No Alaskan crude oil has been exported outside of the United States since 2004. Genscape Vesseltracker monitoring data showed that a cargo of Alaskan North Slope crude was loaded Sept. 26 at the Alaskan port of Valdez for delivery into the South Korean refining center of Yeosu, says a Genscape blog post. The U.S.-flagged tanker, Polar Discovery, is reported to have sailed from the ANS export terminal at Valdez, Alaska, for east Asia. Yeosu is home to a GS Caltex-operated 775,000 bpd refinery, the world’s fourth largest. The Polar Discovery is expected to arrive at Yeosu on October 10, according to Vesseltracker. According to the U.S. Energy Information Administration, no Alaskan crude oil has been exported outside of the United States since 2004.
