| 摘 要： | 分别从成套推进系统的技术可行性、投资成本、运营成本（包括燃料与维修）等角度对17万m3LNG船DFDE配置进行对比分析，寻找最经济的DFDE组合配置方案，即采用3×12V50DF＋1×6L50DF方案，该方案在不同工况下LNG自然蒸发量均能满足船舶运营要求，有效减少了船舶运营成本及维修成本，相比其他方案也最经济。

| Abstract: | The DFDE propulsion system configuration for 170 000 m3 LNG carrier was analyzed from the views of technical possibility, investment, operation cost including maintenance cost, so as to find the most economic DFDE configuration. When the configuration of 3× 12V5ODF ＋ 1 ×6LSODF was adopted, the BOG could meet the fuel gas consumption at the different con- dition and reduce the fuel cost, and also the configuration＇maintenance cost will be minimum. |
