Lundin Britain Limited (a wholly owned subsidiary of Lundin Petroleum AB), confirms that all personnel have been returned to the platform following the incident on Sunday, 25 November.
Alan Curran, managing director of Lundin Britain Limited said, "An investigation into the cause of the incident is now underway. We are pleased that the safety systems and response processes worked well. We now are working to identify the cause of the incident. Thistle Alpha is an installation with a long and significant future and we have and continue to invest heavily in its refurbishment and upgrading. We also would like to thank all the organisations that supported the response."
Following the incident on Sunday 25 November 116 non essential personnel were down manned to the nearby Murchison and Dunlin platforms. 63 stayed on the Murchison platform overnight but returned to the installation earlier today. Production remains shut down.
Commenting on the incident John Methven, Petrofac Group HSSE Director (Petrofac is the dutyholder of the Thistle Alpha platform) said "We have to praise the Offshore Installation Manager and his crew on Thistle for carrying out a text book response to the incident. This and the support gained from the Coastguard, Royal Air Force (RAF), Bristow and other field operators demonstrated the levels of preparedness that exist in the industry."
