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. 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. The cruise ship engine power is responsible for driving propellers, and the other possibility is producing electricity that is used subsequently to drive propellers. The engine's effectiveness depends not only on the design but also the ship's shape, weight, and size. Power is measured in horsepower traditionally - one horsepower equals 746 watts.
Specific Consumption for Energy Generation
Cruise ship fuel consumption is influenced by vessel size, speed, itinerary, onboard facilities, and propulsion systems. In this article, we will delve into the fascinating world of cruise ship fuel and explore how much fuel these massive ships actually hold. We will examine the factors that affect fuel capacity, the types of fuel used, and how it is stored on board.
Fuel Consumption of Cruise Ships
Hence, the power generation fuel requirements onboard cruises are almost 10 times a standard bulk carrier. This also includes auxiliary services like steam generation and boiler operations. On average, these vessels go from 7.5 MT to 20 MT during the port stays. The significant difference also includes the passenger behaviour of visiting the shores, resulting in lower power usage. After the arrival of 0.5%, sulfur content regulation under MARPOL, diesel engines faces significant changes.
Another way to express this is to say that the ship consumes approximately 14 gallons of fuel for every mile it travels. It’s important to understand that a ship’s fuel tank isn’t a single giant container, but usually a complex system of tanks located in different parts of the ship. This distribution helps maintain the balance and stability of the ship. A large cruise ship, such as Royal Caribbean’s Harmony of the Seas, can carry approximately 1.33 million gallons (approximately 5 million litres) of fuel. However, the infrastructure for LNG refuelling is not yet widespread, and the fuel itself is more expensive than HFO, making the transition challenging for the cruise ship industry.
How Much Fuel Does a Cruise Ship Use Per Passenger?
It takes over half a day to fully refuel a cruise ship due to its high maximum capacity, energy requirements, and the necessary labor. Because of this, a luxury vessel will seldom pass up the opportunity to refuel at the port. There’s no better time than while the cruise passengers are enjoying the local environment. When cruise ships make stops at ports worldwide, it’s the perfect time to refuel and check the vessel’s condition. However, with cruises being as wide as Royal Caribbean’s Wonder of the Seas at 210 feet long, it isn’t as simple as pulling up to the shore.
Gas-turbine cruise ship power system
Most of the world's largest cruise ports have such dockside electrical hookups, reducing bad emissions by up to 95%. Added to the dual-fuel engines, the new technology makes Viking Grace one of the world's most environmentally-friendly passenger ships, operating with very low levels of emissions and noise. Norsepower's wind propulsion system was also installed on VIKING LINE's newest vessel (still unnamed) scheduled for delivery in 2020. The China-built ferryboat is equipped with two Norsepower-produced rotor sails, doubling its wind power potential. 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.
How much does it cost to fill a cruise ship with fuel?
Efficient fuel storage practices are essential for the smooth and safe operation of cruise ships. The fuel capacity of a cruise ship is influenced by various factors that determine the amount of fuel it needs to carry. Understanding these factors is essential in managing the logistical challenges and operational efficiency of fueling these massive vessels. It’s important to note that the fuel capacity of a cruise ship is not fixed and can vary depending on the specific ship and its operational requirements. Cruise lines closely monitor fuel consumption and adjust refueling schedules accordingly to ensure smooth operations throughout the voyage.
Factors Affecting Fuel Capacity of Cruise Ships
Her small size and average speed of 24 knots consume 1,100 gallons of fuel per hour, which makes her very fuel-efficient. She can stay at sea for an average of 12 days before needing to return to port for fuel. The Cunard Queen Mary 2, hailed as the world’s fastest cruise ship, has a total fuel capacity of 4,381 metric tonnes. This moves the 151,400-tonne luxury liner forward at a rate of 41 feet for every gallon. This allows her to spend 10 days at sea without refueling at her average speed of 29 knots. If she were traveling at her top speed of 32.5 knots, she would reach her destination faster but would use a lot more fuel.

Other manufacturers have their sights set on LNG-fueled cruises in the future. Royal Caribbean’s Icon of the Seas will be its first luxury vessel with sustainable power. The company plans to pad its new Oasis of the Seas line with as many LNG cruises as possible. If you’ve never seen one in port, be prepared to be taken back by the sheer size.
It powers the air conditioning systems, lights and all other appliances aboard the ship. Most vessels produce the electricity they need by using diesel engines. HFO (heavy fuel oil) is used by diesel engines, while MGO (marine gas oil) is used by gas turbine engines. The environmental impact of fuel consumption on cruise ships is a topic of growing concern in today’s world.
With the same distance, a smaller ship will have less fuel consumption than a larger ship, similar to motor vehicles on the road. Cruise ships use either gas turbines, diesel-electric or diesel engines for propulsion and electric power. With this type of engine, the diesel fuels the pistons and crankshaft, which attaches to the propeller and ultimately moves the ship forward. Any operator of an ocean-going vessel, such as a passenger cruise ship, relies on the fuel availability at the ports where they travel.
The first company that fitted cruise vessels with gas turbines, was Royal Caribbean. Gas turbines are greener than diesel engines and allow ships to sail with reduced inventory and smaller maintenance crew. Gas turbines drive generators which in turn provide electricity to propeller motors. They recover heat from gas turbines' exhaust, which then is used to produce the electricity needed for onboard services (air conditioning, water heating). The size of a cruise ship plays a crucial role in determining its fuel capacity.
The longer the ship’s sailings, the more fuel it’ll be required to hold, as cruise lines would want to keep refueling stops during the cruise to a minimum. According to Marine Insight, a large cruise ship of 1,000 feet in length uses over 200 metric tons of fuel per day. A cruise ship that travels short distances, spending most of the day in port, won’t need to refuel as often as a ship that spends seven days sailing across the Atlantic Ocean. Fuel for cruise ships is one of the highest operating costs for the cruise line. By some estimates, up to 20% of a cruise line’s expenditures are fuel related.
Hence, once the vessel route comes through, the bunker estimations go underway. In the article, we discuss the consumption figures of these modern luxury sailing hotels. Moreover, we also consider the changes in the propulsion technology affecting fuel consumption and storage. The primary requirement of these cruise vessels is passenger safety and engagement. In such conditions, their maintenance stoppages will be minimum and with high safety awareness. For the project was contracted Rolls-Royce Marine, initially for 6 ships plus optional another 3.
Today cruising is one of the most popular vacations, but there are significant environmental downsides. Mega-ships burn the dirtiest fuel in the world, even if they are sitting in port. Asthma, cancer, respiratory illness, heart disease, are the results of burned in ports nasty bunker fuel. "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). In comparison to pipeline gas, LNG is superior in quality - purer, with more methane and other energy content.
