Unpiggable Pipeline Integrity: CMI’s Aboveground AC Magnetometry Calculates EIR-Free and Corrosion Risk

Current Magnetometry Inspection (CMI) uses multi-frequency AC fields, AI/ML, and dense aboveground sensing to 3D-map pipelines, calculate EIR-free, and distinguish passivated versus actively corroding defects—enabling targeted digs on unpiggable lines without disrupting CP or operations.
