Interactive risk assessment framework of transmission gas network
FY 2024-25
Summary
Reliability of the pipelines is compromised due to natural ageing and deterioration processes. The failure incidents reported in Canada are metal loss (corrosion, erosion), cracking (pipe fittings/joint failure), external interference (accidental, vandalism), material manufacturing/construction, geotechnical failure (slope movement, weather) and other causes (operational). Predominant failure mechanisms reported are metal loss (e.g., due to corrosion) and geotechnical failure (loss of integrity due to geotechnical effect) account for over 50% of failure incidents. Quantifying corrosion progress and failure risk assessment is subject to significant uncertainties. Understanding performance of the different pipelines and their interaction with the environment (as the failures can manifest as leaks and spills) is important to support decisions about risk mitigation, future development, investments, and maintenance policies - all of which are important so that pipeline operations can be made more efficient and reliable.
