Coastal GasLink completes compressor facility

Coastal GasLink said September 20 it had completed construction of the Wilde Lake compressor facility, the starting point for the 670-km pipeline that will deliver feed gas to the LNG Canada liquefaction terminal under construction on BC’s northern coast.

Wilde Lake comprises three compressor stations and four meter stations and represents the largest greenfield natural gas compressor station built by TC Energy – which owns 30% of CGL – in a single phase. It is designed to transport 2.1bn ft3/day of natural gas from Groundbirch, in northeastern BC, to Kitimat, site of the 14mn mt/yr LNG Canada facility.

If LNG Canada eventually sanctions a second 14mn mt/yr liquefaction phase, the capacity at Wilde Lake – and CGL – can be expanded to 5bn ft3/day to meet the added demand.

Wilde Lake incorporates industry-leading technology that reduces methane emissions by seven times compared to original estimates, CGL president Bevin Wirzba said.

“With Coastal GasLink, we are setting a new precedent for how we contribute to the clean energy transition – sustainably, safely and in partnership with indigenous and local communities,” he said. “This is sustainable energy the world needs more than ever, and with the completion of the Wilde Lake facility, we are one major step closer to collectively delivering it.”

More than 500 men and women worked on Wilde Lake over a two-year construction phase, generating a total of more than 1mn person-hours without a lost-time injury. The facility includes 24,000 diameter-inches of welds, 2,700 installed piles and nearly 120 km of cabling.

The entire CGL project, carrying an estimated cost of about C$11.2bn (US$8.4bn) is nearly 75% complete, and should be finished by the end of 2023.
