摘要论文对天然气运输中的LNG运输和NGH运输方式的成本问题展开详细分析,讨论了运输过程中的设备成本、运输船成本和再气化成本三个重要组成,计算分析得到关于两种运输方式的成本表达式,并基于此,对影响因素中的航速、船舶租赁价格、单船运输量等进行敏感性分析。研究发现,LNG与NGH运输方式受到运输距离的影响,存在较优运输方式;同时,随着影响因素的变化,运费计算结果将受到不同程度的影响。

Cost of LNG transportation and NGH transportation in natural gas is analyzed in this article.Three important components i.e.equipment costs,transportation costs and regasification costs in the transportation process are discussed.Cost expressions for LNG transportation and NGH transportation are presented respectively,based on which a sensitivity analysis of influence factors such as the speed,the rental price of the vessel and amount of traffic on a single vessel is performed.It is found that either LNG or NGH transportation modes are affected by the transport distance,and there is better transport mode,but the influence factors will affect the freight.
