Because ocean-going vessels make port in and travel through waters governed by various jurisdictions with different environmental concerns, they must sometimes switch fuels to comply with local laws. These bunker fuels — used to power engines and auxiliary equipment — typically come in three types. Here, Fuelman Inc., a supplier of diesel, propane, and other bulk fuels in Honolulu, HI, explains what these are and why they are used.

Types of Bunker Fuel Used to Power Ships

1. Heavy Fuel Oil (HFO)

Heavy fuel oil is comprised of what is left after crude oil is refined into gasoline and diesel. It is inexpensive, but it has a high impurity content and produces a number of exhaust gases that impact the environment, such as nitrogen oxide and carbon dioxide. Therefore, its use is curtailed in some regions.

2. Low Sulfur Fuel Oil (LSFO)

Low sulfur fuel oil, which must contain less than 1% sulfur content, is one of the cleanest burning fuels available. Because it does not produce the same amount of soot and scale as high sulfur fuels, it reduces the amount of maintenance required, improves engine life, and lowers the amount of pollution created. However, it costs more than HFO.

3. Marine Diesel

Marine diesel is a mixture of heavy fuel oil and gas. It is very efficient and cost-effective, and the lower operating temperature of diesel prolongs the ship’s engine life. However, the fuel has a high sulfur content, and many jurisdictions limit its use.
