Each of the Star Cruises "Global-Class" vessels have three "Azipod XO" thrusters. All ships have installed ABB's "Intelligent Maneuvering Interface" and the "OCTOPUS" software optimizing fuel consumption and energy management. Currently, almost 2/3 of all large-sized cruise vessels, icebreaking ships, and high ice-class cargo ships are with Azipod propulsion. A smaller ship will require less fuel to travel the same distance than a larger ship. The amount of fuel a cruise ship uses depends on its size and average speed. A large cruise ship can use up to 250 tons of fuel per day, or about 80,000 gallons, on average.
Conclusion: The Future of Cruise Ship Fuel
For example, a third-generation engine and its performance between eco speed to full load vary considerably. This means every engine will have a unique consumption chart depending on these characteristics. Cruise vessels mostly dwell around the coastal areas with occasional visits to the deep ocean. A major reason for this is that passengers want to indulge in the onboard and shore enjoyment together. Hence, once the vessel route comes through, the bunker estimations go underway. "We built a machine to allow all of these different experiments that normally you would need to be on a cruise ship to run," said Matt Tabor.

A Cruise Ship Can Hold How Much Fuel?
This blog helps over a million people to plan their cruises each month. In terms of cost, if the current price of Heavy Fuel Oil (HFO) is $3 per gallon, it would cost approximately $42 to propel the ship one mile. Get ready to discover just how much fuel these floating cities can hold. Strictly Necessary Cookie should be enabled at all times so that we can save your preferences for cookie settings.

On average, a large cruise ship may consume between 30 to 50 tons of fuel per day, translating to about 1.25 to 2.08 tons per hour, assuming the ship is operating continuously for 24 hours. The fuel efficiency of a cruise ship is much lower than that of most other forms of transportation, largely due to the massive size and weight of these vessels. They may carry several hundred thousand gallons (up to a couple of million litres) of fuel, sufficient for shorter voyages. To conclude, cruise ships take a lot of fuel – millions of gallons worth. Although it may be hard to fathom this amount of fuel, it makes sense for massive ships that spend days or even weeks at sea.
Moreover, we also consider the changes in the propulsion technology affecting fuel consumption and storage. The primary requirement of these cruise vessels is passenger safety and engagement. In such conditions, their maintenance stoppages will be minimum and with high safety awareness. If you regularly drive a car, you likely notice how different factors affect the amount of fuel you consume. For example, if you decided to go on a road trip with your truck towing a boat, you probably had to stop for gas more often than the last trip you took with your vehicle alone.
We’re also proud to take our guests to the most breathtaking destinations around the world, including hidden harbors, aboard our small, elegant ships. All our ships carry no more than 350 passengers, and we cruise at comfortable, scenic and fuel-saving speeds. Therefore, ship designers consider how both the forces in the air and water impact fuel consumption to design more efficient ships. By optimizing the hull form and surface, as well as the propellers, a boat might use up to 8% less propulsion fuel. Removing slime, depending on how much buildup there is, can yield anywhere from 7 to 30% reduction in propulsion fuel consumption. It’s hard to imagine any size cruise ship floating as if it were weightless across the water, but that’s part of the engineering magic.
What Fuel Do Cruise Ships Use?
Indeed, the demands of a cruise ship are extraordinary and so is the fuel consumption. Of the many fascinating questions cruise ships inspire, the most common is how much fuel they use. In the next section, we will explore the technologies employed by the cruise industry to enhance fuel efficiency and minimize its environmental impact. By considering and incorporating these factors into their operational strategies, cruise lines can effectively manage and reduce fuel consumption. This not only benefits their bottom line but also contributes to sustainable cruising and minimizing impact on the environment.

Cruise ships from companies like Royal Caribbean are among the most enormous transportation vessels in the world. Roughly the size of an aircraft carrier, the massive passenger liners hold millions of gallons of fuel between five to six engines. Cruising speed is also another factor that you must take into consideration. Larger cruise ships require more fuel to reach certain speeds due to the power needed to propel the vessel forward. At a petite 878 feet long and 75,500 tons, this ship is much more fuel efficient.

That’s about the length of the famous Hollywood sign in Los Angeles, California. Finally, the length of the sailings the ship is built for can also affect how much fuel the ship can hold. The longer the ship’s sailings, the more fuel it’ll be required to hold, as cruise lines would want to keep refueling stops during the cruise to a minimum. Fuel may be the last thing you think about on your cruise, but it’s very important. The powerplant is controlled by ABB's PEMS (Power and Energy Management System), which also optimizes the onboard energy use.
Its 95 percent methane composition releases water vapor and a much smaller amount of carbon dioxide. Transportation industry giants are turning towards LNG fuel to reduce carbon emissions in increase fuel efficiency. Size is an essential factor in cruise ship fuel consumption and fuel efficiency. With the same distance, a smaller ship will have less fuel consumption than a larger ship, similar to motor vehicles on the road. As the cruise industry continues to grow and evolve, there is a concerted effort to reduce the environmental impact of cruise ships. The industry’s commitment to sustainable practices, technological advancements, and regulatory compliance demonstrates its dedication to preserving the oceans and the beautiful destinations they visit.
However, the most important factor determining this is the cruise ship’s size. Generally, a large cruise ship up to 1,100 feet in length can carry as much as two million gallons of fuel on board. To compare, smaller yachts usually carry 200 to 1200 gallons of fuel onboard. Similar to a car, traveling at higher speeds means an increase in aerodynamic drag, which directly impacts fuel use. Given that most cruise ships travel at 21 to 24 knots, this isn't often an issue.
Cruise ship operators continually seek to manage and reduce their fuel costs, which represent a significant portion of their operating expenses. Freedom class ships are all 1,112 feet long with an average speed of 21.6 knots. They are rumored to have a standard fuel consumption of 28,000 gallons of fuel per hour, which seems much higher than other similar ships. Their propulsion systems are state-of-the-art, providing a 10 to 15 percent fuel savings overall. In the case of the Queen Mary 2, the ship is huge at 1,132 feet long and a weight of 151,400 tons.

Most owners always provide their ships with surplus bunkers for safe navigation under such conditions. Modern cruise vessels hit speeds of 22 to 24.5 knots during their international voyages regularly. This means their operation in the range of 85% load and above is quite frequent too. Under such conditions, the consumption increases more than 40% of the eco speed performance. Beyond the length of sailing, the itinerary also plays a vital role in fuel costs.
The amount of fuel consumed by a cruise ship can vary greatly depending on several factors, including the ship’s size, speed, itinerary, and the technology implemented to improve fuel efficiency. In recent years, there has been growing concern about the environmental impact of cruise ships and their fuel consumption. These ships incorporate a complete ABB propulsion - Azipods, electric power plant, computer automation, and software. Crystal cruise ships are powered by two "Azipod D" units allowing navigation in polar destinations.
Additionally, cruise operators are adopting measures to manage passenger density and optimize energy consumption onboard. Many cruise lines are designing some of their new ships to run on LNG as it’s a clean-burning fuel that is better for the environment. The newer class vessels are more commonly coming out as LNG, including MSC’s new World-class, Carnival’s Excel-class, and Royal Caribbean’s Icon of the Seas.
Cruise ships emit greenhouse gases and air pollutants, contributing to climate change and air pollution. However, the industry has been actively exploring emission control technologies, alternative fuels, and sustainable practices to mitigate this impact and promote environmental sustainability. Larger cruise ships with higher passenger capacities typically consume more fuel due to their increased size, weight, and energy requirements. On the other hand, smaller vessels with fewer amenities and a lower passenger capacity may have lower fuel consumption rates.
