Abstract: LNG receiving terminal is characterized for its complicated process and sensitivity to the external environmental changes. Thanks to its difficult operation and management, the simulation and training software is usually adopted as calculation tools for personnel training and formulation of operational plan. Therefore, the LNG receiving terminal simulation and training software V1.0 is independently developed, which is based on process flow simulation and integrated with control logic and chain protection system simulation. It adopts a distributed network structure and systematically and comprehensively displays a series of functions, such as actual terminal process flow, operation of equipment, control logic, optimized operation and operational training. The structural design is unique for its integration, network and modules, satisfying the demand for large-scale training by big receiving terminals. The software has been basically industrialized at home and reached the advanced domestic technological level, gradually replacing the imported foreign products.
