C-FER's guidelines to PHMSA on quantitative pipeline risk models now publicly available

In 2016, C-FER conducted a project to review and report on quantitative risk models in pipeline and other industries for PHMSA, the US government agency responsible for regulating pipelines.  Based on the findings of the initial review, C-FER also developed guidelines for quantitative risk models for the pipeline industry.  Recently, the report describing all of this work has been made public and is now available for anyone to read!  The report can also downloaded directly from the PHMSA website (click here) and is also embedded below.

In this report you will find a number of interesting topics covered:

  • A set of guidelines to assist operators in developing or assessing QRA models is found in Section 5. The information in this section will be highly valuable to anyone implementing or improving a quantitative risk program as it provides recommendations on areas including:
    • Types of failure frequency models
    • Consequence measures for pipeline failures
    • Data collection, quality and management considerations
    • Risk analysis methods
    • Model verification and benchmarking
  • A review of quantitative risk analysis (QRA) models currently being used in the pipeline industry is provided in Section 3.
  • A review of the methodologies used in other industries such as nuclear, offshore, aviation and power transmission is found in Section 4.
  • A summary of a pipeline industry survey about current applications of risk models in industry and the desired attributes of an ideal risk model is given in Section 2.

    PIRAMID both meets and exceeds the best practices outlined in this report.  It has models for all of the threats outlined in ASME B31.8S and the report. PIRAMID uses the two most accurate categories of failure frequency models described in Section 5, which are historical or probabilistic in nature.

    The various failure scenarios including fires, explosions or toxic clouds are assessed to determine safety, environmental or financial risk along the line.  All of these measures can be aggregated by segment or viewed as a profile along the line for both system-wide and location specific assessments.
