Auxiliary Propulsion Based on Wave Energy Converters
, 2021 This study presents a proof of concept for new auxiliary propulsion. The proposed design includes open to the sea ship compartments. Seawater oscillates inside the specially shaped compartments due to the relative ship motions in waves. The curved profile of these compartments deflects the water backwards from its natural vertical flow, and the water ...
