Cruise Ship Engine, Propulsion, Fuel Consumption
Table Of Content
Through technological advancements, operational strategies, and a focus on sustainability, cruise lines are continuously working towards a more efficient and environmentally responsible future. By embracing innovative solutions and addressing the challenges of fuel consumption, the industry can ensure that cruising remains a sustainable and enjoyable experience for generations to come. In recent years, there has been a shift towards slow steaming in the cruise industry. Slow steaming refers to reducing the cruising speed to achieve fuel savings. By operating at a lower speed, ships can optimize fuel consumption and decrease emissions. While this approach may extend the duration of the voyage slightly, it can have a positive impact on fuel efficiency and environmental sustainability.

These factors are so crucial that virtually no two cruise ship sailings will cost the same to fuel. When considering how much it costs to fuel a cruise ship, you must also consider the factors that determine this cost. Let’s check out the factors that largely affect how much it costs to fuel a cruise ship. As you can imagine from their size, the cost of running a cruise ship is significant.

Factors Affecting Fuel Consumption
Now, she helps over 1 million people per month to plan their perfect cruise holidays. However, actual costs could be higher or lower, given that LNG prices can also vary widely, influenced by factors like regional availability, demand, and the costs of storage and transportation. If LNG costs, for example, $4 per gallon, the cost to fill the same-sized ship would be over $5.3 million.
How Much Fuel Does a Cruise Ship Hold?
A traditional tanker or bulk carrier has long-distance voyages with steady speed. These values range between 12 to 14 knots, with delivery dates and design considerations being important. Meanwhile, sailing on the coastal edges mostly uses eco or low-speed movement. This means a balance of speed variation limits the excessive burning of fuel. It also makes sure the vessel complies with the emission regulations within the region.

If you want to impress your friends with fun cruise ship statistics, the average cruise ship uses 18.3 gallons of fuel per minute or 1100 gallons of fuel per hour. The fuel supply in the ports they visit is crucial to any owner or operator of an oceangoing ship, like a cruise ship carrying passengers. The California Air Resources Board (CARB) reports that there are over 400 ports worldwide that sell marine fuel.
Fuel Consumption of Cruise Ships
The sheer size and weight of cruise ships make their gas consumption substantial, and they use a considerable amount of fuel to power the engines that propel them through the water. It’s important to note that while these factors influence fuel consumption, cruise lines are actively exploring ways to mitigate their impact. Environmental regulations and industry initiatives are driving the adoption of cleaner and more sustainable practices, encouraging cruise operators to improve fuel efficiency and reduce carbon emissions. 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.
According to Marine Insight, a large cruise ship of 1,000 feet in length uses over 200 metric tons of fuel per day. The cost to fuel a cruise ship depends on several factors, including fuel type, cruise ship size, and storage. Although there are many different cruise ship size classifications, large ships are typically defined as those that can accommodate more than 2,500 passengers. Approximately 1,500 passengers can board a medium-sized ship, give or take.
Specific Consumption for Energy Generation
One option is to make them bigger and more effective when maneuvering, another is to add additional mini-pods or install full-sized pods.

The blended oils and the VLSFO fuel have significantly less density, making its volume go higher. Hence, the bunkering team takes consideration of the same while fueling estimations.
Some of the larger ships depend on two power sources - one for electrical power and one for propulsion. 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.
Despite the challenges, the cruise ship industry is gradually moving towards cleaner, more sustainable fuels in response to growing environmental concerns and regulations. Other cruise ships use Marine Gas Oil (MGO), especially in environmentally sensitive areas like the Arctic, where cleaner fuel use is mandated. Cruise ships primarily use a type of fuel called Heavy Fuel Oil (HFO), a residual product from the crude oil refining process, which is cheap but highly polluting. Some newer ships are powered by Liquefied Natural Gas (LNG), which is cleaner but more expensive.
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. Itineraries that involve longer distances or require the ship to navigate against strong currents can increase fuel usage. Alternatively, routes that take advantage of favorable currents or strategic sailings can help conserve fuel.
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). This metric provides an indication of the ship’s fuel efficiency and can vary depending on the ship’s design, technology, and operational factors.
The Harmony, a Royal Caribbean ship, has two 16-cylinder Wärtsil engines that are four stories high, according to The Guardian. They would consume approximately 66,000 gallons of highly polluting diesel fuel per day when operating at full capacity, or about 1,377 gallons per hour. It’s important to remember that Harmony of the Seas was the largest cruise ship in the world up until the new Symphony of the Seas debuted in 2017.
These systems are essential to maintain a comfortable environment for passengers and crew, particularly in warm climates. Cruise operators employ advanced HVAC systems with energy-saving features, such as variable speed pumps and optimized temperature controls, to reduce power consumption while ensuring passenger comfort. Any ship transporting thousands of people and operating as a mini city requires significant power. That said, cruise lines are always aware of their ships’ fuel usage and fuel efficiency and finding ways to improve them, such as using LNG to power cruise ships. 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.
The changing propulsion design and source decide how much fuel does a cruise ship use. The cruise ship draughts have a lesser variation in comparison to the cargo ships available. Hence, the load parameters do not necessarily depend on it but rather the weather conditions.
