A recently granted patent (Publication Number: US11959593B2) outlines a detection method for identifying leaks in sealed, thermally insulating tanks used for storing liquid gas. The method involves injecting inert gas into the insulation space, removing inert gas, and calculating variations in mass to determine potential leaks. The system triggers an alarm if the difference in mass variations exceeds predefined thresholds. The patent also describes variations of the method for tanks with primary and secondary sealing membranes, as well as insulation spaces, each filled with solid insulating materials and inert gas. The method includes measuring temperature and pressure in the insulation space to accurately assess the presence of leaks.

Furthermore, the patent details an installation for liquid gas storage that incorporates the detection method. The installation includes pressure sensors, temperature sensors, flow measurement devices, and leak detection devices to monitor inert gas flow, mass variations, and trigger alarms in case of leaks. The system is designed to ensure the safety and integrity of liquid gas storage by providing early detection of leaks in both primary and secondary insulation spaces. Additionally, the patent extends the application of the detection method to liquid gas transport ships, highlighting the potential for widespread implementation of this innovative leak detection technology in the industry.
