The Physics of CMI
Advancing Electromagnetic Technology for Remote Pipeline Inspection
The Current Magnetometry Inspection (CMI) method represents a significant advancement in the field of pipeline inspection research. Employed by leading pipeline operators across the globe, CMI has facilitated the successful inspection of thousands of kilometers of pipelines. This innovative method was developed through extensive collaboration with multiple pipeline operators, addressing their unique needs and overcoming existing challenges in pipeline inspection.
As a state-of-the-art electromagnetic survey technique, EMPIT specializes in the measurement and interpretation of electromagnetic far-fields. This expertise proves crucial when conducting Over-the-Line (OtL) inspections, where the distance between sensors and the test object can extend to several meters. Ensuring a high signal-to-noise ratio is essential for the accurate interpretation of far-field data.
CMI leverages the fundamental physical principle that a circular conductor generates a circular magnetic field when a current is passed through it. Anomalies in the pipeline wall lead to measurable anomalies in the magnetic field, which is applicable for horizontal and vertical bends, geometry changes, and metal loss in the pipe wall. As a result, EMPIT's advanced algorithms can translate the electromagnetic data into valuable insights for integrity and mapping assessments.
By utilizing in-house developed high-tech measurement equipment, intelligent analog and digital filtering, and Artificial Intelligence (AI) for data post-processing, CMI addresses significant industry challenges. This groundbreaking technology introduces a globally unique technique to the market, paving the way to survey the future and inspect the previously unpiggable.
