Enbridge鈥檚 Line 3 Replacement is complete and will ship its first oil on Dec. 1.
In Canada, that is.
The Minnesota portion 鈥� the replacement portion 鈥� has not been built, due to continual delays in that state. But that does not mean that Line 3 is not in operation, nor is the Canadian Line 3 replacement a pipeline to nowhere. The new pipe meets the old pipe at the international border at Gretna, Man. And the old pipe, in the U.S., continues to be in usage until it is replaced.
As a result, the new pipeline, one of five pipes that makes up Enbridge鈥檚 Mainline system, will soon be in operation.
鈥淲e鈥檙e going into commercial service Dec. 1,鈥� said Enbridge spokesperson David Coll.
The mainline system runs from Hardisty, Alta., east-southeast through southern Saskatchewan and Manitoba. It crosses into North Dakota at its very northeast corner before going on through Minnesota to Superior, Wisc. From there the mainline system splits, going through Wisconsin and Michigan to Sarnia, Ont., and south to Chicago, around Lake Michigan, and again to Sarnia.
A sixth pipeline in the Mainline, Line 13, was reversed and is used to import diluent into Canada. It is now known as 小蓝视频ern Lights. While there are other export pipelines, the Enbridge mainline system is the primary conduit of Canadian oil exports from Canada to the United States.
As the old Line 3 in the United States is operating at a reduced capacity, the new line in Canada is, for now, going to run at about half its rated capacity.
鈥淓nbridge had previously indicated 50,000 to 100,000 barrels per day of additional throughput on the Mainline in 2019 through various optimizations,鈥� said Coll. 鈥淗aving the Canadian portion of the Line 3 Replacement Program (L3RP) in-service provides additional flexibility in terms of how we meet our 2019 throughput objective. The new Line 3 won鈥檛 have the same operating restrictions of the old line in Canada.
鈥淏ringing it into service allows us the flexibility to transport more product in Canada and it allows us to maximize previously under-utilized points on the system, which can then be connected to existing Mainline pipes in the U.S. that are able to take on the capacity while still meeting all regulatory requirements, including all maximum allowable operating pressures.
鈥淭he L3RP is an essential, reliability and safety-driven maintenance project constructed with the newest and most advanced pipeline technology. We are putting this into service because it鈥檚 brand new infrastructure that鈥檚 ready to go. We will continue to operate Line 3 in Minnesota within the lower maximum allowable operating pressure limits set several years ago to ensure safe and reliable operations.鈥�
The new pipeline will run at approximately half of its rated capacity, some 400,000 barrels per day, until such time as the Minnesota portion receives final approval, is constructed and brought on stream.
鈥淔irst and foremost, the Line 3 project was about enhancing the safety and integrity of infrastructure that is critical to the functioning of our society, much like a highway, a bridge, or an airport,鈥� Leo Golden, vice-president, Line 3 project execution, said in an emailed statement. 鈥淭oday, Line 3 is one of more than 80 oil and gas pipelines and 30 major electric transmission lines that cross the Canada-U.S. border, operating as part of a single, integrated North American energy market. Access to this continental energy market is critical for consumers, industry and governments.鈥�
The new pipeline stretches approximately 1,070 kilometres (665 miles) from Hardisty, Alberta to Gretna, Manitoba. At an estimated cost of $5.3 billion, it represents the largest capital expenditure 鈥� which Enbridge noted is the largest and most successful stakeholder engagement undertaking 鈥� in Enbridge鈥檚 70-year history in western Canada.
While most of the topsoil has been put in place, there is a portion that did not wrap up this year. Around 100 kilometres of right-of-way remains, in the proximity of the Langbank pumping station and south of Moosomin.
The company has three years to decommission the old Line 3 in Canada, which will involve draining it, segmenting it and permanently sealing it off. The line will be left in the ground, as removing it would be as significant an operation as installing a new pipe, but with the added difficulty of working between several pipes in operation.
