After China's accession to the WTO and the cross-strait \more severe challenges. Thus, in a short period of time, and comprehensively improve the problem the LPG ship's professional management level technical force and the crew became imminent. Undoubtedly, the crew simulator training is one of the more effective ways. In this regard, the United States, the United Kingdom has developed products and applications in many countries and regions. However, so far, although the domestic ship simulator also done a lot of work, but in simulation training for liquefied gas tanker, in addition to the Guangzhou Maritime Group training center in April 2001 and the British ship signed type LCHS2000 liquid cargo handling simulator (set simulator, including oil tankers, liquefied gas carriers and chemical tankers) orders, not yet appear in other types of liquefied gas ship simulator. Full-cooled LPG ship in the development of our country only a few years of history in this period, resulting in many problems. The overall quality of the liquefied crew is an important reason, accordance with \Based on the above-mentioned requirements, combined with Shanghai the College Youth Science Fund project, the use of computer simulation technology, the development of a liquefied gas ship simulator for crew simulator simulation training. In the course of the study of the subject, mainly focused on the operational requirements and taking into account other aspects, and strive to LPG Vessel operating characteristics and the actual operating requirements and to establish the simulation model to study development in line with the actual requirements of the liquefied gas the ship system simulation training training software. System testing, the system is running stable, accurate simulation effects have to achieve the purpose of the software development. The successful development of the project the Maritime Education to improve the level of teaching and improve the abilities of students and operating skills, have important practical significance, while helping China's shipping enterprises existing crew training and updating of knowledge. In this article, the author first introduces the overview of the development of liquefied gas carriers at home and abroad, the status and application of ship simulation as well as a brief introduction of liquefied petroleum gas and liquefied petroleum gas ship; liquefied gas tanker core device - reliquefaction installed type of stomach and role briefly described; Secondly, the typical cascade reliquefier effective analysis will certainly help to improve the performance of the device. - Compressors, heat exchangers, expansion valve more detailed performance analysis and mathematical modeling, and the cargo tanks to do a more detailed numerical simulation to calculate the heat load from the main part of reliquefaction loaded stomach The international gas company (LGI) Select the the corresponding reliquefier. Finally, this paper, the basic operation of the liquefied gas carriers - inerting, purging, pre-cooling, for loading cargo sailing, unloading VB PHOTOSHOP physical simulation to simulate the effect of comparison were satisfactory. By the level and experience of the limit, it is inevitable there will be omissions, please feel free.
