This allows emerging problems and engine fault sources to be fixed before they occur. 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. 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.
What Are the Basic Functions of a Cruise Ship Hull?
In 1948 it was adopted by the International Maritime Organisation and is generally considered the current standard by which ships are measured for safety. The Act has been modified a number of times over the years with the most recent change going into effect in 2010. It is these guidelines that are primarily responsible for the change from steam to gas or electric turbine power. The engine rooms on a steam ship tended to be somewhat less safe than their diesel counterparts.
Gas-turbine cruise ship power system
A high end shopping and entertainment complex will be built around her. It is here that pistons hammer and crankshafts turn to propel the ship forward. It is the loud and oily place where the Chief Engineer and his team work around the clock to ensure that everything is running smoothly. It is the engine room of the ship that allows for the luxuries of air-conditioning, electricity, and plumbing on board cruise ships. MS Viking Grace is also the world's first ship with the energy recycling system "Ocean Marine" (developed by Climeon AB / Stockholm-based company).
Liquefied Natural Gas and New Fuel Technology
Backup generators are located higher up and also outside engine room spaces to isolate them from damage or fire. Wartsila's fuel engine package was specifically designed to reduce fuel consumption. The standard cruise ship engine can have a decibel range that exceeds 173 decibels.
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. Those who support the cruise industry point out that cruising has never been more popular. 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%. The next scheme shows the dual-engine powerplant (Wartsila) and propulsion (Azipod) of the cruise ferryTallink Megastar.
How Does Heat Escape from the Engine Room?
Onboard workshops are also a fantastic way to explore new areas of interest and develop new skills. From cooking classes to photography workshops, these interactive sessions offer passengers the chance to learn from professionals and engage in creative endeavors. Given that the hull’s outer surface is metal and has to withstand long-term exposure to saltwater, you might wonder why it does not rust. The ship’s outer surface is protected with corrosion-resistant coatings and paints. This acts as a water-tight barrier between the hull’s metal surface and the surrounding water.
How Big is a Cruise Ship Engine?
Usually, ships fill up at various seaports and use fueling barges as floating gas stations. Vessels use lower-grade diesel which tends not to burn as purely as diesel-powered road-going vehicles. Gas turbine engines (being aero-derivative) generate heat which is transformed from mechanical energy into electricity. To achieve this, compressed air is fired in a combustion chamber. Hot exhaust is made over a turbine that spins to drive mechanically a shaft.
Where Is A Cruise Ship Engine Located?
In fact, it’s loud enough that anyone working in the engine room is required to use hearing protection equipment, or it will damage their hearing. Most often, especially in newer cruise ships, the engines are located on the lower decks and towards the aft of the ship. They’re not all the way in the back, but they are in the mid-aft area. With a little help from a master mariner and ship’s pilot John, who has 47 years of experience in the marine industry, I’ll bring you the answers to your questions about cruise ship engines.
AIDA's LNG-powered cruise ships
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. But on average, the cruise ship, which is large in size like cruise ship uses nearly 250 tons of fuel per day, which is nearly about 80,000 gallons.
Her sister ship, Allure of the Seas will be joining her in 2010, making the Queen Mary 2 the third largest cruise ship in the world. It is powered by six marine diesel engines that put out 97,020 kilowatts (130,110 hp) which is used both to propel the ship and provide electricity to its passengers and entertainment facilities. The Oasis is also the first cruise ship to utilise Azipods instead of long screws with propellers on them. Azipods are propellers mounted to tubes which turn, making rudders unnecessary.
As the ship size increases, the demand for electrical power increases. Some large ships depend on two types of power source that gives power to the engine, one for propulsion and the other for electric power. A gas turbine, a wind turbine, generates heat that is transformed from mechanical energy to electrical energy.
It makes sense then that a cruise ship requires powerful propulsion systems to keep them moving. When you hear of a wind-powered ship, an old-fashioned sailing ship might be what comes to mind. This is not an image that is compatible with a modern cruise ship.
Modern cruise ships use diesel-electric engines, while newer cruise ships are moving towards more environmentally friendly solutions like liquified natural gas. Engine room tours vary from ship to ship but generally involve a visit to the main control centre as well as other areas of interest such as generators and electrical systems. It’s also common for passengers to be given protective clothing such as overalls, hard hats and safety glasses before accessing certain areas.

Gas-powered ships are faster, but most cruise ships don’t travel faster than knots. Modern diesel-powered cruise ships have between four to six medium-speed (500 revolutions per minute) engines. Each engine can generate upwards of 25,000 horsepower or nearly 18.5 megawatts. The engine rooms on cruise ships are located on the lower decks, between the midship and the aft. The engines aren’t quite at the back of the vessel but closer to midship. Passenger ships have come a long way from sails and steam engines.
