As part of its ongoing continuous improvement efforts, TransCanada has analyzed the system-wide historical failure data to understand trends and benchmark risk algorithms. The analysis of historical in-service and hydrostatic-test failures is a good diagnostic tool to assess threats to the pipeline system. This knowledge and understanding can be used to build risk algorithms. Quantification of failure rates also enables risk values among different threats and along the pipeline to be benchmarked appropriately. This paper focuses on the assessment of the expected failure frequency of the pipeline to SCC and corrosion.
