A crewman on board a 300-metre bulk carrier ship was medically evacuated off Port Lincoln last week after suffering a broken arm 470-kilometres out at sea.
The crewman was on board the MV Ludolf Oldendorff that had departed Whyalla and was on its way to China when the call for assistance was made about 470-kilometres west south west of Port Lincoln.
An Australian Maritime Safety Authority (AMSA) spokesperson said the master of the vessel reported the injury and in consultation with the Tele-medical advice service doctor a MEDEVAC was recommended.
They said the ship turned around and traveled about 380-kilometres closer to the coast to meet rescuers.
"AMSA tasked the South Australian Ambulance helicopter, Rescue 51 to conduct the MEDEVAC, and the AMSA Challenger search and rescue jet from Essendon as top cover," they said.
"Just after first light on Wednesday 8 May, the injured crew member was winched from the vessel about 130-kilometres west of Port Lincoln and transferred to Royal Adelaide Hospital for treatment."
The spokesperson said the bulk carrier ship had continued on its voyage as planned.
