How Much Does it Cost to Fuel a Cruise Ship?
Table Of Content
For example, some cruise lines are transitioning to liquefied natural gas (LNG) as a cleaner-burning fuel option. LNG produces fewer CO2 emissions and virtually no SO2 and particulate matter compared to traditional marine fuels. As public awareness and demands for sustainable cruising increase, cruise lines are investing in innovative solutions to reduce average fuel consumption per day.
Types of Fuel Used by Cruise Ships
A cruise ship with a 1 million ton fuel capacity requires nine hours to fully fuel. Running out of fuel is one of the worst things to happen to a cruise ship. For the safety of the thousands of passengers and crew, cruise lines take extra precautions to ensure their vessels have more than enough fuel at all times.

Additionally, cruise operators are adopting measures to manage passenger density and optimize energy consumption onboard. To consume the large amounts of fuel that they do, cruise ships need to be able to hold a lot of fuel – a very large amount. There are no gas stations at sea, so cruise ships need to refuel at the port. While at a port, a small bunker barge approaches the vessel’s side and delivers the right fuel.
How Many Gallons Of Fuel Does A Cruise Ship Use
Cruise lines often analyze various factors, including wind patterns, tidal currents, and sea conditions, to determine the most fuel-efficient routes. The size of a cruise ship and its passenger capacity have a direct impact on fuel consumption. Larger ships generally require more fuel to propel their weight and accommodate the facilities and amenities onboard. In addition to the engine type, onboard operational practices also contribute to fuel efficiency.
Factors That Affect Fuel Consumption
The LNG is stored at temperatures -160 Celsius (-256 Fahrenheit) and under pressure 4-6 bars. In April 2018, the Norwegian cruise and ferry company Hurtigruten announced a USD 150 million fleet renovation project. Almost all vessels will be upgraded with new hybrid powerplants that combine LNG-engines and batteries. The LNG cruise ship concept was first introduced by Wartsila (Finnish manufacturing company) and is based on drive shaft propulsion instead of azipods. The LNG tanks' location is in the upper deck area (right below the funnels). All ships are supplied with emergency generators to maintain vital electrical power.
The Role of Ship Size
To compare, smaller yachts usually carry 200 to 1200 gallons of fuel onboard. 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.

Average Fuel Consumption per Day
In such conditions, their maintenance stoppages will be minimum and with high safety awareness. This indicates that the cruise ship’s load parameter will primarily be a dynamic factor rather than a static one. For safe navigation in such circumstances, the majority of owners always stock their ships with extra bunkers. With a combined crew and passenger count of roughly 1,200 and a total tonnage of 28,388, Fred Olsen’s agile, sleek Boudicca is on the smaller side of things. Boudicca uses less fuel than the majority of liners currently crisscrossing the world’s oceans, traveling at an average speed of 18.5 knots and reaching a top speed of 22 knots. This is leading to increased interest in cleaner fuels like Liquefied Natural Gas (LNG), as well as technologies like fuel cells and battery power for certain shipboard systems.
Cruise Ship Size and Passenger Capacity
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. This storied passenger liner is built for speed and is capable of a cruising speed of 29 knots and a top speed of 32.5 knots.
LNG-powered cruise ships
Hence, once the vessel route comes through, the bunker estimations go underway. 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. Cruise ships primarily stay near the coast, with sporadic excursions into the deep ocean. Passengers’ desire to partake in both onboard and shore entertainment at the same time is a major factor in this.
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. If the engine department has information of rough weather, the same is taken into account for surplus bunkers. 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.
These large vessels can consume up to 50 metric tons (around 13,000 gallons) of fuel per hour, translating to a significant amount over the course of a day. However, it is important to note that the cruise industry is actively working towards reducing the environmental impact of larger ships. This includes exploring technologies to improve fuel efficiency, adopting cleaner fuels, and implementing operational practices that promote sustainability. By considering these factors and implementing fuel-saving measures, cruise ships can reduce their gas consumption and minimize their environmental footprint. From optimizing routes to improving engine efficiency and utilizing alternative fuels, the industry is taking steps towards a more sustainable future for cruise ship travel. We will also look into the future trends in fuel consumption and explore how the industry is working towards reducing its carbon footprint.

Hence, the evolving fuel option produces a cleaner and cost-efficient alternative to the cruise industry. 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.
The new systems and technologies included engine control and monitoring systems, safety and fuel efficiency equipment. Without a source of power, these huge cruise vessels would be nothing more than drifting aimlessly hotels. A large number of older ships use diesel reciprocating engines for generating power for propulsion. Cruise ship engine power is supplied through the transmission to the propeller shafts. Modern ships use either diesel-electric engines or gas turbines as a source of power for propulsion, and for ship's systems.
Instead, they may raise prices on future cruises to compensate for the added fuel expense. Cruise ships require a large amount of fuel to propel the ship forward and power onboard facilities. For these ships to receive regular updates, it’s crucial to keep track of the fuel levels in all tanks.
Usually, ships are powered by four or five generator sets (medium-speed, 500 revolutions per minute), fueled by diesel and creating 8-10 MW energy each. The power density of marine diesel medium-speed engine is 80 kilowatts per cubic meter. Ships that use diesel engines are required to carry exhaust-treatment systems and catalytic-reduction equipment to reduce the environmental impact. Cunard QE2, for example, consumes daily 380 tons of fuel when traveling at 29 knots speed and carries fuel enough to sail for 12 days. Usually, ships fill up at various seaports and use fueling barges as floating gas stations.
