If all goes to plan, oil tankers carrying Canadian and North Dakota crude oil could be shipping out of the Port of Duluth next year. Business North, WDIO and others have the story. Decades ago, oil had previously been shipped out of Duluth. Tankers run in other parts of the Great Lakes. This particular project would only amount to about two ships a year and 15 new employees, but that could grow if the endeavor works.
