Research on operation safety risk analysis of port power supply system based on improved LEC assessment method

Ports are important waterway hubs for China's economic and trade exchanges with other countries, which provide strong support for China's industrial and supply chains. The power supply system of the port is a significant guarantee for ensuring the normal production and operation of the port. In order to ensure the safe and stable operation of power supply system in the port, the company regularly conducts special safety production supervision activities on its subordinate power supply system in the port. In order to prevent safety accidents, an improved LEC method is adopted to establish a safety risk assessment system for the operation of port power supply systems. The paper takes the safety hazards discovered during the investigation of a certain port under the company as an example. The improved LEC risk assessment method is used to measure risk, calculate the risk value, classify and grade the risk. By risk assessment results risk prevention suggestions and measures are provided, which are used as a reference for the safe operation and management of company's port power supply system.
