摘要
曹妃甸LNG接收站作为我国北方天然气供应的重要保障主体,冬季高峰期月到港LNG船舶达到8~11艘,按照规划扩建后将成为国内外规模最大的LNG接收站。由于LNG船舶通航的严格监管,到港船舶数量的增加会对航道通航效率造成显著压力,因此需要论证码头建设规模与航道的适应性。在现状定线制通航条件下,基于多智能体仿真建模方法,构建曹妃甸港区LNG船舶进出港全过程仿真模型,定量评估不同LNG码头建设规模对LNG船舶通航效率的影响。结果表明,当LNG泊位数达到4个时,船舶进出港受制约明显,优化航路后能有效提高LNG船舶的通航效率。
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.
