Patent grant awarded by the pipeline design institute for the invention titled “Intelligent Monitoring Methods and Systems for the Whole Life Cycle of LNG Storage Facilities”

Thread Content

This patent proposes an intelligent monitoring and safety risk prevention system that covers the entire lifecycle of low-temperature LNG storage facilities, encompassing various aspects such as the deployment of monitoring sensors, data collection, and data analysis. This system enables real-time monitoring of the key parameters of the reservoir by installing sensors in the surrounding rock around it, as well as deploying devices inside the chamber and on the inlet and outlet pipes. On this basis, the solution also incorporates functional modules that create a complete closed loop from data collection to risk management, providing technical support for the long-term stable operation of low-temperature LNG storage facilities. This technology boasts advantages such as high specificity, high reliability, ease of operation, low cost, and wide applicability. It has a high tolerance for geological conditions, and it effectively solves the long-term stability issues associated with low-temperature LNG storage facilities caused by the freezing of rock masses at low temperatures. It also addresses other technical challenges that have plagued the industry for a long time, including risks related to the frozen zone, storage facility stability, and LNG leakage. This patent forms a high-value patent portfolio together with other invention patents already authorized by the pipeline design institute, such as the \"Method and System for Converting Abandoned Tunnels into Liquefied Natural Gas Storage Facilities\" and the \"Method and System for Controlling the Freezing Zone of the Fractured Rock Surrounding Underground Natural Gas Storage Facilities\", thereby creating a comprehensive protection network of \"core + peripheral elements\" that further strengthens and enhances the overall technical value. This patent portfolio can be swiftly applied to the development of China’s natural gas storage and liquefied LNG industry chain, effectively reducing the costs associated with storing natural gas and liquefied LNG while improving economic efficiency; it provides strong technical support for the healthy development of the industries related to gas storage and the utilization of underground space.
