The Integrity Management Cycle

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. “

Robust risk based decisions

One matrix ensures balanced judgement of riskAligns the qualitative and quantitative assessments on a common frame of reference

Screening encodes known risk factors in re-usable, extendable models.Dramatically improves process effectiveness

The structured risk process ensures accountability and traceability throughout

Engineers’ judgement is paramount,all assessments require reasoning.We don’t believe in “the risk button”

SilverPipe offers data managementat every step

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.

Need for qualitative judgement increases for each step
