Abstract

Anordning for å regulere fluidtrykket i et undersjøisk borehull (128), hvilken anordning er tilpasset for å brukes med et parti av et rør (110) plassert nedenfor slamlinjen, hvor anordningen omfatter en pumpe (53) som skal drive et fluid i røret (110), hvor nevnte fluid trykksettes av pumpen (53) for å regulere trykket i borehullet (128); og en utformingsinnretning (66, 94) for utforming av et borehull (128) nedenfor røret (110) mens trykket i borehullet (128) holdes under kontroll ved hjelp av nevnte pumpe (53). Det beskrives også fremgangsmåter ved bruk av anordningen.
