Join Philip Hestvik, as he provides an overview of the Mackenzie River HDD Pipeline Crossing Replacement Project completed by Enbridge in 2018 in the Northwest Territories.

The Enbridge Line 21 Segment Replacement Project replaced 2.5 kilometers of pipeline below the Mackenzie River using intersect horizontal directional drill technology. Through a partnership with local Indigenous communities, a joint environmental management committee was formed to focus on protecting the land and water, and support local training and employment. On September 27, 2018, the Norman Wells Pipeline was restarted successfully. Successful execution of this Project required creativity to overcome logistical challenges. The intersect drill spanned over 2100 metres. Due to the remote location and sensitive environment, equipment was barged to one of the worksites and over 14,000 wooden mats were used to construct an 11 kilometre road. The construction window was short and the intersect drill was highly technical. This presentation will focus on the construction aspects of the Project.
