The Shetland coastguard helicopter has been used to carry out emergency medical evacuations for two workers from separate North Sea platforms.
The alarm was raised at 7.50am on Sunday when a man was taken off an installation 73 miles from Sumburgh.
He was taken to Lerwick’s Gillbert Bain Hospital but his condition remains unknown.
A short time later the aircraft was dispatched to another rig 130 miles east of Shetland to transport a worker who had fallen sick to Bergen.
The helicopter returned to base at around 2.30pm.
