Rather than steam, the ignition of diesel fuel pushes the pistons up and down, turning the crankshaft attached to the propeller shaft. For example, one person may be responsible for the freshwater generators and water pumps and another for the fuel oil systems. All ship links redirect to the vessel's "itinerary-schedule-current position" page. The cylindrical rotor sail has a height of 24 m (79 ft) and a diameter of 4 m (13 ft). The technology is based on the "Flettner rotor" (patented by Anton Flettner in 1922) and uses the so-called "Magnus effect" - the spinning rotor (rotating cylinder) drags airflow faster around one side.
Diesel-Electric Cruise Ship Engines
Regular maintenance by the chief engineer is conducted to make sure that they are running in top condition and to prevent any mishaps while at sea. When it comes to cruise ships, the typical engine is a two 16-cylinder Wartsila 16V 46D which is a common rail engine. They also use three 12-cylinder Wartsila 12V 46D engines to power the ship. Passengers will never see the magnitude of a cruise ship’s engine.
How Loud Are Cruise Ship Engines?
These cruise ships not only comply with emissions regulations but also demonstrate a proactive approach to reducing their carbon footprint. Cruise ship operators are also exploring other sustainable technologies, such as hybrid electric systems. These systems combine traditional engines with electric propulsion, allowing ships to operate on cleaner, electric power during certain parts of the journey.

After that, the gas is cooled (in a vacuum chamber) and liquefied. Then Heat exchangers cool the carrier fluid to temperatures around 20 C / 68 F. The next photo shows Celebrity's Solstice-class ship propulsion (the 4 aft azipods, and the underwater hull shape).

Whether you are curious about a cruise ship’s engine or simply want to avoid the cabins surrounding this noisy area, an engine room can be an interesting place. Ever wonder what a cruise ship engine room looks like and what it holds? Power cables from the HV switchboard connect to the PEM in a conventional DE propulsion system, which converts the electrical power to mechanical power. It then gets transmitted to the propellers with the help of lengthy shaft lines, bearings and thrust blocks. Cruise Hive was established back in 2008 and among the earliest blogs in the industry. Since the start, it's been our aim to provide the latest cruise news covering all the major cruise lines.
While connected to a generator, the engines can run at their most efficient settings regardless of the travel speed. Whether the ship is sailing at 10 or 20 knots, the engines can operate a peak efficiency. The boiler produced steam which created pressure in a pressurized system. When the cruise industry began in the mid-1800s, vessels were propelled by steam engines.

Are third in the same will class will also be constructed, with delivery in 2026. “The first main engine start on a ship largely tells a lot about the ship’s readiness. It is a sign that the various departments throughout the yard have achieved something significant. To achieve this milestone, all professional groups are needed, and for that, big thanks to everyone! The engines are turned on for the very first time on Royal Caribbean's first-ever Icon-class mega-ship at the shipyard. Many cruise lines have voluntarily adopted the Cruise Industry Passenger Bill of Rights, which debuted in 2013.
Ultimately, it's the ship's captain who decides whether to disembark passengers at sea. There are loads of things to do and staying in your cabin will probably be the absolute last thing on your mind for anything other than brief periods of sleep. Perhaps you’re fascinated with the engines that power a cruise ship, or perhaps you want to know which cabins to stay well away from, due to the noise and vibrations of the engine. Reliability and safety play crucial roles in engine selection, ensuring continuous operation, passenger comfort, and crew safety. Cruise ship engines undergo rigorous certifications and adhere to international safety standards.
How much fuel do cruise ships use?
The same way works diesel-electric engines, yet they use a direct drive system, not a turbine. The output shafts, to produce electrical power, are connected to generators. Overall, gas turbine engines provide an efficient and powerful option for cruise ships, particularly those focusing on high-speed travel. Their ability to quickly respond to power demands and lower emissions make them a valuable choice for enhancing the overall cruising experience. These backup generators are always located higher up and outside the engine room spaces to insulate them from fire or damage to the engine room. Big ships require so much power that they might have two or more emergency generators.
If your cabin is towards the bow, you may be awoken by the sound of the anchor being raised and lowered. Or, if your room is by the elevator, you may hear lots of other guests chatting as they stagger to bed in the early hours of the morning. You can target a cabin near the engine room and sign up to be upgraded in the case of last-minute cancellations and it won’t cost you a single dime. There’s also a hidden advantage that those new to cruising probably never consider. You can purchase a cabin that’s near the engine room for an outstanding price, with the option to upgrade.
LNG technology also advances due to IMO's future maritime emissions regulations, especially in ports and while operating in environmentally sensitive destinations. Diesel engines are commonly used in cruise ships due to their efficiency and reliability. They provide the necessary power for propulsion and onboard systems while ensuring fuel economy and compliance with environmental regulations. Gas turbine engines offer high power output and quick response, making them suitable for high-speed cruise ships. Combined Gas and Steam Turbine Engines (COGAS) provide efficient power generation and improved fuel economy by utilizing waste heat to produce steam.
The primary advantage of diesel electric systems is efficiency; they allow the engines to operate near their most efficient settings regardless of whether the ship is moving at 5 knots or 20 knots. On some smaller and midsize ships, such as National Geographic Explorer or Windstar's Star Breeze, Legend and Pride, the concept has not changed dramatically. The mechanics are the same; the main difference is how the power is created. Instead of steam making the pistons go up and down, the ignition of fuel now creates pressure and pushes the pistons up and down, turning the crankshaft connected to a propeller shaft. Despite the colloquialism of "steaming to St. Thomas," the days of steam engines in ships have all but disappeared.
