Abstract

This study investigates the electromagnetic behavior of external floating roof tanks subjected to a direct 200 kA lightning strike. Using computational electromagnetics, electric and magnetic fields were calculated for two scenarios: with and without the use of bypass conductors, as recommended by API RP-545. Simulation results revealed that electric field values at the junction between the tank wall and the floating roof exceed 200 kV/m in the absence of bypass conductors, increasing the risk of ignition. The implementation of bypass conductors significantly reduced the field intensity, indicating their effectiveness in mitigating fire hazards in flammable storage environments.
