A North Sea oil platform has been shut down after a potentially-deadly gas was detected on board.

Chevron's Alba Northern platform was shut down as a 'precautionary measure' earlier today after an alarm went off during routine well operations in the vicinity of drilling activity.

A spokesperson for the company told Energy Voice: "As per routine procedures, the well was secured and all 139 personnel on board were called to muster and safely accounted for.

“The platform returned to full operations following muster”.

The shut down comes days after 80 people were evacuated from the storm-damaged Brent Bravo North Sea oil platform.

Crews were airlifted off Brent Bravo on Sunday evening after damage was discovered on one of the legs of the platform.

Shell confirmed that the evacuated personnel had been taken to Brent Charlie as a precaution.
