摘　　要：文中以乌江航道为例,针对当前推广应用的千吨级绿色高能效标准船型,基于乌江标准船型的船模阻力与自航试验,测试了不同水深状态下阻力及自航性能参数.采用傅汝德换算法估算实船阻力及有效功率,分析各工况下有效功率与航速的对应规律,为标准船型选定合适的主机功率.结合船舶能源应用现状制定不同动力方案,计算并比较各方案对应的碳排放与必要运费率,最终推荐柴油-天然气双燃料动力模式.Taking Wujiang Waterway as an example,the resistance and self-propelled performance parameters in different water depths were tested based on the model resistance and self-propelled test of the thousand-ton green and energy-efficient standard ship type currently popularized and applied.The Froude transformation algorithm was used to estimate the resistance and effective power of the real ship,and the corresponding law between effective power and speed under various working conditions was analyzed to select the appropriate main engine power for the standard ship type.Based on the current situation of ship energy application,different power schemes were formulated,and the corresponding carbon emissions and necessary freight rates of each scheme were calculated and compared,and finally the diesel-natural gas dual-fuel power mode was recommended.
