Battery rooms provide at least 24 hours of power to an even smaller list of emergency equipment. However, the essential systems they supply are so limited, they cannot power many hotel services and are certainly not enough to move the ship. So what happens when things go wrong and the ship is dead in the water? All ships have an emergency generator to maintain vital electrical power.
A Guide to Cruise Ship Power Systems
The propulsion motors are themselves much more compact and lighter than conventional engines and being two in number. In addition to this, there is also an additional auxiliary diesel generator for the restoration of power during blackout situations. This generator can be started to power the 440V busbar independent of the main supply, in order to prepare the plant for restart. As we can see, the diesel generators (shown 4 in number) supply 3-phase high-voltage power to the HV busbar rated at either 6.6kV or 11kV.
All-electric passenger ships
On board, a computer converts these signals into the exact position of the ship at a given time. On large ships, the position indicator is constantly recorded in a so-called electronic nautical chart. Grandpaw’s almost mystical tool shed was strictly off limits, but we were just dying to have a peek, weren’t we? Now that we are all grown up, Grandpaw’s gadgets are old news, but there is still a place or two on a cruise ship that remains like a pie in the sky for all of us obsessed by ships.
Conventional Diesel
The engines must be able to operate consistently and safely throughout the voyage to provide a smooth and worry-free experience for passengers and crew. By prioritizing fuel efficiency in engine selection, cruise ship operators can achieve significant cost savings and reduce the environmental footprint of their operations. The power requirements of a cruise ship are a primary consideration when selecting an engine. Various factors influence these power requirements, including the ship’s size, weight, intended speed, and onboard facilities.
Then steam is used to heat fuel and QM2 hotel accommodations, laundry, galleys. This reduces the energy amount that has to be produced by ship's engines. The Promas Lite system (mentioned above) generates cruise ship fuel savings in the range of 5-15% depending on the operation type and the actual performance of the ship's existing propeller. Added to the dual-fuel engines, the new technology makes Viking Grace one of the world's most environmentally-friendly passenger ships, operating with very low levels of emissions and noise. Norsepower's wind propulsion system was also installed on VIKING LINE's newest vessel (still unnamed) scheduled for delivery in 2020. The China-built ferryboat is equipped with two Norsepower-produced rotor sails, doubling its wind power potential.
Are Passengers Safe if There Is Engine Failure?
The rotor sail system is automated and shuts down when unfavorable changes in wind force or direction occur. In April 2018, the Norwegian cruise and ferry company Hurtigruten announced a USD 150 million fleet renovation project. Almost all vessels will be upgraded with new hybrid powerplants that combine LNG-engines and batteries. The LNG cruise ship concept was first introduced by Wartsila (Finnish manufacturing company) and is based on drive shaft propulsion instead of azipods.
Diesel-Electric Cruise Ship Engines
These rotor sails are very sensitive to the wind and can shut down when conditions are unfavorable. If you have ever taken a cruise or seen one come into port, you may have wondered what it makes it move. This guide should answer your questions and make it all clearer. If anything, the vibrations caused by the engines are more likely to cause annoyance over the sound of the engine.

This is generally not healthy to drink, so this water is mineralized and chlorinated for taste and safety. Chris Millman, Vice President Marine Technology for Carnival reveals how Carnival gets the critical data and insight that will help to decarbonise its existing vessels and newbuilds. Wärtsilä has a five-step approach to ensure you remain competitive, compliant and profitable. Wärtsilä offers a comprehensive portfolio to support cruise operators on their decarbonisation journey – for retrofit projects and for future-proof new builds. An option to upgrade doesn’t necessarily mean that more money will be required.
Both catamarans are 100% emission-free being powered by high-capacity batteries. Each ship is fitted with two battery packs (combined capacity 316 kWh / 563 HP output). The electricity is provided by 2 fully-independent power systems and split evenly between the 2 hulls. Gas fuel eliminates all the bad emissions - soot and sulfur oxides. In April 2016 MSC Cruises announced its contract with STX France for up to four LNG-powered ships with GT over 200,000 tons each. The new MSC ships have 5400 passengers capacity at double occupancy each.
You can purchase a cabin that’s near the engine room for an outstanding price, with the option to upgrade. Since you’ll be in the middle of the ship and on a lower deck, your cabin will be dark and windowless. For obvious reasons, rooms situated towards the centre of the ship arent’ afforded the luxury of windows, so if claustrophobia is an issue for you, stay away. Icon of the Seas will be delivered at the end of 2023 following the necessary sea trials. The first guest sailing will be a seven-night Caribbean itinerary with visits to St. Kitts, St. Thomas in the US Virgin Islands, and the Royal Caribbean private island of Perfect Day at CocoCay.
This proactive approach to maintenance ensures that the engines remain in optimal operating condition, reducing the risk of unexpected breakdowns or accidents. These certifications ensure that the engines meet essential safety requirements and undergo regular inspections and audits. Premium cruises generally have a refined style in comparison to mainstream cruise lines.
Overall, COGAS systems represent an advanced and environmentally friendly solution for powering and propelling larger cruise ships. Their high efficiency, flexible power output, and lower emissions make them a notable choice for cruise lines seeking to optimize energy usage and reduce their environmental footprint. The power generated by the main engines/powerplant produces electricity that is used from the propulsion motors, as well as all auxiliary systems and hotel functions. This innovative maritime technology allows the engines to be started and stopped depending on the onboard electricity demand, which additionally improves fuel efficiency.
This guide to cruise ship power systems will explain everything it takes to move cruise ships from port to port worldwide. Cruise ship power systems can vary from ship to ship, but every ship has an engine that uses fuel, usually diesel or gas, sometimes with supplemental electricity. Usually, ships are powered by four or five generator sets (medium-speed, 500 revolutions per minute), fueled by diesel and creating 8-10 MW energy each. The power density of marine diesel medium-speed engine is 80 kilowatts per cubic meter. Ships that use diesel engines are required to carry exhaust-treatment systems and catalytic-reduction equipment to reduce the environmental impact.
This has led to the development of technologies like LNG (liquefied natural gas) fuelled engines and hybrid electric systems, which further enhance the efficiency and sustainability of these engines. Without efficient and reliable engines, cruise ships would be unable to function effectively. The engines not only determine the speed and maneuverability of the ship but also ensure the seamless operation of all onboard systems.
However, guests don’t have to be concerned if their cabins are in this area. The noise level will not damage your hearing because the surrounding cabins are well insulated. However, you may still be able to hear the noise and experience vibrations through the walls and floors.
