30000m^3 LNG运输船能效设计指数研究

Research on EEDI Performance of the 30000 m^3 LNG Carrier

30 000 m^3 LNG运输船是上海船舶研究设计院(SDARI)自主研发的国内首艘小型LNG运输船。实船能效设计指数(EEDI)低于IMO基准值38.1%,达到授予CCS附加标志EEDI(III)的要求,具备了先进的能效性能。设计中采用了航速优化、载重量优化以及主机燃料选取了3种方法来降低该船的EEDI。研究了上述方法对LNG运输船的影响程度。

Independently developed by SDARI, the 30 000 m3 LNG carrier is the first domestic-made small scale vessel whose Energy Efficiency Design Index （EEDI） is 38.1% lower than IMO required level, satisfying the requests from CCS class notation EEDI （III）. EEDI was improved by various methods such as speed and deadweight optimization and fuel choice of main engine during design process. The influence of these methods on reducing EEDI of LNG carriers was analyzed.
