DC Interference



It’s crowded out there and it’s only getting more crowded. The likelihood that your pipeline and CP system is experiencing stray currents from someone else’s pipeline is a sure bet. So what are the most common types of DC interference associated with corrosion? How do I best mitigate and monitor? Where do I get started? Well pardon us for interrupting, but you’re probably doing interruption all wrong. Let’s find out more in our half-day, three-part session tailored specifically to DC Interference.


Part 1 – Detection and Confirmation

This session describes common types of DC Interference associated with corrosion and illustrates diagnostic field tests that can be utilized in assessing suspected cases of interference. The presentation will focus on detection and confirmation of DC Interference using best practices associated with field measurement procedures. Attendees will be challenged to examine their current ECDA procedures to determine if adequate field data is being collected to correctly diagnose DC interference.


Part 2 – Mitigation and Monitoring

This session reviews common DC Interference mitigation methods and monitoring practices. Attendees will learn of several practical techniques used to mitigate confirmed DC interference issues as well as common mistakes made in attempting to mitigate DC Interference. This session will provide in-depth descriptions and illustrations of best practice methods associated with DC interference mitigation and monitoring including the use of coatings, sacrificial anodes, metallic bonds, and associated test stations.


Part 3 – DC Interference Threat Assessment

In the third session, you’ll learn how to implement a threat-based DC Interference mitigation and monitoring program to help you efficiently deploy your limited field resources. We’ll define a threat assessment framework and provide you with example use cases for applying the framework.


  • Learn about DC interference and how it affects your pipelines
  • Understand mitigation options
  • Discover how to implement a threat-based DCI mitigation and monitoring program


  • Pipeline Integrity and Engineers and Managers
  • Corrosion Managers and Engineers
  • Design and Construction Engineers
  • Compliance Managers


Attendees will receive 4 Professional Development Hours upon completion.
