we already deal with CIA Inspectors and they had performed remote inspection for our coke drums four times before.
I am asking about the extensive visual inspection with Dye Penetrate test and Implementing the required repairs in case that inspection results showed cracks in the coke drum welding.
If we installed the bottom unheading valves, could we bring / erect scaffolding inside the drum to perform these activities? and how?
would we have to deassemply the undeading valve to be able to bring scaffolding materials inside the drum?
