摘要
双燃料电力推进系统在LNG运输船上的应用越来越普遍。由于采用了清洁能源天然气作为船舶的动力燃料,使污染物排放情况明显好于传统船舶,能效也更高,但国际海事组织现有能效设计指数(EEDI)计算未能覆盖此类型船舶。通过一型实船计算,探讨了采用双燃料电力推进系统船舶的能效设计指数评估方法。
Dual-fuel-diesel-electric propulsion system was more and more popular in modem LNG carriers. LING was a much cleaner energy source comparing with the traditional heavy fuel oil As a result,the emission and energy efficiency of the ships driven by DFDE was better than conventional existing ships. However, IMO＇ s EEDI calculation guideline didn＇t cover such kind of vessel. The paper gave a way to evaluate the EEDI for DFDE vessel,together with an example.
