Over 55% of Canadian Oil Exports From Trans Mountain Have Diverted Through California to Save Money

Canada’s newest oil pipeline has turbo-charged exports of the country’s heavy crude to Asia and a diversion through California is making for a longer but potentially cheaper journey.

Close to 3 million barrels have been shipped off Vancouver for China or India since the expanded Trans Mountain pipeline began operating in May, almost tripling the capacity of the sole system linking Alberta to a Canadian port. More than 55 per cent of those volumes have first journeyed south to Southern California where the crude was transfered onto very large crude carriers, or VLCCs, according to Vortexa ship tracking data.

The transfers have offset one of the key disadvantages of exporting Canadian crude off the West Coast versus the U.S. Gulf: the port of Vancouver can only accommodate Aframax-size tankers or smaller, which hold less than half of what VLCCs hold. As such, shipping directly from Western Canada to distant markets would typically cost close to twice as much per barrel per day than on VLCCs, according to a ship broker familiar with rates who asked for anonymity because he is not authorized to discuss the information. However, the diversion to California has lengthened the time of the journey to Asia, reducing a key advantage of exporting Canadian crude off the West Coast versus the U.S. Gulf.

The practice is expected to become more common as Aframax tankers are redeployed for making shorter voyages, the broker said. Other’s aren’t as sure.
