Relevance. In the context of implementing a decarbonization strategy for maritime transport, the task of selecting the optimal ship modernization strategy becomes particularly relevant. Such a strategy must reduce CO₂ emissions while maintaining economic viability and technical feasibility. Given the diversity of available alternatives—differing in cost, payback period, environmental impact, and risk—a comprehensive decision-making method is required. Object of research: a multicriteria model for evaluating ship modernization strategies. Purpose: to apply the TOPSIS method to determine the most effective ship modernization alternative, taking into account economic, environmental, and engineering factors. Results. The study analyzes five ship modernization strategies. An integrated efficiency indicator was calculated using five evaluation criteria. The analysis results show that the slow steaming strategy presents the most balanced profile. Conclusions. The TOPSIS model proved effective for ranking modernization alternatives based on multiple criteria and can be used to support informed decision-making in sustainable maritime transport project management.Downloads
