Internal CP for a Jet Fuel tank
Internal CP for a Jet Fuel tank
(OP)
I am designing a jet fuel tank. It requires internal cathodic protection as per the client.The tank is internal floating roof type, having an aluminium roof over the floating roof. The Interla CP is to prevent corrosion from the very unlikely occurance of water inside. Tank and the product is suppoesed to be free of water, and a regular check and water draining and sampling facility is included in the design. It will have CP for below bottom plate prtection. My query is about the tank internal protection.
I have the following queries.
1. Is Impressed current CP is feasible for internalprotection of Petroleum storage tanks. The issue I find is the cable connection on the inside surface. are there any other concern on the safety for the cable taking inside.
2. As there are chances of water present ibside, if SACP is the selected option, I understand that Aluminium anode is the choice. However, for aviation fuels, Aluminium is not allowed to come in to contact with fuel, as it would contaminate the fuel.
I would like to know from the experts, your suggestions.

However, my second question is not answered. Whether impressed current CP is feasible for internal protection. How will the cable be taken to connect to the anodes inside?
Expecting your advice.
