Bunker Fuel

Bunker fuel, also known as heavy fuel oil, is a type of fuel that is typically used by large ships and other marine vessels. It is a viscous, thick, and heavy liquid that is produced from crude oil during the refining process. Bunker fuel has a relatively high sulfur content compared to other fuels, which can contribute to air pollution and environmental concerns. However, it is used by many shipping companies because it is relatively inexpensive and provides a lot of energy per unit of volume.
