Trunk Line 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 12km NPS 6 pipeline which connected TAQA’s existing facility site to a new facility site. An additional 3km NPS 6 pipeline was installed in the same ditch travelling between TAQA’s facility sites.

The route included three horizontal directional drills (HDD) of various watercourse crossings. The profile length of the drills ranged from 220m to 354m, with one of the drills bundled. 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.
