From pipeline inspection data to insight

To ensure oil and gas pipelines operate safely, instrumented inspections and assessments are completed on a recurring frequency. A common and valuable inspection method is In-line inspection (ILI). This form of inspection uses a measurement device (ILI tool) that is propelled through the pipeline by product flow and the tool identifies and sizes anomalous conditions along the inside and outside walls of the pipeline that could affect the pipes ability to contain the product. Anomalous conditions can include metal loss corrosion, deformations, cracking, weld defects, and other defects on pipe welds. The results of an ILI survey are used in the determination of repair and replacement locations for a pipeline. The purpose of this project is to study the data from multiple historical ILI surveys, subsequent corresponding non-destructive examinations (NDE) reports, and basic pipe attribute and operating data to assess if any trends, patterns, or commonalities can be determined.
