LNG船电力推进船型的方案决策

On plan of electric-propulsion LNG ship

由于无法利用LNG船液货舱内自然蒸发的天然气,传统的采用柴油发电机组作为中心电站的电力推进技术一直无法在大型LNG船上使用。但是随着双燃料发动机的出现,这种局面开始发生变化。对预研中的大型LNG船采用双燃料电力推进技术进行了技术、经济性分析,论证了双燃料电力系统的可行性及电力推进系统的配置情况,以探讨LNG船电力推进船型的特点。

The traditional electric propulsion which take the diesel engine generators as power plant can not be used on large LNG carrier,because of the incapable of utilizing the gas boil-off in liquid cargo tank.However,the development of dual fuel engine changes this situation now.This paper analyses the technology and economy of dual fuel electric propulsion,proves the possibility and configuration of the system,and discusses the characteristic of LNG carrier with electric propulsion system.
