How Much Fuel Does a Cruise Ship Use a Day?

By Robert Palmer

Cruise ships are a popular way for people to travel and explore the world. They offer a luxurious and stress-free way to vacation, but many people are unaware of how much fuel these huge vessels use every day.

The type of cruise ship, its size, and the route it takes all play a role in how much fuel it will consume each day. The bigger the ship and the longer the voyage, the more fuel it will require.

On average, most cruise ships consume between 200-400 gallons of fuel per hour while they are in operation. This means they can use up to 9,600 gallons of fuel in just one day!

The majority of cruise ships run on heavy fuel oil (HFO), which is a type of petroleum product that is designed for high-speed diesel engines. This type of fuel is not only cost-efficient but also produces fewer emissions than other types of oil used in shipping vessels. However, although HFO is cleaner than traditional marine fuels, it still contributes to air pollution and has an impact on global warming.

Some large cruise lines have taken steps to reduce their environmental footprint by investing in more efficient engines or using alternative fuels such as liquified natural gas (LNG). These alternative fuels produce fewer emissions than HFO and can help reduce the amount of fuel used by up to 20%.


Cruise ships are incredibly popular forms of travel but unfortunately they also use a large amount of energy each day. The amount varies depending on factors such as size and route length but on average they can consume up to 9,600 gallons in just one day! Cruise lines have started investing in more efficient engines and alternative fuels to reduce their environmental footprint but there’s still plenty that can be done in order to make them even more eco-friendly.
