While many cruise lines are taking steps towards greener operations, there is still work to be done to achieve widespread adoption of cleaner and sustainable fuel options across the industry. A cruise ship that holds about 1,000 passengers can spend over $15,000 a day on fuel, depending on fuel prices. All ship links redirect to the vessel's "itinerary-schedule-current position" page. "Rotor Sail Solution" is an innovative technology developed by the company Norsepower Ltd (Finland) in 5 years. It reduces fuel consumption and also COx emissions up to 900 tons per year (depending on wind conditions). The ship is powered by a total of five Wartsila dual-fuel engines - three 12-cylinder (model 12V50DF, combined output 34,2 MW) plus two 6-cylinder (model 6L50DF, combined output 11,4 MW).
How Much Fuel Do Cruise Ships Hold?
It’s up to the cruise line’s discretion whether they charge the extra fee. Instead, they may raise prices on future cruises to compensate for the added fuel expense. Let’s check out some other alternatives to diesel that cruise lines are using – both good and bad. For the project was contracted Rolls-Royce Marine, initially for 6 ships plus optional another 3. The project also includes all vessels to be upgraded with shore power capabilities.
Specific Consumption for Energy Generation
Taking steps to reduce fuel consumption and adopting eco-friendly practices are crucial for the cruise industry to minimize its environmental impact. By leveraging technology, optimizing itineraries, and adopting cleaner fuels, cruise lines can continue to improve their fuel efficiency and contribute to a more sustainable future. In this article, we’ll delve into the factors that affect fuel consumption on cruise ships, the types of fuel they use, and the average fuel consumption rates.
Marine steam engines
It’s worth noting that fuel consumption is not solely determined by the distance traveled. Cruise ships often spend a significant amount of time docked at port, where they can connect to a shore power supply and reduce their dependence on onboard generators. However, when at sea, they rely heavily on their engines to maintain a steady speed and power the ship’s systems. The low cost of heavy fuel oil has made it the primary fuel source for marine vessel propulsion – such as cruise ships.

It becomes important for the crew onboard to know the engine characteristics. 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. This will include the port stays, sailing conditions, and carriage capacity too.

The greater the engine power, the more fuel is required to generate that power, leading to higher gas consumption. The size of a cruise ship is often determined by the number of passengers it can accommodate, as well as the amenities and facilities it offers. Larger ships have more decks, cabins, entertainment venues, restaurants, and recreational areas, all of which require substantial amounts of energy to operate. This energy is generated by the ship’s engines, which consume gas to produce power.
All-electric passenger ships
Ships that traverse longer distances or visit remote destinations may consume more fuel than those with shorter routes or frequented ports of call. Additionally, itineraries that involve significant deviations from direct routes or sail against strong currents may also lead to higher fuel consumption. Water purification and desalination systems are another significant consumer of auxiliary power. Cruise ships rely on these systems to provide clean and potable water for drinking, cooking, and other purposes. The energy-intensive process of treating and purifying seawater requires careful management and optimization to minimize fuel consumption. One of the primary contributors to auxiliary power consumption is the lighting system onboard.
For Liquefied Natural Gas (LNG), the process can take somewhat longer due to the complexities of handling this type of fuel. However, the exact amount of fuel a cruise ship needs to filll the tank varies depending on the size of the ship, its engine efficiency, and the length and nature of its voyages. Safety is still crucial because most bunkering takes place prior to departure or during port visits. Additionally, the nature of cruise ships makes them even more aware of the potential risks.
These tanks are not only designed to hold fuel but also have mechanisms to manage the fuel’s temperature and viscosity, ensuring it’s in the optimal state for combustion in the ship’s engines. To better illustrate this process further, consider the Louis, a Canadian icebreaker vessel The ship’s fuel tank has a capacity of about 1 million gallons. A barge will refuel the ship by pumping about 110 tons of fuel into it every hour. Cruise ships typically measure their fuel consumption in terms of “gallons per nautical mile” (g/nm) or “liters per nautical mile” (l/nm). These units represent the amount of fuel required to travel one nautical mile. Several factors come into play when determining the fuel consumption of a cruise ship.

In 2012, TUI used 54,463 tons of fuel, including 9,732 tons LSFO (low sulfur fuel oil), 40,880 tons HFO (heavy fuel oil) and 3,851 tons MDO (marine diesel oil). The average gas consumption of a cruise ship per day can vary significantly depending on numerous factors. These factors include the ship’s size, speed, route, weather conditions, and even the onboard amenities. Despite efforts to improve fuel efficiency, cruise ships still consume a substantial amount of gas on a daily basis. The fuel consumption of a cruise ship is measured in terms of “gallons per nautical mile” (g/nm).
Understanding the factors that impact gas consumption and the environmental implications of this consumption is crucial as we strive for more sustainable travel options. Cruise lines continuously strive to find the right balance between ship size, passenger capacity, and fuel efficiency. By investing in technologies and adopting sustainable practices, the industry aims to reduce the environmental impact while still providing unforgettable experiences for passengers. 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. When it comes to propulsion, the energy required to move a larger ship through the water is inherently higher compared to a smaller vessel.
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. LNG fuel is colorless, odorless, non-toxic, and cleaner than petroleum or other fuels. Since it burns clean, LNG has the power to reduce greenhouse gas emissions significantly and therefore has a low environmental impact. Recognizing the need for environmental sustainability, the cruise industry has been actively working to reduce its environmental impact. Cruise lines are increasingly investing in advanced emission control technologies, such as scrubbers and catalytic converters, to reduce the release of pollutants. These technologies help remove sulfur and other harmful substances from exhaust gases, resulting in a significant reduction in emissions.
Diesel-electric engines, known for their higher fuel efficiency compared to gas turbine engines, can consume less fuel per day. Cruise lines are also exploring alternative fuel technologies, such as liquefied natural gas (LNG), to further reduce fuel consumption and minimize environmental impact. By understanding the factors that affect fuel consumption, such as ship size, speed, and engine efficiency, cruise lines can make informed decisions to improve their operational practices. The use of cleaner fuels like liquefied natural gas (LNG), marine gas oil (MGO), and biofuels can significantly reduce emissions and air pollution. The environmental consequences of cruise ship gas consumption include air and water pollution, oil spills, disturbance to marine life, and coral reef damage.
Thankfully, many cruise ships are turning to LNG (liquefied natural gas) fuel. You might think back to the Louis, the Canadian icebreaker ship we spoke about earlier, as another example of how the environment and weather conditions affect fuel use. When traveling through open water, the Louis burns about 7,925 gallons a day, or 330 gallons per hour. 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. Cruise ship operators continually seek to manage and reduce their fuel costs, which represent a significant portion of their operating expenses.
Lots of voyages had to be canceled, extensive dry-docking periods were required for pod bearings to be replaced, and NCL didn't want to take the risk. When entering service in 2004, the Cunard's QM2 was the biggest in the world at 150,000 GR tonnes. 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.
The new MSC ships have 5400 passengers capacity at double occupancy each. Main engines and generators require electricity and it's needed to keep them going. Pumps that are driven electrically take in cold ocean water to cool the engines and electrical pumps get fuel from fuel tanks and supply it to the engine. Electrical power is vital for many operational functions - without it, ships come to a halt. For stability, the ship's heaviest weights are at its lowest possible deck, and usually, engines are mounted above the keel.
