The protection has been implemented on Abriox’s Merlin cathodic protection (CP) monitor. This telemetry-based instrument is one of the most widely used field devices for remotely monitoring the anti-corrosion CP systems that are installed on pipelines, storage tanks and other buried metal infrastructure used in onshore oil and gas networks.
“Pipelines are a significant attractor for lightning, and in some regions of the world strikes can occur frequently. We’ve always had lightning protection on our corrosion monitor, but the only feedback we ever got on how it performed in the real world tended to be when a burnt-out unit arrived back from the field,” says Jason Hanlon, Technical Director of Abriox. “How much energy was present, what the shape of the energy surge was, whether it arrived directly or indirectly remained a mystery – and we decided that it would be a good idea to better understand the risk by talking with lightning experts.” Read entire article
