Pipelines have been in the news a lot lately.  Yet, despite the coverage, the obvious damage, claims and counter-claims, it’s difficult to understand these events in the overall context of pipeline safety without looking at longer time frames. Fortunately, the Pipeline and Hazardous Materials Safety Administration (PHMSA) maintains a comprehensive database of all pipeline incidents reported in the U.S.

Using data from 1993-2012, we focused on onshore and offshore pipelines carrying hazardous liquids (primarily crude oil and refined petroleum products) that suffered what PHMSA classifies as “significant incidents.” To qualify, a “significant incident” must satisfy one or more of the following criteria:

  •        a fatality or injury requiring in-patient hospitalization
  •        $50,000 or more in total costs, measured in 1984 dollars
  •        highly volatile liquid releases of 5 barrels or more, or other liquid releases of 50 barrels or more
  •        liquid releases resulting in an unintentional fire or explosion

Of 5,727 reported incidents during 1993-2012, 2,079 met the PHMSA definition of “significant incidents,” accounting for 99.4% of the total volume spilled.
