Damia Desgagnes is the first dual fuel bitumen/asphalt tanker in the world and is the first of four to be built for the Desgagnes fleet. Asphalt tankers have higher energy use than conventional tankers, since they must keep the cargo hot, and therefore are generally bigger air pollution contributors than other types of ships.
Delivered earlier this year by Besiktas Tersane AS, in Yalova, Turkey, the ship has been operating on the St.Lawrence River and Great Lakes since May. It is also a Polar Class 7 vessel, so will be trading all winter as well. The ship measures 11,978 gross tons, 15,100 dwt.
In case I don't get out to take a picture in Halifax, the above were taken during the annual Shipfax summer break in Quebec.
