A recently granted patent (Publication Number: US11879598B2) discloses a method for determining the optimal parameters for cooling the internal space of a fluid-tight and thermally insulative tank designed to store liquefied gas. The method involves testing various values of parameters related to the cooling process until a fault is detected, with the chosen parameter being the one that results in the shortest cooling time without any faults. The process includes measuring pressure variables inside the tank and insulation barriers, comparing them to predefined thresholds, and detecting faults based on these comparisons.

Furthermore, the patent also covers a process for loading a ship equipped with such a tank, where the determined optimal cooling parameters are employed to cool the tank before loading liquefied gas. The loading process involves feeding the liquefied gas from a storage installation to the tank through insulated pipes. The method outlined in the patent aims to ensure efficient cooling of the tank to store liquefied gas safely, with a focus on minimizing cooling time and detecting faults in the process through pressure measurements and threshold comparisons.
