UPI provided routing studies, FEED, detailed engineering, field investigation, and owner’s engineering services for a 48 km NPS 24 pipeline from the north end of the Coquitlam Watershed in the Greater Vancouver Regional District (Metro Vancouver) through mountainous terrain to an LNG export facility at Woodfibre, southwest of Squamish, British Columbia.
The new NPS 24 pipeline runs generally parallel (i.e., loop) to the existing NPS 10 pipeline that is part of the natural gas transmission system that services Squamish, Whistler, the Sunshine Coast, and Vancouver Island. The loop was created to operate in parallel with the existing pipeline to increase the overall natural gas transmission capacity of the Company transmission system in order to meet the requirements of the facility. The offshore scope of work included studying a proposed crossing of the Howe Sound, including approximately 3.6 km of NPS 24 subsea pipeline.
