Pipelines that are buried (or aboveground) and run with or cross HHVAC power lines in shared rights of way are subject to electromagnetically and fault induced AC currents. These unwanted but unavoidable AC currents present a risk of electric shock hazard to the general public or pipeline personnel and can give rise to destructive AC corrosion on affected pipelines.
Fortunately – the harmful effects of these AC currents can be controlled and mitigated against, ensuring safe and long service pipeline operation through the considered use of AC Mitigation Computerized Modelling and the design, application and maintenance of engineered AC Mitigation measures.
