Statoil shuts in production on Troll C platform off Norway

Statoil ASA said it temporarily shut in production on the Troll C platform in Troll natural gas field offshore Norway in the North Sea because corrosion was detected in an auxiliary gas treatment system.

Troll C handles 120,000 b/d of oil and 10.5 million cu m/day of gas, Statoil said. Troll C is a floating process and accommodation platform with a steel hull. Troll field lies in the northern part of the North Sea, about 65 km west of Kollsnes, near Bergen.

During a scheduled inspection, workers found corrosion on a tank in the glycol system, and production was stopped temporarily pending an investigation. Statoil said it is also checking a similar tank in a parallel gas treatment system. Meanwhile, a team of experts will determine what else needs to be done.

Statoil has 30.58% interest in Troll field, and Petoro AS has a 56% interest. AS Norske Shell has 8.1% interest, Total E&P Norge AS 3.7% interest, and ConocoPhilips Skandinavia AS 1.6% interest.
