Abstract

En fremgangsmåte for oljeproduksjon fra et undervanns brønnhode (9) på sjøbunnen via et fleksibelt stigerør (4) til et dynamisk posisjonert fartøy (5). uten brtik av en svlvelkopling som forbinder stigerøret (4) med fartøyet (5) eller en kopling som krever at rør blir viklet ut og viklet opp. Innbefatter bruken av et fleksibelt stigerør. Lengden til det fleksible stigerør og posisjonen til fartøyet (6)1 forhold til brønnhodet (3) er slik at stigerøret (4) har et parti (A-B) inntil brønnhodet som bøyer under sin egen vekt. et parti (B- C) som forløi>er mer eller mindre horisontalt og er 1 stand til sideveis bevegelse, og et parti (C-D) inntil fartøyet (5). Istand til vertikal og sideveis beveg- else. Stlgererslengden er betydelig større enn vann- dybden 1 hvilke brønnen er plassert, for å skape rom for det horisontale parti av stigerøret og stlgerørs- konstruksjonen er slik at den har betydelig større tosjonsstlvhet enn bøyestlvhet. Fartøyet holdes på plass i>å en slik måte at det Ikke er stasjonert direkte over brønnen og slik at det geometriske sted til det nominelle senter for det dynamisk posisjonerte fartøysavtrykk kan beskrive en kurveiinjet bane som også er til siden for brønnens posisjon.
