According to the latest industrial planning and overall layout of Zhoushan Green Petrochemical Base，we carry out the planning adjustment of the Yushan Port. Through analyzing the effect of the implementation of the Yushan Port planning，we carry out the analysis of the transport demand and the prediction of the design ship type，propose the scope and the key points of the planning adjustment，and summarize the principles of the planning adjustment. The principles concluded are as follows：according to the miniaturization characteristics of a chemical tanker，a rational arrangement of the berth is carried out；specialized container terminals can effectively provide loading and unloading and save coastline resources；the dock form reasonably can be arranged according to berth grade demonstration. The results show that the adjusted planning scheme can save the engineering investment，improve the loading and unloading efficiency，and save the resource of the port shoreline.
