Older cruise ships may still use a diesel reciprocating engine to generate enough power to move them. Power is supplied to the ship through a transmission going to a propeller shaft. As technology continues to advance, further improvements are being made in the efficiency and energy storage capabilities of hybrid electric systems. This, coupled with ongoing advancements in battery technology, will pave the way for even more efficient and environmentally friendly cruise ship operations in the future. LNG-powered engines demonstrate a significant step towards greener and more sustainable cruise ship operations. The use of LNG as a fuel source aligns with the cruise industry’s commitment to environmental stewardship, ensuring a cleaner and more sustainable future for both operators and passengers alike.
Jewel Class
The engines aren’t quite at the back of the vessel but closer to midship. Ships sail to ports around the world, bringing thousands of people in for the day. It makes sense then that a cruise ship requires powerful propulsion systems to keep them moving. Battery power is used during turnaround navigation in ports when the onboard diesel-electric generators are switched off. As of 2019, Corvus Energy delivered its innovative product line "Orca ESS" to 200+ vessel conversion/upgrade projects, totaling 200+ MWh.
Optimising ship lifecycle efficiency
The technology uses heat exchangers that evaporate a carrier fluid circulating in a closed system. This gas (at 2-bar pressure) drives a turbine, then a 100 kW generator produces electricity. After that, the gas is cooled (in a vacuum chamber) and liquefied. Then Heat exchangers cool the carrier fluid to temperatures around 20 C / 68 F. 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.
Diesel-Electric
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.
Cruise Ship Engine Room (Everything You Want to Know)
Technological advancement in the design of ships is making rapid advancements and cruise ships are no exception to this. Each passing year, new technologies are being conceptualized, designed, experimented and fitted on new ships. The cylindrical rotor sail has a height of 24 m (79 ft) and a diameter of 4 m (13 ft).
The number of engines range from five to six, and the power rating for each one is between 9-15 megawatts. Before the pandemic, about 10% of people that had never cruised said they "never" would. According to the survey, this number rose to 17% in June 2021, but fell to 14% by August. Though mass Covid-19 outbreaks early in the pandemic exposed health concerns surrounding cruising, a new survey indicates travelers may not abandon ship travel after all.
With the complex technology involved, it’s a huge milestone for the workers at the shipyard. It shows that the installation has succeeded, which is especially important for a new design. What everyone in the cruise industry should know about future-proof maritime solutions. In less than a minute, Maikel Arts, GM Technical Sales at Wärtsilä will reveal some interesting opportunities that hybrid systems can offer to the cruise industry.
Aeroderivative gas turbine powered cruise ships
A great example is a rock sinking vs. a beach ball floating on water. Using natural gas could reduce nitrogen oxide and carbon dioxide emissions significantly! With green-oriented companies, more green cruises have been released in the past few years. Just because it’s placed low in the ship doesn’t mean it doesn’t take a lot of space. For all the ship’s power, the engine rooms can take up several decks high and are generally divided into several compartments.

So How Do These Engines Make the Ship Move?
The deal was signed by Micky Arison (Carnival's Chairman) and Bjorn Rosengren (Wartsila's President and CEO). The plan included installing Wartsila's latest marine solutions, first tested on several Carnival Cruise Line vessels in pilot projects. The new systems and technologies included engine control and monitoring systems, safety and fuel efficiency equipment.
Overall, gas turbine engines provide an efficient and powerful option for cruise ships, particularly those focusing on high-speed travel. Their ability to quickly respond to power demands and lower emissions make them a valuable choice for enhancing the overall cruising experience. 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.
We’ve been improving them for 50 years, with 150 million operating hours worldwide. Learn more about our turbines and see which one’s right for your voyages. “The first main engine start on a ship largely tells a lot about the ship’s readiness. It is a sign that the various departments throughout the yard have achieved something significant. To achieve this milestone, all professional groups are needed, and for that, big thanks to everyone!
The LNG is stored at temperatures -160 Celsius (-256 Fahrenheit) and under pressure 4-6 bars. ABB Azipod propulsion systems have a major impact on the vessel's operating efficiency - reducing energy consumption and bad emissions by up to 20%. But really, the main reason to choose an inside cabin on the lower decks is that these are easily the cheapest room on a cruise ship. You’re going on a cruise for the experience, after all, not the nap time.
Smaller cruise lines — with ships that fit hundreds rather than thousands of guests — dominated U.S. Engine reliability is crucial to maintaining continuous operation without unexpected downtime or performance issues. Cruise ship operators rely on engines that have a proven track record of reliability and longevity.
Improper maintenance, mechanical issues, and human error can all be factors in causing engine failure. If the main engine should ever fail, power to electrical services should still run. It keeps out noise and reduces the heat generated by fully operating engines. The publication evaluated 17 cruise lines through a combination of expert evaluations (30%), traveler reviews (50%) and health ratings published by the U.S. Centers for Disease Control and Prevention's Vessel Sanitation Program (20%).
