A Greek tanker has been refloated off Psara on Tuesday.
The 2,400-dwt Eko 2 (built 2009) was said to have become stuck en route from Lesvos to supply the island's service station, the station's manager Angeliki Marinos told the Chios News website.
A tug went to the scene to help it refloat.
No injuries or pollution have been reported. The tanker has a crew of 17.
