The Kristin field in the Norwegian Sea came back on stream on Jan. 22.
‘StatoilHydro has replaced lifeboat components and done extensive testing to ensure that these craft function in all weather and wave conditions. Kristin produces about 10 million cubic metres of gas and roughly 10,000 cubic metres of condensate per day. Production capacity is 20,000 cubic metres of condensate and just over 18 million cubic metres of rich gas per day. Production from Kristin has been shut down since 8 January. A number of specialist teams in the group have worked with the safety delegate service and lifeboat supplier Umoe Schat-Harding to find a solution. The authorities have been informed of the decision. “The problem with the new lifeboats on the Kristin platform was with the hydraulic mechanism which releases the lifeboats from the platform,” explained operations vice president Eileen Andersen Buan. Many of these craft have been modified, with new models installed on some installations during the past few years. The problems have fallen under three main heads: design weaknesses, the influence of gravitational forces during a drop, and driving the craft through the sea in extreme winds and waves.
