Leak Detected at Asgard B Platform

The leak was discovered in the morning and production from the platform was consequently stopped until the same afternoon.

Svein Fredriksen, technical operations manager on Asgard B, reports that the platform has now resumed normal production and is exporting roughly 26 million cubic meters of gas per day. According to Mr. Fredriksen, the leak originated in closed valves on the water outlet from the Smorbukk oil separator. The crude got into the flash tank for produced water and then leaked into the sea along with the water The crude will gradually be broken down and will not reach the shore, but the film of oil on the sea is being monitored. The Norwegian Pollution Control Authority (SFT) has been notified in accordance with normal procedure.
