Wind-assisted propulsion is emerging as a cornerstone of maritime decarbonisation. Reviewing sails, rotor technologies, and kites, the analysis assesses emissions-reduction potential, operational benefits, performance-prediction challenges, and implementation risks. The findings highlight the need for full-scale validation, robust economic assessment, and structural integration to accelerate sustainable shipping adoption globally going forward.

Accurate prediction of aerodynamic interactions is essential for effective wind-propelled ship design. Using RANS simulations of a coaster equipped with Flettner rotors, researchers quantified how vessel structures and neighbouring rotors influence performance. The resulting correction model improves thrust estimation accuracy, supporting better propulsion integration, optimisation, and efficiency worldwide today overall.

Decarbonising shortsea shipping will require substantial investment in fleet renewal, retrofits and emerging green technologies. By estimating transition costs, vessel replacement needs and wind-assisted propulsion opportunities, the analysis quantifies the pathway toward lower-emission coastal transport. The findings strengthen strategic planning, policy development and sustainable maritime growth globally for future resilience.

Standardised full-scale verification is becoming essential as wind-assist technologies move into mainstream commercial shipping. Using rotor-sail trials and statistical route analysis, researchers demonstrate a practical method for quantifying annual power savings with established tools and limited testing. The approach supports credible performance assessment, investment confidence, and wider industry adoption worldwide.

CFD analysis is expanding understanding of suction aerofoils as a wind-assisted propulsion technology. By evaluating lift, drag, boundary-layer suction, endplates, and ship-interaction effects, researchers quantified performance across operating conditions. The findings demonstrate strong potential for emissions reduction, provide valuable design data, and support broader adoption of wind-powered shipping worldwide today.

Accelerating adoption of Wind Assisted Ship Propulsion requires more than technology alone. This analysis identifies open innovation, financing, collaboration, and proactive environmental strategies as critical enablers for commercialization and scale-up. The findings provide actionable guidance for shipowners, policymakers, and technology providers seeking faster reduction of maritime emissions and broader deployment.
