ABSTRACT

A 4 degrees of freedom ship performance prediction model is used to compare wind-assisted ship propulsion technologies: the Flettner rotor, a wingsail and the DynaRig concept. An Aframax Oil Tanker on a route between Gabon and Canada is used in a case study to compare the three technologies using actual information for the voyage. The fuel savings for were calculated and they varied between 5.6% and 8.9%; the Flettner rotor showed the largest fuel savings. A parametric study of the Flettner rotor technology was carried out to research how its dimensions and operation conditions for two ship types on two voyages influence the fuel savings. The results show that fuel savings were achieved by several percentages. It is shown that it is necessary to select and operate the Flettner rotor according to its ship type, speed, voyage routes and corresponding weather conditions to achieve as large fuel savings as possible.

三种风力辅助船舶推进技术的船舶能源性能研究,包括弗莱特纳转子技术的参数研究

摘要

使用4个自由度的船舶性能预测模型来比较风助船舶推进技术:Flettner旋翼,机翼和DynaRig概念。在案例研究中,使用了一条加蓬和加拿大之间航线上的Aframax油轮,以使用航程的实际信息来比较这三种技术。计算出的燃油节省量在5.6%和8.9%之间变化;Flettner转子显示出最大的燃油节省。对Flettner旋翼技术进行了参数研究,以研究其在两次航行中的两种船型的尺寸和运行条件如何影响燃料节省。结果表明,燃油节省率达到了几个百分点。结果表明,有必要根据舰船的型号,速度,
