To put it in perspective, those who enter the room are required to wear hearing protection. A large cruise ship of 1,100 feet in length can hold between 1 to 2 million gallons of fuel. Engine rooms have insulation and sound-reducing technology, so it’s not as noisy. To prevent hearing damage, crew members must wear hearing protection when entering the multi-story engine room. Israel sharply curtailed traffic volume at these crossings in the first months of its operation in Gaza, leading to food shortages and warnings of widespread famine. The restart of aid trucking operations may reduce the need for a backup maritime aid corridor.

Diesel engines have greater fuel efficiency at slower speeds, and the high gas price compared to diesel makes them more costly to operate. Marine vessels that run on diesel power must carry exhaust-treatment systems and catalytic-reduction equipment to reduce the environmental impact of the ship. Diesel-electric engines are popular because of their ease of control, low noise, minimal vibration, and relatively compact size compared to other forms of propulsion. We’ll cover some of the most popular technologies used by cruise ships.
How Much Fuel Do Cruise Ships Use?
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. Vessels use lower-grade diesel which tends not to burn as purely as diesel-powered road-going vehicles.

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. MS Viking Grace is also the world's first ship with the energy recycling system "Ocean Marine" (developed by Climeon AB / Stockholm-based company). The system converts the excess heat (generated by engines and exhausts) into clean (emission-free) electricity with an annual capacity of 700,000 kWh.

Since we’re in the cruising business, we find this stuff fascinating, too. That’s why we interviewed Chief Engineer Rhea Wilson and her team to get the inside scoop on everything related to ship mechanics and operations. They break down how cruise engines work, where the water you’re drinking comes from, how cruise ships detect icebergs, how they avoid icebergs, and — yeah, a lot of other iceberg-related questions. If you knew nothing about ship mechanics before, that’s about to change.
Marine steam engines
Even so, they will not have anywhere near the capacity of the main engines and generators. They don't produce enough electricity to move the ship, and they can't even supply all the limited power needed in port, mostly because of space constraints. The ship is powered by a total of five Wartsila dual-fuel engines - three 12-cylinder (model 12V50DF, combined output 34,2 MW) plus two 6-cylinder (model 6L50DF, combined output 11,4 MW). Its propulsion system includes two Wartsila fixed-pitch propellers with twin propeller shafts.
How Big is a Cruise Ship Engine?
These massive tanks can be filled or emptied with seawater, which makes it possible to modify the ship’s center of gravity. Ballast tank adjustments are necessary to keep a cruise ship afloat and stable, so they are essential. The powerplant is controlled by ABB's PEMS (Power and Energy Management System), which also optimizes the onboard energy use.
These massive vessels can consume power up to about 50,000 horsepower. Engines are designed to move large propellers or produce enough diverted electricity to drive the propellers. Looking at a cruise ship, it is easy to wonder about the size of a cruise ship engine. So what happens when things go wrong and the ship is dead in the water?
Electrical Department
This protective coating must be inspected and maintained at regular intervals to keep the ship safe from corrosion. The AIDAprima ship's first successful test run for LNG supply was in Hamburg Germany on May 7, 2016. While berthed, the ship was successfully provided with LNG at all the itinerary's ports of call (Hamburg, Rotterdam, Le Havre, Southampton, Zeebrugge).
All the above have their specific line managers who report to the Cruise Director. The roles and responsibilities of some departments though can vary slightly from company to company. Shore Excursions department’s job is to make the shore-side trips of the guests to exotic destinations at various ports of call, as easy, fun, safe, adventure-filled, inexpensive and entertaining as possible.
The Bobo was carrying pontoons for a floating lighterage system, which was central to the delivery plan. The MSC logistics ship carrying supplies for the White House's planned Gaza aid mission has sustained an engine room fire and returned to the United States, according to the U.S. If you like the idea of enjoying everything a cruise has to offer, but want to get more involved, perhaps you'll enjoy signing up as a guest speaker. Are you curious as to how all those cruise meals just keep rolling out, often 24 hours a day with room service, seven days a week? Between feeding different palates and ensuring dietary restrictions are met, cruise chefs are responsible for a great deal. As others have noted, no, you won't get into the engine room itself.
You may find that the vibrations cause the coathangers in your wardrobe to rattle, which could disturb your sleep. Modern cruise ships carry a gyro compass and a magnetic compass. The gyro compass consists of a fast-rotating disk, usually positioned in a gimbal. It is a non-magnetic compass oriented parallel to the axis of rotation of the earth and thus indicates the north-south direction. The signals emitted by special navigation satellites are picked up by the cruise ship through a special antenna.
Without a cruise ship engine, these vessels would be nothing more than a floating hotel. They would drift aimlessly at sea and would lack any form of propulsion. Looking at the sheer size of these vessels makes one wonder how large an engine needs to be to maneuver the ship successfully in water. The electrical power created by the engines drives this big azipod motor which turns the propellers, and pulls the ship forward. Basically think of how a jet engine pushes air across a plane wing — that's how an azipod and propeller pushes water across the rudder and drive/steer the ship.
