Sustainable Marine Engineering Practices: Integration of Renewable Energy Systems on Ships

Igor Astrakhovych

Abstract: The study presents a comprehensive analysis of current approaches to sustainable marine engineering, with particular emphasis on the synergistic integration of various renewable-energy technologies on board a vessel. The objective is to evaluate existing solutions including wind-assist propulsion systems, photovoltaic panels, and power plants operating on alternative fuels in terms of their combined impact on energy efficiency, economic return, and regulatory compliance. The methodological framework comprises a systematic review and meta-analysis of scientific publications and industry reports published in recent years. The results demonstrate that hybrid power arrangements combining several types of renewable energy sources achieve greater emission reductions and lower operational costs than the deployment of stand-alone technologies. Scientific novelty is represented by a comprehensive multicriteria method for selecting the optimal configuration of hybrid renewable-energy solutions that simultaneously accounts for technical, economic, and regulatory factors. The findings will be of value to naval architects, fleet owners, classification societies, and researchers engaged in the decarbonisation of maritime transport.
