Narrative:

While level at FL330 in vicinity of 54N 44W on north atlantic track proceeding eastbound, we experienced loss of oil pressure and had to shut down #3 engine. Declaring an emergency with gander we turned and descended off track to north, and once clear, turned and received at that time clearance to return to st. Anthony. We eventually, considering nature of emergency, remaining fuel, WX, etc, returned to boston (our original departure station) without incident.
