Under the “dual carbon” goals,shore power utilization by ships at berth has become a key measure to advance the green and low-carbon transformation of Yangtze River shipping.However,research on safety risk control technologies for shore power equipment and facilities remains relatively scarce.To address the challenge of ensuring the safe and stable operation of unattended anchorage shore power systems under large water level fluctuations,nine risk factors affecting the operational safety of such systems are analyzed through a combination of literature review and expert interviews.A safety risk analysis model based on the DEMATEL-ISM model is established,which identifies the reliability of intelligent perception information as the core influencing factor,shore power equipment damage and network security as critical transmission factors,the external environment as the underlying factor,and management and maintenance vulnerabilities as the superficial factors.On this basis,multi-dimensional safety control technologies covering multi-source information fusion,equipment fault diagnosis,secure communication,environmental monitoring and system operation and maintenance are proposed,providing an effective solution for the safe and stable operation of such systems.This has positive significance for promoting the unmanned and intelligent development of shore power facilities.
