Abstract

Fremgangsmåte for boring i bunnen av et hav fra en flytende konstruksjon ved bruk av et roterbart rør innbefatter et tetningshus (20) som har en roterbar tetning tilkoplet ovenfor et parti av et marint stigerør (R) fastgjort i havets bunn. Tetningen som roterer sammen med det roterende rør, tillater stigerøret (R) og tetningshuset (20) å opprettholde et forhåndsbestemt trykk i systemet, hvilket er ønskelig ved boring med trykksatt slamplugg og reversert sirkulasjon. En fleksibel ledning eller slange blir brukt for å kompensere for innbyrdes bevegelse mellom tetningshuset (20) og den flytende konstruksjon fordi den flytende konstruksjon beveger seg uavhengig av tetningshuset (20). Borevæsken blir pumpet fra den flytende konstruksjon og inn i et ringrom i stigerøret (R) og tillater utformin g av en slamplugg (1330) nede i hullet i stigerøret (R), eller tillater reversert sirkulering av borevæsken ned gjennom stigerøret (R) med tilbakestrømning opp gjennom det roterbare rør til den flytende konstruksjon.
