Nov. 21 (Bloomberg) -- Enbridge Inc. apportioned December shipments on five pipelines that ship crude oil from Alberta to the U.S. Midwest and eastern Canada after space was overbooked.
Lines 2a and 3, which can transport a combined 832,000 barrels a day of light oil from Edmonton to Superior, Wisconsin, were apportioned by 6 percent, Graham White, a spokesman for the Calgary-based company, said in an e-mailed statement.
Line 4, which can carry as many as 796,000 barrels a day of both light and heavy crudes along the same route, was apportioned by 10 percent, White said.
Line 14 from Superior to refineries near Chicago was apportioned by 11 percent, and Line 6b from the Chicago area to Sarnia, Ontario, by 45 percent, White said.
The lines are all part of the company’s Mainline, the largest crude-oil export system from Canada to the U.S., with as much as 2.5 million barrels a day in capacity.
Apportionment occurs when shippers ask to transport more oil than a line can hold and typically indicates excess demand or lower capacity. A 45 percent apportionment means shippers will only be able to deliver 55 percent of the volumes they sought to transport.
