Cathodic Protection Optimization Using Integrated External Corrosion Management

Monitoring and maintaining cathodic protection systems is a significant effort for operators each year. Annual survey locations are typically established at features such as casings and foreign pipeline crossings where abnormal operating conditions could result in elevated corrosion rates. Additional test stations are commonly located such that a maximum spacing is not exceeded and installed at locations of convenience, but it is unclear which test station locations provide meaningful data with respect to external corrosion risk. This paper reviews findings of a collection of case studies performed by the Integrated External Corrosion Management (IECM) team since 2021. Process improvements, assessment results, and high-level economic analysis for selected case study pipeline segments will be reviewed and discussed.
