Abstract

The NEBC Connector consists of two parallel pipelines (NPS 8 - NPS 12) and is approximately 213km in length. Of the approximately 213km, 190km will be in British Columbia and the remaining 23 km will be in Alberta.

These pipelines transport condensate (C5+) and natural gas liquids (NGL) (C3+) from NorthRiver Midstream’s Highway Liquids Hub, northwest of Wonowon, B.C., to the Gordondale area of Alberta.

As part of the project, several major HDD crossings were required. Pre-construction planning support, trenchless engineering and design, trenchless construction inspection and drilling fluid waste management was performed by BlueFox Engineering.

Major trenchless crossings on the project:

Stoddart Creek: 906m in length, with both horizontal and vertical curvature. Parallel NPS 8 / NPS 10.
Fish Creek: 1,022m in length. Parallel NPS 8 / NPS 10.
Peace River: 3,026m in length. The longest HDD installation in Western Canada and the longest on the project. Includes telescopic surface casing and two HDD rigs utilizing the intersect method. Parallel NPS 10 / NPS 12.
Forest: 1,152.4m in length. Over 200m of vertical elevation gain from entry to exit. Parallel NPS 10 / NPS 12.
6 Mile: 520m in length. Bundled NPS 10 / NPS 12.
Trib to 6 Mile: 400m in length. Parallel NPS 10 / NPS 12.
8 Mile: 766m in length. Bundled NPS 10 / NPS 12.
Kiskatinaw River: 2,045m in length. The 3rd longest HDD installation on the project. Two HDD rigs utilizing the intersect method. Parallel NPS 10 / NPS 12.
Pouce River: 2,101m in length. The 2nd longest HDD installation on the project. Two HDD rigs utilizing the intersect method. Parallel NPS 10 / NPS 12.
McMahon Slope: 600m in length. Over 110m of vertical elevation gain. Parallel NPS 8 / NPS 10.
Johnson Road: 457m in length. Deep gravels with telescopic casing. Bundled NPS 10 / NPS 12.
KP121: 1,642m in length. Parallel NPS 8 / NPS 10. One of the longest single sided crossings utilizing a 240,000lb HDD rig in Canada.
Henderson Creek: 311m in length. Parallel NPS 8 / NPS 10.

The advanced portion project started in the late summer of 2025 and focused on completion of the HDD installations, prior to mainline pipeline construction. Combined, all major crossings were completed on schedule by the Spring of 2026. The project is regulated by the Canadian Energy Regulator and by the British Columbia Energy Regulator.
