Cruise ships have several redundant systems to ensure the safety and security of passengers. If the generators fail to work during an emergency, cruise ships have an emergency battery backup to power the most critical systems for up to 24 hours. Royal Caribbean has brought back its behind-the-scenes tours that provide a look at areas of its cruise ships passengers aren't allowed to see most times.

Cruise News Recap: Carnival Hike, Overbooking, Stranded Passengers
This is found on the exhaust path proceeding the turbocharger on the way to the scrubber. Exhaust gas reaches a temperature of 663°F yet is continuously cooled using heat extraction until it reaches 86°F when it comes out of the funnel. If you are in the engine room while the engine is running, it will still be very loud regardless of what noise-reducing technology is used. To put it in perspective, those who enter the room are required to wear hearing protection. 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.

Fresh water is also produced by reverse osmosis to supplement the evaporator. Regardless of the size of the cruise ship, the engine in question is very, very loud. Fortunately, engineers can compensate for this by utilising sound reduction technology and designing the engine room of a cruise ship to be well-insulated. It is where crankshafts, pistons, and hammers rotate to make the ship move forward. The chief engineer and crew work 24/7 to ensure the entire ship operates smoothly. It permits luxuries onboard like electricity, plumbing, and air conditioning to function.

We recommend a rideshare service or taxi over a shuttle bus, though, especially in Fort Lauderdale, as the port is extremely close to the airport. Not only do prices of taxis and rideshares tend to be quite low from Port Everglades to the Fort Lauderdale airport, but you will not have to wait for a shuttle bus to fill up before leaving. Royal Caribbean ships primarily use terminal 18 at Port Everglades, although ships may dock at a different terminal if terminal 18 is in use.
It is from there that the captain and his officers command and maneuver the ship, keep watch for other vessels or potential hazards, and navigate through the oceans. The above photo shows Oasis-class ship propulsion Azipods (2 units) before being mounted onto the hull. The next photo shows the Azipods (both units) mounted on the hull. For example, if you sail to Canada and New England, you may find that the fog is so dense that the ship must sound its foghorn all through the night! If your cabin is towards the bow, you may be awoken by the sound of the anchor being raised and lowered. Or, if your room is by the elevator, you may hear lots of other guests chatting as they stagger to bed in the early hours of the morning.
Generators power all the vital functions to run a ship, like emergency lights, communications, and navigation systems. If the generator fails, then there are also backup batteries that can be used for short periods of time. 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.

Thanks to the insulation and sound dampening, you’ll only hear a slight “purr” if you’re near the engine room.
How much fuel do cruise ships use?
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. Wartsila's fuel engine package was specifically designed to reduce fuel consumption. Waste heat from the cruise ship’s engines is extracted by a series of heat exchangers located on the exhaust path after the turbochargers en-route to the scrubber. Typically, exhaust gas is approx 350°C, but it’s cooled continuously by heat extraction to approx 30°C when it emerges from the funnel. 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.
It has been used only since the late 2000s but is seeing promise as a more environmentally friendly method of powering cruise ships. Because the pistons are fired by a consistent flow of electricity rather than burning fuel, they move at the most efficient speed. Electricity is also used to pump cool seawater through the engines to cool them and prevent overheating. In the past, cruise ships kept their engines running while docked to generate electricity for shipwide services. Every cruise ship has an emergency generator to maintain vital electrical power in case of engine failure.
In rougher seas, other options may need to be considered for the safety of those on board. If it does happen, the captain consults the chief engineer to diagnose the cause of the malfunction. They will assess the severity and determine whether it is fixable. In newer cruise ships, engines are found on the lower decks toward the aft.
The electricity generated from the diesel-electric method can also be used onboard. It is converted to a lower voltage and directed to the cabins for passengers to use. Welcome to High Seas Cruising, your resource for exploring the exciting world of cruise ship travel.
They also understand the ship’s limitations, as well as its current status and performance. The captain often speaks directly with the engine officer, especially during emergencies. Towards the front of the bridge, you will often find a lowered observation and lookout deck. This area allows the captain and crew to get a clear view of the path ahead without blocking the view of crew members still at their stations. Typically, it is located towards the back of the bridge but retains a clear view of the path ahead.
Royal Caribbean vessels of Oasis, Freedom, and Voyager classes have pod-propulsion as many other big ships, which is opposed to the fixed traditional screws which push in one direction only. They need enough space not just for the engines, but also for the generators, the fuel tanks, the control room and the engine workshop. The standard cruise ship engine can have a decibel range that exceeds 173 decibels. This is frighteningly loud and well into the range in which hearing damage occurs quickly. However, thanks to insulation and other sound reduction technology, it’s not nearly that loud in practice. Perhaps you’re fascinated with the engines that power a cruise ship, or perhaps you want to know which cabins to stay well away from, due to the noise and vibrations of the engine.
