• Crude Tank (Floating Double Deck Pontoon) is preparing to take crude oil (API29) for the first time. Is it safe to put crude directly in to the tank without Oxygen freeing? If water is first taken into the tank up to the floating level and then charge the crude, is it more safer?

  It's possible to ensure a safety operation controlling the speed in the feed nozzle of the tank, there is some references which presents the maximum flow rate to ensure the filling the tank with controlled speed in order to minimize the vapour formation in the tank, of course, this flow rate depends on the diameter of the feed nozzle of the tank.
