Development of Main Boiler Simulation System for LNG Ship

It is significant to train skilled marine engineers for LNG ship through the marine engine room simulator. Main boiler simulation system of Liquefied natural gas (LNG) ship is an important part of marine engine room simulator. Through the analysis of mechanism, using the method of modular modeling and lumped parameters modeling, a non-linear real-time modularized mathematical model for a LNG ship boiler has been developed based on the principle of fluid dynamics, heat transfer and thermo-dynamics. Simulation studies were conducted and the results show that the built model has satisfied precision and dynamic characteristics and the accuracy meets the simulation requirements. Also the main boiler simulation system has been developed in marine engine room simulator system. The software programming and interfaces of the simulation system have been designed and its main functions and applications have been introduced.
