| 摘 要： | 为应对"能效运营指标(EEOI)自愿应用导则",提出了在航行中采用调节纵倾的方法,降低营运能耗。选取了3100TEU集装箱船作为研究对象,应用Rankine源自由面势流理论计算不同纵倾下船舶兴波阻力系数以及总阻力系数,应用三维面元法计算了规则波中的波浪增阻,并针对实海域进行了増阻预报。研究表明,一定的艉倾能减小兴波阻力和总阻力。通过实海域増阻预报,服务航速下采用艉倾0.4°的纵倾航行会使波浪増阻增加4.21%,但总阻力仍能减少3.38%,较有效地降低了EEOI值。

| Abstract: | In order to cope the "Guidelines for voluntary use of Energy Efficiency Operational Indicators(EEOI)", a method with adjusting trim of a voyage has been attempted, which can reduce operational energy consumption. The wave resistance coefficient and total resistance coefficient of a 3100TEU container ship are investigated based on Rankine Source method, and wave added resistance in regular waves is investigated based on three-dimensional panel method, and the added resistance at actual sea is calculated. The results show that trim by stern will reduce the wave resistance and total resistance, while the wave added resistance in regular waves increases as well as the situation at actual sea. |
