Why Is Fuel Tank Lightning Protection Important? - Lightning Eliminators. A Floating roof tank (FRT) is a type of tank used for the storage of large amounts of petroleum products such as crude oil to allow any trapped gas within the oil to escape, as this stabilizes the crude oil. The FRT has an open top which is equipped with a steel roof which moves up and down according to the level of the stored petroleum product in the tank. The floating roof edge is rounded with a rim seal that has a function of preventing the flammable vapor of the stored product from escaping outside the tank and mixing with air, which helps to prevent fires from occurring.
The tank seal is made of flexible insulating materials of different designs. Destructive lightning events do not need to be a direct strike to the tank itself. A nearby strike can create a massive voltage potential rise across the tank surfaces, including the shell and the floating roof. Sadly, shunts are extremely unreliable and are not easily inspected except through a maintenance event.
