n early 2019, ENTEGRA was called upon to assess the risk of intelligently inspecting
a 30 in. pipeline with the company’s ultra-high resolution (UHR) axial MFL/
CAL/IMU inline inspection (ILI) combination tool. This particular pipeline to be
inspected is part of a network of many others that enables the distribution of
natural gas across multiple states within the US. This specific segment runs through
approximately 20 active high consequence areas (HCAs) alongside major interstates,
residential and commercial areas. It distributes natural gas through and near wildlife
areas and protected lands. As a result of this, the pipeline segment – and others in
its network – falls under strict state and federal regulations. Therefore, it requires an
enhanced integrity management programme to keep it operating safely and efficiently.
Like many other pipeline operators, this company has very strict expectations and
requirements in their specification, primarily around metal loss features and a heightened
awareness and prioritisation of all anomalies found within HCAs. Because most of these
HCAs are expected to grow in size and the overall number of them will be increasing,
