The Coastal GasLink pipeline project is approximately 670 kilometres (416 miles) in length and will safely deliver natural gas across northern B.C. to the LNG Canada facility in Kitimat, B.C., where it will be converted from gas to a liquified state (LNG) for export to global markets. The pipeline will be built to move 2.1 billion cubic feet per day (bcf/d) of natural gas, one of the world’s cleanest and most reliable energy sources, with the potential for delivery of up to 5 bcf/d.
LNG Canada selected TC Energy, a leader in the safe and reliable operation of North American energy infrastructure, to design, build and own the pipeline in 2012. The Coastal GasLink pipeline route received approval from the Environmental Assessment Office in May 2018 after rigorous assessments considering Indigenous, landowner and stakeholder input, the environment, archaeological and cultural values, land use compatibility, safety, constructability and economics. Construction activity began in January 2019 and is estimated to be completed in 2023.
Coastal GasLink traverses some of the most challenging terrain in Western Canada. TC Energy chose PipePillo® engineered pipeline supports to support the pipeline from the rocky trench bottom, allowing sand padding to encompass the pipeline while maintaining an easy path for cathodic protection. PipePillo® are environmentally inert and offer 90° of permanent pipeline support, an important consideration in this challenging and environmentally sensitive terrain. To date, over 7700 PipePillo® structured pipeline pillows (SPP48) have been installed.
