Royal Dutch Shell PLC Friday confirmed that an oil spill has occurred at its Gannet Alpha platform in the U.K. North Sea.
"We can confirm we are managing an oil leak in a flow line that serves the Shell-operated Gannet Alpha platform," said Shell spokesman Kim Blomley.
"We have stemmed the leak significantly and we are taking further measures to isolate it," he said. "The subsea well has been shut in, and the flow line is being depressurized. We continue to monitor the situation on the surface and subsea."
Blomley said Shell has informed the relevant U.K. authorities.
The Maritime and Coastguard Agency said: "We are aware of the incident, our counter-pollution and salvage officer is monitoring the situation." The Health and Safety Executive said it was making enquiries into the incident.
The platform is located 180 kilometers east of Aberdeen. Shell operates the platform along with partner ExxonMobil Corp.'s U.K. unit Esso.
