As an important guarantee for the natural gas supply in northern China,Caofeidian LNG receiving station has an average of 8~11 LNG ships arriving in port during the winter peak period,which will become the world’s largest LNG receiving station according to the planned expansion.Due to the strict supervision of the LNG ships’ navigation,the increasing number of ships arriving in port will exert significant pressure on the navigation efficiency.It’s necessary to demonstrate the adaptability and construction scale of the terminal and channel.Based on the multi-agent simulation modeling method,the whole process of LNG ship entering and leaving the Caofeidian Port is simulated numerically.The impact of LNG berths on the navigation efficiency of the channel is also evaluated quantitatively under the special channel conditions.The results show that when the number of LNG berths reaches four,the entry and exit of the ship are restricted obviously.The efficiency of the entry and exit of LNG ships can be effectively improved after optimizing the route.
