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). If you’re looking for an outstanding cruise ship cabin that’s as quiet as possible, it’s important to know where the engine room is so that you can stay well away from it. 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.

As mentioned, the engine does make vibrations while it operates. They can be felt in the surrounding areas, including cabins that are adjacent to them. It may cause coat hangers to rattle or other items in the cabin to shift, which may disturb your rest.
How Big is a Cruise Ship Engine?
It takes numerous engines to move something that is so massive in size and weight. Combine that with the horsepower required to make it move, and you also appreciate the cruise ship’s knots. Generally, engine failure only generates a brief interruption before it’s fixed. Cruise lines will never jeopardize the safety of guests nor put them at risk if the cruise ship is unsuitable for sailing. In newer cruise ships, engines are found on the lower decks toward the aft. They are not completely to the back of the boat but are found in the mid-aft.

How Does a Cruise Ship’s Engine Work?
The motor is inside the sealed pod and connected to the propeller. Staying in one of these cabins means that you will likely be exposed to plenty of noise and vibrations from the engine. You’re also likely to experience noise from the crew as they go to and from work throughout the day and night.
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. Thanks to proper insulation and sound-reducing features, it won’t sound that loud. Ever wonder what a cruise ship engine room looks like and what it holds?
Ships that do use this type of power have usually solar panels affixed to their exteriors. When ships come into port, they take the opportunity to fill up the fuel tanks. Fueling barges will come up to the ships and load the fuel onboard. When the passengers return from their excursions, the ship is ready to move on. The electricity generated from the diesel-electric method can also be used onboard.
Cruise Ship Engine Power, Propulsion, Fuel
When entering service in 2004, the Cunard's QM2 was the biggest in the world at 150,000 GR tonnes. Her designer Stephen Payne showed the advantages of pod-propulsion giving vessels increased maneuverability. The propellers (screws) of the QM2 ship are mounted on the pods which rotate 360 degrees and provide advanced maneuverability. He made the choice to put pods - though relatively new and yet untested for big ships.
What Are the Cabins in this Location Like?
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. These cabins are in the lower deck and in the middle of the ship. Rooms located in the center of a ship generally don’t contain the luxury of windows, so it may make people feel claustrophobic. Ships that are equipped to use auxiliary wind power have a special rotor sail on deck that uses the direction of the wind to create a force to keep the ship moving forward.
ENGINE Room Tour (Behind the Fun)
However, cruise ships use sound-dampening technology and insulation to minimize noise pollution. In the past, cruise ships kept their engines running while docked to generate electricity for shipwide services. Carnival Cruise Line announced the first LNG-powered vessels in 2015, using a “dual fuel” design. The ships can burn both liquified natural gas and marine fuel, reducing the required fuel storage space.
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.
We only have two sea days, and I didn't want to hog the last sea day alone on a tour. (rest of my family doesn't want to go) I love stuff like this, and it's my first real cruise. Having a picture taken with the captain and getting a picture with everyone on the tour at the bow of the ship was really cool too. When we examine the sheer size of mega-ships, the fact that engines and engine rooms are built so large is understandable. 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.
Another experiment is LED lighting, using less energy and producing less heat (thus is reduced the demand for electricity and air conditioning). Celebrity Solstice-class vessels have solar panels' field over the AquaSpa pool area. This not only provides shade for the pool area but produced by solar panels electricity is used to decrease the electricity demand from the engines. The next photo shows Celebrity's Solstice-class ship propulsion (the 4 aft azipods, and the underwater hull shape). 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.
Aside from housing generators and engines, pumps and heat exchangers are located here to cool the engine and stabilize motors and fins, in addition to the bow thruster system. Since equipment depends on electricity, modern ships contain backup generators on the outside of the main engine room in the event of a fire. As the world considers the effects that fossil fuels have on climate change, cruise ships have come under increasing scrutiny.
To this class belong HMS Queen Elizabeth (2017-commissioned) and HMS Prince of Wales (2019-commissioned), each of them with a total power consumption of 80 MW. The Promas Lite propulsion future clients, besides passenger ships, are marine vessels like fishing and freighter ships. It’s not as if cruise ships lack entertainment when out to 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.
It reduces noise and keeps the heat generated by a fully operating engine from coming out on adjacent decks. On a cruise ship, this is very important, where comfort is one of the cruise line’s top priorities. Ships sail to ports around the world, bringing thousands of people in for the day.
Safety is of utmost importance on any cruise ship, and the engine room is no exception. As the heartbeat of the vessel, the engine room is a highly controlled environment that requires strict adherence to safety measures. With high temperatures, noise levels, restricted zones, and complex equipment, it’s essential to understand the precautions in place for those wishing to visit this vital area of the ship.
