Greek owner Stamatis Molaris’ Empire Navigation is investigating whether Iranian oil was transferred on to one of its managed tankers.

US pressure group United Against Nuclear Iran (UANI) first brought the allegation involving the 159,000-dwt Suez Rajan (built 2011) to light in February.

Empire Navigation said it was “aware of the allegation of non-compliance regarding our managed vessel, Suez Rajan, related to a ship-to-ship transfer of Iranian oil”.
