Abstract:

Objective It is to sort out a real-time monitoring system development scheme that can realize the risk management and control of the whole life cycle of the platform structure by studying the health monitoring technology suitable for the in-service jacket platform structure. Methods The actual monitoring data and numerical analysis results were compared, and the evaluation and early warning index determination methods were studied in combination with the actual management risk demand and actual monitoring effect. Results An integrated monitoring system and an independent remote monitoring system were designed. C++ programs, LabView tools and Beidou communication technology were used to achieve synchronous acquisition, storage and remote transmission of different types of data. A method of processing monitoring data through feature extraction and pattern recognition is found, so as to realize real-time evaluation and early warning of platform status mode and health status. Conclusion sIt is concluded that the system and method can effectively feedback the health status of the platform structure, and assist the facility integrity management personnel to make scientific decisions on abnormal conditions, which provides a good engineering practice for the monitoring, digitization and intelligence of the jacket structure in the future.
