Research On LPG Ship Liquid Cargo Operating System Simulation Of Full Pressure

Based on the general process of mathematical simulation, the paper makes simulation research on Yangzhou shipyard, in domestic3600m3LPG ship’s liquid cargo-handling system. Main contents are summed as follow:First, research and analysis the constitute and principle of Yangzhou shipyard, in domestic3600m3LPG ship’s liquid cargo handling system and related system. Second, hold the mathematical model of The full pressure LPG ship’s liquid cargo handling system, including liquid pump, cargo pipe valves, cargo tank, do hydraulic analysis and hold the mathematical model of the liquid cargo pipe network, and also hold the mathematical model of hydraulic power system, Inert gas system, tank washing system, ballast system, and ship floating condition. Third, Build simulation process of each device, institution and monitoring alarm of the liquid cargo handling system equipment, and based on the simulation process to create the framework for the development of application software. At last, by the modern software design method. In the IDE of Visual Studio2010, develop the simulation software’s interface and control program, construction and Realization of each function module of the system, complete the automatic simulation of LPG ship liquid cargo handling system, Finally, verify the feasibility of the simulation software, ensure that the real-time simulation software has precise data, accurate reaction, reliable function.The software automatically collects all relevant parameters, such as level, pressure, flow, etc. After the analysis and judgment, it provides data transmission, real-time display and fault alarm. All these actions can effectively guide the operation. It is a further attempt for automation and intelligent, and it can provide a theoretical basis for further study combined with multi-direction. The development of LPG ship’s Cargo-Handling Simulator is an important part of marine simulator for various vessel type, and it will help achieve pedigree and intelligent of marine training equipment.
