The issue of induced AC current corrosion and its mitigation for buried pipelines has seen increased interest and rapid development of new technologies for mitigation and monitoring in the last 5 to 10 years. These include work on development of a NACE International Standard Practice for AC current corrosion on cathodically protected pipelines updates to the AC corrosion mitigation design criteria new materials and installation methods and AC corrosion current density remote monitoring technologies.This paper presents a comparison of the design methods and mitigation technologies that were used in the past and those that have been developed and continue to evolve to meet the current challenges faced by the buried pipeline operators.

Keywords: AC corrosion; AC mitigation; AC corrosion current density; AC current density remote monitoring; AC coupon; ER soil corrosion probe. corrosion, humid air, carbon steel, stainless steel
