Review of Wind-Assisted Propulsion Systems in Maritime Transport

The maritime industry is going through a technology transition, aiming to have carbon-neutral propulsion systems. A significant trend of orders for ships with alternative propulsion has been observed. A favorable means to meet the decarbonization requirements imposed by IMO (International Maritime Organization) is to operate vessels with sustainable energy. Harvesting wind power and its conversion into ship propulsion are gaining popularity due to emission reductions and expected reductions in fuel consumption. This paper reviews recent studies on wind-assisted propulsion systems (WAPSs), the different aspects of using sail applications in the maritime industry, and the types of wind-assisted propulsion systems. The study also presents the latest developments in WAPS systems offered by leading maritime market manufacturers and their applications on existing vessels. The article is based on a literature review (peer-reviewed articles), the information provided by wind propulsion systems manufacturers and internet research.
