Shell has evacuated nearly 80 workers from its Brent Bravo platform in North Sea due to fears of damage from Storm Imogen.

The storm is believed to have caused structural damage to one of the platform’s legs.

A clamp came loose from one of the legs of Brent Bravo platform and remained hanging above a gas pipeline, which is linked to the St Fergus terminal.

As a precautionary measure, the company moved 40 people to the Brent Charlie and remaining to the nearby Brent Delta and notified relevant authorities about the incident.

"A clamp came loose from one of the legs of Brent Bravo platform."

Brent Bravo platform is located about 115 miles north-east of Lerwick.

Production at Brent oil and gas field commenced in 1976.

The field is located in the East Shetland Basin of the North Sea, 186km north-east of Lerwick, Shetland Islands, Scotland, at water depths of 140m.

The incident follows a separate storm that left scaffolding dangling from the company’s Brent Delta platform last month.
