The engines are not exclusively LNG, but "dual fuel" (capable of burring both liquid marine fuel and natural gas). This design is for saving onboard space (reducing fuel storage space required). The basic detail about the cruise ship engine room is its location. For stability, the ship's heaviest weights are at its lowest possible deck, and usually, engines are mounted above the keel. An area creating enough power for driving such an enormous vessel through water needs to be really big - very often engine rooms occupy at least three decks. Rather than long halls stretching the length of hulls, machinery is almost always divided into smaller compartments - one for the main engines, another for the heating/air-conditioning system.

In this article, we will explore the importance of engines for cruise ships and the different types of engines used in these vessels. We will also delve into the factors considered when selecting an engine for a cruise ship and discuss the latest technological developments in cruise ship engines. Passenger ships have come a long way from sails and steam engines.

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. Crystal cruise ships are powered by two "Azipod D" units allowing navigation in polar destinations. Each of the Star Cruises "Global-Class" vessels have three "Azipod XO" thrusters. All ships have installed ABB's "Intelligent Maneuvering Interface" and the "OCTOPUS" software optimizing fuel consumption and energy management. All these ships were constructed by the German shipbuilder MV Werften.
LM fuel-condition monitoring
This must start and come on load within 45 seconds of a power failure and supply power to the emergency switchboard. The switchboard provides power to selected critical equipment during blackout. The alternator supplied 3-phase power usually of either 6.6 kV or 11 kV to the main HV busbar from where it is either used directly or stepped-down to lower voltages. Each DG room has its independent air, fuel, lubrication and cooling water supply systems.
Cruise ship engines, propulsion solutions and more
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. Royal Caribbean vessels of Oasis, Freedom, and Voyager classes have pod-propulsion as many other big ships, which is opposed to the fixed traditional screws which push in one direction only. Emergency generators are instead used only for essential navigation systems - crucial communication equipment, critical pumps in the engine room, emergency lighting.

You may find that the vibrations cause the coathangers in your wardrobe to rattle, which could disturb your sleep. If you were to place a cruise ship motor right out in the open and crank it up, you would get an ungodly level of noise. However, since we can’t really do that, we can only go off of how many decibels it puts out when under operation, in place, on a cruise ship.
Importance of Engines for Cruise Ships
While the cruise ship constantly pushes the water out of its way when moving forward, the water being pushed will try to come back to its place. This displaced water pushes back with a force on the vessel which lets the cruise ship stay afloat. This electricity also provides direct power for the ship’s lights, appliances, and much more. As shown in the table, depending on the vessel type, the engine will provide power to different aspects of the ship.

Higher propulsion redundancy
Their continuous development and improvement ensure that cruise ships can provide a memorable experience for passengers while minimizing their impact on the environment. The choice of engines for cruise ships is a critical decision that takes into consideration factors such as power requirements, fuel efficiency, environmental impact, reliability, and safety. Over the years, there have been significant advancements in cruise ship engine technology, leading to the emergence of more sustainable and innovative options.
What are Cabins Near the Engine Room Like?
The engines are turned on for the very first time on Royal Caribbean's first-ever Icon-class mega-ship at the shipyard. Generators power all the vital functions to run a ship, like emergency lights, communications, and navigation systems. If the generator fails, then there are also backup batteries that can be used for short periods of time.
Since they are so large, they are placed in a separate compartment found in the cruise ship’s machinery space. Modern passenger ships contain two DG rooms, which are forward and aft. However, a direct drive system is used as opposed to a turbine. Output shafts are used to generate electrical power and are connected to the generators. Gas turbine engines create heat that transforms mechanical energy into electricity.
These engines operate on the principle of internal combustion, where fuel is injected into compressed air, leading to combustion and the generation of power. The ambition in the cruise industry is to go above and beyond – to exceed expectations. This is as true for the guest experience as it is for the industry’s drive to reduce emissions and decarbonise. When the goal is net zero operations, cruise ships need a range of sustainable engines, propulsion solutions, maritime technology, and services. Not all cruise ports have facilities to enable shore-to-ship energy.
Cruise ship engine power is supplied through the transmission to the propeller shafts. Modern ships use either diesel-electric engines or gas turbines as a source of power for propulsion, and for ship's systems. Some of the larger ships depend on two power sources - one for electrical power and one for propulsion. Engine manufacturers work closely with cruise ship operators to determine the power requirements and customize engine designs accordingly. The goal is to ensure that the engines can provide the necessary power for propulsion and onboard systems, while optimizing fuel efficiency and maintaining operational reliability.
Today cruising is one of the most popular vacations, but there are significant environmental downsides. Mega-ships burn the dirtiest fuel in the world, even if they are sitting in port. Asthma, cancer, respiratory illness, heart disease, are the results of burned in ports nasty bunker fuel. "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). In comparison to pipeline gas, LNG is superior in quality - purer, with more methane and other energy content.
This is a direct current (DC) supply obtained from the main busbar after transformation and rectification. There are also two harmonic filters provided, at the port and starboard ends of the main HV busbar. These filter out unwanted harmonics generated by frequency converters and other HV components. 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. Since you’ll be in the middle of the ship and on a lower deck, your cabin will be dark and windowless.
At the following tag-link can be found listed all CruiseMapper's news related to propulsion-power accidents. The AIDAprima ship's first successful test run for LNG supply was in Hamburg Germany on May 7, 2016. While berthed, the ship was successfully provided with LNG at all the itinerary's ports of call (Hamburg, Rotterdam, Le Havre, Southampton, Zeebrugge). Fincantieri used Promas Lite propulsion for all Viking Ocean liners.
