Discharging part of LNG liquid cargo handling simulator

With the development of the national economy, it is important to develop LNG (Liquefied Natural Gas) liquid cargo handling simulator. In this paper, the discharging part of Liquid Cargo Handling Simulator of LNG Carriers is developed by Visual Basic. The system includes 5 major forms and 3 mathematical models such as cargo pump model, the pressure and temperature model of the LNG vapour in the cargo tank and the liquid level model. The system can complete the unloading task. The system has become a preliminary model of LNG liquid cargo handlings simulator training. © Maxwell Scientific Organization, 2013.
