Abstract

Et koblingsscykke (10) av patrontypen omfatter et avre legeme (16) med et antall patronsegmenter (52), og en kamrlng (64) som er bevegelig i fortiold til det avre legemet (16) for å bevege patronsegmentene (52) i en avtagbar for- bindelse med en havbunnsbrønnhode (14). Kanuringen (64) og patronsegmentene (52) har sett av kamflater. Et første sett (86, 92) samvirker for é svinge patronsegmentene (52) inn- ledningsvis mot brønnhodet (14), mens et andre sett (96, 104) tjener til å presse patronsegmentene (52) ytterligere i den hensikt å Iclemme koblingsstykket (10) fast til havbunns- bronnhodet (14). Når det andre kamflatesettet (96, 104) er i funksjon, virker det første settet (86, 92) iltke lenger for a svinge patronsegnientcne, slik at kraftbehovet for A presse ,« patronsegmentene (52) i fastklemmende inngrep reduseres til bare ett sett om gangen, selv om begge settene i fellesskap bidrar til A holde patronsegmentene i fastklemmende inngrep med brønnhodet etter at endelig inngrep er opprettet. Kob- lingsstykket utmerker seg ytterligere ved - for det første - at ett sett (86, 92) kamflater tjener til A holde patron- segmentene (52) konisk orientert for A lette posisjonering av koblingsstykKet (10) over brønnhodet (14), og - for det andre - sammen med komplementære anslag (92, 94) A danne en belastningsbane (pil 122) mellom patronsegmentene (52) og det ovre legemet (16), slik at eventuell belastning på koblingsstykket (10) mens det anbringes i brønnhodet (14) vil bli overført til det øvre legemet. Organ for aktivering av kamringen (64) utgjøres dessuten av hydrauliske sylindre (66), som er montert for lott å kunne fjernes og skiftes ut, om nødvendig.A cartridge type coupling (10) comprises an outer body (16) having a plurality of cartridge segments (52), and a chamber (64) movably extending to the outer body (16) to move the cartridge segments (52) in a removable connection to a subsea wellhead (14). The canoeing (64) and the cartridge segments (52) have sets of cam surfaces. A first set (86, 92) cooperates for one to swing the cartridge segments (52) initially toward the wellhead (14), while a second set (96, 104) serves to further compress the cartridge segments (52) for the purpose of integrating the connector ( 10) fixed to the seabed wellhead (14). When the second cam surface set (96, 104) is in operation, the first set (86, 92) acts longer to swing the cartridge signal, so that the power requirement for A squeezes, "the cartridge segments (52) in clamping engagement is reduced to only one set if at a time, though both sets jointly contribute to A holding the cartridge segments in clamping engagement with the wellhead after definitive intervention is made. The coupling piece is further characterized by - firstly - that one set (86, 92) of cam surfaces serves to A keep the cartridge segments (52) conically oriented for A facilitating positioning of the coupling piece (10) over the wellhead (14), and - secondly - together with complementary stops (92, 94) A form a load path (arrow 122) between the cartridge segments (52) and the upper body (16), so that any load on the coupling piece (10) while being placed in the wellhead (14) ) will be transferred to the upper body. In addition, means for activating the cam ring (64) are comprised of hydraulic cylinders (66), which are mounted to be easily removed and replaced, if necessary.
