Greenpeace spokesman Mike Hudema says the activists unchained themselves from various pieces of equipment at Kinder Morgan's Westridge facility Wednesday night and were briefly detained by police before being released.
Protesters occupied the site early Wednesday, vowing to send a strong message to Prime Minister Stephen Harper urging him to halt plans for oil pipeline expansion in British Columbia.
Kinder Morgan says no ships were due to be loaded at the Burrard Inlet facility just east of Vancouver, so operations were unaffected.
The Westridge plant is the terminus for Kinder Morgan's Trans Mountain pipeline, which carries petroleum products from Alberta to the West Coast for shipment overseas.
Kinder Morgan has applied to nearly triple the daily capacity of the pipeline from 300,000 barrels to 890,000 barrels. (CKNW)
