Abstract :Maritime transport is crucial for global trade, transporting over 10 billion tons of containers annually. Conventional propulsion systems like diesel engines have been used for years, but the International Maritime Organization (IMO) is pushing for alternative solutions due to increasing environmental impacts. In 2019, international shipping, including container ships, accounted for 2.1% of global greenhouse gas emissions. The study aimed to improve the efficiency of the diesel electric propulsion system. To evaluate one such solution, this study simulated an offshore container ship’s diesel-electric (DE) propulsion system, assessing fuel consumption and emissions across three scenarios. The load profile was created using the ship’s navigation data, and the simulation aimed to build configurations for generators to run at maximum load and batteries to contribute to power balance. Unlike prior works limited to port or coastal vessels, the proposed approach evaluates three distinct propulsion scenarios, including battery-assisted operation and zero-emission port adaptation, within a unified methodological structure. This study selected the container ship type because it frequently performs maneuvering operations and operates under variable engine load conditions during these periods. The results of three scenarios indicate fuel consumption reductions of 2.9%, 5.3%, and 10.38% respectively
