 2518 604).It has also already been suggested that the individual sections of a To connect the pipe system by moving ball joints (DE-PS 2518 604).

Aufgabe der Erfindung ist es, eine Riser-Steckverbindung für off-shore-Bohrungen zu schaffen, die schnell lösbar ist und deren sicher geschlossener Zustand leicht kontrollierbar ist.The object of the invention is to provide a riser connector for off-shore boreholes to create that can be quickly released and its securely closed state easily is controllable.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 angeführten Merkmale gelöst.According to the invention, this object is achieved by the characteristics of Claim 1 cited features solved.

Die weitere Ausbildung des Erfindungsgegenstandes geht aus den Merkmalen der Unteransprüche hervor.The further development of the subject matter of the invention is based on the features of the subclaims.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß die Steckverbindung eine technisch einfache Lösung für eine schnell lösbare Verbindung darstellt und gegenüber den bekannten Verbindungen eine bessere#Kontrolle auf den sicher geschlossenen Zustand ermöglicht.The advantages achieved by the invention are that the connector represents a technically simple solution for a connection that can be released quickly and Compared to the known connections a better # control on the securely closed State enables.

In den beigefügten Zeichnungen ist eine Ausführungsform einer erfindungsgemäßen Riser-Steckverbundung schematisch dargestellt.In the accompanying drawings there is an embodiment of one according to the invention Riser connector shown schematically.

Es zeigen: Fig. 1 eine Vorderansicht einer Rohrverbindung im Schnitt, Fig. 2 eine Draufsicht auf Fig. 1 im Schnitt auf der Linie A-B.1 shows a front view of a pipe connection in section, Fig. 2 is a plan view of Fig. 1 in section on the line A-B.

In Fig. 2 sind Verriegelungsspannbügel 1 und 2 um Nebenleitungen 3 und 4 nach außen quer zur Achse der Steckverbindung 5 schwenkbar gelagert. Die Verriegelungsspannbügel 1 und 2 sind mit konischen Ausnehmungen 6 (Fig. 1) versehen, die mit konischen Flächen 7 und 8 versehene Bunde 9 und 10 des Muffenteiles 11 und des Einsteckendes 12 umfassen. In verriegeltem Zustand werden die Verriegelungsspannbügel 1 und 2 durch schwenkbare Spannbolzen 13 gehalten.In FIG. 2, locking clamps 1 and 2 are around secondary lines 3 and 4 pivoted outwardly transversely to the axis of the plug connection 5. The locking clamps 1 and 2 are provided with conical recesses 6 (Fig. 1) with conical surfaces 7 and 8 provided collars 9 and 10 of the socket part 11 and the male end 12 comprise. In the locked state, the locking clamps 1 and 2 are pivotable Clamping pin 13 held.

Die Lagerung 15 und 16 der Verriegelungsspannbügel 1 und 2 erfolgt in einer Ebene um die Muffenteile 14 der Steckverbindungen der Nebenleitungen 3 und 4.The bearings 15 and 16 of the locking clamps 1 and 2 he follows in a plane around the socket parts 14 of the plug connections of the secondary lines 3 and 4.

Die Bunde 9 und 10 sind sowohl ffflr die Nebenleitungen 3 und 4 als auch für die Nebenleitungen 17 bei 20 ausgenommen.The bundles 9 and 10 are both for the secondary lines 3 and 4 as also excluded for the secondary lines 17 at 20.

Die Verriegelungsspannbügel 1 und 2 sind im Bereich der Spannbolzen 13 für die Muffen 18 der Steckverbindungen der Nebenleitungen 17 bei 19 ausgenommen.The locking clamps 1 and 2 are in the area of the clamping bolts 13 for the sleeves 18 of the plug connections of the secondary lines 17 at 19 excepted.
