摘要
近年来,船东对船舶在实际运营的真实海洋环境中的航行性能越发关注。目前,船舶设计主要基于静水中性能开展优化,与实际海况具有一定的差异。本文针对船舶风浪中的快速性影响因素开展研究,以系列油船、散货船和集装箱为研究对象,采用二维切片法计算在典型海况BF6和BF8下的波浪增阻,并采用图谱法对螺旋桨进行重新设计,研究船舶主参数及螺旋桨轻转裕度对风浪中船舶性能的影响。结果表明:主参数对于油船和散货船的波浪增阻影响较大,对集装箱船影响较小,因此在船舶风浪中性能优化时需要根据船型分别考虑;此外,随着螺旋桨轻转裕度的增加,船舶静水和风浪中的推进效率降低,船舶在恶劣海况下低速航行所需的收到功率越低,船舶功率的预留空间更加充足。
In recent years,shipowners have become increasingly concerned about the actual performance in the real marine environment.At present,ship design optimization is mainly conducted based on performance in still water which has a certain difference from real-sea performance.The factors influencing the powering performance of ships in wind and waves were investigated taking series oil tankers,bulk carriers,and container ships as the research subjects.The theory of two-dimensional strip was used to calculate the added resistance under typical sea states BF6 and BF8.The propeller was redesigned using graph method to research the influence of light running margin in the wind and waves.The results show that the principal dimensions have a significant impact on the added resistance of oil tankers and bulk carriers,and have a relatively small impact on container ships.Therefore,it is necessary to consider the ship type separately when optimizing the powering performance in wind and waves.In addition,with the increase of the light running margin,the reserved space for power becomes increasingly sufficient.
