Case: Pacific Gas and Electric Company Pipeline Rupture and Fire
In 2010 in San Bruno, California a Pacific Gas & Electric national gas pipeline ruptured
killing eight people. This is a very high profile pipeline failure in the U.S. Everyone in the
pipeline industry knows about it and doesn’t want to be the next PG&E.
The U.S. National Transportation Safety Board Accident Report stated:
“PG&E's pipeline integrity management program, which should have ensured the safety of
the system, was deficient and ineffective because it –
•
Was based on incomplete and inaccurate pipeline information.
•
Did not consider the design and materials contribution to the risk of a pipeline failure.
•
Failed to consider the presence of previously identified welded seam cracks as part of its
risk assessment.
•
Resulted in the selection of an examination method that could not detect welded seam
defects.
•
Led to internal assessments of the program that were superficial and resulted in no
improvements. “

Summary
Screening encodes known risk factors in
re-usable, extendable models.
Dramatically improves process effectiveness
One matrix ensures balanced judgement of risk
Aligns the qualitative and quantitative
assessments on a common frame of reference

Data management at every step, evaluation to jump to next
Need for qualitative judgement increases
for each step
Risk Result
Each step require data transformation and
appropriate models. Insecurities are
implied, i.e. spatial generalisations or
applicability of model assumptions.
Therefore, both the significance and need
for careful qualitative judgement increase.
