Production to restart at Chevron platform in North Sea after suspected gas leak causes shutdown

30 April 2018

Production was suspended on April 28 at a North Sea oil platform following a suspected gas leak. Chevron said the Alba Northern platform was shut at 17:50 as gas bubbles were spotted in the water. All 124 staff on the Alba Northern were safe and remained on the platform, the company said.

The Maritime and Coastguard Agency was informed after an alarm sounded on the platform, and the Health and Safety Executive confirmed that they had also been informed of the incident and were making initial inquiries.

On April 30, the company said there was no evidence of a gas leak from the platform or associated pipelines after a series of tests.

A spokeswoman said: "Chevron North Sea Limited (CNSL) is assessing the Alba Northern Platform following a precautionary shutdown of operations on Saturday 28 April 2018 when bubbles from an unknown source were detected on the sea surface near the platform.

"CNSL has assessed the subsea equipment and pressure tested the gas import line and found no evidence of a natural gas leak. The next stage is to initiate a controlled restart of production and continue monitoring to confirm our current findings under normal operations."

Alba Northern is situated around 130 miles north-east of Aberdeen.
