Marine fuels are specialized types of fuel used to power ships and other vessels. These fuels are designed to meet the specific needs of marine engines, which often operate under different conditions than land-based engines. Common types of marine fuels include bunker fuel, marine diesel oil, and liquefied natural gas (LNG). Each type has distinct properties and uses, depending on the size and type of the vessel. The choice of marine fuel can impact both performance and environmental regulations. For instance, bunker fuel is heavy and less refined, making it cheaper but more polluting. In contrast, LNG is cleaner and produces fewer emissions, aligning with global efforts to reduce the environmental impact of shipping.
