Dear All,
I am trying to understand the root cause driver behind the requirement to activate the vacuum safety valves on the floating roof tank rood when the roof lands on the tank's bottom, is it due to the sudden displacement of the liquid and the risk of tank's implosion due to the depletion of the liquid from the tank once it lands. Any reference to the same in API 650 or 620?
Thanks alot
