The Canada-Newfoundland and Labrador Offshore Petroleum Board (C-NLOPB) was notified on Friday, November 19th by officials at Husky Energy that the company was managing elevated levels of H2S (Sour Gas) in two of the storage tanks on board the SeaRose FPSO.
H2S levels were elevated in the tanks due to an inoperable circulating pump. As a precautionary measure, all non operating activities were shutdown and personnel returned to accommodations. Access to operating areas was restricted. Part of the process to manage the H2S levels involves venting.
Thirty-three workers whose duties require them to work on the deck, have been transported off the SeaRose due to a lack of work activity. Fifty-three personnel remain on board.
The C-NLOPB is satisfied that Husky has taken prudent proactive precautions to manage the H2S levels. The C-NLOPB is continuing to monitor the situation and will be doing further follow-up with Husky Energy.
