This paper aims to analyze the performance of the dual-fuel diesel engine effect of variation of the gas mixture. Medium-speed diesel engines from the passenger ship 3200 DWT has been chosen a case study in consideration for the dual-fuel engine conversion. The analysis was performed based on the result of the simulation model by computational fluid dynamics. Mean effective pressure (MEP) as engine performance indicator has obtained from the simulation, thus the power and thermal efficiency calculated using empirical equations. Five variations of a gas mixture are determined i.e. 30%, 40%, 50%, 60%, 70% to obtain performance changes. The results of the analysis show different performance characteristics on the increase of gas mixtures. The optimum performance of the dual-fuel engine was obtained at a 60% gas mixture where achieved its maximum power and thermal efficiency.
