The China-built ferryboat is equipped with two Norsepower-produced rotor sails, doubling its wind power potential. ABB supplied the vessel's power and electric propulsion systems, as well as the Octopus (smart energy management system). While mechanical propulsion is optimized for a single-speed, electric propulsion is based on rotating speed control resulting in energy efficiency at all speeds. ABB's propulsion also improves passenger comfort as the ship runs much more quietly and smoothly.
Beneath the Surface: Exploring the Cruise Ship Hull
It is powered by six marine diesel engines that put out 97,020 kilowatts (130,110 hp) which is used both to propel the ship and provide electricity to its passengers and entertainment facilities. The Oasis is also the first cruise ship to utilise Azipods instead of long screws with propellers on them. Azipods are propellers mounted to tubes which turn, making rudders unnecessary. The engine rooms of today that are the heart and soul of large cruise ships would be confusing and unrecognisable to the engineers and operators from the past. The big ships are still run on turbine power, but the similarities end there.
What Are the Cabins in this Location Like?
The engine rooms on a steam ship tended to be somewhat less safe than their diesel counterparts. A cruise ship hull will also contain ballast tanks, which help control the stability of the entire vessel. These massive tanks can be filled or emptied with seawater, which makes it possible to modify the ship’s center of gravity. Ballast tank adjustments are necessary to keep a cruise ship afloat and stable, so they are essential. It provides a physical structure for the ship to be built upon and the buoyancy required to keep the cruise ship and everything it is carrying afloat. The hull also helps reduce water resistance, which helps with everything from improving fuel efficiency to allowing the ship to travel through the water smoother and faster.
Marine diesel engines
The engine rooms are not too large as space is premium on cruise ships. But nowadays, modern cruise ships have less hull strength, agility, and speed than ocean liners. At the end of December 2018, there were globally 314 cruise ships operating with a combined capacity of 535,000 passengers. MS Viking Grace is also the world's first ship with the energy recycling system "Ocean Marine" (developed by Climeon AB / Stockholm-based company). The system converts the excess heat (generated by engines and exhausts) into clean (emission-free) electricity with an annual capacity of 700,000 kWh.

The engines aren’t quite at the back of the vessel but closer to midship. On September 7, 2015, about 1133 local time, a fire broke out in the engine room aboard cruise ship Carnival Liberty. At the time, the vessel was alongside the dock in the Port of Charlotte Amalie, St. Thomas, US Virgin Islands. The master ordered the passengers aboard the vessel to evacuate to the dock.

It houses the vessel's prime mover, usually some variations of a heat engine (steam engine, diesel engine, gas or steam turbine). On some ships, there may be more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered. To increase a vessel's safety and chances of surviving damage, the machinery necessary for the ship's operation may be segregated into various spaces. Nowadays, large modern cruise ships use two- or three-stroke, crosshead, low-speed, or medium-speed engines. The type of engine inaugurated on new cruise ships concerns studying engine measures. The output shafts are connected with electrical generators, which produce electrical power.

Cruise companies employ new technologies in order to reduce fuel consumption. Ship's hull, for example, can be applied by silicon coating in order to reduce friction as the ship goes through the water. Another experiment is LED lighting, using less energy and producing less heat (thus is reduced the demand for electricity and air conditioning).
How Does a Cruise Ship’s Engine Work?
While engine room visits may not be available on all cruise lines, several cruise companies recognize the curiosity and interest of their passengers and offer this unique opportunity. Royal Caribbean, Carnival Cruise Line, and Norwegian Cruise Line are among the popular cruise lines that allow engine room tours. Most modern-day cruise ships feature high-strength steel hulls. This durable material is required to withstand the immense pressure and stress of traveling through oceans and large seas. The next scheme shows the dual-engine powerplant (Wartsila) and propulsion (Azipod) of the cruise ferryTallink Megastar. This ship is the biggest "floating superstore" on the Baltic Sea, featuring a 2-deck retail shopping complex and the unique self-service option called "Q-shopping".
Without any power source, the cruise ship is just a floating hotel. In the older ship, diesel engines generate the power to run the cruise ship. The strength rendered by the engine is stored through a gearbox to the propeller shaft. Nowadays, modern ships use either their diesel-electric engines or gas turbines to power their engines and run them and also for the different systems of the ships.
24 hours of power are at least provided by battery rooms to the smaller emergency equipment list. All ships rely on propellers/screws to be pushed through the water, providing forward and reverse motion. Airplanes, for example, require tremendous propeller speeds to provide the forward motion, but ship propellers don't need to turn so fast and rely on torque power. Therefore, ships travel slowly and rarely top 30 knots (for more info follow our speed-link above). Cruise ship engine rooms are very large, spanning several decks. They need enough space not just for the engines, but also for the generators, the fuel tanks, the control room and the engine workshop.
The engines are located on the lower deck towards the aft in modern new cruise ships. These engines are not discovered downright in the row of the ship but in the middle of the ship. Engines of the independent cruise ship size have extremely loud sounds. 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.
Although you might envision the engine room as a massive open room running the ship’s length, the lower decks are divided into several water-tight compartments. One compartment may house the cruise ship water fresh water systems, another for the main engines, and another for the air conditioning. Passenger ships have come a long way from sails and steam engines.
Cruise ship engine technology has evolved from wind and sails to newer liquified natural gas technology. Thrusters, like main propellers, are reversible by hydraulic operation. You’re in for an off-the-grid explore-a-thon cruise that departs from Vancouver.

The hull’s outer plating composes the most visible layer of the hull. It protects the lower portions of the ship and provides the primary defense against external elements, like water pressure and floating objects. In most cases, this plating is made from hardened steel and coated with specialized paint that can withstand the corrosive effects of ongoing saltwater exposure.
The main reason people select an inside cabin on a lower deck is that they are less expensive. Most people book a cruise to have an experience – not to sleep. 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. They are distributed across the length of the cruise ship with ballast tanks. The only fuel tanks located in an engine room are service and settling tanks. Space is needed not only for the massive engines, but for fuel tanks, generators, the engine workshop, and the control room.
