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. The engine room is usually located near the bottom, at the rear or aft end of the vessel, and comprises few compartments. This design maximizes the cargo carrying capacity of the vessel and situates the prime mover close to the propeller, minimizing equipment cost and problems posed from long shaft lines. On some ships, the engine room may be situated mid-ship, such as on vessels built from 1900 to the 1960s, or forward and even high, such as on diesel-electric vessels. The No. 1 priority of all cruise lines is to keep all their guests completely safe.

You see not only engine controls, but firefighting controls, environmental controls, temperature, etc. I can understand why they don't offer tours of the engine room - aside from concerns about mobility, you'd probably need to wear ear plugs or headphones - they're pretty much standard equipment in an engine room today. 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. If the main engine should ever fail, power to electrical services should still run. 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).

Art galleries onboard cruise ships are another option for those seeking cultural enrichment. Many ships feature curated collections of paintings, sculptures, and other forms of art, allowing passengers to indulge in an immersive art experience while onboard. Visiting the engine room of a cruise ship presents several benefits to passengers. Firstly, it offers a rare opportunity to witness firsthand the sophisticated technology and engineering marvels that power the vessel. Understanding the inner workings of a ship can be both educational and awe-inspiring, allowing passengers to gain a deeper appreciation for the complexity involved in operating a cruise ship.

The rotor sail system is automated and shuts down when unfavorable changes in wind force or direction occur. 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.

The experience most often includes the executive chef leading a small group of guests to a table in the galley itself, while on other ships there is a dedicated intimate dining space. Bring your best cruise attire -- it's always a formal affair with the Captain. We only have two sea days, and I didn't want to hog the last sea day alone on a tour.

Ships' batteries are charged using hydropower (water-generated electricity), which as of 2019 accounts for ~7% of the USA's total electricity production. 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.

Currently, NCL Norwegian Epic has two rudders with conventional non-Azipod screws. But how does she manage to maneuver if they can push in one direction only? One option is to make them bigger and more effective when maneuvering, another is to add additional mini-pods or install full-sized pods. ABB also supplies the power generation, distribution systems, bow thrusters, and of course, the 2 x 20,500 kW propulsion Azipod XO units (at the photo at right), transformers and drives.

The main engines and even the generators themselves require electricity to keep going. Electrically driven pumps take in cold seawater from the ocean to help cool the engines; electrical pumps take fuel from the fuel tanks and supply it to the engine. Electrical power is critical to many operating functions, and without it, the ship comes to a halt. LNG-powered ships have engines that are modified to burn natural gas that has been turned into a liquid and kept at a temperature 260 degrees below zero in specially insulated fuel tanks.

Numerous machines and pieces of equipment are essential to the entire ship’s safe operation down in the hull, so it needs to be protected. While these tanks and treatment systems are incredibly sophisticated and far more sanitary than you may assume, they still sit out of view of passengers. This explains why they are almost always located in the ship’s hull. Like just about any type of large vessel, a cruise ship hull will feature numerous different compartments and spaces. As you will learn, each plays an essential role in allowing the ship to function safely.

The four newbuilds became the industry's first LNG (Liquefied Natural Gas) powered vessels using LNG in their hybrid engines. The gas is stored in the ship and used to generate all needed power at sea. 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). Both self-unloading dry bulk vessels were China-built (by Chengxi Shipyard Co Ltd / subsidiary of CSSC) and scheduled for deliveries in 2021. It is here that pistons hammer and crankshafts turn to propel the ship forward.

Even ships with two engine rooms can suffer power failure if the electrical cables are not truly redundant. For instance, if two main engines in different engine rooms produce power that goes into a single cable that brings power to the propulsion motors, a problem to that electrical cable would cut off all propulsion power. Of course, the production of electricity is vital to all aspects of a ship's operation. Large equipment (such as the bow thrusters, or, in the case of diesel electric ships, the actual propulsion motor) requires high-voltage electricity.

Like any hospitality operation, the "front of house" only scratches the surface. It's the "back of house" that forms the humming heart of the ship. Separate passageways, sections and whole decks can be set aside for crew operations, with only a few passengers allowed behind the scenes. After you score your next cruise deal, consider one of these five ways to see another side of cruising.

However, if it is no longer possible to use the seabed as a reference, the device uses particles suspended in the water, such as plankton and minerals, to measure travel through the water. As mentioned, the engine does make vibrations while it operates. They can be felt in the surrounding areas, including cabins that are adjacent to them.
