This study evaluates power system options for 84,000 DWT bulk carriers on the China-Baltic route, integrating life-cycle cost, geopolitical risk, and regulatory alignment. Comparing six alternatives, it finds methanol-ready designs offer the best risk-return profile under EU ETS and FuelEU Maritime, recommending a gradual transition strategy rather than a single final fuel.

📄 Abstract（原文）
Against the backdrop of continuously tightening international maritime decarbonization policies and frequent geopolitical disruptions along key shipping routes, the selection of power systems for 84,000 DWT bulk carriers is no longer merely a matter of initial cost comparison but involves comprehensive decisions regarding fuel prices, carbon costs, supply networks, route detours, and asset option values. This study examines the route from China's northern ports to the Baltic Sea, establishing an integrated evaluation framework encompassing "full life cycle cost (LCC) – geopolitical risk – regulatory alignment," and compares six options: conventional diesel engines, energy-efficient optimized diesel engines, LNG dual-fuel systems, methanol reserve/methanol dual-fuel systems, green methanol dual-fuel systems, and ammonia fuel reserves. The research indicates that under static cost assumptions, energy-efficient optimized diesel engines still offer the lowest short-term cost advantage; however, when factors such as the EU Emissions Trading System (EU ETS), FuelEU Maritime regulations, route detour risks, and future retrofit options are incorporated into the assessment, the methanol reserve option demonstrates a superior risk-return profile due to controllable initial premiums, clearer retrofit pathways, and stronger regulatory compliance. The study concludes that at this stage, 84,000 DWT bulk carriers should not simply rely on a single "final fuel" but rather adopt a gradual transition strategy combining "high-efficiency diesel foundations + alternative fuel reserves + operational risk hedging."
