Submerged shunt for lightning protection of naphtha tank

Submerged shunt for lightning protection of naphtha tank

Submerged shunt for lightning protection of naphtha tank

(OP)
Hi everyone, I am new to this forum.

Our plant is planning to install submerged shunt in our naphtha tank to enhance the lightning protection.
However, some managers doubt the effectiveness of the submerged shunt compared to the conventional above-deck shunts which we are using.
They said the cost of installation is high and it is impossible to do the inspection or maintenance work for the submerged shunt.
We have to find out is there any oil company using submerged as lightning protection.
However, the information is very limited in the internet.
We would like to see if anybody can provide relevant information for our reference?
Thanks very much.

RE: Submerged shunt for lightning protection of naphtha tank

Submerged shunts seem to enhance lightning protection for open Floating Roof Storage Tanks.

Depending of course on the grade of naptha, many tank owners use a dome type (closed) internal floating roof tank with nitrogen blanketing.

Is your naptha storage tank a FRT ???

The tank type affects the choice of lightning protection ...

Thanks MJCronin for your reply.

Our tank is a external floating roof.
Is it the same to the open Floating Roof Storage Tanks?

Also, is there any tracked or proved record showing that it is more reliable than conventional shunts?

Thanks very much.
