More than 210 trenchless professionals made the trek to Edmonton, the provincial capital of Alberta, Nov. 10 for the North American Society for Trenchless Technology Northwest Chapter’s 20th annual Northwest Trenchless Conference.
One of the highlights of the events is the announcement of the 2016 Northwest Trenchless Project of the Year. The project of the year highlights a project located within Alberta, Saskatchewan, or Manitoba, which took place between November 2015 and November 2016.
This year, the prize went to the Northern Courier Pipeline Project for TransCanada Corp.. Consulting engineer for the project was CCI Inc. and the HDD contractor for the project was Michels Canada.
The project consisted of several large watercourse crossings. The largest crossing identified was the Athabasca River, Located north of Fort Mackay. This crossing would be a milestone for the HDD Industry in North America due to its combination of the length of crossing and required borehole diameter, 2196 m and 54 in. respectively. In fact, it is considered one of the longest 42-in. HDD installations ever executed in the world.
Due to the complexity and scope, significant pre planning was conducted, evaluating feasibility. The crossing would serve as a casing pipe for a high temperature NPS 24 pipeline. The NPS 24 pipe was installed inside of the NPS 42 pipe and grouted into place. The grout system was required to prevent buckling in the pipe due to the high temperature. The HDD construction required the combination of newer installation techniques to achieve the final goal. The success of this project was due to the fact that the engineering team and the contractor worked in synergy during the construction phase to successfully finish the crossing.
In addition to the project of the year discussions, there were 11 technical presentations covering a wide range of topics from case studies in pipe rehabilitation, microtunneling, and horizontal direction drilling, as well as studies on SEM tunneling, guided boring, sustainable growth, clogging and drilling waste reduction.
All events took place at the Fantasyland Hotel at West Edmonton Mall.
