Wind-assisted propulsion
Wind-assisted propulsion on ships can be an effective way to reduce fuel consumption and emissions. Numerous methods are available, including Flettner rotors – tall, rotating cylinders mounted on a ship’s deck – and ventifoils, which are fixed airfoil-shaped propulsion units
C-Job provides independent advice on wind-assisted propulsion and has practical experience of its implementation. For example, we developed a 5,000 DWT cargo ship concept design with four Flettner rotors. This saves up to 18% fuel on average compared to similar, conventional cargo vessels. A wide array of factors create an optimized design, including size of rotors (versus cost), vessel size, sailing speed, route, and deck space.
C-Job has also developed a performance prediction program to both calculate fuel savings for a proposed vessel, and optimize wind-assisted propulsion in existing, new build ships or retrofit vessels. This is an excellent tool for shipowners who want to calculate fuels savings, and even optimize sailing routes.
