本研究は、LNG二元燃料船の運航戦略を最適化するモデルを提案。炭素税、排出規制区域（ECA）、燃料価格割引、メタンスリップ率が燃料管理に与える影響を分析。極東-北西ヨーロッパ航路の実船を事例とし、LNGとVLSFOのバンカリング港と量、計画速力を決定。感度分析から、燃料価格差、炭素税率、メタンスリップ率が運航決定に大きな影響を与えることを示した。
English
This study develops an optimization model for operational strategies of LNG dual-fuel ships considering carbon tax, ECA policies, fuel price discounts, and methane slip. Using a real vessel on the Far East–Northwest Europe route, it determines bunkering ports/quantities and planned speeds. Sensitivity analyses show that fuel price difference, carbon tax rate, methane slip rate, and fuel price discounts significantly impact decisions. The findings help shipping companies comply with emission policies while reducing costs.

In the global GX context
This paper offers a practical optimization framework for global shipping companies facing tightening emission regulations (IMO, EU ETS) and carbon pricing. The case study on a major trade route demonstrates how fuel price discounts and methane slip rates interact with regulatory compliance, providing valuable insights for both operators and policymakers.

📄 Abstract（原文）
The liner shipping industry is thriving in the low-carbon transition, and optimizing operational strategies for liquefied natural gas (LNG) dual-fuel ships has become a research hotspot. This research examines the impacts of the carbon tax, emission control area (ECA) policies, fuel price discounts and methane slip rate on fuel management strategies. Firstly, to reduce liner operating costs and adhere to ECA policies, this study develops a basic optimization model. Further, the model is extended to take into account the impact of fuel price discounts. Secondly, by linearizing multiple nonlinear terms, the operational strategies are obtained. Thirdly, taking a real vessel sailing between the Far East and Northwest Europe as a case study, this study identifies the ports for LNG and very low sulfur fuel oil (VLSFO) bunkering, determines the bunkering amounts and calculates the planned speeds. Furthermore, sensitivity analyses are conducted on fuel price difference, carbon tax rate and methane slip rate. Results show that fuel price difference, carbon tax rate, methane slip rate and fuel price discount exert a significant impact on ship operational decisions. To ensure the effectiveness of maritime decarbonization regulations, authorities should monitor ship engines with high methane slip rates. This study offers important references for shipping enterprises to meet ship emission policies and simultaneously cut operational costs.
