heal.abstract	This thesis presents a comprehensive analysis of different propulsion configurations within the megayacht industry, focusing on the evaluation of energy efficiency, economic viability, and environmental impact. Through the detailed modeling of five distinct propulsion configurations across two operational scenarios, employing real-world data and the simulation capabilities of PSE gPROMS framework, this research delves into mechanical, hybrid, and diesel-electric systems. Each configuration is evaluated based on thermal efficiency, fuel consumption, operational costs, and CO2 emissions, providing a comprehensive understanding of their performance. Key to this research is the utilization of propulsion-velocity curves, electrical consumption profiles, and a carefully constructed operational timetable that mirrors potential voyages of a megayacht during the peak summer season. This approach allows for a precise assessment of propulsion demands and the environmental footprint associated with each voyage. Despite exploring the advantages of alternative propulsion solutions, the findings reveal a compelling narrative: the mechanical (traditional) propulsion configuration not only competes favorably with its modern counterparts but also emerges as the most thermally efficient option. This outcome challenges prevailing assumptions about propulsion technologies, suggesting a reevaluation of traditional systems' role in future maritime operations. Moreover,the research identifies the potential of battery-equipped configurations to reducing shore power costs, underscoring the value of sophisticated power management strategies. The thesis also engages with prevailing market trends, highlighting the increasing preference for eco-friendly and technologically advanced maritime solutions. This market orientation suggests a potential for higher resale values for vessels incorporating sustainable technologies, aligning with broader environmental objectives. Concluding, this study prompts a reevaluation of propulsion choices in the megayacht industry, highlighting the efficiency of mechanical systems equipped with modern diesel engines alongside newer technologies. It suggests that achieving sustainability and operational efficiency does not only rely on cutting-edge innovations but also on optimizing existing solutions. This thesis contributes to the sustainable maritime operations dialogue, advocating for deeper research into how traditional propulsion can meet modern efficiency and environmental standards.	en
