AME completes emergency pipeline re-armouring in British Columbia

Aaron Merril Engineering Ltd. (AME) completed a bank armouring project on behalf of Pacific Northern Gas Ltd. (PNG) in Kitimat, British Columbia, Canada. An emergency pipeline re-armouring was needed to avoid potential damage to the line during the high-water season in the fall.

The project involved the installation of a rock apron that elevated and armoured the channel bed through the river crossing. The emergency nature of the project required AME to assemble the project, including management of design, procurement, permitting, and contracts, in an extremely tight timeframe. AME was able to achieve an accelerated project schedule and met all required deadlines. In-water work was required as pipe protection demanded visual verification by divers. This required special planning, safety equipment, and site-specific procedures for working in and around the river flows. A swift-water rescue team was present on-site to provide an additional layer of safety. Construction activities were performed on and around the high-pressure LNG line while it was in service.

Design and construction procedures were specifically tailored to allow for the armouring to be achieved while minimizing risk of damage to the line. This project demonstrated excellence in engineering and construction best practices; cost, schedule, and safety standards were achieved and exceeded.
