Analysis And Study On Transit Capacity Of Heshang Island Channel

The CPC Central Committee and the State Council to pay special attention to the important period of strategic opportunities, decided to implement the strategy of rejuvenating northeast old industrial zone, put forward the construction of Dalian as the significant shipping center in northeast Asia. But as the only channel of ship in and out of the port area of Dalian bay, the width of Heshang Island Channel is only150meters, and one-way navigation, as the ship to port volume increased year by year, the Heshang Island Channel traffic density will increase gradually.Based on the overall plan of constructing Dalian Port, Heshang Island Area is supposed to be built into channel ro-ro transport system together with coal shipping transport system, making an integral part of modern service system of Dalian Port.In order to tackle the problem mentioned above, this article provided systematic analyses on related channel designing, grounded on the overall plan of Heshang Island Channel, the relationship of ship traffic and channel capacity, combined with the prediction of ship traffic. In addition, this paper conducted a feasibility study on two-way navigation within the width of240m.After analyzing both natural surroundings and traffic conditions of Heshang Island along with the areas nearby, the writer mainly focused on the regulation of traffic flow and particular problems in the process of operation. Subsequently, this article applied the conclusions of simulation data and offered a certain solutions on widening Heshang Island Channel followed by realizing two-way navigation.The solutions in this article, on the one hand, could effectively decrease the traffic density within current natural surroundings and channel capacity; moreover, the safety of navigation could be largely improved through scientific and rational planning. On the other, to ensure coal and ro-ro berthing on a regular track as well as to further explore the operating potential of Heshang Island Channel, it also shows great practical values by boosting the steps on the construction of Northeast Asia’s shipping center.
