PHMSA (the U.S. Pipeline Hazardous Materials

criticism regarding how Integrity Management
Plan (IMP) risk assessment (RA) for pipelines is
being conducted. Do you also see problems?

But if I need to estimate (quantify) how often a
pipeline segment will fail from a certain threat,
dont I need to have numbers telling me how
often similar pipelines have failed in the past
from that threat?

What about the concern that a more robust
methodology suffers more from lack of any data?
(i.e. If I dont have much info on the pipeline,
I may as well use a simple ranking approach.)
