Oil workers were left shaken yesterday when a warning light came on in their helicopter.
Ten passengers were travelling on the EC225 Super Puma when the alert went off on the last leg of their journey.
The aircraft had departed Aberdeen at 8.30am for the Fulmar Alpha North Sea platform landing at 11.20am.
The Talisman Energy-run installation sits almost 200 miles east of the city.
The Super Puma operated by Bristow Helicopters Ltd remained shutdown on the platform for the remainder of the day.
A Bristow spokes-woman said yesterday: “We can confirm that one of our Airbus EC225 helicopters is currently shutdown on an offshore installation.”
The precautionary temperature warning appeared on the helicopter’s cockpit display at around 9am.
The spokeswoman added: “This indication warning was not connected to the main gearbox. There were 10 passengers and two crew on board.
“The aircraft will remain offshore until an engineer has completed fault diagnosis and we are satisfied that the aircraft is serviceable to perform the return sector to Aberdeen.
“Flight safety is Bristow’s first priority and we will always investigate prior to further flight.”
Talisman Energy UK could not comment on the incident.
In 2012, 14 people on board a Bond-operated Super Puma of the same model survived after it ditched about 30 miles from Aberdeen on its way to the ConocoPhillips Jasmine field.
