Resumo

Este estudo investiga o comportamento eletromagnético de tanques de teto flutuante externo submetidos a uma descarga direta de raio de 200 kA. Utilizando eletromagnetismo computacional, calcularam-se os campos elétricos e magnéticos para dois cenários: com e sem o uso de condutores de bypass, conforme recomendado pela API RP-545. Os resultados das simulações revelaram que, na ausência de condutores de bypass, os valores do campo elétrico na junção entre a parede do tanque e o teto flutuante ultrapassam 200 kV/m, aumentando o risco de ignição. A implementação dos condutores de bypass reduziu significativamente a intensidade do campo, demonstrando sua eficácia na mitigação de riscos de incêndio em ambientes de armazenamento de líquidos inflamáveis.
