The fuel cost for the Oasis-class vessels is estimated to be around $300,000 per day. The speed at which a cruise ship travels also affects its fuel consumption. Ships that travel at higher speeds burn more fuel per hour than those that travel at slower speeds.

Collaboration among cruise lines, industry associations, and regulatory bodies will establish industry-wide standards and best practices, driving the industry’s commitment to sustainability. If you’ve ever thought about cruise ship fuel consumption, you likely have a lot of questions. Cruise ships are engineering marvels that complete incredible feats — like taking passengers from St. Maarten to Barcelona while they swim, dine and lazily watch the sea pass by. But while guests enjoy life onboard and its many pleasures, the crew keeps the ship fueled and powered behind the scenes. In this post, we’ll answer a few common questions about cruise ships and how much fuel they use.

When a cruise ship is being designed, they consider how the water will affect the ship and consequently affect fuel consumption. In addition to these efforts, the cruise industry is actively participating in industry collaborations and sharing best practices to drive sustainability forward. It is worth noting that the transition to cleaner fuels and new technologies is a complex process that requires investment and infrastructure development. 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. According to Marine Insight, a large cruise ship of 1,000 feet in length uses over 200 metric tons of fuel per day. A medium size cruise ship, holding 1 million gallons of fuel, would take about 285 straight hours of fueling to be maxed out!

In general, a large cruise ship up to 1,100 feet in length can carry as much as two million gallons of fuel on board. For comparison, a private motor yacht between 40 and 60 feet only carries 200 to 1,200 gallons, while something massive like the Exxon Valdez carries up to 55 million gallons.

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.
When sailing, the Spirit chugs along at an average speed of 24 knots and burns approximately 1,100 gallons per hour. Thus, with a fuel capacity of over 350,000 gallons, it can conceivably remain at sea for 12 days without refueling. TUI published the company's environmental impact report (first of its kind) including environmental objectives and TUI strategy for a 5-years period.
More passengers require more energy to maintain a comfortable and enjoyable experience for everyone onboard. Now that you know about cruise ship fuel consumption and how much fuel cruise ships hold, let’s talk about the reason for cruise ship fuel consumption to be so high. Weather conditions, such as wind, waves, and currents, can also affect a cruise ship’s gas consumption.
Cruise lines carefully calculate the fuel needed for each voyage based on the itinerary and plan accordingly to ensure they have enough fuel to reach their destinations. A cruise ship can typically travel for about twelve days without refueling, although most voyages last between 7 to 10 days, rarely requiring the ship to be at sea for its maximum fuel capacity duration. Cruise ships are increasingly using alternative fuels such as liquefied natural gas (LNG), hydrogen, methanol, and ammonia, aiming for 27-30% adoption by 2050 to achieve zero emissions targets.
Most of the world's largest cruise ports have such dockside electrical hookups, reducing bad emissions by up to 95%. The power generated by the main engines/powerplant produces electricity that is used from the propulsion motors, as well as all auxiliary systems and hotel functions. This innovative maritime technology allows the engines to be started and stopped depending on the onboard electricity demand, which additionally improves fuel efficiency.

Cruise lines often analyze various factors, including wind patterns, tidal currents, and sea conditions, to determine the most fuel-efficient routes. Similarly to how your car consumes more fuel the faster it goes, cruise ships burn more fuel when they go fast. For example, an average-sized cruise ship may have engines with a power output of around 30,000 to 40,000 horsepower, while mega-ships can have engines with a power output exceeding 100,000 horsepower. The greater the engine power, the more fuel is required to generate that power, leading to higher gas consumption. A small number of ports around the world have installed infrastructure for cruise ships to connect to the onshore electrical power grid to supply much of the power needed when the ship is docked. This is known as Cold-Ironing, which can reduce emissions from a ship while docked.
It burns cleaner than its counterparts, significantly reducing emissions and making it a friendlier choice for our oceans and the air. Hopefully, you’ve learned more than what fuel cruise ships use and have started to think about the future of cruise line fuel. Liquified natural gas has emerged as a more environmentally friendly alternative energy source for cruise ships. If you’re an avid cruiser, have you ever thought about what type of fuel cruise ships use? 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.
The Promas Lite system (mentioned above) generates cruise ship fuel savings in the range of 5-15% depending on the operation type and the actual performance of the ship's existing propeller. Ship's powerplant includes 4x Wartsila engines (model 8L50DF, total power output 30,4 MW). Propulsion is diesel-electric (2x shafts with fixed-pitch propellers) and wind-assisted (with 1x rotor sail). LNG tanks are two (type C / vacuum insulated), each with capacity 200 m3 and weight 140 tons (LNG weight 85 tons per tank). Promas propulsion integrates propeller, hubcap, rudder bulb and the rudder into a single unit which can increase propulsion's efficiency by 3-8% (1-screw vessels) and by 2-6% (2-screw vessels). It also improves maneuverability, reduces fuel consumption and bad emissions.
Thankfully, cruise ships go through rigorous maintenance before and after trips which gives crew members and mechanics ample time to see that the tanks of cruise ships are full and ready to go. So, the next time you find yourself on a cruise, remember the incredible journey of fuel that powers your experience. It’s a reminder of the seamless blend of adventure and engineering, luxury and logistics, that makes cruising an unforgettable experience.
While at a port, a small bunker barge approaches the vessel’s side and delivers the right fuel. Cruise ships refuel by a small barge, which pumps around 110 tons of fuel per hour. A cruise ship with a 1 million ton fuel capacity requires nine hours to fully fuel.
Liquefied Natural Gas (LNG) is considered a green fuel for cruise ships. LNG stands out as a more environmentally friendly option for cruise ships compared to conventional fuels. Its cleaner-burning nature notably lessens greenhouse gas emissions, thereby substantially lowering its ecological footprint. Having journeyed on both cruise ships and observed cargo vessels, I’ve noticed their starkly different fuel consumption. Cruise ships focused on providing luxurious experiences, have high and varied power needs. They’re like floating 5-star hotels, requiring fuel for everything from lighting to air conditioning, far exceeding the demands of cargo ships.
