As we continue this exploration of pipeline risk assessment, let’s tackle some terminology obstacles. Pipeline risk assessment is a challenging topic on its own, so added confusion from terminology is most unwelcome. Background In some recent regulatory initiatives, a criticism has arisen regarding some pipeline operators’ failure to properly account for ‘threat interaction’ in their […]
Results for PoF
Probability of Failure
Ok, so how do I convert from TTF to PoF?
This is one of the more challenging aspects of modern risk assessment. One of the keys is to select the future date for which the PoF is being estimated. This is often ‘next year’ but can really be 5 years, 10 years, 20 years, etc into the future. Another key is to ensure that both likely and […]

The Basic and Critical Elements of PoF Estimation
Probability of Failure Based on Basic Engineering Principles All plausible failure mechanisms must be included in the assessment of PoF. Every failure mechanism must be properly measured by independently measuring the following three elements: Exposure (attack) – The unmitigated aggressiveness of the force or process that may precipitate failure. This includes external forces, corrosion, cracking, […]
