Liquefied gas carrier cargo handling operations are critical to ship safety. In order to improve the quality and efficiency of cargo handling of liquefied gas carriers, the loading and unloading operation of the liquefied gas carrier was studied and a set of LPG remote cargo operation simulator with automatic bargaining function was designed. Introducing the components of the simulator: the console unit and the simulated cargo tank unit in brief, the design ideas and specific functions of the automatic barge and remote control of the core part of the system are introduced in detail. The simulator feasibility verification is carried out by comparing the error between the actual loading and unloading operation with the system simulation loading and unloading operation. The simulation training functions verification is carried out by testing people who use the simulator for training. The final results show that the error is within the acceptable range, and people who use the simulator for training can pass an authoritative comprehensive exam. It is shown that that the system can simulate the important operations in the cargo handling process and has an excellent training effect.
