Beneath the Surface: Exploring the Cruise Ship Hull
Table Of Content
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. Rather than having a large room filled with all the different machinery that keeps the ship moving, the engine components are divided up into different rooms. The main engine won’t be in the same room as the air conditioning and heating systems. The main reason for this separation is safety, such as if there is an engine fire. A cruise ship engine room is incredibly noisy, exceeding 173 decibels.
A Guide to Cruise Ship Power Systems
In some accident situations, such as a fire or hull attack, multiple compartments on cruise ships support to contain the damage. On some ships where the engines are (exceptionally) appointed somewhere other than the underneath of the cruise ship, e.g., B. Queen Mary has four main diesel engines on the keel of these ships. The area in the ship which created the power to drive a skyscraper-sized vessel through the water, the engines room are commonly at least 3 to 4 decks high. The engine rooms are not too large as space is premium on cruise ships. Large equipment (propulsion motor, bow thrusters) requires electricity of high voltage.
Cruise Ship Fuel Consumption
Fresh water can be produced by reverse osmosis to supplement an evaporator. Space is needed not only for the massive engines, but for fuel tanks, generators, the engine workshop, and the control room. Regardless of the ship’s size and type of engine, engines are extremely loud. Engineers compensate for this fact by incorporating sound reduction features and technology to keep the room well insulated, so it is less noisy for guests. We outline what is contained in the cruise ship engine room, what it does, and how much noise and vibration is generated in this area.
How Are Engines Stored on a Cruise Ship?
Without a cruise ship engine, these vessels would be nothing more than a floating hotel. They would drift aimlessly at sea and would lack any form of propulsion. Looking at the sheer size of these vessels makes one wonder how large an engine needs to be to maneuver the ship successfully in water. Visiting the engine room of a cruise ship presents several benefits to passengers.
On newer cruise ships, engine rooms are found on the aft of the ship and on the lower decks. Storage requirements on board for LNG require very large tanks, so this type of fuel is most commonly being used on smaller ships that don’t travel as far, like ferries. But as the technology improves, it should start to be seen on larger cruise ships. How much is dependent on the size of the ship, the speed it goes, and the distance it travels. The amount of fuel an average cruise ship goes through in a voyage is generally around 300 tons a day. Because the pistons are fired by a consistent flow of electricity rather than burning fuel, they move at the most efficient speed.

It is because of not proper maintenance, some mechanical issues, and human errors; these all will be factors that cause the engine to fail. This correspondingly prevents warmness from fleeing to the bordering deck. To give you a conception of how loud the engine sounds, this has a range of over 173 decibels. This is so loud that this is in the pastureland, where hearing problems occur quickly.
Ballast Tanks
The cylindrical rotor sail has a height of 24 m (79 ft) and a diameter of 4 m (13 ft). This creates pressure/speed difference that moves it in the direction of the opposite (lower-pressure) side, creating a force at a right angle to the direction of the wind. Unlike traditional cloth sails, the rotor needs no furling (stowing), reefing (reducing sail's area) or line-tending. The rotor sail system is automated and shuts down when unfavorable changes in wind force or direction occur. "Rotor Sail Solution" is an innovative technology developed by the company Norsepower Ltd (Finland) in 5 years. It reduces fuel consumption and also COx emissions up to 900 tons per year (depending on wind conditions).
It provides an additional layer of protection and helps enhance the hull’s structural integrity. Given that the entire ship could sink if the hull was not strong, this inner layer serves a vital purpose in maintaining the ship’s safety and stability. Now that you have an understanding of the inner makeup of the hull, we can take a look at the exterior layers and structure. While it may look seamless from the outside of the ship, the hull of a cruise ship is made up of several segments that all serve a unique function. The cruise ship hull may be one of the most overlooked areas of the ship, but it serves a vital purpose.

The ECDIS allows for navigation of the ship without the need of traditional paper charts. Navigation can be done manually, automatically, or through the Navigation and Command System (NACOS). Speed affects cruise ship fuel consumption because to go faster, vessels must increase the electricity flow to motors.
The engines work the same as a traditional diesel engine, but rather than connecting to the propeller shaft – diesel-electric engines connect directly to large generators. For example, one person may be responsible for the freshwater generators and water pumps and another for the fuel oil systems. There are several reasons for keeping the cruise ship engine room away from passenger areas.
In this case, you may find that the gentle hum of the engine is actually helpful in drowning out some of the other sounds. 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. Cabins near the engine room are viable candidates for people who can sleep through a hurricane.
Cruise ships use low-grade diesel and tend not to burn it as clearly as road-running diesel-powered vehicles. All the ships in the world depend on the propellers which push them through the water, commonly known as the screws, which cut through the water and give the reverse and the forward motion. This type of engine provides enough electricity to move the ship’s propellers and power the cruise ship’s appliances, lights, air conditioning, etc.
This is where crews demonstrate how to safely use life jackets and outline a designated meeting point in the event of an emergency. Be sure you know where your life jacket is in your cabin in the event you should ever require one. To get an idea of how loud an engine is, it can have a range that exceeds 173 decibels. It is so loud that it is in the range where damage to hearing can quickly occur.
When the cruise industry began in the mid-1800s, vessels were propelled by steam engines. We’ll cover some of the most popular technologies used by cruise ships. The engines on a cruise ship can be up to 45 feet long, 27 feet high, and weigh up to 275 tons. Every piece of equipment can be monitored from the engine control room to ensure the cruise ship runs smoothly. Here’s everything you need to know about a cruise ship’s engine room.
Power is measured in horsepower traditionally - one horsepower equals 746 watts. The next photo shows the world's largest passenger ships' engine that powers each of the Royal Caribbean Oasis-class vessels. As you can probably imagine, cruise ships require a lot of fuel. Gas turbines, although they use a non-renewable energy source, are a greener option than diesel. They work the same way that diesel-electric propulsion systems do, and the heat that the turbines generate is often used for onboard electricity.
