天津港大港港区LNG双泊位联合运行通航管理方案

Management plan for joint operation of LNG double berths in Tianjin Port area

为满足北方地区冬季LNG高峰期保供目标,部分渤海沿海港口在同一港池内规划布置双LNG泊位。鉴于双泊位联合运营下的LNG船舶关联性强且操纵难度高的特点,有必要对LNG双泊位联合运行进行调度管理方案研究。以国内首座正式投产运营的LNG双泊位为例,基于船舶操纵模拟仿真方法,通过分析LNG船舶航行对航道通航效率影响及相邻泊位联动性,提出双泊位运营下的LNG船进出港优先级。在此基础上,结合LNG双泊位运营特点和通航管理规则,制定近期和远期不同阶段的船舶联合调度组织模式。研究结论可为单港池LNG双泊位的通航管理提供决策依据。

To meet the target of maintaining LNG supply during the winter peak period in northern China,two LNG berths are planned for the same harbor basin in Bohai Sea.In view of the complexity and relevance of LNG ships entering and departing ports under the joint operation of berth groups,it is necessary to study the joint operation and dispatching management of two LNG berths.Taking the first LNG double berth officially put into operation in China as an example,based on the ship maneuvering simulation method,this paper analyzes the influence of LNG ship navigation on the passage capacity of the waterway and the adaptability of adjacent berths,and puts forward the priority of LNG ships in and out of the port under the operation of double berths.On this basis,combined with the characteristics of LNG double berths operation and navigation management rules,the short-term and long-term ship joint dispatching organization model at different stages are formulated.The research results can provide decision-making basis for the navigation management of LNG double berths at a single port site.
