AC corrosion: looking in the right direction
(World Pipelines, January 2021)

Description

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.
