Fuel consumption represents a pivotal factor in determining operational costs within maritime transportation, with direct implications for energy efficiency, environmental sustainability, and air pollution. This study aims to identify and evaluate the key determinants influencing fuel consumption, with the objective of optimizing these factors to enhance overall energy efficiency. A Multi-Criteria Decision-Making (MCDM) methodology was employed to systematically rank and prioritize the most significant criteria impacting fuel efficiency. The findings of the study indicate that compliance with sea conditions, optimal ship speed and the expertise of shipmasters (C3.2) are the most influential factors, followed by voyage planning that accounts for sea and weather conditions (C3.7). These results emphasize the critical role of operational strategies and the decision-making capabilities of personnel in minimizing fuel consumption. Moreover, the study identifies the significant contribution of maintenance practices, adherence to regulatory frameworks and environmental factors in shaping fuel efficiency outcomes. Quantitative analyses confirm that the implementation of energy-efficient practices can result in substantial cost savings and reductions in emissions. However, the achievement of stringent emission reduction targets may impose financial burdens on shipping companies, necessitating significant investments in fuel-efficient technologies and operational optimizations. Future research should focus on longitudinal voyage analyses, incorporating larger sample sizes and the development of mathematical models that align with the CO2 reduction targets set by the International Maritime Organization (IMO) for the years 2015, 2020, 2025, and 2030. This research provides valuable insights for maritime industry stakeholders and contributes to ongoing policy discussions, advocating for the establishment of standardized fuel consumption management practices that promote a more sustainable and economically efficient future for the shipping industry.
