Abstract

En dypvanns-stigerørsammenstilling innbefatter en nedre BOP- (boresikringsventil) stabel (34) plassert tilstøtende og forankret til bunnen (20) av sjøen og en øvre BOP-stabel (40) festet til stigerøret ved et vannivå tilstrekkelig dypt under overflaten for å være upåvirket av overflatestrømmer. Den øvre BOP-stabelen (40) har skjæravstengerne over rørsavstengerne for å adskille seksjonen av borerøret over skjæravstengerne for å tillate at den øvre seksjonen av borerøret mellom skjæravstengerne og boreskipet kan gjenvinnes etterfulgt av seksjonen (43) til stigerøret over den øvre BOP-stabelen for å frigjøre boreskipet, slik at det kan bevege seg etter behov for å bedre ri av en overflatestorm. En flytemodul (38) er festet til stigerøret under den øvre BOP-stabelen (40) og utøver en oppoverrettet kraft som holder stigerøret under den øvre BOP-stabel (40) frittstående og i strekk. Midler er fremskaffet for å gjenforbinde den øvre seksjonen av stigerøret til den øvre BOP-stabelen etter at stormen har passert.
