Shipping faces challenges of reducing the dependence on fossil fuels to align with the international regulations of ship emissions reduction. The maritime industry is in urgent need of searching about alternative energy sources for ships. This paper highlights the applicability of harnessing wind power for ships. Flettner rotors as a clean propulsion technology for commercial ships are introduced. As a case study, one of the bulk carrier ships operating between Damietta port in Egypt and Dunkirk port in France has been investigated. The results showed the high influence of the interaction between ship course and wind speed and direction on the net output power of Flettner rotors. The average net output power for each rotor will be 384 kW/h. Economically, the results reveal that the use of Flettner rotors will contribute to considerable savings, up to 22.28% of the annual ship's fuel consumption. The pay-back period of the proposed concept will be 6 years with a considerable value of levelized cost of energy. Environmentally, NO and CO emissions will be reduced by 270.4 and 9272 ton/year with cost-effectiveness of $1912 and $55.8/ton, respectively, at annual interest rate of 10%.
航运业面临着减少对化石燃料的依赖以符合船舶减排国际法规的挑战。海运业迫切需要寻找船舶的替代能源。本文重点介绍了船舶利用风能的适用性。介绍了作为商用船舶清洁推进技术的弗莱特纳转子。作为一个案例研究，对一艘在埃及达米埃塔港和法国敦刻尔克港之间运营的散货船进行了调查。结果表明，船舶航向与风速及风向之间的相互作用对弗莱特纳转子的净输出功率有很大影响。每个转子的平均净输出功率将为384千瓦/小时。在经济方面，结果显示使用弗莱特纳转子将有助于大幅节省成本，高达船舶年燃料消耗的22.28%。所提出概念的投资回收期将为6年，能源平准化成本具有相当大的价值。在环境方面，在年利率为10%的情况下，每年的氮氧化物和一氧化碳排放量将分别减少270.4吨和9272吨，成本效益分别为1912美元和55.8美元/吨。
