Aug 21, 2011
An update from Shell U.K Limited on the Gannet Alpha oil leak
On Friday, Shell divers closed the relief valve from which oil had been seeping.
No oil has been released since that point. Continuous monitoring is being carried out to ensure the closure of the valve has been fully successful. That monitoring will continue.
The Maritime and Coastguard Agency surveillance flight on Saturday found no oil on the surface.
36 concrete mats have been successfully laid on the flowline in a process to secure it to the seabed. This process will continue over the next few days.
