According to the NACE SP21414 and ISO18086 standards, AC corrosion risks on pipelines requires knowledge of both the AC and CP current density at a coating defect (or coupon). Field data, pipeline and powerline properties are used to calibrate the computational model such that the computed simulation results are aligned with real-world data.
In this technical article Christophe Baeté and Gerald Haynes explain how remote monitoring and computational modelling can help operators transition into the digitalisation of pipeline AC corrosion control.
