Taking the second phase of the proposed Hubei Jingzhou coal,iron and water intermodal transportation storage and distribution base as an example,this paper studies the dock ship berthing and unberthing water in view of the most unfavorable situation when the navigation rules of “respective left” are implemented and the wharf is arranged on the left bank of the bridge.Combined with the analysis of the relevant results of the ship docking berthing route setting and ship maneuvering simulation test,the distance between the dock and the bridge should not be less than 4 times the length of the designed ship type of wharf and the minimum distance between the lowest end of the wharf and the water area of the bridge area should not be less than 1 time of the length of the ship type,so that the ships in the proposed project can meet the requirements of crossing the river and berthing outside the water area of the bridge.When leaving the berth,the ship needs to make two cross-sail turns to meet the requirements of the specification.However,from the perspective of navigation safety,the risk of ship navigation safety is smaller when turning around in place.Therefore,it is suggested that the river section of the bridge area be modified in the next revision of Inland River Navigation Standard to be consistent with the waters of the bridge area.
