【摘要】 选取我国沿海具有代表性的6条航线,对各航线上的风频分布进行了较为全面的统计分析,并给出了风频分布直方图,针对6条典型航线,选用800 t风帆助航船作为计算船型,对我国沿海推广风帆助航技术的经济效益作了全面的计算分析,得出了一些有参考价值的数据和结论。根据计算结果,我国沿海推广风帆助航技术其帆节能可达9.08％～15.68％,其中天津—大连及温州—上海两条航线节能效果尤为明显,分别达15.68％和14.01％,这说明在中国沿海风帆船具有广泛的推广应用前景。更多还原

【Abstract】 This paper statistically analyses the wind frequency distribution of six coastal lines chosen as the representives of china coastal lines and gives the histograms. Taking the 800 t sail -assist cargo ship as an example, Jhe authors estimates the economic benefits for developing the sail -assist technology and gets the useful conclusions and data. The results show that, the development of sail -assist technology can save fuel of 9. 08% to 15. 6%, especially on the routes of Tianjin-Dalian and Wenzhou-Shanghai. The energy conservation comes up to 15. 68% and 14. 01%. It shows a wide application future for developing sail -assist cargo ship on China coastal lines.更多还原
