CNR International seals North Sea well after leak fears

27 May 2014

Canadian energy group CNR International said on May 27 it is in the process of sealing a well on board the Ninian Central platform and the process was expected to be complete within 96 hours. A spokeswoman for the company stressed that no oil had been released into the sea and that the event was not an emergency situation.

She added: “CNR International can confirm that as a result of issues identified during planned well integrity testing on the Ninan Central platform, intervention work is being undertaken to plug a well.

“The primary pressure containment barrier of the well is intact, but well integrity testing identified that the outer casing strings have been compromised.

As a precaution, non-essential workers continued to be flown off the platform, located in the northern North Sea, around 100 miles east of Shetland. The company has now reduced the number of workers from 172 to 79.

The Health and Safety Executive and the Department of Energy and Climate Change have been informed.

The incident happened just weeks after the CNR-operated Tiffany platform – which was under a health and safety investigation at the time – was shut down following two small fires which revealed health and safety problems on the rig.

In 2010 the Health and Safety Executive ordered the firm to make improvements on the platform following a "significant" gas leak.
