O'Chiese Extension Pipeline

Project Overview

TAQA North (TAQA) retained Tridyne Projects Corporation to provide engineering, procurement, regulatory support and construction support for the installation of a new pipeline system and facility tie-ins.

The new pipeline system includes a 3km NPS 10 pipeline which extends TAQA’s existing pipeline to a new facility site.

The route included two horizontal directional drills (HDD) of various watercourse crossings. The profile lengths of the drills were 140m and 375m. These engineered crossings were completed by Tridyne’s trenchless design team.

Tridyne contracted the Stress Analysis, Cathodic Protection Design, and AC Mitigation Design.


Tridyne compiled and submitted the regulatory application on behalf of TAQA and provided full procurement services of materials and contractors for construction and installation.
