The $4bn project will supply natural gas to Shell Energy’s proposed LNG Canada facility according to an agreement signed between Shell and TransCanada.
Construction on the pipeline project is expected to start in 2016 with operations scheduled to commence in 2018. The pipeline is estimated to have a life of up to 30 years.
Coastal GasLink Pipeline Project construction
The project will include the construction of a 670km-long, 48in-diameter pipeline to provide between two and three billion cubic feet a day (bcf/d) of natural gas that can be expanded to 5bcf/d through the addition of up to seven compressor stations, while a single compressor station will be built initially.
The project is planned to be built with top quality steel pipelines and welding techniques to maintain and protect against corrosion. All welds will be checked by an X-ray or ultrasound process during the construction.
The pipeline will be coated externally and cathodic protection measures will be utilised to maintain the integrity of the pipe and the coating.
Compressor and meter station details
The compressor station for the Coastal GasLink pipeline will be located in the Groundbirch area. It will include two 30MW natural gas-fired turbo-compressor packages.
Other auxiliary equipments to be installed at the compressor station include discharge gas coolers, high-pressure yard piping, isolation valves, electrical, control and telecommunication systems, storage facilities, and offices.
Three meter stations will be built near Groundbirch and Vanderhoof and at the pipeline’s termination point at the proposed LNG Canada facility. The meter stations construction is expected to be completed in five months.
Coastal GasLink Pipeline project timeline
The project was announced in June 2012, and began an engagement programme with aboriginal communities, local government, landowners and stakeholders.
Environmental and engineering studies were conducted along the pipeline corridor from between 2013 and 2014.
The British Columbia Environmental Assessment Office (EAO) issued an environmental assessment certificate for the project in October 2014.
Benefits of TransCanada’s natural gas pipeline
The project is expected to create between 2,000 and 2,500 jobs during construction and between 16 and 35 permanent jobs during operations.
It will also improve the local economy by employing local goods and services such as food, accommodation, hardware, fuel, parts and equipment.
