Coastal GasLink ends winter season with nearly 87% of construction complete

TC Energy-led Coastal GasLink has entered spring with nearly 87% of construction complete.

In an April update on its official website, it listed the following achievements:

• 85% of all water crossings completed
• Access to the Headwall, one of the project’s Steep Slopes in the Rocky Mountains, completed
• More than 567 km of pipe installed
• Nearly 94% of all pipe welded
• 44 million hours of work completed

More specifically, in regard to the project’s sections individually, Coastal GasLink noted that while pipe installation is complete on Section 1, work is ongoing to complete testing and advance final clean-up and reclamation efforts. It also pointed out that the construction on the Wilde Lake Compressor Station is ongoing.

Concerning section 2, the GasLink team said it completed pipe installation, backfill, and reclamation at watercourse crossings near KP 133 and KP 136, completed installation on Steep Slopes at KP 136, etc.

As for section 3, some of the achievements include the completion of the North Anzac Road extension and the continued installation of the Mt. Bracey valve site.

In sections 4 and 5, there are continued ESC mitigation and maintenance among other activities, while in section 6, the team completed mainline grading and stringing, completed hydro test of elbows at Parrott Lakes Future, and so on.

In section 7, Coastal GasLink said that all open-cut Fisheries and Oceans Canada (DFO) watercourse crossings have been completed and restoration is ongoing, adding that there are continued mechanical activities for MLBV 15 and 16, and so forth.

Finally, in regard to section 8, the team emphasised, among many activities, the installation of ESC mitigation measures along right-of-way, as well as the temporary reinstatement of isolated S6 watercourse crossings.

Coastal GasLink further informed that it is preparing for spring break-up, when field construction work is reduced due to soft, thawing ground conditions caused by melting snow, noting that during this time, the workforce is focused on critical and seasonally sensitive work, while also ensuring the integrity of site conditions and that enhanced erosion and sediment control measures are in place.

To note, once complete, Coastal GasLink will be Canada’s first direct link for LNG deliveries that will further support displacing 60 to 90 million tonnes of CO2 emissions annually.
