Recent years have seen advances in controlling external corrosion for buried pipelines. Specialized equipment and methods for assessing cathodic protection effectiveness and AC corrosion threats, state-of-the art corrosion sensing equipment, remote monitoring dataloggers, and advanced modeling techniques offer operators technologically advanced means and methods for managing external corrosion risks. While proof of compliance continues to rely on long-established field tests and monitoring cycles, there are opportunities to improve external corrosion management programs to incorporate advanced technologies and methods. This paper presents a case study demonstrating the Enbridge Integrated External Corrosion Management (IECM) methodology for a 12-inch, 85-mile-long crude oil pipeline located in North America. Pipeline construction, external corrosion history, modeling, field validation assessment, and resulting IECM protocols are presented and discussed.
