(Updates with estimated shipments on the mainline system in third paragraph.)

Dec. 20 (Bloomberg) -- Kinder Morgan Energy Partners LP said demand for January oil moved through its Trans Mountain pipeline system exceeds capacity by 63 percent, according to a bulletin to shippers.

Subscriptions on the portion of the system delivering to refineries in British Columbia and Washington were 69 percent over capacity, the Houston-based company said in the bulletin.

The Trans Mountain mainline system is expected to carry 260,700 barrels a day in January, 14 percent above estimated December shipments of 228,700, according a Nov. 23 notice.

The Puget Sound line will carry 133,000 barrels a day next month, the company said today.

The 715-mile (1,150-kilometer) Trans Mountain system runs from Edmonton, Alberta, to marketing terminals and refineries in central British Columbia, the Vancouver area and the Puget Sound region in Washington, according to the company’s website.

Products also move to California, the U.S. Gulf Coast and overseas through the Westridge marine terminal in Burnaby, British Columbia.

Nominations for “advanced timing” shipments to the Westridge dock were oversubscribed by 3 percent, according to the bulletin.
