How Many Gallons of Fuel Does A Cruise Ship Use?
Table Of Content
Therefore, cruise operators often find a balance between maintaining a reasonable cruising speed to meet itineraries and minimizing fuel usage. It’s important to note, however, that fuel consumption and costs can vary widely based on the factors mentioned above, as well as the specific fuel efficiency of the ship’s engines and other systems. The cruise ships have a bottom-heavy design when it comes to bulk fuel storage. However, the tanks are not cumulative but distributive across the length. This accounts for the dynamic stability and also uses less space for higher passenger capacity. Cruise ships are the biggest and mightiest sea-going vessels available in the shipping industry at present.

With such high speed, the specific fuel oil consumption goes way over the bar. Cruise ships consume a lot more fuel in comparison to the average cargo vessel. However, this stands as an exception to the large container ships that also have higher consumption limits. Therefore, this needs one to understand how much fuel a cruise ship uses and why it is relatively high. The specific consumption of fuel for power generation at the European cruise terminals is available.
Sailing Speed
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. In addition to CO2, cruise ship fuel consumption also results in the emission of other air pollutants, including sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM). These pollutants can have detrimental effects on both human health and the environment. SO2 emissions contribute to acid rain, which harms ecosystems, while NOx emissions contribute to air pollution and the formation of smog.
Conventional diesel cruise ship engine
Considering the Oasis-class Royal Caribbean vessel is made to sail for at least seven-day itineraries, you can only imagine how much diesel fuel the 227,500 gross ton Harmony of the Seas could truly hold. 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. If you’ve ever had an experience like this, you can agree that carrying more weight requires more fuel. In addition, cruises with longer itineraries tend to require more fuel than shorter ones. For example, a two week cruise will consume more than twice as much fuel as a one week cruise.
How Much Does It Cost to Fuel a Cruise Ship?
The first is that the average cruise ship will burn between gallons of fuel per nautical mile. The second is that a good-sized barge can hold about 450,000 gallons of fuel to supply to cruise ships. While these fuel consumption figures may seem high, it’s important to consider the massive scale of these vessels and the services they provide. Cruise ships are essentially self-sustaining cities, with onboard restaurants, swimming pools, theaters, shopping areas, and more. All of these amenities require energy, which is supplied by the ship’s engines running on fuel. The Guardian reported that the Harmony, owned by Royal Caribbean, has two four-story high, 16-cylinder Wärtsilä engines.
These considerations are always present in the accounting of the engine performance too. 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.
Size Of A Cruise Ship And Refueling Time
Cruise ships, with their vast size and luxury amenities, have a significant fuel consumption requirement to power their operations. However, the cruise industry is actively addressing this challenge by exploring innovative solutions and embracing sustainable practices. The size and capacity of cruise ships, along with their speed and chosen itineraries, directly impact fuel consumption. In recent years, cruise lines have been exploring alternative fuel technologies and hybrid engine systems to further enhance fuel efficiency and reduce environmental impact. Liquefied Natural Gas (LNG) is gaining attention as a cleaner-burning fuel option for cruise ships, as it produces fewer emissions compared to traditional marine diesel fuel. LNG-powered cruise ships have the potential to considerably reduce greenhouse gas emissions, air pollutants, and particulate matter.

This will also cover the duration of port stays, the sailing environment, and the carrying capacity. The same is considered for surplus bunkers if the engine department has knowledge of inclement weather. If the tank is half full, it will still take a few days — 50 hours — to refuel it back up to full.

The largest passenger steamship (before hitting an iceberg on April 14, 1912) was the Titanic, powered by both reciprocating engines and turbines, able to generate 50,000 horsepower (37 megawatts). Azipod marine ship propulsion is a combination of both steering and propulsion systems. Conventional marine propulsion systems use a two-stroke engine connected to a shaft, that passes through a stern tube and shaft tunnel to connect to the propeller outside the hull in the ship's aft/stern. All ships rely on propellers/screws to be pushed through the water, providing forward and reverse motion.
Though some cruise ships run on bunker fuel, most use a more environmentally friendly fuels like gas, diesel, marine diesel, or liquified natural gas. With regard to storing bulk fuel, cruise ships have a bottom-heavy design. This explains the dynamic stability and also takes up less room for a larger passenger capacity. Thus, the primary function of the settling tank is to primarily separate any water from the regular diesel fuel. To comply with coastal regulations, cruise ships’ general bunkers must be of a high caliber and cost. With a whopping 143,730 tonnes, P&O’s flagship ship, Britannia, resembles a five-star hotel at sea.
It shows the fuel consumption per hour and the KW requirement for the port operations. These figures vary significantly at sea where all entertainment sources are driven by shipboard power. For cruises varying between 150 to 250 meters, the fuel usage goes down fast.
The changing regulations are also dictating the adaptability of these ships to use electric propulsion. Modern vessels also use dual propulsion, using both electric and fuel resources. Very rare do cruise ships rely on the fuel of lower quality for power generation.
And the world’s largest cruise ships, like Royal Caribbean’s Oasis class, can consume up to 250 metric tons of fuel per day or 80,645 gallons per day. That’s more fuel than you’ll use driving cars throughout your lifetime. The fuel cost for the Oasis-class vessels is estimated to be around $300,000 per day. The amount of time cruise ships can spend at sea depends on how much fuel they consume. The number of port visits, average speed, and weather conditions affect fuel usage. On average, a cruise ship can hold around one to two million gallons of fuel.
