24000 TEU级超大型集装箱船快速性优化设计

Hull Line Design and Hydrodynamic Performance Optimization of 24000 TEU Container Vessel

为克服船舶主尺度增大给船舶快速性带来的不利影响,同时兼顾船舶在不同航速下的快速性表现,以某24000 TEU级超大型集装箱船的设计建造项目为例,分别从船型主尺度选取、船型系数确定、初步线型设计开发及阻力优化和推进效率优化等4个方面详细介绍其基于船体线型的快速性优化设计过程。为该船设置桨前节能装置,并对其进行纵倾优化试验,进一步优化该船的快速性技术指标,减少其在实船营运过程中的燃油消耗。船模试验结果表明,该船型的快速性表现良好,能使航速达到22.7 kn,超出设计预期0.2 kn。

The main dimensions,preliminary hull line design,resistance optimization and propulsion efficiency optimization of a 24000 TEU container vessel are introduced.Energy saving device and the trim optimization are applied to improve the hydrodynamic performance as well as the fuel consumption.The speed predicted by model test reaches 22.7 kn,which is 0.2 kn higher than the design target.
