UN’s Sustainably goal 13 (Climate action) addresses the need to reduce harmful emissions from all types of industrial and transport activities [1]. The Fourth IMO GHG Study 2020 estimated that GHG emissions from shipping in 2018 accounted for some 2.89% of global anthropogenic GHG emissions [2]. As well as for other transport sectors, national and international maritime regulatory bodies have defined goals for reduction of greenhouse gases within given time limits (2030 and 2050). Many of these goals have been defined from an optimistic view of introduction of new hull designs and propulsion technologies, fuels and operational measures such as fleet capability utilization and routing. The present economic reality indicates that it may be difficult, if not impossible, to reach the goals in time. Wind-Assisted Propulsion Systems (WAPS) have been recognised as an essential contributor to a sustainable maritime energy transition. WAPS offer a cost-efficient carbon free source of propulsion, contributing to energy efficiency and eventually limiting the cost and volume burden of upcoming zero-carbon fuels. Maximising the potential of this technology in operation requires skilled seafarers and effective training programs.
