Pipeline AC Mitigation & Stray Current DC Interference

Electrical Interference Mitigation - Working to ensure the safety of pipeline infrastructure in shared corridors

AC Mitigation – It is no secret that finding space to construct the new pipeline infrastructure needed to meet today’s growing energy demand is becoming increasingly difficult. That is why existing High Voltage Overhead Power Line corridors are attractive options for shared right of ways. Pipelines buried in close proximity to power lines have the potential to pick-up AC current causing a potential shock hazard for the public or personnel and raising the risk of AC corrosion, resulting in the need for AC mitigation.

Stray Current DC Interference – For DC power lines the pipelines may be subjected to unwanted stray current DC interference requiring detailed site testing and monitoring and mitigation.

Corrosion Service specializes in understanding electrical interference on pipelines, and in conjunction with the most advanced modeling software, is capable of providing industry leading stray current DC interference or AC mitigation system designs that improve safety and reduce the risk of AC Corrosion, mitigate safety risks and eliminate harmful interference.

Protecting your assets for years to come.

Service Profile - Design Services

System optimization is critical for AC Mitigation and stray current DC interference designs to ensure the proper system components are selected, sized and strategically located to provide efficient current discharge for the pipeline asset to be mitigated.

Our long history of design and complete understanding of the AC interference and stray current DC interference, having designed numerous mitigation systems over the years for various structures in North America and around the world give our present and future clients the confidence in Corrosion Service. 

Our Design teams consist of NACE trained and certified professionals having all the skills to complete the job. Our Engineering and Drafting services and as well support staff follow defined work flows that allow full exposure to internal and external auditors confirming system excellence prior to installation.

Having established and document work flows for the entire design process ensures our process is transparent and instills confidence that the designed system will exceed the clients expectation once installed for many years to come.

Service Profile - Installation Services

We have dedicated crews that are trained in the installation of stray current DC interference and AC mitigation systems. Projects range from installing a single sacrificial anode, AC mitigation wells, kilometers/miles of AC mitigation bare copper wire or zinc ribbon as per the design requirements.

To ensure the work in is completed on budget and on time we own a fleet of construction equipment and have partnered with specialised prequalified contractors that have the required skills to assist us in completing the job.

Service Profile - System Commisioning and Annual Maintenance Survey

Efficiency and effectiveness of the stray current DC interference or AC mitigation system design and installation is a thoroughly evaluated when the system components are commissioning and the commissioning survey is undertaken.

Following defined project commissioning or test procedures, all components are reviewed, documented and once technical parameters are met, the system is energized to achieve design parameters.

Having trained and qualified staff is critical in completing this work and Corrosion Service has specialized crews that are NACE trained and certified for completing commissioning reporting, compliance inspections, annual and  maintenance surveys.

All data obtained from site is reviewed and a technical analysis is completed by specialist engineers and information is included in a detailed report for the clients review and issue with confidence to regulators.

The Corrosion Service Technical Library that Documents our Past and Defines our Future

Corrosion Service has and remains a leader in the corrosion control industry, supporting the various industries in North American and around the World, ensuring asset integrity by providing responsible engineering services. As part of our continued commitment we would like to welcome you to our electronic Library as the place to view our AC mitigation and stray current DC interference technical papers written and presented over the past 69+ years that have supported the corrosion industry advancement.

We converted a prime corner office into a Library at our Head Office and dedicated the room to Sorin Segal because of his commitment to Corrosion Service, the numerous papers presented, the engineering mentoring within Corrosion Service and to our industry.

We would be pleased for you to come and view this comprehensive library that includes various text books, relevant publications, all NACE Materials Performance magazines presented since first publication, technical bulletins and various other related corrosion related print material.

Since our founding in 1950, we have built an extensive portfolio of specialist products for the corrosion prevention industry.

Our materials supply team has access to a full-range of DC interference and AC mitigation materials both manufactured in-house and sourced from partner suppliers. Our dedicated supply chain team is based in Toronto alongside our material distribution hub, which is capable of delivering materials throughout the world on short notice.
