In view of the gap between the throughput capacity of domestic LNG terminal jetty and the advanced international level,the main factors affecting the handling capacity of domestic LNG terminal jetty are determined by analyzing the statistical data of a LNG terminal jetty,which are channel management constraints such as channel depth limit (tide ride) and night berthing limit,then four simulated working conditions are determined accordingly.The simulation software is used to simulate the ship’s entry and departure stages under different working conditions,and the capacity and waiting time under different berth utilization rates are obtained.Through the analysis of the simulation results,the paper points out the most influencing factors of domestic LNG terminals jetty throughput capacity,reasonable utilization rate of LNG terminals jetty,and throughput capacity of Q-Flex type and above LNG terminals,which can provide reference for the construction and management of LNG terminals jetty.
