ABSTRACT

The current research deals with the possibility of relying on wind energy, specifically Flettner rotors; as a source of ships propulsion to reduce ships’ emissions. The paper highlights the technical, environmental, and economic aspects of wind-assisted propulsion systems. As a case study, four Flettner turbines are examined to be used onboard a bulk carrier ship, considering three different routes. Technically, the ship’s route and wind characteristics are the focal aspects that affect the output power of Flettner rotors. The economic results indicate that the payback periods for the selected Flettner rotors will be 7, 13, and 11 working years for the first, second, and third ship routes, respectively, with considerable levelised costs of energy. Environmentally, NO_x and CO₂ emissions will be decreased by 154.3 and 5089 ton per year, for longest route, with cost-effectiveness of 3350 and 89 $ per ton, respectively with a 10 percent interest rate.

摘要

目前的研究涉及依赖风能的可能性，特别是 Flettner 转子；作为船舶推进的来源，以减少船舶排放。本文重点介绍了风力辅助推进系统的技术、环境和经济方面。作为一个案例研究，考虑到三种不同的路线，对四台 Flettner 涡轮机进行检查以在散货船上使用。从技术上讲，船舶的航线和风力特性是影响 Flettner 转子输出功率的重点方面。经济结果表明，选定的 Flettner 转子在第一、第二和第三条航线的投资回收期分别为 7、13 和 11 个工作年，能源成本相当高。环境方面，NO _x和 CO ₂最长路线每年减排 154.3 吨和 5089 吨，成本效益分别为每吨 3350 美元和 89 美元，利率为 10%。
