摘　　要：随着EEDI第3阶段实施日期迫近,对于采用常规推进方式的油船和散货船,必须借助第二层评估方法进行主机最小功率评估,“MEPC76导则”从法规层面正式确定了最小推进功率的第二层评估方法。本文针对船舶设计中,由于螺旋桨设计相对滞后可能带来最小推进功率评估不满足要求的风险,分析了影响最小推进功率评估结果的主要因素,对不同设计参数的螺旋桨进行最小推进功率评估并对比分析,通过计算分析,可知螺旋桨的设计参数,如螺距比、直径、盘面比、桨叶数以及主机额定转速功率,均会对最小推进功率评估结果产生一定的影响,通过本文研究,可为相关船型的设计开发以及螺旋桨设计满足最小推进功率评估要求提供一定的参考。As the effective date of EEDI phase 3 approaching,for oil tankers and bulk carriers with conventional propulsion system,the minimum propulsion power must be evaluated by assessment level 2.The“MEPC76 guideline”es-tablished the valid minimum power assessment method from rule's respect.As the propeller which is designed always later than the ship will cause some risks that the minimum power assessment can't be complied with,this paper analyzed the main factors that will have influence on the minimum power assessment and provided the comparison for the results from pro-pellers with different parameters,in order to provide some reference for ship and propeller design to comply with the minim-um power requirement.
