A ship propulsion system is a complex system that provides the necessary force to move a vessel through water. This system includes various components such as engines, propellers, gearboxes, and shafts. The type and configuration of the propulsion system depend on the size, speed, and purpose of the vessel. The current paper reviews the main benefits and challenges of different ship propulsion systems. There are several types of ship propulsion systems, including conventional mechanical, electric, and hybrid. Conventional mechanical systems use diesel engines and shafts to turn the propeller, while electric systems use electric motors powered by generators or batteries. Hybrid systems combine both conventional and electric propulsion technologies to improve efficiency and reduce emissions. The choice of propulsion system can have significant implications for a vessel’s performance, fuel consumption, and environmental impact. Therefore, it is important to consider all factors when selecting the most suitable system for a particular vessel.
