Decommissioning work taking place in Alberta and Saskatchewan
Along a 1,097-km corridor – stretching underground across the Prairies from Hardisty, Alta. to the U.S border at Gretna, Man. – is a new, 36-inch pipeline placed into service by Enbridge in October 2019. With the above-ground pipeline right-of-way returned to its pre-construction condition, work to decommission
the ‘legacy’ Line 3 continues in 2022.
“This is the final step toward completing the entire Line 3 Replacement Program in Canada,” said Construction Manager Allen Sawatzky. “We’re done in most of Manitoba and this year we’re focused on the remaining segments of Line 3 from Hardisty and throughout Saskatchewan to west of Cromer (Manitoba).”
The decommissioning project in 2022 will focus on three segments, beginning with the 255-km leg from Regina to Cromer in late spring, followed by Hardisty to Kerrobert (176 km) and Kerrobert to Regina (355 km) in late summer into fall. The general contractor for Hardisty to Kerrobert is Gee Bee Construction while the general contractor for Kerrobert to Cromer is Maxx North American Services Ltd.
Work in each segment will have a peak workforce of about 60, including crews of between seven and 10 construction and contract personnel. “Decommissioning is a logistically challenging job,” said Sawatzky. “It’s different than building a pipeline – you don’t just work from kilometre zero to kilometre 100 in a straight line. You go back-and-forth, from site-to-site, and the particular job in Manitoba in 2021 involved 31 different locations for segmentation, valve isolation and for installing engineered material in the pipe beneath railway and road crossings.”
There are 23 locations for segmentation, valve isolation and railway fill between Hardisty and Kerrobert, 34 locations between Kerrobert and Regina and 40 locations between Regina and Cromer.
