摘要 船舶能效指数(EEDI)的强制实施使得设计的船舶主机功率有一定程度上的降低。以阿芙拉级油船为例,评述几种波浪增阻计算方法以及其精度,并进一步开展第二层方法的评估。分析波浪增阻计算精度对最小推进功率评估的影响,为新船型的最小推进功率验证提供参考。 As the energy efficiency design index(EEDI)being implemented,installed propulsion power of ship is designed to be much lower than ever before.For the method of simplified assessment,the calculation of added resistance due to waves is very important.In the present paper,in order to discuss the effect of various numerical methods on the evaluation of min propulsion power,calculation methods of added resistance for an Aframax tanker were first investigated and the accuracy was compared.Based on computation results,the level 2 assessment was further performed.Through these researches,data and experience for validity were established,which could be referenced to design undertaking in the future.
