A handful of people have been flown off a North Sea platform after cases of Covid-19 were found on board.
Apache confirmed that four crew members have left its Forties Delta installation after testing positive for the virus.
The Houston-headquartered oil and gas company said the individuals were flown home using a “specialist helicopter service”.
Work is now ongoing with the relevant healthcare bodies to ensure the crew members are “properly cared for”, Apache said.
Forties Delta is located about 140 miles north-east of Aberdeen,
In a statement, Apache said: “Apache North Sea can confirm that four crew members have left Forties Delta installation after testing positive for Covid.
“The individuals were transported by a specialist helicopter service and we are working with Health Protection Scotland and our healthcare partners to further assess the individuals and ensure they are properly cared for.
“All necessary steps are being taken to protect the health and safety of our people working offshore.”
Repsol Sinopec Resources UK confirmed in July that it had reduced the crew on Piper Bravo to “essential workers only” due to Covid.
In the last few months there have been similar outbreaks on the Shell Shearwater and Taqa North Cormorant platforms.
Meanwhile, Shell’s Champion 7 offshore oilfield cluster in Brunei has also been hit hard by the virus in recent weeks.
The outbreak on Forties Delta coincides with a surge in Covid cases in Scotland, with vaccine passports likely to be introduced in the near future.
