Over the past three years there has been increasing industry interest and profile regarding the role and pipeline integrity management potential of EMAT crack inspection technology in the Oil & Gas pipeline industry. This paper outlines the stages and results of the effective collaboration of a major pipeline operator and a service company to advance the true predictive performance of the PII’s EMAT crack inspection technology. The paper will also summarize and provide examples of lessons-learned from this collaboration across all stages of EMAT based SCC integrity management program. The paper will similarly outline ongoing work in progress regarding the assessment of the ILI data relative to hydrotesting equivalency, detection of injurious defects and the related analysis and reporting improvements made over the past three years.
