Here’s an update to the original 2012 article introducing the essential elements of pipeline risk assessment. Little has changed–the originally introduced elements seem to be robust and comprehensive, as suggested by having weathered a few years of scrutiny now. PIN_March_2018_Kent_Muhlbauer
Armed with a modern risk assessment, risk management becomes much more transparent and even exciting. Seeing cost/benefits of proposed risk reduction actions provides clarity and, often, some ‘ah-ha!’ moments. Please click this link to read the pdf file of this article.
Risk assessment on any facility is most efficiently done by first dividing the facility into components with unchanging risk characteristics. For a cross-country pipeline, this involves collecting data on all portions of the pipeline and its surroundings and then using this data to ‘dynamically segment’ the pipeline into segments of varying length. Risk algorithms are […]
A rather common issue these days is decision making involving comparisons between In Line Inspection (ILI) vs Direct Assessment (DA, and, in particular, External Corrosion DA or ECDA). You may need to research these techniques, if not already familiar to you, since we will assume the reader is fairly familiar with both. Both are acceptable […]

Probability of Failure Based on Basic Engineering Principles All plausible failure mechanisms must be included in the assessment of PoF. Every failure mechanism must be properly measured by independently measuring the following three elements: Exposure (attack) – The unmitigated aggressiveness of the force or process that may precipitate failure. This includes external forces, corrosion, cracking, […]
