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.An underwater riser system disconnects movements of a surface vessel (30) from a riser (20) extending from a seabed (14). A production tree (12) is located on the seabed. A lower riser system (16) is connected to the production tree and a riser is connected to the lower riser system with a lower connection (18). The riser extends upwards towards the surface and is supported by buoyancy modules (28) at an upper end of the riser. The vessel on the surface of the water is connected to an upper end of the riser with a flexible upper section (32). Downhole tools are lowered from the vessel through the upper section, riser and into the well.
