Medium-sized ships will require 150 tons per day and as size decreases, fuel consumption does as well. A cruise ship engine room is incredibly noisy, exceeding 173 decibels. At this noise level, the noise in an engine room can cause immediate damage to your hearing without proper ear protection. Modern cruise ships are equipped with systems to “plug in” to the local power grid.
Are Passengers Safe if There Is Engine Failure?
Royal Caribbean’s Icon of the Seas has been under construction at Meyer Turku since the first piece of steel was cut on June 16, 2021. Construction milestones included the keel being laid for the first time in April 2022 and the ship floating out onto the water on December 2022. Royal Caribbean’s new LNG-powered Icon of the Seas has already reached some major milestones while under construction at the Meyer Turku shipyard in Finland. Now, the ship has reached another milestone, with the first of six engines getting started for the very first time.

Additionally, LNG is a cleaner-burning fuel compared to traditional marine fuels. Propellers, commonly called screws, are an integral component of any cruise ship, and are used to provide both forward and reverse momentum. These huge propellers rely on torque, or power rather than speed, to provide the motion required to propel a huge vessel often weighing over 200,000 tons.

Fuel efficiency and environmental impact are of paramount importance in engine selection. The adoption of LNG-powered engines and hybrid electric systems significantly reduces emissions, lowers fuel consumption, and minimizes environmental impact. LNG-powered engines utilize clean-burning liquefied natural gas to reduce emissions of sulfur oxides, nitrogen oxides, and particulate matter.

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. Steam powers two types of engine, reciprocating (with steam driving pistons connected to a crankshaft) and turbine (with steam driving blades attached radially to a spinning shaft).

Radars are devices that allow us to locate distant objects from a given location, regardless of visibility and weather conditions. The radar emits electromagnetic waves to an object, then receives back the reflected echoes from that object, and interprets them based on distances and angles. These interpretations enable us to determine where an object lies, and in some cases even what its contours look like. In the shipping industry, radars are used for monitoring traffic in ports and coastal regions, for collision protection, for collecting weather data, and for navigation. The bridge houses a number of important nautical devices and information systems for command and navigation of the ship. It is from there that the captain and his officers command and maneuver the ship, keep watch for other vessels or potential hazards, and navigate through the oceans.
Cruise Ship Engine Technology
®A damper winding is an extra winding in the rotor provided in order for it to start as an induction motor. Once it starts and the speed nears synchronous speed, DC excitation is supplied and magnetic locking takes place. It is solvable by the use of either an external prime mover or a damper winding. An external prime-mover rotates the rotor to a speed close to synchronous speed after which DC is available for magnetic locking. The lighter weight, even weight distribution and compactness of DE drives also contribute in the ease of control. The other lower voltage ship loads are also supplied from the HV busbar through step-down transformers thus eliminating the need for additional gensets and reducing costs.
Most larger ships have more than one engine room to house their machinery. The arrangement of the engine room can vary depending on the type, design, and size of the ship. For stability reasons, the engine machinery is typically placed as low as possible in the ship’s bowels and often takes up several decks in height.
Icon of the Seas Engines Started for the First Time
In submarines, the ability to run submerged at high speed and in relative quiet for long periods holds obvious advantages. A few naval cruisers have also employed nuclear power; as of 2006, the only ones remaining in service are the Russian Kirov class. An example of a non-military ship with nuclear marine propulsion is the Arktika-class icebreaker with 75,000 shaft horsepower (55,930 kW). In an ice-breaker, an advantage is fuel security and safety in demanding arctic conditions. The commercial experiment of the NS Savannah ended before the dramatic fuel price increases of the 1970s. The Savannah also suffered from an inefficient design, being partly for passengers and partly for cargo.
The Magic Carpet, for instance, was the world's first cantilevered floating platform that reaches 13 stories above sea level. By day, it is used as a gangway to help passengers board tender boats, and at night, it is transformed into a dining venue and trendy bar. If you’re looking for an outstanding cruise ship cabin that’s as quiet as possible, it’s important to know where the engine room is so that you can stay well away from it.
Even if you choose to stay in one of the most expensive suites on the ship, this doesn’t guarantee that you’ll be able to rest undisturbed. There are plenty of other things that could keep you awake at night on a cruise ship. The heat from the engines is removed by a series of heat exchangers. This is found on the exhaust path proceeding the turbocharger on the way to the scrubber.
Generally, engine failure only generates a brief interruption before it’s fixed. Cruise lines will never jeopardize the safety of guests nor put them at risk if the cruise ship is unsuitable for sailing. If it does happen, the captain consults the chief engineer to diagnose the cause of the malfunction. In newer cruise ships, engines are found on the lower decks toward the aft. They are not completely to the back of the boat but are found in the mid-aft.
Booking this room may mean you will experience vibrations and noise from the engine. You may hear the crew as they go back and forth to the engine room throughout the day and night. If you are in the engine room while the engine is running, it will still be very loud regardless of what noise-reducing technology is used. To put it in perspective, those who enter the room are required to wear hearing protection.
Speed affects cruise ship fuel consumption because to go faster, vessels must increase the electricity flow to motors. Thus more engines are employed, and it, in turn, increases fuel consumption. For example, Queen Mary 2 consumes 237 tons MGO and 261 tons HFO a day when at full speed. After a certain point, the rate of return decreases from adding engines, because if a ship can manage 17 knots by two engines, it doesn't mean that four engines are going to produce 34 knots.
A shaft generator converts the circular motion of the propeller shaft into electricity. Cruise ship engine technology has evolved from wind and sails to newer liquified natural gas technology. These massive engines can propel cruise ships at an average speed of knots. Crew members can monitor the ship’s systems from the engine control room. From the operation control center, crew members monitor the ship’s systems and act as a central area for maintaining the technical equipment on the cruise ship.
