Abstract: To address the potential safety risks induced by foundation settlement and structural deformation during the operation of storage tanks at the Nanning Oil Depot, and to overcome the limitations of conventional monitoring methods—such as limited spatial coverage, poor real-time performance, and insufficient accuracy—this study develops an intelligent monitoring system that complies with the safety standards of the oil and gas industry. The system is designed to support tank integrity management and ensure the long-term safe and stable operation of the depot. Built upon the intelligent safety risk management and control platform of the Nanning Oil Depot, the system integrates three complementary technologies: fiber Bragg grating (FBG) sensing, Interferometric Synthetic Aperture Radar (InSAR), and an industrial internet platform. The implementation strictly follows national standards including GB 50026 and JGJ 8, and the system performance was rigorously verified through both Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT). The monitoring system enables 24/7 continuous real-time surveillance of foundation settlement and structural deformation, with a data transmission delay ≤ 0.1 s, static measurement accuracy of 0.1 pm, and full-depot InSAR coverage achieving millimeter-level precision. The system incorporates user authority management, real-time equipment status visualization, and early warning capabilities, enabling automatic identification of out-of-limit data and generation of alert reports. During the trial operation, the system demonstrated stable performance. The multi-technology integrated monitoring system effectively compensates for the shortcomings of traditional monitoring approaches and achieves a synergistic “point-area combination and real-time-global coverage” monitoring strategy. Its technical performance reaches the domestic advanced level and can be promoted as a standardized solution for integrity management of oil and gas storage tanks. This system not only provides reliable safeguards for the safe operation of tanks at the Nanning Oil Depot but also offers a practical reference for the intelligent monitoring upgrade of oil and gas storage facilities, and holds significant implications for advancing the digital transformation of safety risk control in the oil and gas industry.
