A Canadian law barring oil tankers from the northern coast of British Columbia hasn’t stopped crude from setting sail there.

Two Calgary-based companies, Melius Energy and BitCrude, are exploiting a loophole in the law passed this summer -- by shipping semi-solid bitumen mined from oil sands on a cargo ship rather than in liquid form on an oil tanker. About 130 barrels of bitumen left Prince Rupert, B.C., on Saturday bound for a refinery in China, according to Cal Broder, founder of both companies and chairman of BFH Corp. He declined to name the cargo’s buyer.

“What this demonstration was for was to show we can meet all regulatory requirements” for shipping out of Prince Rupert, Broder said by phone Wednesday.

Canada’s Senate in June passed Bill C-48, banning oil tankers off the northern B.C. coast, against the objections of the oil sands-producing province of Alberta. Broder was able to get around the ban by sending the bitumen in a 20-foot shipping container in a semi-solid state, undiluted with lighter oils such as condensate.

Sonya Savage, Alberta’s energy minister, welcomed the news of the shipment.

“I’ve been following Bitcrude for awhile and am pleased to see exports off the NW coast of B.C.!” she said in a tweet.

This is great news!



Alberta bitumen is now en route to International markets after leaving the Port of Prince Rupert this week by shipping container. I’ve been following Bitcrude for awhile and am pleased to see exports off the NW coast of B.C !

The concept of sending bitumen in solid form in shipping containers isn’t new. Companies have been developing technologies to send oil in the form of bricks or pellets for several years. The technology could help Canadian oil producers overcome a pipeline shortage that’s caused local oil prices to collapse last year and prompted the Alberta government to impose production limits on large producers.

The bitumen shipped to China came from an oil sands producer that Broder didn’t identify. After diluent was removed, it was loaded onto a rail car and sent to Prince Rupert. Broder said he is currently setting up a processing center near Edmonton and plans to start shipping his undiluted bitumen on a commercial basis to China as early as this year.
