本論文は、船舶の脱炭素化に向けた出力制限システム（EPL、SHaPoLi）と代替燃料の統合戦略を体系的に提示する。コントロールピッチプロペラと電子遠隔制御による出力制限が柔軟性に優れ、SHaPoLiは燃料消費とCO2排出削減に高い効果を示すが導入コストが高い。経済分析により運転コスト削減の可能性を確認し、代替燃料との併用が最大の炭素削減をもたらすと結論づけている。
English
This paper systematically presents staged recommendations for integrating power limitation systems (EPL and SHaPoLi) with alternative fuels to decarbonize maritime vessels. It finds that power limitation via controllable pitch propellers with electronic remote control offers high flexibility, and SHaPoLi achieves greater fuel and CO2 reductions despite higher capital costs. Economic analysis shows operational cost savings, and pairing with alternative fuels yields the largest carbon footprint reduction.

📄 Abstract（原文）
This article addresses the operational challenges facing maritime vessels in the context of decarbonization, with a focus on developing staged recommendations for the integration of power limitation systems and alternative fuels. The systematisation of existing decarbonization problems in the maritime sector and the establishment of their interrelationships constitute the framework for developing coherent decarbonization strategies for the industry. The analysis of alternative fuels identifies the key factors that drive fuel selection in practice. The analysis of contemporary energy consumption regulation technologies has shown that power limitation systems operating through controllable pitch propellers (CPP), integrated with electronic remote-control systems, provide the highest flexibility in managing propulsion characteristics without altering engine rotational speed. The comparative analysis of the engine power limitation (EPL) and shaft power limitation (SHaPoLi) systems has confirmed that SHaPoLi offers a greater potential for reducing fuel consumption and carbon dioxide (CO2) emissions; however, it comes at higher capital expenditure at the implementation stage. Pairing power limitation with alternative fuels shows that deep cuts in the sector’s carbon footprint are within reach. The economic analysis of power limitation system deployment has revealed the potential for achieving considerable operational cost savings, with a balanced consideration of capital investments and operational benefits. Future research should target the optimisation of EPL and SHaPoLi systems and their integration with other energy-saving technologies. Transitioning to alternative fuels in parallel offers the greatest cumulative reduction in the sector’s carbon footprint.
