As for smaller machinery (cabin lights, galley equipment), the electricity goes through the transformer and is thus stepped down into lower voltage. Large cables snake through all the ships to distribute electrical power. They carry power from generators to switchboards, through passageways, public rooms, crew and passenger cabins. If the electrical cables aren't truly redundant, even ships that feature two engine rooms suffer power failure. RMS Queen Mary 2's four main diesel engines are above the keel, with two smaller gas turbines on top-deck (aft of the funnel). However, current maritime legislation requires vessels to have equipment duplication and 2 engine rooms.
Where Is the Engine Room Located on a Cruise Ship?
The ship is powered by a total of five Wartsila dual-fuel engines - three 12-cylinder (model 12V50DF, combined output 34,2 MW) plus two 6-cylinder (model 6L50DF, combined output 11,4 MW). Its propulsion system includes two Wartsila fixed-pitch propellers with twin propeller shafts. Navigation systems are also Wartsila-made, including NACOS Platinum (integrated vessel control system). The next photo shows Celebrity's Solstice-class ship propulsion (the 4 aft azipods, and the underwater hull shape). Wartsila's fuel engine package was specifically designed to reduce fuel consumption.

This data-driven approach allows them to implement fuel-saving strategies and continuously optimize engine performance. Discover these hand-picked articles to learn about the many solutions for future-proof, sustainable cruise ship operations. Many cruise lines have voluntarily adopted the Cruise Industry Passenger Bill of Rights, which debuted in 2013. It's worth noting crew members routinely undergo safety training onboard ships and practice the skills they might need in an emergency situation. The signals emitted by special navigation satellites are picked up by the cruise ship through a special antenna. On board, a computer converts these signals into the exact position of the ship at a given time.
Cruise Ship Engine Power, Propulsion, Fuel
The Promas Lite propulsion future clients, besides passenger ships, are marine vessels like fishing and freighter ships. Decarbonization and digitalization are changing the way we power cruise ships. Our experts can help you find solutions which respond to questions of fuels, emissions, technology, and retrofits. In many cases, the ship will be able to proceed on its own, though at a slower speed. This might require skipping planned ports so the ship can make it to its final port on time. If the engine failure is short-lived and the ship's crew are able to restore power again quickly, the captain might make the decision to continue with the ship's itinerary, as planned.
Not all cruise ports have facilities to enable shore-to-ship energy. But many larger cruise ports have dockside electrical hookups that allow cruise ships to shut off their engines and run on the city’s electrical grid. The technology reduces harmful emissions by up to 95% while ships are docked. Cruise ships like the Oasis-class (Royal Caribbean) contain six engines, while many others have only four. Space is needed not just for engines, but for fuel tanks, generators, engine workshops, and the control room. RMS Queen Mary 2 is equipped with exhaust gas economizers, using waste heat from engines to produce steam.
Future fuels and fuel flexibility
Booking this room may mean you will experience vibrations and noise from the engine. You may hear the crew as they go back and forth to the engine room throughout the day and night. If you are in the engine room while the engine is running, it will still be very loud regardless of what noise-reducing technology is used. To put it in perspective, those who enter the room are required to wear hearing protection. The decibel range for the engine of a standard cruise ship exceeds 173 decibels. This is extremely loud and within a range that can damage hearing in seconds.

The main job of the Officer of the Watch is to monitor the ship’s systems and surroundings, and to ensure that everything is running safely and smoothly. During extreme weather, docking, or other special cases, the Captain of the ship is also present on the bridge to guide the deck officers. The main reason people select an inside cabin on a lower deck is that they are less expensive. Additionally, what most people don’t know is that if you book a cabin near the engine room, you may have the option to upgrade. This makes the chips more efficient, powerful and environment-friendly than their predecessors.
Hurtigruten's Roald Amundsen is perhaps the best known example; the ship has extensive battery packs that will have enough stored power to operate and sail the ship, even with the main diesel engines shut down. Newer cruise ships have a large gap between the cruise ship engine room and passenger cabins to minimize noise and vibrations. Many of today’s diesel-engine cruise ships also employ a shaft generator to generate electricity for shipboard services, like lighting. Modern diesel-powered cruise ships have between four to six medium-speed (500 revolutions per minute) engines. Each engine can generate upwards of 25,000 horsepower or nearly 18.5 megawatts.
This ensures that the selected engines meet the unique operational requirements of the cruise ship while adhering to safety and environmental standards. Wärtsilä’s expertise covers the full spectrum of solutions and services, from cruise ship engines to digital solutions and from hybrid ships to lifecycle services. Cruise ships can stay productive and competitive – and on the steady course towards net zero operations. It reduces noise and keeps the heat generated by a fully operating engine from coming out on adjacent decks.
Various factors influence these power requirements, including the ship’s size, weight, intended speed, and onboard facilities. Cruise ships require significant power to propel the vessel and operate numerous systems and amenities. While gas turbine engines offer several advantages, they also have some considerations to take into account, such as higher fuel consumption at lower speeds and the need for regular maintenance. However, ongoing advancements in gas turbine technology continue to improve their efficiency, reliability, and environmental performance. Gas turbine engines, also known as jet engines, are another type of engine used in cruise ships. These engines operate on the principle of burning fuel to produce high-pressure gases, which then flow through a turbine to generate power.
Determining the type of engine that is installed on a new cruise ship involves examining the engine’s size. 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. The cruise industry began in 1844, when ships were propelled by steam engines, performing the driving of propellers by using steam as working fluid.
In addition to propulsion, the power requirements for onboard facilities and amenities must also be taken into account. Cruise ships have a wide range of facilities, including restaurants, bars, entertainment venues, spas, and more. These facilities require electricity and other energy sources to operate smoothly.
