Trans Mountain Pipeline System

In operation since 1953, the Trans Mountain pipeline system (TMPL) is the only pipeline system in North America that transports both crude oil and refined products to the west coast. TMPL moves product from Edmonton, Alberta, to marketing terminals and refineries in the central British Columbia region, the Greater Vancouver area and the Puget Sound area in Washington state, as well as to other markets such as California, the U.S. Gulf Coast and overseas through the Westridge marine terminal located in Burnaby, British Columbia. Only crude oil and condensates are shipped into the United States.

Edmonton South Terminal

The TMPL mainline originates at the Edmonton South terminal, located in Sherwood Park, Alberta. The terminal has 20 incoming feeder lines from throughout Alberta. With the recent completion of the Edmonton Terminal Expansion Project, the site contains 35 tanks and has a capacity of approximately 8 million barrels (1.27 million m³). The main Control Centre located at the terminal remotely monitors all aspects of the Trans Mountain pipeline and terminal operations with the sophisticated Supervisory Control and Data Acquisition (SCADA).

Kamloops Terminal

Refined products from Edmonton are routed to Kamloops for local distribution. Kamloops is also a receiving site for products from northeastern British Columbia that are bound for the west coast. The facility contains two storage tanks with a shell capacity of 160,000 barrels (25,000 m³).

Sumas Pump Station and Terminal

The Sumas pump station and the Sumas terminal are located in Abbotsford, British Columbia. Both facilities route crude oil from the TMPL mainline into Washington State via KMC’s Puget Sound pipeline system. The terminal contains six storage tanks and can handle volumes of approximately 715,000 barrels (114,000 m³).

Burnaby Terminal

The Burnaby terminal is the terminus of the TMPL mainline. It receives both crude oil and refined products for temporary storage and distribution through separate pipelines to local terminals, a refinery and the Westridge marine terminal. The Burnaby terminal has 13 storage tanks and can handle volumes of approximately 1.685 million barrels (268,000 m³).

Westridge Marine Terminal

In service since 1956, the Westridge marine terminal is located within Port Metro Vancouver in Vancouver, British Columbia. Regulated by Transport Canada and the National Energy Board, it can accommodate ships up to Aframax in size (approximately 120,000 dead weight tons) and barges. In addition to shipping crude oil, the facility also receives and ships jet fuel, which is delivered to the Vancouver International Airport through the Jet Fuel pipeline system. The Westridge marine terminal houses three storage tanks and can handle volumes of approximately 395,000 barrels (63,000 m³).

Products in the Pipeline

TMPL transports crude oil, refined and semi-refined products together in the same line. This process, known as “batching,” means that a series of products can follow one another through the pipeline in a “batch train.”

A typical batch train in the mainline is made up of a variety of materials being transported for different shippers. Products next to each other in the pipeline can mix. This mixing - or product interface - is kept to a minimum by putting the products in a specific sequence. Any products that do mix are re-refined for use.
