The fishing vessel was fishing in a position 125 miles from Fraserburgh when the incident occurred.
Aberdeen Coastguard in the first instance secured medical advice for the crew by teleconnecting them with a duty doctor at Aberdeen Royal Infirmary. The decision was made that the man would have to be evacuated.
As there is a BP rescue helicopter based on the Miller Platform callsign Bond 1 Aberdeen coastguard requested their assistance.
Crew from Bond 1 and the rig standby vessel Grampian Courageous assisted in boarding the fishing vessel to administer pain relieving medication.
The Coastguard Helicopter R102 from Sumburgh was requested to fly out to the oil field where they winched the man into the helicopter and then refuelled on the Piper Bravo platform
He was then flown direct to Aberdeen Royal Infirmary where he is receiving treatment for his broken leg.
Matthew Mace, Aberdeen Coastguard said:
This was a long day for the skipper of the fishing vessel who had to endure a lot of different experiences to enable him to be eventually flown to hospital for treatment to his broken leg.
We are pleased that we were able to assist this man along with all the other people that were involved in his evacuation.
