L52314 Pipeline Defect Assessment - A Review and Comparison of Commonly Used Methods

There is a need in the industry in assessing the severity of a particular anomaly (dent, gouge, corrosion pit, etc.) in a pipe as to whether or not repair or removal is warranted. Along with the determination of repair there is also a need for prioritizing in-line-inspection (ILI) data, and for making remaining-life assessments of said pipe.

This document catalogs analysis methods and computational tools for addressing defects and damage discovered on in-service pipelines. It includes example calculations where closed-form algorithms are available in the public domain. It lists and describes solution techniques not available in the public domain, and it provides information so that users can either acquire the relevant software or pursue assistance regarding a particular defect assessment technique.
