Three super-large container berths with a capacity of 200,000-ton each are planned to be built in the eastern operation area of Yantian Port.To address the technical challenges caused by the long hull,high safety requirements for mooring,and significant wind and wave impacts on the southern berths,which complicate the layout of the dock,an analysis based on the surplus length between berths and the effects of wind and waves has been conducted.This analysis proposes reasonable optimization measures for the dock layout.Firstly,in accordance with regulatory requirements,mooring needs of shipping companies,and port operational conditions,it is suggested that the surplus length between berths be set at 90 meters,ensuring safety and feasibility through mooring simulation calculations;Secondly,regarding the issue of unreclamed area in the southeast corner of the port,an analysis of the mooring stability conditions under single and combined wind and wave scenarios for the southern berths has been conducted.It has been clarified that adopting a full-coverage layout can significantly increase the number of berths operation days.This article effectively resolves the safe mooring issues for super-large container ships and provides scientific basis for the necessity of land reclamation in the southeast corner of the port area,meeting the requirements of mooring safety and stability.
