The Sanya Nanshan Port Public Scientific Research Terminal is the first public scientific research terminal in China,and also the public scientific research mother port terminal.It is necessary to meet the needs of scientific research vessels and support vessels,as well as the functions of berthing,transshipment,material supply,scientific research testing,and maintenance,while also taking into account cargo loading and unloading,and reserving functions such as roll on and roll off for national defense readiness needs.The overall layout of the terminal is a key and difficult point in engineering design.This article focuses on the characteristics of public scientific research terminals and discusses the overall layout ideas and plan of the Sanya Nanshan Port Public Scientific Research Terminal project.The key points for the utilization and layout of the scientific research terminal shoreline,water area layout,land area layout,and slipway layout are obtained,fully reflecting the design concepts of advanced,efficient,energy-saving,environmental protection,economic and sustainable development,aiming to provide reference for similar projects.
