Pipeline Investigation P17H0011

Enbridge pipeline release

The occurrence

On 17 February 2017, there was a release of light crude oil condensate from an Enbridge pipeline in Strathcona County near Edmonton, Alberta. The pipeline was immediately shut down, along with other Enbridge pipelines in the area as a precaution. The product released (approx. 961 cubic meters) was contained in an existing excavation pit in an industrial property. No injuries were reported, and there was no fire. The TSB is investigating.

Jennifer Philopoulos has 15 years of experience in the Oil and Gas industry. She joined the TSB in 2015 as Pipeline engineering expert and senior investigator based out of the Dartmouth, NS regional office. She holds a bachelor's degree in Metallurgical Engineering from Dalhousie University.

Prior to joining the TSB, Jennifer began her career with Shell at their Oil Sands Upgrading facility, as a site materials and corrosion engineer. Most recently, she has worked as a consulting engineer, providing materials and corrosion expertise to the Oil and Gas industry.

Her experience has focused on corrosion assessments evaluating the conditions of materials in refineries and pipelines in order to prevent premature failures. This includes performing and developing risk based inspection programs, preventative maintenance programs and supporting fitness for service assessments. She has also preformed and supported metallurgical forensic work on various failed components.

Transportation Safety Board investigation process

There are 3 phases to a TSB investigation:

  1. Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
  2. Examination and analysis phase: the TSB reviews pertinent records, tests components of the wreckage in the lab, determines the sequence of events and identifies safety deficiencies. When safety deficiencies are suspected or confirmed, the TSB advises the appropriate authority without waiting until publication of the final report.
  3. Report phase: a confidential draft report is approved by the Board and sent to persons and corporations who are directly concerned by the report. They then have the opportunity to dispute or correct information they believe to be incorrect. The Board considers all representations before approving the final report, which is subsequently released to the public.
