Wind-assisted propulsion systems (WAPSs) are seen as a technology that could reduce the fuel consumption from ships and, consequently, lower their greenhouse gas (GHG) and other emissions. The potential of wind assisted propulsion systems as a power source in the shipping sector is analysed in a new report released by the European Maritime Safety Agency (EMSA). The report was commissioned by EMSA under framework contract EMSA/OP/43/2020 to a joint venture of the American Bureau of Shipping, CE Delft and Arcsilea.
