5000GTのRo-Ro旅客フェリーを対象に、ディーゼル機械式(DM)・ディーゼル電気式(DE)・パラレルハイブリッド(PH)の3推進方式を技術経済的・環境的に比較した研究。AISデータに基づく運航プロファイルを用い、20年間の燃料消費・CO₂/NOₓ/SOₓ排出・ライフサイクルコストを評価。PHはDM比で年間燃料消費とCO₂を25.0%削減し、DE比でも14.3%削減。CAPEXはDM比31%増だが、運航費削減により投資回収期間は約2.15年と試算された。
English
A techno-economic and environmental comparison of diesel-mechanical, diesel-electric, and parallel hybrid propulsion for a 5000 GT Ro-Ro passenger ferry, using AIS-derived operational profiles over a 20-year horizon. The parallel hybrid cuts annual fuel use and CO2 by 25.0% versus diesel-mechanical and 14.3% versus diesel-electric, with ~31% higher CAPEX but a payback of about 2.15 years from operating savings.

📄 Abstract(原文)
The role of short sea shipping in regional logistics operations is very important. With pressures from IMO regulations (EEXI and CII) growing, the maritime industry must adopt more efficient propulsion. The impact of marine technology choice on the shipping industry and its effect on the entire economy is often overlooked by society. In this paper, a techno-economic and environmental comparison of three propulsion architectures for a 5000 GT Ro-Ro passenger ferry is presented. These architectures include conventional diesel-mechanical (DM), diesel-electric (DE), and parallel hybrid (PH). The project developed a simulation framework leveraging operational profiles that were obtained from Automatic Identification System (AIS) data through the national AIS archive Marine Cadastre. The fuel consumption, emissions (CO₂, NOₓ, and SOₓ), and life-cycle cost (LCC) of all three systems were evaluated over a 20-year planning horizon. The findings demonstrate that PH approach is responsible for a 25.0% decline in yearly fuel consumption and CO₂ emission as compared to DM baseline and 14.3% compared to DE system. While the PH system necessitates 31% more CAPEX than the DM system, its payback period is approximately 2.15 years because of significant savings on operating cost. This framework, combining quantitative evidence and systematic decision-making processes, will help ship owners and other policy makers choose the best propulsion technologies to decarbonise short-sea shipping fleets.
