The more surface there is for the air to hit, the more drag it creates. Such a car has an easier time reducing drag and “slipping” through a wall of air. An aerodynamic vehicle also has less trouble accelerating on a very windy day than a car with a bulkier design. As a result, the engine doesn’t have to struggle to push through the air and will use less fuel to ride.

Meanwhile, like their larger sisters, the medium-size cruises also have manoeuvring requirements. Most electric propulsion cruise ships have a twin-screw or triple-screw propeller design. Some cruise lines add a fuel surcharge to their cruise fare, which you’ll see when you book your ticket in times of high fuel prices. However, for the most part, the cruise ship’s fuel is not something you have to worry about on your vacation.

Ship Size and Construction
Indeed, the demands of a cruise ship are extraordinary and so is the fuel consumption. Of the many fascinating questions cruise ships inspire, the most common is how much fuel they use. Furthermore, cruise lines are committed to waste management and implementing sustainability initiatives onboard.

Battery power is used during turnaround navigation in ports when the onboard diesel-electric generators are switched off. As of 2019, Corvus Energy delivered its innovative product line "Orca ESS" to 200+ vessel conversion/upgrade projects, totaling 200+ MWh. In May 2019, the US company "Maid of the Mist" ordered ABB two new all-electric vessels for the company's Niagara Falls tours. Both catamarans are 100% emission-free being powered by high-capacity batteries.
One to two million gallons of fuel could fit on a large cruise ship with a length of 900 to 1,100 feet. A 440-foot-long ferry, for example, might carry about 130,000 gallons of fuel, whereas a massive ship that is over 1,300 feet long can carry over 4 million gallons. The largest Windstar ships are less than 600 feet long, so as you might expect, they use a lot less fuel than a typical cruise ship. In the next section, we will explore the technologies employed by the cruise industry to enhance fuel efficiency and minimize its environmental impact.
Cruising speed is also another factor that you must take into consideration. Larger cruise ships require more fuel to reach certain speeds due to the power needed to propel the vessel forward. Size is an essential factor in cruise ship fuel consumption and fuel efficiency.
What kind of fuel do cruise ships use?
While mechanical propulsion is optimized for a single-speed, electric propulsion is based on rotating speed control resulting in energy efficiency at all speeds. ABB's propulsion also improves passenger comfort as the ship runs much more quietly and smoothly. ABB's Octopus marine technology allows real-time monitoring of the vessel's energy (and fuel) consumption. Based on the collected data, the software suggests optimal performance recommendations.
In addition to the engine type, onboard operational practices also contribute to fuel efficiency. Cruise operators can implement measures such as optimizing engine load, improving hull design for better hydrodynamics, and scheduling maintenance to ensure engines operate at their peak performance. Regular monitoring and analysis of fuel consumption data can help identify areas for improvement and guide fuel efficiency initiatives. These are rough estimates and actual fuel efficiency can vary based on many factors. These can include the ship’s size, speed, and load, the sea and weather conditions, and the efficiency of the ship’s engines and other systems.
Diesel engines are the traditional type of engines used, but a diesel engine typically consumes a lot of fuel. Moreover, a larger vessel needs larger engines, which will consume more fuel. Keep reading to learn everything about cruise ship fuel consumption and more. Any large ship, like a cargo ship or container ship, will consume a significant amount of fuel, and cruise ships are no exception. If these are questions you commonly have onboard your cruise, you’ve come to the right place to find answers.
So, let’s dive in and explore the astounding world of cruise ship fuel capacities.. Monitoring of fuel levels across all tanks is important for these ships for regular updates. In addition, the hectic nature of work and safety aspects need mandatory remote gauges on each tank. All these gauges direct back the readings to the control room for the engine crew monitoring ability.
The next photo shows Celebrity's Solstice-class ship propulsion (the 4 aft azipods, and the underwater hull shape). The 3rd Oasis-class ship - Harmony of the Seas, is currently the most technologically advanced and energy-efficient cruise vessel ever built. 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.

In addition to spills, routine operations like ballast water discharge and sewage discharge can also introduce pollutants into the water. Beyond that, much like cars, the design of the cruise liner also dictates how much fuel will be consumed. When a cruise ship is being designed, they consider how the water will affect the ship and consequently affect fuel consumption. 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.
According to the College of Engineering and Applied Science at the University of Colorado Boulder, a large ship might consume up to 250 tons of fuel per day. To put that in perspective, that’s equivalent to over 80,000 gallons of fuel a day. Regular-sized ships, by contrast, may use up to 150 tons of fuel per day. In recent years, there has been growing concern about the environmental impact of cruise ships and their fuel consumption.
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. One of the primary contributors to auxiliary power consumption is the lighting system onboard. Cruise ships are equipped with numerous lights throughout the vessel, including cabins, public spaces, theaters, and restaurants. Traditional lighting systems, such as incandescent bulbs, consume a significant amount of energy.
