The Use of Surge Protective Devices in Mitigating the Effects of Lightning Strikes in Offshore Oil Applications


Recognizing the prevalence of lightning strikes in the Gulf of Mexico region, several system specifications and practices written for lightning mitigation have been applied and implemented in offshore applications over the last decade.

Little has been written about the induced transient secondary effects that occur as a result of inductive or capacitive coupling during a lightning strike. This paper will examine the links between the primary lightning strike and induced transient secondary effects. It will also discuss the mitigation of conducted transient effects in power and monitoring circuits through the proper application of surge protective devices (SPDs).
