Fiver fishermen were rescued by the Coastguard after fleeing their burning vessel.
The crew are being treated with hypothermia after the dramatic rescue.
At 13.28 pmtoday a distress alert was received by the Coastguard from an emergency radio signal.
It was quickly identified as belonging to a fishing vessel registered in Buckie called Onward.
The fishing vessel was in a position, 50 milesnorth west of Stromness.
Shetland Coastguard made a mayday relay broadcast to secure assistance from any other vessels in the area.
A merchant vessel Nautica responded and diverted to the last known position.
A Maritime surveillance aircraft, Watch dog 65, was tasked to attend and report back.
A rescue helicopter was requested from ARCC Kinloss and the Coastguard rescue helicopter R102 based at Sumburgh was sent.
Stromness RNLI lifeboat was also requested to launch, but has been stood down and the Nautica is continuing it’s passage.
Rescue 102 arrived on scene and found the fishing vessel had been on fire and that the crew had evacuated to liferafts.
They were winched into the helicopter, and now all five crew have been evacuated to the hospital at Kirkwall suffering from hypothermia.
