Deploying inspection device into liquid storage tank using vapor suppression
A recently granted patent (Publication Number: US12011626B2) outlines a method for deploying an inspection device into a vessel containing a fluid. The process involves forming a vapor suppression layer on the fluid, displacing gases within the launching system and vessel with inert gases like nitrogen, argon, or carbon dioxide, and passing the inspection device into the fluid. The method includes steps such as transitioning the closable chamber of the launching system, lowering the inspection device through different volumes within the vessel, and maintaining a slight overpressure before opening closures.
Furthermore, the patent details variations of the method for deploying an inspection device into vessels containing liquids or vaporizable liquids. These variations include forming vapor suppression layers using foam, displacing gases with inert gases, and passing the inspection device into the liquid within the vessel. Additional steps involve supplying cleaning fluids to wash the inspection device, closing and removing the closable chamber from the access passage, and maintaining overpressure within volumes. The patent emphasizes the use of specific inert gases and foam types for effective deployment of inspection devices into various vessel contents, ensuring safety and efficiency in inspection processes.
