Used to be there was not enough refinery capacity on the west coast for Alaska oil but as the oil exported has declined ( some storage tanks shut down a Valdez already) I'm not sure that is a problem now.

You cannot travel that additional distance for less cost regardless of who crews or built the ship.
Alaskan crude was also tranported to Texas via tanker, trans Panama pipeline and tanker.
