While there are a number of visual techniques that can help in interpreting large amounts of data, many graphical analyses provide little to no value for in-depth risk assessment. Here we explore some common graphical techniques and discusses why they can’t replace data analyses in risk management. Seduced by Graphics: The Myth of Risk Management […]
The Outlook for Pipeline Risk Assessment A 2014* Interview with W. Kent Muhlbauer *but still relevant! PHMSA has recently expressed criticism regarding how Integrity Management Plan (IMP) risk assessment (RA) for pipelines is being conducted. Do you also see problems? There is a wide range of practice among pipeline operators right now. Some RA is […]
Risk Concepts sometimes harbor challenges in understanding and communications. This means that we must employ extra care in our choice of language when discussing risk issues. Read the article (pdf file)
Unfortunately, the US guidance documents for pipeline risk assessment are still not up to date. This continues to be a source of confusion for some and frustration for others. Please click this link to read the pdf file of this article.
There is currently great disparity in approaches and level of rigor applied to risk assessment by pipeline operators. This is largely due to the absence of complete standards or guidelines covering this complex topic. The disparity leads to inconsistent and problematic risk management, as was discussed in a previous column. Most operators desire sound and […]
Tackling specifics of pipeline risk in bite-sized portions to make this challenging subject more approachable. Troubles with Weightings There is currently great disparity in approaches and level of rigor applied to risk assessment by pipeline operators. This is largely due to the absence of complete standards or guidelines covering this complex topic. The disparity leads […]
Ever consider that true risk management sometimes occurs only at the lower levels of some pipeline organizations? That is, personnel performing field activities are in effect setting risk levels for the company. Their choices of day-to-day activities are essentially driving risk management and thereby establishing corporate risk levels. This is not just theoretical—real choices are […]
In the first part of this discussion, we hopefully dispelled some myths about low data availability. We discussed how reasoning is used to generate data and how many useful pieces of risk insight emerge from even simple pieces of knowledge. We also contrasted a statistical approach to risk assessment with a physics based approach. The […]
In the first installment of this column, we introduced the concept of pipeline risk assessment Essential Elements. This is a list of ingredients that arguably must be included in any pipeline risk assessment. In this installment, let’s examine “I can’t do good RA because I don’t have enough data.” There are at least two aspects […]
Perhaps first question is this: ‘is your scoring system really giving you new knowledge and useful insights into actual risks?’ If not, then that alone should be a compelling reason to change—especially when modern risk assessment is both more efficient and less expensive.
