Understanding pipeline risk - Improving integrity management and increasing public safety

DNV, in collaboration with W. Kent Muhlbauer, introduced an important set of guidelines to address aspects of pipeline risk assessment not well developed in existing industry standards – guidelines that optimize the risk assessment efforts of both operators and regulators. 

About the Essential elements of pipeline risk assessment report

This report sets forth essential elements for a pipeline risk assessment. Their utilization ensures that meaningful risk estimates are produced. Furthermore, the adoption of these minimum elements facilitates efficient and consistent regulatory oversight and helps manage the expectations of all stakeholders.

Our guidelines offer a formalized process with logical, structured approaches to efficiently integrate all available information into a robust risk assessment. The guidelines are intentionally concise yet flexible, allowing tailored solutions to situation-specific concerns. At the same time, an appropriate level of standardization is incorporated to manage expectations of regulators as well as those subject to the regulations.

The application of these elements is easy and intuitive, as is illustrated in a sample case.

DNV is a global leader in integrity and risk management while Mr Muhlbauer is a leading authority on pipeline risk management. This joint effort provided an immediately useful set of common-sense tactics to make risk assessment more meaningful, defensible, and acceptable to regulators. We have oriented these guidelines to directly satisfy PHMSA’s stated goal of smarter risk assessment.
