October 7, 2024 — Trans Mountain has entered into an agreement with Hifi Engineering (Hifi) to deploy a High-fidelity Distributed Sensing (HDS™) fibre optic network for comprehensive monitoring and enhanced leak detection on the Trans Mountain Expansion Project. The hybrid fibre optic network consists of a telecommunications cable paired with Hifi’s specialized optical sensing fibre and dual micro duct conduit.
“Trans Mountain is committed to continuous improvement in all facets of our operation,” said Jason Balasch, Vice President, Business Development and Commercial Services. “Our pipeline system was already monitored around the clock by two leak detection systems through our control centre in Edmonton. This agreement with Hifi provides our system another layer of leak detection and comprehensive monitoring utilizing their state-of-the-art technology.”
In addition to installing the fibre optic system for enhanced leak detection and intrusion monitoring, Trans Mountain and Hifi have signed a 10-year monitoring agreement. Under this agreement, Hifi will provide real-time monitoring support from its 24/7 operations centre.
“We are honoured to have this agreement with Trans Mountain to include 24/7 monitoring support of this multi-product infrastructure,” said Steven Koles, President and CEO, Hifi. “It represents a great showcase of the product agnostic distributed optical sensing and artificial intelligence and machine learning technology from Hifi which can be applied to all types of pipelines including conventional oil and gas, as well as carbon dioxide, hydrogen, and water.”
The Trans Mountain and Hifi initiative marks the world’s longest fully distributed fibre optic sensing deployment on a multi-product liquids pipeline.
Hifi’s HDS system, now substantially complete, has been under a progressive baselining and commissioning process since the completion of the Trans Mountain Expansion Project. This process leverages new automation and machine learning developed by Hifi to fully baseline normal pipeline operations.
The deployment includes surveillance support for leak detection, ground disturbance and security integrity risks, including right-of-way intrusion, strain monitoring, pig tracking and other operational applications. The fibre optic system can measure vibrations, temperature and pipe movement, continuously and accurately and can pinpoint the location of a suspected leak or other event within metres.
Trans Mountain’s pipeline system is also monitored by two computational systems, overseen by control centre operators and the leak detection group. Operators have the authority to shut down the pipeline in the event of a system alarm.
Trans Mountain and Hifi were recently recognized by the Fibre Optic Sensing Association (FOSA), receiving Project of the Year for this initiative.
