For shits & Giggles let us look. Scenario #1
If a transporter were to leave from ST. Johns and by way of Panama canal to the port of Zhenjiang, China
Miles = 11,433Scenario #2
If a transporter were to leave from ST. Johns and by way of Horn of Africa to the port of Zhenjiang, China
Miles = 13,960http://www.searates.com/reference/portdistance/
Now take Fort McMurray. heart of Tar sand oil. Pipeline transport by put on hold project, Northern Gateway. A trip = to 731 miles.
And the proposed reverse flow & added extension pipeline project, by TransCanada. A route from Ft. McMurray to St. John = 2734 miles. This is already starting to build up resistance! To be seen if they will prevail. Plus the current St. Johns refinery only has a capacity of 298,800 barrels a day.
So yes, a bit longer, But would like to see the financial differences?
