The invention discloses an integrated energy-saving propulsion design method for an ultra-large oil tanker, and relates to the technical field of ships, according to the method, after structural parameters of a tanker body are determined, optimization of bow linearity and stern linearity is carried out with the purpose of optimizing fast performance and energy-saving effect, and the bow linearity enabling the wave-making resistance coefficient to be minimum is designed; by optimizing and improving the linetype and combining the linetype with the hydrodynamic energy-saving device, the energy efficiency level of the ultra-large oil tanker obtained through design can be improved by 5% or above compared with the existing average level when conventional fuel is used, EEDI can be reduced by 30% or above at most compared with a base line, and the energy efficiency of the ultra-large oil tanker can be improved by 5% or above compared with that of an existing hydrodynamic energy-saving device. Therefore, the requirement of EEDI phase 3 is met.
本申请公开了一种超大型油船一体化节能推进设计方法,涉及船舶技术领域,该方法在确定船体结构参数后,以快速性能和节能效果最优为目标分别开展艏部线性和艉部线型的优化,设计使得兴波阻力系数最小的艏部线型,以及使得整船收到功率最低的横剖线呈反曲型结构的艉部线型,通过优化改进线型结合水动力节能装置,可以使得设计得到的超大型油船在使用常规燃料时的能效水平也能相较于现有平均水平提高5%以上,EEDI相比基线最多可降低30%以上,从而满足EEDI phase 3的要求。
