Ausenco designed a thermal pipeline to move bitumen emulsion from CNRL’s production facility at Primrose East to the Wolf Lake plant.
Thirty-two kilometres of 24-inch thermal above-ground pipeline was constructed in this $70 MM project to replace an existing underground pipeline.
The route is partially through challenging muskeg terrain. Due to seasonal access, the client required the completion of construction during one winter. To accommodate the schedule constraint, Ausenco modelled the entire pipeline route to position expansion loops, ensuring compatibility with existing pipelines, and incorporating road and wildlife crossings. The route selection minimised pipeline length, reduced environmental impact and maintained ease of access for construction and maintenance activities.
Ausenco designed piping bends with an extended tangent length to reduce the number of field welds at expansion loops by half. Innovative tie-in strategies and P&IDs eliminated the need for hot taps and the requirement for new pig launcher/receiver assemblies. The project was completed within budget and on schedule.
