The traditional automated container terminal yard is arranged vertically，and high-speed rail-mounted gantry（RMG）cranes are used to horizontally transport containers by symmetrical relays in the yard. In the process，some problems stand out，such as high energy consumption and concentrated and limited interaction points of loading and unloading at the ends. This paper fully studies the current situation and adaptability of the layout of automated container terminals both at home and abroad. Considering the production and operation characteristics and requirements of the automated container terminal in Qinzhou Port，we explore a suitable layout of automated container terminals for Qinzhou Port upon massive research and analysis and put forward an overall design of a “U-shaped vertical layout” for the yard. Supported by simulation data，this design can provide a new model for the determination of the layout of automated container terminals.
