Improve and Develop ILI Tools to Locate, Size, and Quantify Complex/Interacting Metal Loss Features

This project will provide the ability to accurately locate and size individual metal loss pits within an area of large corrosion and characterization of metal loss associated with dents/gouges and the longitudinal seam are three of the remaining problems with in-line inspection (ILI) integrity assessment of metal loss defects. The regulations address each of these type anomalies by requiring the remediation of the following: (1) metal loss with a calculated burst pressure less than the maximum operating pressure for liquid pipelines or 1.1 times maximum allowable operating pressure for gas pipelines; (2) any dent that has any indication of metal loss, cracking or a stress riser; and (3) corrosion of or along a longitudinal seam weld. The project team will use two measurement technologies and computer comparisons to investigate these three problems: a Multi-measurement ILI tool, state-of-the-art in-ditch nondestructive evaluation (NDE) measurements, and computer based comparisons of the technologies.
