Abstract： By analyzing key factors influencing decarbonization in the shipping industry，this study establishes an economic assessment method for low-carbon power system retrofits of ships operating on EU routes.A case study of an in-service VLCC （Very Large Crude Carrier） is presented， comparing annual fuel composition and cost expenditures over its remaining lifecycle under three retrofit pathways： carbon-neutral methanol，carbon-neutral ammonia，and carbon-neutral diesel.The results demonstrate that the proposed assessment method provides a scientific reference for decision-making in low-carbon retrofits.
Key words： EU routes； ships; low-carbon; power system retrofits; economic assessment
