More than 70 workers were taken off a North Sea oil platform after a leak was detected.
The Cormorant Alpha platform and its pipeline infrastructure were also shut down as a precaution.
Seventy-one of the 145 staff members on board were removed from the rig, operator TAQA Bratani said.
The leak, discovered in one of the rig’s legs during maintenance work on Saturday, has now been contained, a company spokesman confirmed.
All members of staff are said to be safe and well.
