In response to the impact of 400，000 DWT large ore ships from Vale Brazil on China’s coastal port transportation market，the government issued relevant documents in 2015，clarified the current “Four Ports and Seven Berths” 400，000 DWT iron ore terminal layout plan，which effectively guided the terminals’ operations and berthing management. In the new era，with the increasing capacity of 400，000 DWT ships on the route from Brazil to China and the further adjustment of the domestic coastal iron and steel industry structure，it is urgent to study the adjustment of the 400，000 DWT ore ship unloading port plan. This article summarizes the terminal construction and operation of the original layout plan，analyzes the trend of future shipping market changes，and proposes that based on the systematic analysis of port resource conditions and the actual situation of planning and construction，we shall take regional foreign trade iron ore unloading needs into account to encrypt Shandong’s coastal layout reasonably and fill the gaps in the southern layout，and finally form a new layout plan for 400，000 DWT ore terminals in coastal ports to meet the urgent needs of the national steel industry layout and regional transportation.
