heal.abstract	The maritime industry faces increasing pressure to reduce greenhouse gas emissions and improve energy efficiency in accordance with the International Maritime Organization’s (IMO) decarbonization targets. To meet these objectives, ship operators are exploring technologies that reduce fuel consumption and environmental impact. Among the most promising measures are Wind-Assisted Propulsion (WASP) systems, which harness renewable wind energy to support conventional propulsion. This thesis aims to assess the impact of such technologies on fuel consumption and emission reduction, with a specific focus on the suction-based eSAIL system applied to a bulk carrier case study. The work introduces a computation model, with formulas that could be applied to real operating conditions. The main resistance components established in the methodology—calm-water resistance, added resistance from wind and waves, additional resistances from drift and rudder deflection—are linked through propeller open-water characteristics to determine propulsion power and fuel consumption. A series of computational analyses were carried out to evaluate ship performance and fuel consumption under varying wind conditions. The results showed that the integration of the suction-based eSAIL system can lead to fuel savings of up to 40 % in a realistic sea-going scenario, corresponding to typical service speed and wind conditions. Additional scenarios were introduced for different sea states, demonstrating that system could be beneficial across a wide range of environmental conditions. These outcomes demonstrate the strong potential of wind-assisted propulsion systems to reduce fuel consumption and emissions, contributing to the ongoing decarbonisation of maritime transport. Overall, this study highlights that the further development and practical adoption of WASP could play a key role in achieving a more energy-efficient and sustainable future for the shipping industry.	en
