中文摘要：

非碳能源利用和船舶减阻技术是船舶能效提升的有效方式，受船舶运营和非碳能源利用模式的影响，很难孤立地考虑非碳能源的利用效果，需要研究船舶非碳能源利用模式和能效提升的协同作用，在引入等效非碳能源概念的基础上，阐述了非碳能源利用与等效非碳能源利用模式，通过创建特征值及计算公式，定量分析了船舶非碳能源利用与船舶减阻技术之间的协同关系以及对船舶能效的影响，对新船能效指数设计和船舶能效管理具有指导意义。

英文摘要：

Non-carbon energy utilization and ship drag reduction technology are effective approaches to improve energy efficiency. However, limited by the operation of the ship and the use patterns of non-carbon energy; it is difficult to consider the isolated effect of carbon energy. There is a strong correlation between non-carbon energy utilization and energy efficiency improvement technical methods, where it is crucial to study their synergistic actions. Through proposing the concept of equivalent non-carbon energy, the synergistic effect of non-carbon energy utilization and the equivalent non-carbon energy utilization are described. By the establishment of eigenvalue and formulas, the quantitative analysis of the synergistic relationship between ship non-carbon energy and ship drag reduction is investigated as well as their influences on ship energy efficiency. It is believed that the knowledge gained in this study wiIl provide a guidance for the energy efficiency index design of new ship and ship energy management.
