Study On The Influence Of Harbor Inner Anchorage Scales To The Channel Transit Capacity For Coastal Container Port

In recent years,as the rapid development of China's economy and the large-scale ships in the world, China's port construction is also showing new features,the construction of large deep-water berths and specialized berths intensifying, the new features bringing economies of scale-effect but also bringing new challenges for port construction at the same time, These new features make the port land area service system, channel grade scale development and construction of navigation conditions improved. However, the domestic ports accelerate the pace of construction of deep-water berths and waterways, at the same time, resulting in channel capacity and other related issues, and which also restricts the healthy and rapid development of ports.How to satisfy the normal productions and vessel navigation operations of the port, while reducing energy consumption, saving costs and improving the channel transit capacity at the same time, which should be taken into account in the aspects of engineering design, construction, operations.Under the permission of the water area conditions,the paper propose build harbor inner anchorage to improve channel transit capacity, and created a simulation model of ship operating system with single-channel based on the inner anchorage in coastal container port. on the basis of considering the natural conditions, channel conditions and port service levels and other factors, obtained the relationship between the scale of harbor inner anchorage and the combination of anchorage berth when the travel time in fairway and depth of mooring water under certain condition, and then to determine the port water area of the mooring, and also obtained the relationship between the scale of harbor inner anchorage and channel transit capacity, the channel transit capacity with the increase of harbor inner anchorage capacity, but remains unchanged after a certain value.Finally analysis of channel transit capacity whether it has harbor inner anchorage to compare.
