A worker has died and two others have fallen ill on a North Sea oil platform.
The man was airlifted to hospital from Marathon Oil's Brae Alpha, 155 miles north-east of Aberdeen, but later died on Thursday.
Another two employees were airlifted on Friday morning.
It is understood one had flu-like symptoms while the other had no significant problems.
A Marathon Oil spokesman said: "It is with deep regret that Marathon Oil UK confirms that a colleague has passed away.
"Our colleague was airlifted from the Brae Alpha platform and arrived at Aberdeen Royal Infirmary at approximately 11.15am.
"The evacuation was as a result of illness and not a work-related incident.
"Relatives of our colleague have been informed and all relevant authorities have been alerted."
The company said the incidents are not believed to be linked.
