Abstract

Et undervanns stigerørsystem frakobler bevegelser til et overflatefartøy (30) fra et stigerør (20) som strekker seg fra en havbunn (14). Et produksjonstre (12) er plassert på havbunnen. Et nedre stigerøranlegg (16) er koblet til produksjonstreet og et stigerør er koblet til det nedre stigerøranlegget med en nedre kobling (18). Stigerøret strekker seg oppover mot overflaten og er understøttet med oppdriftsmoduler (28) ved en øvre ende av stigerøret. Fartøyet på overflaten av vannet er koblet til en øvre ende av stigerøret med et fleksibelt øvre avsnitt (32). Ned-i-hullsverktøyer senkes fra fartøyet gjennom det øvre avsnittet, stigerøret og til brønnen.
