With over 11,000 assessments on 410k miles of pipeline from 17 pipeline operators and 34 inline inspection (ILI) companies, OneBridge Solutions (now Irth Solutions) is believed to have amassed the largest and most diversified set of ILI data in the industry. This paper presents insights gleaned from the analysis of said ILI data, with the focused aim of determining what variables contribute to high ILI system performance, specifically for technologies that characterize metal loss, i.e., ILI company, technology, metal loss depth, metal loss classification, etc. These insights are presented to achieve the foremost goal of shared learning and provide valuable information that all stakeholders can utilize to improve pipeline integrity.
