These systems provide the necessary propulsion and electricity generation, supporting the operation of various onboard facilities and amenities. While gas turbine engines offer several advantages, they also have some considerations to take into account, such as higher fuel consumption at lower speeds and the need for regular maintenance. However, ongoing advancements in gas turbine technology continue to improve their efficiency, reliability, and environmental performance.
All-electric passenger ships
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%. For most vessels, the average consumption is miles on a fuel gallon.
What a Cruise Ship Engine Room Looks Like
Only a few ships use wind power, but it is a viable option for future ships. Wind power is the traditional method of sailing, and it makes sense to return to it in an effort to be more environmentally conscious. This type of propulsion was pioneered by ABB in the late 1980s and has gone on to become a popular choice amongst passenger ship owners. It has become popular as AZIPOD, a name which has become synonymous with this type of propulsion, somewhat like XEROX for photocopiers.
Combined Gas and Steam Turbine Engines (COGAS):
This results in reduced emissions and improved fuel efficiency. 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. Cruise ships require significant power to propel the vessel and operate numerous systems and amenities. COGAS systems are commonly used in larger cruise ships due to their enhanced efficiency and power output capabilities.
For example, cruise ships avoid fines by taking specific lines. They must often save fuel and hiring a knowledgeable captain who can make these decisions and keep passengers aboard safe is essential. In general, a large cruise ship can consume up to 250 tons of fuel a day, which is close to 80,000 gallons a day. For medium size cruise ships, consumption can still range up to 150 tons of fuel a day.

Promas propulsion integrates propeller, hubcap, rudder bulb and the rudder into a single unit which can increase propulsion's efficiency by 3-8% (1-screw vessels) and by 2-6% (2-screw vessels). It also improves maneuverability, reduces fuel consumption and bad emissions. The new modular technology allows efficient and cost-effective custom-made systems to be built up from various existing and standard parts - mooring winches, anchor cable lifters, warping heads. Cunard QE2, for example, consumes daily 380 tons of fuel when traveling at 29 knots speed and carries fuel enough to sail for 12 days. Usually, ships fill up at various seaports and use fueling barges as floating gas stations.

Right now, a four-day cruise from Miami to the Bahamas is around $440 per person, including taxes, for an inside state room. Online vibration monitoring adds to peace of mind for asset protection. This proven vibration system from Bently Nevada reduces non-critical trips and fits twice as many channels into your rack space than older models. With less than 5 days to install, you can increase starting reliability, availability, and improve safety—with GE’s upgrade to your hydraulic starter clutch. Bringing news and information about computers, people, inventions, & technology. Icon of the Seas will be delivered at the end of 2023 following the necessary sea trials.
Every piece of equipment can be monitored from the engine control room to ensure the cruise ship runs smoothly. There are several reasons for keeping the cruise ship engine room away from passenger areas. Ships that do use this type of power have usually solar panels affixed to their exteriors.
Cruise Ship Engine Power, Propulsion, Fuel
If you are ever in doubt, check with a crew member to ensure the water is safe for consumption. In addition to basic buoyancy principles, an engineer must also consider the ship’s average density. This means that the ship’s general open spaces must be considered on top of the vessel’s average weight, so the vessel remains “less dense” than the ocean’s (usually salty) water.
The same way works diesel-electric engines, yet they use a direct drive system, not a turbine. The output shafts, to produce electrical power, are connected to generators. On a side note, if the thought of diesel in the ocean disturbs you, there is some good news! Thankfully, more and more environmentally friendly options are appearing for cruise ships. For example, liquified Natural Gas (LNG) is an alternative method for powering ships that burns natural gas for power.
The ship will be shore power ready, use fuel cell technology, have waste heat capture and air lubrication systems, and even have one of the best water management systems at sea. Regardless of the ship’s size and type of engine, engines are extremely loud. Engineers compensate for this fact by incorporating sound reduction features and technology to keep the room well insulated, so it is less noisy for guests. On newer cruise ships, engine rooms are found on the aft of the ship and on the lower decks.
Modern cruise ships use diesel-electric engines, while newer cruise ships are moving towards more environmentally friendly solutions like liquified natural gas. As the world considers the effects that fossil fuels have on climate change, cruise ships have come under increasing scrutiny. Ship designers and engineers have begun coming up with new, more eco-friendly ship power systems to lessen the impact of cruising on the environment. Although no ships run solely on these power types yet, they supplement fossil fuel systems.
