Influence Of Newly Construction Of LNG Wharfs On The Operation Of Bulk Berths Under The Restriction Of Fairway

Liquefied natural gas is a kind of energy whose environmental position and economic value is of great significance. On the other hand, it can be rather hazardous. During the process of wharfs’ operation, it should be taken into consideration to offer the safety of LNG terminals’operation and LNG tankers’ navigation, adequate navigation security assurance and emergency disposal plans, all of which make the conflict between LNG wharfs and other berths fiercer in sharing public resources. Besides, as costal resource in China is very limited, many LNG terminals have to share the same harbour with some other types of berths, and usually LNG tankers have to share the public fairway with other ships. LNG tankers have to navigate under forced control, which may block the fairway from other ships using it. And this negative influence on double-way (bi-way) fairway is more significant than that on single-way fairway. If travel along long artificial fairway, ships will spend more time navigating, making the negative influence much more outstanding. All reasons listed above have inevtitably worsened the environment of using public resources. So it is necessary to research the influence of LNG berths’construction and LNG tankers’ navigation under the restriction of fairway.A simulation model is established basing on the system simulation method and multi-agent theory, in which the navigation of LNG tankers is taken into account. In this model, the restriction of fairway and different numbers of bulk berths are considered. By taking berth occupancy and berth’s capacity as indicators, the influence that LNG wharfs and LNG tankers have on the operation of other berths is analyzed.Basing on the simulation model of Huanghua Port, study the influenceon the throughput of bulk cargo and the average time ship staying at berth, when the throughput of LNG tankers increases from 0 to a certain value (positive), under the restriction of long artificial fairway. Finally, analyze the results and give an acceptable explanation. The results will provide guidance on the planning and construction of LNG terminals in the future.
