In order to systematically study the design method of the control system of a floating LNG terminal project in Pakistan,we focus on the special requirements of mooring,berthing,and operation for floating LNG terminals,draw the suitable control system framework,and introduce the relationship and configuration of subsystems including ship-shore linkage system,fire control system and auxiliary berthing system. Based on the layout condition of a floating LNG terminal in Pakistan,we study the relevant provisions of national standards and combine them with the current domestic control system design standard,and summarize an idea and solution for a control system different from normal LNG terminals. The results show that compared with control system establishment for normal LNG terminal,there are further optimizations space in data transmission,reasonable cable arrangement,and control object selection for floating LNG terminal.
