  • As the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex VI strengthening air pollutants including sulfur oxides (SOx) and nitrous oxides (NOx), dual-fuel engine has become one promising solution. The study will cover a comparison case study between Caterpillar’s MaK brand 9M46DF dual-fuel engine and 9M43C diesel engine on an 868 TEU container feeder vessel sailing in Baltic Sea. The data for this study were mainly provided by Caterpillar Motoren GmbH in Kiel and Zeppelin Power System GmbH in Hamburg, Germany. This research discusses the advantages and challenges in both technical and economical consideration of dual-fuel engine. The technical analysis discusses engine’s performance, fuel consumption, exhaust-gas emission, and fuel storage system; while economic analysis covers fuel cost, initial investment, and payback period. It is concluded that dual-fuel engine has a significant lower pollutant emission and lower fuel cost, but high initial investment and LNG fuel system is required. Simple payback period calculation as function of price difference between LNG and MGO, and initial investment is shown.
