Production has restarted at BG Group operated Knarr field in the North Sea, offshore Norway, after a fire halted output last week.
The fire broke out on the Petrojarl Knarr FPSO on 24 March, just a week after BG brought the field online, on 18 March.
BG Group has said that the fire broke out in a heating, ventilation and air-conditioning unit in a technical room on the vessel’s foredeck.
Investigating the fire, Norway’s Petroleum Safety Authority (PSA) said it lasted around forty-five minutes. The one hundred staff on board at the time gathered at the lifeboats.
The Petrojarl Knarr is moored around 120km off the Norwegian coast. It is regarded as one of the world’s largest harsh-environment FPSOs, with production capacity of 63,000 boe/d and storage capacity of 800,000 bbl. BG is leasing the vessel, which was built in 2014, from the Teekay Corporation.
The Knarr field is around 50km north of the Snorre field, in the Tampen area of the Norwegian North Sea. It has estimated recoverable reserves of approximately 80 MMboe at a water depth of around 400m. A Brewin Dolphin drilling rig discovered the field in July 2008 and the Norwegian Government approved the project in 2011. BG operates the field with production and injection subsea templates.
BG has a 45% working interest in the field. Its partners in the project are Idemitsu Petroleum Norge (25%), Wintershall Norge (20%) and DEA Norge AS (10%). Additional exploration drilling in the licence area is ongoing.
