Shell has said the flow of oil from a leaking pipeline has stopped after divers closed a relief valve on Friday. The pipeline on its Gannet Alpha platform off the coast of Aberdeen had been leaking for over a week.
The company said divers had managed to shut off the leaking relief valve on Friday and no oil had been released since then. Shell said it will continue to monitor the line.
Scottish environment secretary Richard Lochhead said: “The situation will need to be closely monitored … to ensure this has been successful.”
Some 36 concrete mats were laid on the flowline in a process to secure it to the seabed, as the line had been depressurised and there was a problem with buoyancy.
Shell has set up an investigation team to establish the cause of the leak.
