Modern society faces the difficult task of solving environmental issues to achieve sustainable economic growth and meet increasing energy demands. The operation of ships consumes large amounts of fuel and emits harmful gases, significantly contributing to air pollution and climate change. In accordance with the strengthening international environmental regulations, this study focuses on LPG fuel as an eco-friendly alternative with potential for achieving low CO₂ and NOx emissions and operational-cost efficiency. The performance of a developed 200-kW class LPG engine under various load scenarios was experimentally evaluated and its performance was verified by comparison with the diesel engine of an 8000-ton class training ship emergency generator. Based on the experimental results, this engine exhibited low NOx emissions commensurate with the International Maritime Organization (IMO) Tier III regulations, and showed relatively low CO emissions and fuel consumption compared to diesel engines. The engine was found to have economic and environmental advantages over conventional diesel engines, and its potential as a marine engine was confirmed based on its performance according to the load. These findings are expected to provide a basis for future research and development of alternative fuels and serve as an experimental benchmark for various types of vessels equipped with LPG engines
