Dawson Phase III Gas Plant Construction
The Dawson Montney play is the foundation of ARC's low-cost natural gas business. The Dawson Phase III facility is designed for processing capacity of 90 MMcf per day and 7,500 barrels per day of liquids-handling capacity (approximately 50 per cent condensate-handling). The new facility started up in mid-June, ahead of schedule, and with an exceptional safety record through construction and start-up. The smooth commissioning of this facility was the result of strong performance by our experienced field operation and commissioning teams.

ARC received the leave to open from the BC Oil and Gas Commission in early June. At the end of Q2 2017, construction of all major trunk lines as well as sales lines to third party midstream companies was completed. The first multi-well pad was drilled and completed on schedule to provide the plant with initial gas volumes.
Physical construction of the Dawson Phase III gas processing and liquids-handling facility continues with the majority of mechanical work now complete. Over 80 kilometers of pipelines were installed in the first quarter of 2017, including the gas gathering systems for the facility and the sales lines that will allow for dual-connectivity to third-party pipeline infrastructure. Construction of the facility continues as ARC prepares for upcoming commissioning activities.
Plant construction activities continue as crews work towards completion of all mechanical activities. Installation of piping in and around the turbine generator building and the refridge buildings is underway. Electrical crews continue to pull cable, set trays and complete grounding work. Pipeline construction is progressing smoothly.
Construction activities continue on schedule, with all major equipment now on site. Mechanical construction work is ongoing, and electrical cable and tray installation is underway along with wiring of the turbine buildings. Operational environmental approvals have been submitted for review.
Plant construction is moving along smoothly despite the cold weather at Dawson. Equipment continues to arrive on site with pipe rack fabrication and installation now complete. Shop fabricated piping is being placed in the rack and the inlet/outlet pipeline risers installed at the inlet header. The waste heat recovery system for the power turbine generators is being assembled. Installation and certification of the safety line is underway and the electrical contract for the plant has been awarded.
Major equipment is on schedule and in the process of being delivered on-site. Pipeline construction has commenced to tie-in initial multi-well pads. Drilling has commenced on the first of two multi-well pads to fill the plant in 2017.
Following the completion of earthwork and leveling of the site in late 2015, piling work was recently completed to create foundation support for buildings and equipment. Piperacks and process equipment are currently arriving on site.
