What type of engine is used in tankers?

Tankers typically use large, slow-speed diesel engines, specifically two-stroke or four-stroke engines, designed for efficiency and reliability over long distances. These engines are often turbocharged to enhance performance and fuel efficiency, as they must handle the heavy loads and continuous operation required for transporting vast amounts of cargo. Additionally, some modern tankers are beginning to explore alternative propulsion systems, including LNG (liquefied natural gas) engines, to reduce emissions.
