Azipod cruise ship propulsion system is situated outside the hull in the aft of the ship. Azipod turns in all directions (360 degrees) by a rudder, providing thrust in any directions, not possible for conventional systems. The biggest ships like Royal Caribbean’s Oasis-class ships have six engines and most other cruise ships have four. The standard cruise ship engine can have a decibel range that exceeds 173 decibels. This is frighteningly loud and well into the range in which hearing damage occurs quickly.

Most major cruise lines organize guided tours of the ship for a small group. Lasting one to four hours, these tours may cover the bridge, galley (kitchens), laundry, recycling, engine control room, backstage of the theater, the mooring deck and the crew's mess hall. Some tours include drinks, snacks, lunch or a take-home souvenir. You might also meet a captain and officers, chief engineer, head chef or hotel director. 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.
Royal Caribbean Quantum-class cruise ships propulsion
This is an older ship, and Promas Lite was the perfect choice as it is a combined "propeller-rudder" system increasing the efficiency of older passenger vessels with lesser tonnage. The upgrade significantly reduced Hurtigruten's operating costs on this vessel. The improved propeller efficiency was estimated to be between 11-14% at a cruising speed of 15 knots (17 mph / 28kph). In April 2012 ABB made a USD 60-million contract to provide the Azipod propulsion systems for the new Royal Caribbean ships of the Quantum-class (Quantum, Anthem, Ovation) and Quantum Plus-class (Pulse, Passion).
Where Is the Engine Room Located on a Cruise Ship?
From Broadway-style shows to live music performances and themed parties, there’s never a dull moment on a cruise ship. Passengers can immerse themselves in various activities and events tailored to their interests, ensuring an unforgettable vacation experience. When visiting the engine room, it’s essential to set realistic expectations to fully enjoy the experience.
How much fuel do cruise ships use?
Now that we are all grown up, Grandpaw’s gadgets are old news, but there is still a place or two on a cruise ship that remains like a pie in the sky for all of us obsessed by ships. 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. Some people argue that most people don’t spend much time in a cabin – they are too busy exploring the cruise ship. There is plenty to do onboard, and if you enjoy the social scene, you may not spend much time inside the cabin other than to sleep.
They are also responsible for drills related to safety, security, pollution prevention and also related shipboard training of the crew-members. Onboard workshops are also a fantastic way to explore new areas of interest and develop new skills. From cooking classes to photography workshops, these interactive sessions offer passengers the chance to learn from professionals and engage in creative endeavors. Before embarking on the tour, a safety briefing is usually conducted to ensure that visitors are aware of any potential risks and how to navigate the environment safely. This briefing may cover important aspects such as emergency protocols, necessary safety gear, and areas to avoid.
Guided Tours
For the purpose of this article, "main engines" refer to those engines that produce the vast power to move the ship. On conventional, or direct drive, diesel vessels, these engines are connected to the propeller shaft; on diesel electric ships, the main engines are connected to the main generators. This type of engine provides enough electricity to move the ship’s propellers and power the cruise ship’s appliances, lights, air conditioning, etc. Most ships will contain several engines connected to their generator. Of course, these shaft generators can only be used when the ship is moving at sea with a fairly constant speed; if the propeller shaft isn't turning, then neither is the generator, and no electricity can be produced. Cruise companies employ new technologies in order to reduce fuel consumption.

For its LNG-bunkering operations in Florida (at homeports PortMiami and Port Canaveral), CCL-Carnival partnered with Royal Dutch Shell plc as fuel supplier for the liners Mardi Gras (2021) and Celebration (2022). After Norwegian Spirit (the first ship in NCL fleet with installed Promas Lite in 2011), in May 2014 the Star Cruises ship SuperStar Virgo became Southeast Asia's first passenger liner with RR's Promas Lite propulsion. Fincantieri used Promas Lite propulsion for all Viking Ocean liners.
It’s important to note that due to capacity limitations, the number of engine room tours available may be limited. Therefore, it’s advisable to secure your booking at the earliest opportunity to avoid disappointment. Even though you may not see much of the hull as a passenger, it plays a massive role in allowing you to enjoy any cruise vacation. For the project was contracted Rolls-Royce Marine, initially for 6 ships plus optional another 3. The project also includes all vessels to be upgraded with shore power capabilities. The above photo shows Oasis-class ship propulsion Azipods (2 units) before being mounted onto the hull.
Each watchkeeping team also has certain assigned machinery under their responsibility. For example, one watch may be responsible for fuel oil system and purifiers, another may be assigned boiler & compressors, and the third may be in charge of freshwater generators and water treatment. The Medical department typically has 3 to 4 doctors and a similar number of nurses who work in shifts. They cater to both passengers and crew requiring medical assistance, at separate timings during the day. They are also the first responders for any medical emergency onboard. The guest services department is the interface between the guests and the ship staff/crew.
Gas-powered ships are faster, but most cruise ships don’t travel faster than knots. Cruise ship fuel tanks are also on the lower decks, but they are kept separate from the main engines. If the waters are calm, cruise ships are safely towed to a nearby shore. In rougher seas, other options may need to be considered for the safety of those on board.
In May 2015, Wartsila Corporation and Carnival Corporation partnered to optimize cruise ship engine room operations of all 101 ships across the corporation's 9 brands. The deal was signed by Micky Arison (Carnival's Chairman) and Bjorn Rosengren (Wartsila's President and CEO). The plan included installing Wartsila's latest marine solutions, first tested on several Carnival Cruise Line vessels in pilot projects. The new systems and technologies included engine control and monitoring systems, safety and fuel efficiency equipment. 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.
It permits luxuries onboard like electricity, plumbing, and air conditioning to function. If you book a cabin near the engine room, you can expect to hear some noise and feel the vibrations caused by the engines. However, cruise ships use sound-dampening technology and insulation to minimize noise pollution. But due to the size constraints, they can’t produce the same power as the main engines and cannot propel the ship.
This acts as a water-tight barrier between the hull’s metal surface and the surrounding water. The hull’s outer plating composes the most visible layer of the hull. It protects the lower portions of the ship and provides the primary defense against external elements, like water pressure and floating objects. In most cases, this plating is made from hardened steel and coated with specialized paint that can withstand the corrosive effects of ongoing saltwater exposure. Wartsila Marine technologies aim to optimize ship performance, but also allow to locate deviations from normal parameters of equipment and engines.
The pistons were connected to a crankshaft, which turned the vertical motion of the pistons into a rotational movement. The crankshaft was directly connected to the propeller through a long propeller shaft. The faster the pistons on the engine moved up and down, the faster the propeller shaft turned and the faster the ship went. In exceptionally rare instances, engines may be placed somewhere other than the very bottom of the ship; on Cunard's Queen Mary 2, the four diesel main engines are located above the keel. However, its two smaller, lighter gas turbines are located at the very top of the ship directly aft of the funnel. Sitting contentedly on deck, listening to the hushed splash of the sea as it washes along the side of the hull, you would be forgiven if you forget you are on a monster of engineering.
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. The engine rooms on cruise ships are located on the lower decks, between the midship and the aft. The engines aren’t quite at the back of the vessel but closer to midship.
