“…With the globalization of the world economy, the seaborne trade grows steadily and accounts for 75% of the world merchandise trade. Following with the boom of the seaborne trade, the number, 1,2 the types, and the tonnage of the vessels are increased remarkably. 3 Due to the burning of heavy oil, the air pollution quantity generated by vessels is considerable.…”

Wind energy plays a significant role in the energy consumption reduction of the sail-assisted vessels. During the navigation process, how to select the ideal airfoil sails is crucial for the vessel safety and wind energy conversion efficiency. We resolve the airfoil sails selection problem by utilizing computational fluid dynamics simulation. Within the computational fluid dynamics simulation approach, with shear-stress transport k-v turbulence model, we analyze the performance of the three typical airfoil sails including NACA23012, NACA0012, and NACA0018 in the wind field from the perspective of force condition, lift and drag coefficients, and lift-drag ratio under generous wind speeds and angles of attack. And we investigate the pressure contours of the airfoil sails. Then, we can determine the aerodynamic performance of the airfoil sails promptly and identify suitable sails for the sail-assisted vessels under the given wind field.

“…[42] shows that the wind speed is higher in the Northern Hemisphere in the winter and enables Flettner-rotors to create larger fuel savings. In [7,62,67], the direction of the voyage is found to cause variances in fuel saving. The dominant west-east wind direction occurring in the Atlantic Ocean resulted in a significant difference in fuel savings between Baltimore to Wilhelmshaven (36%) and Wilhelmshaven to Baltimore (14%) [7].…”

“…In general, it is shown that with all other factors being identical, the higher the wind speed, the larger the energy output of the WASP technology, which results in higher fuel savings. This is not unexpected, as WASP technologies utilize wind power to produce thrust for ships [6,62,[64][65][66][67]69].…”

A Comeback of Wind Power in Shipping: An Economic and Operational Review on the Wind-Assisted Ship Propulsion Technology

et al. 2021

View full text Add to dashboard Cite

Wind-assisted ship propulsion (WASP) technology seems to be a promising solution toward accelerating the shipping industry’s decarbonization efforts as it uses wind to replace part of the propulsive power generated from fossil fuels. This article discusses the status quo of the WASP technological growth within the maritime transport sector by means of a secondary data review analysis, presents the potential fuel-saving implications, and identifies key factors that shape the operational efficiency of the technology. The analysis reveals three key considerations. Firstly, despite the existing limited number of WASP installations, there is a promising trend of diffusion of the technology within the industry. Secondly, companies can achieve fuel savings, which vary depending on the technology installed. Thirdly, these bunker savings are influenced by environmental, on-board, and commercial factors, which presents both opportunities and challenges to decision makers.
