舟山北部水域大型泊位规划对通航效率影响的仿真模拟研究

远期规划的舟山北部水域大型泊位高达50余个。进港航速低、历时长、乘潮和靠泊时间窗口要求特殊,是大型船舶影响港口通航效率的主要因素。在现状及近、远期港口规划条件下,基于Arena仿真建模方法,构建舟山北部水域大型船舶进出港仿真模型,定量统计分析不同阶段大型泊位规划对船舶通航效率的影响。结果表明:近、远期规划实施后大型船舶流量增加33%和65%,远期规划中黄泽作业区的船舶平均等待时间较现状增加约10.5 h,小洋山作业区和鼠浪湖作业区分别增加约0.5 h和2 h,对通航效率整体影响有限。

Simulation study on impact of large berth planning on navigation efficiency in northern Zhoushan waters

There are more than 50 large-scale berths planned in the long-term of the northern waters of Zhoushan. The low port entry speed,long duration,specific tide,and berthing time windows are the key factors impacting the port navigation efficiency of large ships. Under the conditions of existing and short-term and long-term planned ports,based on the Arena simulation modeling method,a simulation model of large ships in and out of the port in the northern Zhoushan waters is constructed to quantitatively analyze the impact of large-scale berth planning at different stages on the navigation efficiency of ships. The results show that after the short-term and long-term planning,the flow of large ships will increase by 33% and 65%,and the average waiting time of ships in the Huangze operation area will increase by about 10. 5 hours compared with the current situation and that in the Xiaoyangshan operation area and the Molanghu operation area will increase by about 0. 5 h and 2 h respectively,which has a limited impact on the overall navigation efficiency.
