Emergency generators are instead used only for essential navigation systems - crucial communication equipment, critical pumps in the engine room, emergency lighting. Should they also fail, vessels are required to have a battery backup. 24 hours of power are at least provided by battery rooms to the smaller emergency equipment list. Big ships require much power, so they might have more than one emergency generator. Despite that, they don't have the capacity of main generators and engines, don't produce electricity enough to move the ship, and can't supply all the power needed in ports, because of constraints in space. Wartsila's fuel engine package was specifically designed to reduce fuel consumption.

What Engines Are Used in Larger Ships?
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. Since there is so much space available in the hull of a cruise ship, it is a good location for various storage compartments and refrigeration rooms. Depending on the ship’s needs, these storage areas can be used to store everything from food and beverages to medical supplies and bedding. Even though it may seem less glamorous than other aspects of your vacation, it is worth considering the ship itself.

Electrical Department
Instead of the more traditional engine-shaft-propeller arrangement, in this case the engines are connected to generators to create electricity. The generators power electric motors, and the electric motors move the propellers. As you'd expect, an area that creates enough power to drive a skyscraper-sized vessel through the water is large -- and engine rooms are often at least three decks high. But because space is at a premium on cruise ships, engine rooms might not be the vast, cavernous space you envision. Rather than a long, continuous hall stretching the length of the hull, machinery is divided into smaller watertight compartments. One area might contain the main engines; another compartment might house the air conditioning system.

Ever wondered what goes on inside a cruise ship and what makes it all tick? From food prep at specialty restaurants to what room stewards do for their guests, there's only so much information the average passenger can glean about life onboard ships. While I have to admit to some bias here (my son is studying to become a ship's engineering officer at the US Merchant Marine Academy), I really thought the engine control room was one of the highlights of the tour.

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. Each cruise line has its own policies and procedures regarding these visits, so it’s advisable to check with the specific cruise line before booking your trip to ensure engine room tours are available.
Wow, we certainly learned a lot about cruise ships!
This technology allows sulfur emissions to be reduced by 99%, and NOx emissions - by 75%. 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. Most of the world's largest cruise ports have such dockside electrical hookups, reducing bad emissions by up to 95%. All the ship's electrical equipment is certified "explosion-proof".
Due to high specifications and standards, it is rare for a cruise ship to experience engine failure. The International Maritime Organization has a “Safe Return to Port” initiative. It keeps out noise and reduces the heat generated by fully operating engines. The high voltage switchboards require special training and procedures, with regards to electrical safety, which cruise ship electricians are equipped and certified with. It is one department that has a large scope of work as electrical installations and equipment are everywhere on the ship, many of them requiring everyday checks and maintenance, both regular and breakdown.
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). The Promas Lite propulsion future clients, besides passenger ships, are marine vessels like fishing and freighter ships. 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).
Main Plant & Environmental Engineering
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. Today, more and more ports (and ships) are being fitted with systems that allow a ship to literally "plug in" to a local shoreside electric grid when docked. The ship's engines can be turned off, which helps reduce emission and pollution. Possibly the most basic detail to understand about the engine room is its location.
However, thanks to insulation and other sound reduction technology, it’s not nearly that loud in practice. Regardless of the size of the cruise ship, the engine in question is very, very loud. Fortunately, engineers can compensate for this by utilising sound reduction technology and designing the engine room of a cruise ship to be well-insulated. Perhaps you’re fascinated with the engines that power a cruise ship, or perhaps you want to know which cabins to stay well away from, due to the noise and vibrations of the engine. Cruise Hive was established back in 2008 and among the earliest blogs in the industry.
On a ship, the engine room (ER)[1] is the compartment where the machinery for marine propulsion is located. The engine room is generally the largest physical compartment of the machinery space. 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.
However, on certain cruise lines, visiting the engine room may attract an extra fee. Typically, if additional charges apply, they are minimal compared to the overall cost of the cruise. This durable material is required to withstand the immense pressure and stress of traveling through oceans and large seas. A cruise ship hull will also contain ballast tanks, which help control the stability of the entire vessel.
