Portions of a floating roof could have higher corrosion allowances (like the central deck, inner,bottom plate& outer rim of a pontoon, nozzles, buoys, appertunances exposed to liquid), while Top plates of Pontoons, external buoys not exposed to liquid etc. could have lower corrosion allowances.This, I believe is practised by designers just to reduce the weight of the roof.
Are there any other parts on the roof that will not require higher corrosion allowances?
