Abstract: The integrity of pipelines with longitudinal seam welds has received renewed interest by operators and regulators, due primarily to a number of high-profile incidents. Most operators and pipeline integrity consultants have assessed seam weld flaws with methodologies that have changed very little over the past 30 years. However, the status quo is no longer viable, given the heightened public scrutiny and regulatory pressure.
This paper presents a number of recent innovations in assessment technology that can lead to improved reliability and a more optimal use of finite integrity budgets.

Keywords: integrity of pipelines, longitudinal seam welds, conservative flaw assessment model, advanced assessment, ln-sec model, finite element parametric study, pressure cycle fatigue analysis
