How Much Fuel Does A Cruise Ship Use
Table Of Content
The energy consumption of these auxiliary systems can contribute significantly to a cruise ship’s overall fuel consumption. Cruise lines are constantly seeking ways to optimize fuel efficiency and mitigate the impact of ship size and passenger capacity. Innovative ship designs, such as streamlined hull shapes and improved hydrodynamics, can help reduce drag and improve fuel efficiency. Advanced propulsion systems, like pod drives or electric propulsion, are also being adopted to enhance energy efficiency. Diesel-electric engines are widely used in the cruise industry due to their higher fuel efficiency compared to gas turbine engines.
Cruise Ship Size and Passenger Capacity
Her designer Stephen Payne showed the advantages of pod-propulsion giving vessels increased maneuverability. The propellers (screws) of the QM2 ship are mounted on the pods which rotate 360 degrees and provide advanced maneuverability. He made the choice to put pods - though relatively new and yet untested for big ships. Royal Caribbean vessels of Oasis, Freedom, and Voyager classes have pod-propulsion as many other big ships, which is opposed to the fixed traditional screws which push in one direction only. 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.
Fueling a Cruise Ship FAQ
It is noteworthy that maintaining a balance between speed, itinerary, and passenger experience is crucial for cruise operators. While fuel-saving measures are important, providing an enjoyable and timely experience is equally vital. Therefore, cruise lines carefully evaluate speed and itinerary decisions to optimize fuel efficiency while meeting passengers’ expectations. Hence, these vessels can give you speeds of 20 knots and more with such consumption. Meanwhile, like their larger sisters, the medium-size cruises also have manoeuvring requirements.
Engine Generation And Consumption Characteristics
While cruise ship size definitions vary, generally, large vessels are those that carry more than 2,500 passengers. Windstar’s ships are on the smallest end of this range, as our vessels carry roughly 250 to 300 guests. The faster a cruise ship goes, the more fuel it burns because of the power required to propel the ship forward. This is one reason why cruise ships usually sail leisurely throughout your voyage. The frequency at which cruise ships need to refuel depends on how much fuel the cruise ship holds, which in turn depends on the size of the ship and other factors. However, most cruise ships can only spend about 12 days at sea without refueling.
On April 12, 2018, the VIKING LINE-owned ferry Viking Grace became the world's first-ever passenger ship equipped with a rotor sail utilizing wind power. This also made it the world's first hybrid vessel that uses both wind power and dual-fuel (diesel-gas) engines. When cooled to -160 C, it passes from gas to liquid, and its volume decreases over 600 times, making it very efficient for distribution. Short-distance LNG transportation is via trucks or smaller vessels (also barges) fitted with high-pressure tanks. Some of the lines (including Celebrity and Cunard) have suffered vessel breakdowns due to pod-bearing failures.

When it’s moving through thick ice and needs to use all five of its engines, the amount of fuel consumption increases to nearly 24,000 gallons of fuel per day. That’s because ships need their heaviest weights located at the lowest point possible, so their engine rooms are near the bottom of the vessel. Since engines must power ships through the water, they can be immense for massive vessels. For example, a nine-cylinder engine designed for a large cargo ship might be 65 feet long, 60 feet high and weigh about 1,500 tons. An engine of that size would take up about one-fifth of Windstar’s small 148-guest ship.
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. 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. This takes into account their short voyages as well as shorter port stays.
How much does it cost to fuel a cruise ship?
Battery power is used during turnaround navigation in ports when the onboard diesel-electric generators are switched off. As of 2019, Corvus Energy delivered its innovative product line "Orca ESS" to 200+ vessel conversion/upgrade projects, totaling 200+ MWh. Those who support the cruise industry point out that cruising has never been more popular. A solution is to have docked vessels plug into the port's shore power grid. Most of the world's largest cruise ports have such dockside electrical hookups, reducing bad emissions by up to 95%. The next scheme shows the dual-engine powerplant (Wartsila) and propulsion (Azipod) of the cruise ferryTallink Megastar.
How Often Do Cruise Ships Refuel?
The environmental consequences of cruise ship gas consumption include air and water pollution, oil spills, disturbance to marine life, and coral reef damage. However, the cruise industry is actively working to minimize its ecological footprint. Cruise lines are adopting fuel-efficient technologies, exploring alternative fuels like LNG, and integrating hybrid and electric propulsion systems. Cruise lines are investing in technologies and operational practices to improve fuel efficiency and minimize environmental impact. From utilizing diesel-electric or gas turbine engines to exploring alternative fuels like LNG, cruise operators are continuously striving to reduce emissions and dependence on fossil fuels. It is important to note that fuel consumption can vary significantly based on the type of engine installed on the ship.
Efforts are also being made to incorporate renewable energy sources into the auxiliary power systems of cruise ships. Solar panels, for example, can be installed on open deck spaces to harness solar energy, which can then be used to power certain onboard systems. Battery storage systems are also being explored to store excess energy generated during peak production times for use during high-demand periods, reducing the reliance on traditional power sources. By considering the speed of the ship and strategically planning itineraries, cruise operators can reduce fuel consumption, reduce emissions, and contribute to a more sustainable cruising industry.
On the other hand, smaller vessels with fewer amenities and a lower passenger capacity may have lower fuel consumption rates. When it comes to propulsion, the energy required to move a larger ship through the water is inherently higher compared to a smaller vessel. This is due to the increased mass and resistance encountered by the ship. As a result, larger cruise ships consume more fuel to overcome these forces and maintain their desired speed. The difference in fuel consumption between a small cruise ship and a mega-cruise ship can be substantial.
These typical sizes range between 140 to 180 MT of their 85% and above rated loads of fuel consumption. A ship’s fuel consumption depends on several factors varying from its structure to carriage capacity. Meanwhile, cruise liners have only one cargo, with the highest value amongst all, the human life! To approximate an ideal fuel consumption outline, the crew accounts for several changes. Cruise Hive was established back in 2008 and among the earliest blogs in the industry.
Depending on the ship, cruise ships can sail for 10 to 14 days before refueling. However, there are a lot of factors that go into this number, such as size of the ship, number of days spent at sea, and the fuel efficiency of the ship. Size is an essential factor in cruise ship fuel consumption and fuel efficiency.
