The LNG is stored at temperatures -160 Celsius (-256 Fahrenheit) and under pressure 4-6 bars. AIDAprima (2016) is one of the world's most technologically advanced cruise vessels. The LNG cruise ship concept was first introduced by Wartsila (Finnish manufacturing company) and is based on drive shaft propulsion instead of azipods. The LNG tanks' location is in the upper deck area (right below the funnels).
AIDA's LNG-powered cruise ships
Open 24 hours a day, seven days a week, you can order your favorite egg dishes, pancakes, waffles, breakfast wraps and more. At dinnertime, they serve pork chops, country-fried steak, St. Louis ribs and fried chicken, among other hearty plates. If Seafarers' House doesn't have what you need before embarkation, there's a CVS at 1700 Federal Highway, about a 10-minute drive from port and close to the hotels we mentioned above. There's also a Publix grocery store (1940 Cordova Road) and Total Wine (1906 Cordova Road) in that area in the Harbor Shops plaza. While the 4,200-square-foot facility is designed to provide services to crewmembers, cruisers are also welcome.
Marine steam engines
Most often, especially in newer cruise ships, the engines are located on the lower decks and towards the aft of the ship. They’re not all the way in the back, but they are in the mid-aft area. 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.

However, you may still be able to hear the noise and experience vibrations through the walls and floors. 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.
These ships contain massive amounts of steel and other components, which contribute to its overall weight. It requires anywhere between five-to-six engines for it to function. While cruise ships can move upwards of 34.5 miles per hour (30 knots), most will only travel at 23 miles per hour (20 knots). There are various reasons for speed variations which are outlined in detail in this article. The largest cruise ship, Wonder of the Seas, utilizes six marine-diesel sets, with each composed of three 16-cylinder Wartsila engines.

Since the engine is located in the centre/aft of the ship and on the lower decks, these rooms are not priority rooms within the context of ship design. Cruise ship engines also create vibrations under operation and those vibrations are going to be felt within the immediate area, including adjacent cabins. You may find that the vibrations cause the coathangers in your wardrobe to rattle, which could disturb your sleep. All this machinery is overseen by the Engine Control Room, which contains lights, screens, alarms, and switches where every piece of equipment can be monitored to ensure the cruise ship runs smoothly.

Every piece of equipment can be monitored from the engine control room to ensure the cruise ship runs smoothly. There are several reasons for keeping the cruise ship engine room away from passenger areas. Some will allow passengers to meet the captain and other high-ranking officers during a guided tour. During some of these tours, it is possible to get a limited look at the bridge and explain how the equipment on the bridge actually works. While some will allow a small number of passengers to have a limited tour of the bridge, mainly while the ship is in port, the area is almost always only accessible to authorized personnel. The engine officer is the direct link between the engine room and the ship’s bridge.

These vessels, both as design (hull and superstructure) and implemented technologies, are highly energy-efficient. The advanced exhaust cleaning system uses a catalytic and scrubber converter. This technology allows sulfur emissions to be reduced by 99%, and NOx emissions - by 75%.

The engine's effectiveness depends not only on the design but also the ship's shape, weight, and size. 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. These ships incorporate a complete ABB propulsion - Azipods, electric power plant, computer automation, and software.
Promas propulsion integrates propeller, hubcap, rudder bulb and the rudder into a single unit which can increase propulsion's efficiency by 3-8% (1-screw vessels) and by 2-6% (2-screw vessels). It also improves maneuverability, reduces fuel consumption and bad emissions. The new modular technology allows efficient and cost-effective custom-made systems to be built up from various existing and standard parts - mooring winches, anchor cable lifters, warping heads. Azipod marine ship propulsion is a combination of both steering and propulsion systems. This system's steering is done by a rudder (in the propeller's aft). Emergency generators are instead used only for essential navigation systems - crucial communication equipment, critical pumps in the engine room, emergency lighting.
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. It is here that pistons hammer and crankshafts turn to propel the ship forward. It is the loud and oily place where the Chief Engineer and his team work around the clock to ensure that everything is running smoothly. It is the engine room of the ship that allows for the luxuries of air-conditioning, electricity, and plumbing on board cruise ships. Those who support the cruise industry point out that cruising has never been more popular. A solution is to have docked vessels plug into the port's shore power grid.
If you're flying into MIA, however, which is about an hour's drive to Port Everglades, you should price out the cruise line's transfer option and see what's a better deal. As your packing for your trip, don't forget to bring any credit cards that confer lounge benefits. For example, while FLL doesn't have a Priority Pass lounge, it does offer a credit at Kafe Kalik in Terminal 4. Your Chase Sapphire Reserve® and Hilton Honors American Express Aspire Card come with a Priority Pass membership (enrollment required) — as do many other credit cards. Off-site parking will be a bit cheaper, with prices around $6-10 dollars per day, and include a shuttle service to and from the parking lot to the port. Generally, the closer a parking lot is to the terminal, the more expensive the daily parking fee will be.
Diesel engines are the most traditional type of cruise ship engine. Older cruise ships may still use a diesel reciprocating engine to generate enough power to move them. Power is supplied to the ship through a transmission going to a propeller shaft. Cruise ships also have an echo sounder, a device used for the electro-acoustic measurement of water depths (sounding). The depth is determined by measuring the time between the emission of a sound impulse (water sound) and the arrival of the sound waves reflected from the bottom of the sea.
Battery power is used during turnaround navigation in ports when the onboard diesel-electric generators are switched off. As of 2019, Corvus Energy delivered its innovative product line "Orca ESS" to 200+ vessel conversion/upgrade projects, totaling 200+ MWh. For most vessels, the average consumption is miles on a fuel gallon. Ships' gas mileage varies depending on the type and size of ship, the number of passengers on board, and other factors. Some of the lines (including Celebrity and Cunard) have suffered vessel breakdowns due to pod-bearing failures.
