Abstract

Det er beskrevet et marine boringssystem og en fremgangsmåte ved bruk av en oppover-strekkende foringsrørstreng (27) for å forbinde et brønnhode for boreslamledning (26) og et flytende brønnhode (28). Begge brønnhodene er i stand til å bære vekten av etterfølgende installerte foringsrørstrenger. En ut- blåsningssikring (24) er forbundet til det flytende brønnhodet. Den forlengede delen av foringsrørstrengen holdes under strekk ved hjelp av en styrt flytemodul (29). Et forenklet og forkortet vanlig stigerør forbinder utblåsningssikringen til en flytende rigg. For å stabilisere systemet, kan riggen (22) være forbundet til stige- røret (23) og foringsrørforlengelsen ved hjelp av en serie vinklede stag (281). Systemet er særlig nyttig for dypvannsboring ettersom det reduserer lengden av stigerøret betraktelig.
