海上航线风能资源的调查与分析

Investigation and Analysis of Wind Energy Resources on Global Ocean Shipping Lines

根据英国水文局发布的2016年海图资料,整理出2016年全球9条典型航线上不同风力、不同风向的概率数据。分析这些数据,获得各往返航线4级以上可用风天数、5级以上强风顺风天数,发现香港→新加坡的南海航线、科伦坡→新加坡的马六甲海峡孟加拉湾航线、亚丁湾→科伦坡的印度洋阿拉伯海航线、上海→香港的东海航线、毕晓普岩→努瓦迪布的北大西洋航线和横滨→洛杉矶的北太平洋航线都有较好的风能资源,特别是后3条航线的风能资源最丰富,是未来运用风帆助航技术的最佳航线。对有效助推强风的顺风天数和风能资源的有效性进行分析,提出风能资源的强度指数、综合风能资源强度指数和综合有效强度指数,用来衡量海上航线风能资源的综合强度和有效性,可作为未来风帆助航船舶航线优化的重要选择指标。

According to 2016 routing chart published by the United Kingdom Hydrographic Office,the probability data of different wind scale and different wind direction on 9 typical global ocean shipping lines are collected. Available days with4 and 5 wind scales are accounted,which discovers that east sea line from Shanghai to Hong Kong,southern sea line from Hong Kong to Singapore,Malacca Strait line from Colombo to Singapore,Arabian Sea line from Gulf of Aden to Kuala Lumpur,North Atlantic Ocean line from Bishop rock to Nouadhibou,North Pacific Ocean line from Yokohama to Los Angeles have rich wind energy resources,especially the North Pacific Ocean line from Yokohama to Los Angeles,east sea line from Shanghai to Hong Kong and North Atlantic Ocean line from Bishop rock to Nouadhibou. Some new concepts are proposed and analyzed including intensity index,comprehensive intensity index and effective comprehensive intensity index,which are useful for ocean shipping line optimization of sail-assisted ships.
