No heavy grade oils onboard Portuguese single hull tankers

In a recent communication to IMO MEPC Circ. 476, the Portuguese Maritime Administration advises that it will refrain from granting extensions under the new Regulation 13H of Annex I of the MARPOL Convention. In other words, no heavy grade oils (HGOs) are permitted onboard Portuguese single hull tankers, irrespective of whether they have double sides or double bottoms.  

Although not mentioned in this notification to IMO, Portugalwill allow transportation of HGOs to and from its ports onboard double hull tankers.
