Tony da Costa, vice president of engineering at Mobiltex (Calgary, Alberta, Canada), and Shawn Lawrence, service manager, join the MP Interview Series to discuss lightning immunity in pipelines, as well as the use of remote monitoring systems to evaluate potential damage. In this episode, they cover the ways in which a lightning strike could affect a pipeline. 

Other topics explored in this roundtable discussion include why "flashovers" are often more damaging than a direct lightning strike; ways to evaluate the impact of a lightning strike; and how pipeline operators can protect cathodic protection (CP) systems and their components from lightning strikes. 

The feature article from the February 2021 print issue of Materials Performance (MP) Magazine has more on these subjects.
