The emergence of fitness-for-service standards has created an opportunity to advance pipeline integrity assessment technology and methodologies. This paper describes modern approaches for assessing cracks and other planar flaws in pipelines. Many traditional approaches rely on simplistic characterizations and equations that have not evolved to take into account advancing technologies. For example, the NG-18 method dates from the early 1970s and is still widely used today. However, so-called conservative methods such as NG-18 can actually be unconservative in some instances, such as when used to determine hydrostatic testing intervals. This paper highlights today’s advanced approaches to pipeline integrity assessment. Case studies are presented illustrating the assessment of pipeline anomalies, such as crack assessment following hydrotesting and simulation of burst tests using a ductile fracture model.
