大型LNG船推进型式研究

Study on propulsion type for large LNG carrier

介绍了大型LNG船船型的特点,对适合于大型LNG船的推进型式进行了分析研究和模型试验研究,对用于LNG船舶的不同类型的推进装置进行了比较分析。得出了一些结论,并指出在当前低排放绿色船舶的要求下,采用双燃料电力推进方式更有发展前景,但若要在大型LNG船上采用此推进方式,尚有待一些问题的解决。

The characteristic of large LNG carrier is introduced in this paper,and the propulsion types suitable for the LNG carrier are studied through analyses and model tests.With the comparison analyses of various propulsion equipments,some conclusions are obtained,and the duel-fuel electric propulsion is proposed under the low-emission green ship requirement nowadays,finally,the problems remain to be solved provided this propulsion type apply to the large LNG carrier are also discussed.
