As China 's rapid economic growth , the need to consume a large amount of basic energy , such as oil , coal , and our own energy can not meet the increasing demand , more and more dependent on imports . LNG as a clean, efficient new energy to get constant attention , the surge in oil prices and instability in the oil trade , but also further promote the energy demand of LNG . LNG Energy has always been our country there is a big gap , in order to meet this huge gap also for energy security strategy , China in recent years began a nationwide planning and construction of a large number of LNG terminals , and began to import large quantities of LNG chapter. Dalian LNG import project is one of many projects , mainly to meet the northeastern part of LNG supply , is now in the construction period . Firstly, combined with international LNG market environment and the actual situation of our country LNG market , supply and demand situation and the international LNG trade patterns and LNG shipping market conditions were analyzed to determine the main issues which the research environment . Second, imports for Dalian LNG project specific analysis to study the basic situation of the project , supply and demand characteristics and route characteristics . Finally, the main part of this paper, namely transportation security plan for the project study , the first to determine the qualitative transport security options , then use the model to determine specific programs. LNG transportation is rather special, have a dedicated LNG carriers , routes fixed , in determining its transportation options, combined shipping arrangement theory, for planning transportation security programs . Articles in determining the Dalian LNG project imports transportation security programs , the use of mathematical models to determine the ship's hull form optimization method , the purchase or charter transportation solutions specific issues. Number of vessels of the ship must take the integer is consistent with practical significance, so using integer programming model to solve this problem. On the assumption that certain conditions , based on the objective function is considered when building ship fleet investment and establish the minimum annual cost of operating the applicable model , depending on the project limits established constraints. By collecting, calculating get a lot of data, the application lingo 9.0 solve the model , draw numbers and two transport vessels for proper traffic routes and minimal costs.
