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. A cruise ship engine room is incredibly noisy, exceeding 173 decibels. At this noise level, the noise in an engine room can cause immediate damage to your hearing without proper ear protection. But most of the energy produced by the ship’s engines goes towards powering the propellers, and running the engines while docked created massive energy waste.
How much fuel do cruise ships use?
In comparison to pipeline gas, LNG is superior in quality - purer, with more methane and other energy content. Its chemical structure also has a stable composition that doesn't generate unburned residues, soot or any particulates. In addition, because the fuel is so clean, on LNG-powered ships maintenance intervals are doubled (over 25,000 hours / ~10140 days), as opposed to the standard MDO-powered 12,500 hours (520 days). Gas fuel eliminates all the bad emissions - soot and sulfur oxides. In April 2016 MSC Cruises announced its contract with STX France for up to four LNG-powered ships with GT over 200,000 tons each. The new MSC ships have 5400 passengers capacity at double occupancy each.

Flying to Fort Lauderdale cruise port
You may hear the crew as they go back and forth to the engine room throughout the day and night. 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.
Marine steam engines
Here’s everything you need to know about a cruise ship’s engine room. Given that the bridge is one of the most crucial components of any cruise ship, it is helpful to familiarize yourself with the various areas found in this area of the ship. It’s worth a tour of the essential location to discover what goes on behind the scenes.
LNG Powered Ships
The Safety of Life at Sea Act was actually passed in the United States back in 1914 in response to the Titanic disaster. In 1948 it was adopted by the International Maritime Organisation and is generally considered the current standard by which ships are measured for safety. The Act has been modified a number of times over the years with the most recent change going into effect in 2010. It is these guidelines that are primarily responsible for the change from steam to gas or electric turbine power. The engine rooms on a steam ship tended to be somewhat less safe than their diesel counterparts. This durable material is required to withstand the immense pressure and stress of traveling through oceans and large seas.
The output shafts, to produce electrical power, are connected to generators. Some cruise ships used smaller generators to power the hotel and amusement functions. The smaller generators allow cruise ships to shut off the main engines in port, reducing pollution. The special engines of LNG-powered cruise ships use natural gas cooled to approximately -260°F. Once cooled, the liquid form of natural gas is about 600 times denser than natural gas, making it easier to transport.
Using Wind Propulsion Like a Sailing Ship
A shaft generator converts the circular motion of the propeller shaft into electricity. 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.
If you would like to know more about the interior of a cruise ship bridge, we can help! Jenna DeLaurentis enjoys exploring new ports of call around the world on a cruise ship, learning about new cultures, discovering beautiful landscapes, and trying diverse cuisine. She loves to get active while at port, whether cycling through mountains in the Caribbean or scuba diving under the sea.
That’s why we interviewed Chief Engineer Rhea Wilson and her team to get the inside scoop on everything related to ship mechanics and operations. They break down how cruise engines work, where the water you’re drinking comes from, how cruise ships detect icebergs, how they avoid icebergs, and — yeah, a lot of other iceberg-related questions. If you knew nothing about ship mechanics before, that’s about to change.
Fort Lauderdale is a vibrant vacation destination on its own, but it's also one of the easiest home ports for embarking on a cruise. Port Everglades is so close to Fort Lauderdale-Hollywood International Airport; it's a breeze to make your way from your flight to ship. Check out upcoming cruise itineraries and see if it's the right embarkation port for you. Some engine room tours may also incorporate interactive elements, providing visitors with hands-on opportunities to engage with the equipment and gain a deeper understanding of how it all works. These interactive elements can be both educational and entertaining, offering a unique perspective on the inner workings of a cruise ship. As you venture into the engine room, you’ll encounter a myriad of equipment that powers the ship.
They ensure the large vessel maintains its speed, direction, and course. The helmsmen or helmsman steers the ship according to the captain’s directions. They also maintain regular contact with navigation officers, ensuring the cruise ship stays on course. The captain will spend most of their time on the bridge in the command center.
Diesel engines have greater fuel efficiency at slower speeds, and the high gas price compared to diesel makes them more costly to operate. Cruise ships may have four to six medium-speed (500 rpm) engines producing 8-10MW each. Again, if you are lucky enough to participate in a bridge tour, it will take place while the ship is in the harbor. You may also be required to stick to strict behavioral guidelines and even follow a specific dress code.
The engine room still looks the same as it did before the conversion. With the conversion, QE2 sailed the seas for another twenty-two years. Don’t expect any cruise offers to travel on her this year, though. In 2010 she’ll be converted to a luxury hotel and remain stationary where she is currently docked in Dubai. A high end shopping and entertainment complex will be built around her.
For twenty-four hours each day, the bridge is occupied by two Deck Officers and two Able Seamen, traditionally in four-hour shifts. 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. Grandpaw’s almost mystical tool shed was strictly off limits, but we were just dying to have a peek, weren’t we? 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.
