Inside One Of The BIGGEST Cruise Ships In The World

[Music] foreign [Music] decks of the transatlantic giant named Symphony Of The Seas comfortably accommodates six and a half thousand happy passengers they will enjoy an incredible Adventure a journey around the Caribbean [Music] this is a quiet and peaceful place now you won't find Pirates here unless they're from the entertainment team of course several days of Unforgettable rest await passengers but throughout their Voyage they won't ever see the hundreds of devices machines in sophisticated bits of engineering technology nor that nearly one and a half thousand people on the lower decks of the ship that are part of a crew of more than 2 000 who will make their vacation truly comfortable and saved Symphony Of The Seas is in fact the largest passenger ship in the world today it's even been recognized in the Guinness Book of Records but what do we mean by the largest it's not actually about the size when it comes to ships another liner in the same class Harmony of the Seas is longer than Symphony by several centimeters but the symphony has the largest displacement the amount of water that is displaced by the ship due to its volume remember Archimedes principle while the symphony has a displacement of 228 000 tons that's equal to five Titanics a giant like this isn't able to enter just any port in Russia for example there is only one that can accommodate this ship in Vladivostok while the most advanced places in this regard are countries in Asia Europe and of course the United States [Music] Port Miami Florida's major Seaport here is its cargo terminal all in all it has rather modest traffic figures about a million containers move through here per year so we've got maybe a dozen cranes and just a couple of ships docked here at the moment this isn't what this port is famous for of course that would be something else that I'll show you right now here is the world's largest Passenger Terminal for cruise ships here behind my back that's not a multi-story building you know it's the stern of the ship named Symphony Of The Seas six thousand people are boarding it right now and in the span of just a year five million 600 000 people pass through this Passenger Terminal that's more than the entire population of Miami it's not so much that Americans are particularly fond of cruises as it's that Miami is ideally located Mexico Cuba and the Bahamas are all just a few days travel from here that's why this port was chosen by several major Cruise companies to be their starting points you can see that right now six different liners are all preparing to leave and they belong to four different operators but Symphony Of The Seas immediately stands out from the others due to its incredible size [Music] at about the same time when a shipyard in France began to build the ship itself several thousand miles away from Europe On a completely different continent right here in Miami they began to build this terminal again essentially it turns out that the ship wasn't built to fit the size of the port but the port was built to fit the size of the ship the main feature of this terminal or maybe I should say the main art installation in this terminal is these two rotating propellers which are exact copies of Symphony Of The Seas propellers they each have a diameter of 50 feet and the weight of the real ones is 200 tons each but these are of course a bit lighter by the way the ship doesn't have two of these propellers but three they're mounted on potted propulsion systems so-called azipods those are made up of huge pods which are suspended from the bottom of the ship at the stern they are capable of rotating 360 Degrees meaning as a pods provide the giant vessel with easy and quick maneuverability I will show you in more detail how all this works in the second part of the episode but for now I will only say that these azipods were manufactured in Finland and then sent by sea to the French town of Saint nazare the home of the shipyard where the vessel was built in general Symphony Of The Seas is a huge construction set consisting of hundreds of thousands of Parts which were manufactured in dozens of different countries located on different continents so it began to unite people from distant corners of the world even before the first passengers of various nationalities ever stepped on board [Music] ing a ship is very much like boarding an airplane these gangways while those who often fly they know that they are almost identical to those in airports well maybe these are a little wider only planes have a maximum of two such gateways well the largest airliners might have three but here there are five of them and another interesting peculiarity those who fly know that boarding of an aircraft starts about an hour before departure and stops 20 minutes beforehand but since 6 000 people have to go through here onto the Ship boarding begins six hours before departure so that everyone has time to make it on board this is why cruise ships almost always depart in the evening all day long passengers come on board get used to their cabins and then closer to Sunset the gangway is finally pulled back the doors are all closed and the ship rolls away from The Quay wall thanks to those azipods that we mentioned earlier and an additional tail rotor Symphony Symphony Of The Seas could help maneuver by itself without the help of any tugboats only a small Coast Guard Patrol boat moves ahead of a dispersing small pleasure boats and ferries out of the liners path this moment already routine for the crew is always quite exciting for the passengers who at the moment of departure always pour out onto the upper decks after all the sea and even more so these calm Oceanic Waters aren't anything like railroad tracks and these gigantic ships are actually seen off in a very different way from trains yeah however the passengers will hardly have time to feel any separation woes on the ship this Giant floating city is designed to be fun and entertaining foreign ER is 1053 feet long more than three soccer fields its width is 216 feet and in this huge space there are 28 restaurants three swimming pools 10 jacuzzis a theater equipped with the most complex Broadway Machinery in ice rink A Tropical Park a water park a fitness center a casino and many shops and boutiques that constantly keep tourists in a State of shock and awe and continuous happiness it is somewhat reminiscent of something out of a fairy tale a place where you need only eat sleep and drink when you look at the map of the ship these are posted everywhere here you get the feeling that the ship is some kind of toy yes there's 12 passenger decks yes it says 2 750 cabins but what do all these numbers mean you only start to get a sense of it right here in the elevator Atrium just take a look six high-speed elevators transport thousands of people to a height of 229 feet Around the Clock and at the same time all this is now moving at a speed of 30 miles per hour in the direction of Mexico incredible more incredible is the fact that the ship is directly controlled by only three people while it's in motion and among them there is no boatswain no Skipper no Helmsman even the captain himself isn't on the bridge all that often [Music] today the people who control the ship from here from the captain's Captain are no longer what you might imagine Sailors with tough salty weathered faces they look more like office workers and this place resembles some kind of control room or something and here's my biggest disappointment this is the captain's chair there's no steering wheel the ship is controlled by two special joysticks they're called anti-mice in general everything is technologically advanced safe highly scientific and completely lacking in Romance For Heaven's Sake you no longer have to pour over maps to plot a course the navigation system stores all the necessary routes in its memory the computer plots the path taking into account the shallows reefs and other features of the typography of the seabed and satellites track the position of the liner an operator just needs to plug in the arrival time for the next point on the route and the computer will even calculate the speed with which the ship could move it's kind of like autopilot the next time a person will need to directly intervene is the moment the ship approaches support [Music] I will remind you again is 216 feet therefore side mirrors here clearly wouldn't cut it for parking so when parking while when Mooring that is they use a special Mooring console here it is by the way it sticks out from the side of the ship a bit you see it kind of hangs over the side for better Sidelines there is a second identical control panel on the other side of the liner either the left or right one can be used and that's determined by which side of the ship approaches The Quay wall the compass and binoculars found here are likely more of a tribute to Maritime tradition than anything else Mooring here again takes place with the help of space satellites in GPS when the ship finally gets into the correct position it is you might say tied to the pier with special ropes this is almost the only step of the whole docking process that looks pretty much the same today as it did several centuries ago the huge ship is held in place by means of 22 of these extra strong ropes each about 5 inches in diameter right now they're stretched like piano strings they even vibrate a little and here's something amazing if you knock on the Rope you'll have to take my word for it it's very solid it feels like there's some kind of metal core inside but in fact this is not the case the Rope is woven from a variety of synthetic threads they're very strong they have a high elasticity coefficient they're able to handle the highest levels of stress but at the same time as you can see the Rope is already quite frayed despite the fact that it's less than a year old it'll be changed soon previously Mooring ropes or to be more nautically accurate Mooring lines were woven from hemp the use of polypropylene fibers is a more recent development these ropes turned out to be much stronger and what is even more important they don't absorb moisture so they're much lighter curiously on these ropes from the 21st century these shields from the 16th century if not earlier are still put to use they're called rat guards and are needed to keep rats from the shore from running up the Mooring lines onto the ship today this small Mexican Port has a real full house three cruise liners arrived here at the same time and all the birth walls are occupied here Symphony Of The Seas six thousand tourists Norwegian Dawn about four thousand and lastly a ship called celebrity reflection there are about five thousand more people on air in total about 15 000 people are coming ashore all at once this by the way often becomes a serious headache for the staff of the ships in the evening when tourists come back here relaxed we'll say after sampling some tequila they have a bad habit of trying to board the wrong ship but there haven't been any cases of someone sailing away on the wrong liner not yet the stewards and representatives of the Port Logistics service worked like clockwork and don't drink tequila just like the other 2000 crew members of Symphony Of The Seas who unlike the passengers don't go ashore when the vote docks while tourists are exploring local attractions on the lower decks preparations for the main task of the day are underway cook ing dinner for 6 000 passengers before they get back on board and for this you first need to bring up several tons of products from the storage area to the galley [Music] usually the entire selection of products for the cruise is loaded onto the ship at the port of departure the liner can only take water on it into Rim stops and even then only bottled water they are very afraid of the possibility of food poisoning here since thousands of people live compactly on the ship a simple case of E coli can turn into a real epidemic in the speed of just a few hours and even putting that aside not all countries can provide products of the high quality that Symphony chefs require [Music] all the refrigerators and storage boxes here open automatically with the Press of a button but there is one door whose button is behind a lock thankfully I have the magic key you've probably already guessed what's behind this door here it is the holiest of holy of Symphony Of The Seas storage area here are several thousand bottles of elite red wine [Music] milk meat Seafood vegetables Frozen products fish all of that and more is stored in the dozens of other refrigerators anything and everything that might be needed to prepare the 350 different dishes that can be found on the ship's restaurant menus of all the food stuff stored on the ship only two products are honored with having their own private refrigerators well simply because they are the most consumed items first we've got bananas here are plenty of boxes with yellow ones and there are also boxes with green ones they will finish ripening during the cruise and the second product is the most popular what do you think it is I'll show you now eggs 120 000 eggs are eaten on board every week moreover bananas and eggs are as economists and logisticians say Goods of inelastic demand their consumption rate and hence the required plant amount is easy to predict things are more interesting when it comes to the rest of the products on board a specially developed computer program analyzes the number of passengers in their nationalities even before setting a sale and depending on that information it gives recommendations on how many of this or that product you need to take with you on any given voyage for example if there is a large number of Latin Americans on board more meat and spicy foods will be added to the menu if there are more Asians they'll reduce the amount of dairy products and if Indians are prevalent they will increase the number of curry dishes but at the same time they will bring less beef foreign Delicacies of any hope Cuisine is of course the Atlantic Lobster here he is such a handsome guy this dish by the way is not cheap therefore it is very rare and even here it's cooked well not all that often it's a one-of-a-kind item one might say made six thousand times every day [Music] each of these workers they are mostly Filipinos working here shells about 500 lobsters a day [Music] those of you who I've ever shelled for example crayfish can imagine how much work this entails [Music] on just three decks more than a thousand people are employed in this huge floating kitchen 250 of whom are professional restaurant chefs fry boil flambe Satay and whip Around the Clock Indian shifts take breakfast rolls for example 12 000 of them are baked here every day in fact the responsibility of the cooks here is enormous the clients on the ship are very demanding the products are expensive and the cooking portions are gargantuan therefore the slightest mistake in the proportions of ingredients can cost tens of thousands of dollars well for example tomato soup 160 liters of it if it's a little bit overcooked or under salted that's it eat it yourself since no one else will seating and serving several thousand people in the liners restaurants at the same time is a separate logistical task and they strive to make it so that customers don't have to wait more than 15 minutes for an order several hundred waiters of 50 nationalities cope with this task each of whom must speak at least three languages and bartenders should know at least five well technically there was an exception made to that rule in general everything on this ship suggests that this is a high-tech structure created according to the latest leaps of science for example in this bar drinks are mixed well probably in the most Progressive Way on the planet all you have to do is make your choice on the tablet screen the so yes we confirm and e and that's it we go up to the bar and that's it enjoy it another high-tech installation though it doesn't seem like one at first glance is a huge park with its own microclimate which is laid out in the central part of the liner here among the Shady alleys is serenaded by the songs of specially brought in crickets and frogs it's easy to forget that you are actually somewhere in the middle of the ocean in this park not many oh just no less than 10 000 plants have been planted from rose bushes and orchids to lemon trees and all this grows here blooms and flourishes what's the secret I'll show you here for every plant maybe I'm not being generous enough well for almost every blade of grass practically there's a special tube placed next to it which from time to time that you will probably see it yes fresh water is sprayed out and not just water now I'll show you the irrigation station here through these pipes four tons of specially prepared water are pushed every week here's the main secret here in this blue Barrel fertilizer is kept in here water passes through it carries away some of the fertilizer and carries it to the plants [Music] so thanks in fact to this seemingly unremarkable little device this whole huge blooming Park exists another secret of the permanently Green Park is its honeycomb structure there is no Solid Ground here all the plants from the trees to the grass are inserted into special cells in separate segments small plastic boxes it turns out to be something like a huge puzzle if one of the segments suddenly starts to get sick or dry out it's simply changed out for a new one upon arrival at the Home Port [Music] wall of vertical Landscaping in the ships of Central Park follows the same principle The Gardener who turns out to be a bit of an industrial climber as well simply climbs in the bucket and changes out the parts of the wall that he doesn't like and discards the old segments there is no time for sentimentality nothing should prevent people from enjoying their time here and being filled with joy remember what I said at the beginning that this episode was about a cruise ship without romance and without leaving anything out in the next episode of Monster Machines why doesn't the ice on the only floating ice rink in the Caribbean melt well you know it tastes like the most simple ordinary Russian snow how can 1 500 sheets be washed and ironed in one day I want one of these for my house only thing is I'm afraid it won't fit in my laundry room the Symphony of the Seas have enough lifeboats at the event of a disaster how were the engines of this liner which consume three tons of fuel per hour arranged and how do they work fifth grade physics at work are the largest ship in the world what is a 19th century Telethon doing on a super modern ship a low bridge and how can 30 000 plates get washed in two hours Mr Clean would be impressed see all this and much more from the anatomy of the world's largest cruise ship in the next episode in the first part of our look at the anatomy of the largest passenger liner in the world we told you about and showed you why is Miami the home of this monster essentially it turns out that the ship wasn't built to fit the size of the port but the port was built to fit the size of the shim who are the people who run this giant and why is there no Helmsman on the ship this is the captain's chair there's no steering wheel what room on the ship is the most secure and guarded here it is the holiest of holy of Symphony Of The Seas storage areas and how many cocktail recipes does the least talkative bartender on the largest ship in the world know you're not much of a conversationalist all this was in the previous episode and now we have even more about what's hidden inside this monster a cruise ship without romance but with science [Music] thank you and what could be less romantic on a ship than the Machinery room in the lower part of the ship where tourists aren't allowed day and night there's the Roar of Machines working in the semi-darkness and these are what makes this entire giant City on water move Symphony Of The Seas is six diesel engines a total power capacity of more than one hundred thousand horsepower for a point of reference that's approximately the power capacity of 1200 cars however not even close to all of this energy is spent directly on moving the vessel the ship consumes colossal amounts of electricity for example for lighting there are about 140 000 light bulbs on the liner also electricity is spent on the operation of air conditioning systems and on the production of large quantities of water vapor yes yes despite the fact that Steamers and steam engines are a thing of the past modern liners still use steam a lot of steam no it of course no longer rotates the turbines as it did for example in the Titanic but steam is needed for more domestic purposes it's a simple method for heating the water into showers and bathrooms and it also Heats different spaces when necessary however those aren't its main function steam is necessary for the heating systems for the huge Fuel and oil tanks and it's also used in fuel oil separators it's consumed by the turbo drives of some pumps and well if it's necessary for several other important machines on ships it's consumed by the turbo drives of sump pumps and while it's still necessary for several other important machines on ships even in the 21st century moreover it must be perfectly clean so that impurities don't build up on the walls of the steam lines therefore it is Created from distilled water but where do they get such large amounts of distilled water it's produced right here on the ship using giant distillers here they are there are three of them the principle of operation is very simple while it's basically a big tea kettle this is where water from outside comes in here it's boiled steam accumulates in the upper part of this chamber into the sea salt settles down at the bottom so after a while oil overheated steam there's a lot of it enters this chamber here it condenses and as a result the finished distilled water is drained through the pipe and the leftover salt no it's not used in the kitchen they just throw it back into the sea several tons every day foreign this does not harm the environment in the slightest since in essence they're only turning the ocean's own salt back to itself while keeping the moisture on board then the distilled water here it goes on to be filtered and then it enters the boiler well again the principle of its operation is about the same as that of the boilers which many of us have in our bathrooms at home there is a small burner here at the bottom and a tank of water on top a very large tank five tons and it starts boiling in just a matter of minutes [Music] in the end the resulting steam is used for its intended purposes moreover part of it when it condenses again is sent back to the boiler this is the so-called reverse cycle but most of it is irretrievably lost and therefore the reserves of distilled water have to be replenished all the time it's also needed to freeze an actual skating rink on the ship here you can skate during the day and watch an amazing ice show in the evening that includes a number of Russian figure skaters [Music] foreign [Music] by the way the ice here is to be very high one might say Olympic quality the ice on the rink measures in at about 3.5 inches thick well surely many of you have seen an ice resurfacing machine on TV or maybe even in person they've got the exact same kind here though maybe it's a little smaller than typical ones by the way since this ice is Frozen from desalinated seawater it doesn't freeze quite as well and according to the skaters this ice is softer than that on which they are used to performing on on land to be honest it's hard for me to imagine how ice could be soft but what is absolutely certain is its incredibly clean distilled I even give it a taste but it was really nothing miraculous just your typical snow [Music] the total weight of the ice in the arena is several tons and the refrigeration unit is needed to freeze it again it's about the same as the one used on professional skating rinks and professional Arenas well this one might be a little smaller it's located as you would expect in the area under the stands the principle of its operation is very simple through special pipes here they are wrapped in thermal insulation water and refrigerant with a temperature of 14 degrees Fahrenheit are pumped to the arena this freezes the ice layer by layer it takes about five days to prepare the entire ice rink the owners and designers of Symphony Of The Seas claim that this ship is not only the largest in the world but also the safest there are so many different safeguards in place in its control system that it is argued it's almost impossible to leave the liner into disaster even if you were to deliberately try to do so still in the event of an extreme case there are means of evacuating the ship on board they have to accommodate the evacuation of all passengers and crew if something were to happen these lifeboats to match the ship are the largest in the world each has a capacity of 370 people there are 18 of them on the ship moreover they are kept fully prepared at all times their fuel tanks are filled they have a cruising range of about 155 miles there was a special supply of dry rations and water on board and special sealed boxes in the event of a disaster there would be no time to bring it all from the ship in general everything is thought out to the smallest detail this Unsinkable and waterproof plastic jar for example contains signal flares in addition to the huge boats there are also many rafts that inflate themselves in the water and several of these high-speed rescue boats they are used to coordinate action and quickly help people who find themselves in the water the crew must participate in evacuation exercises at least once a month this vessel has never seen a real red alert but thanks to constant training 2 000 crew members are ready for any turn of events 24 hours a day 7 days a week the ship also has its own waste recycling plant here it is this for example is a machine for pressing cardboard Packaging here cans are collected [Music] then they are all crushed into these large bricks [Music] cellophane is processed here at first glance it is a little paradoxical how they deal with glass bottles I'll show you now they are simply broken into little pieces so that they take up less space and they are sorted as follows we have a big bag with dark glass here we have broken transparent bottles and here we have green glass and here's what's surprising as is everywhere else on the ship in this waste recycling shop everything is kept perfectly organized there isn't even an unpleasant smell here the creators of this ship seem to have a thing about cleanliness and environmental friendliness in a good way of course for example the liners engines burn several tons of diesel fuel every hour but at the same time not black not even blue but exclusively white smoke comes out from the symphony's exhaust pipes all thanks to scrubber cleaning well if to simplify it as much as possible the exhaust gases are washed with sea water this dirty water is then maintained and stored in special tanks until the ship arrives at a port and only carbon dioxide with a minimum amount of soot and impurities is released into the atmosphere scrubbers and engines are managed from this control room it's located in the very center of the ship almost at the water line itself therefore there are no huge Windows to be found here like on the captain's bridge but there are 51 monitors which display thousands of different parameters the largest touch screen control panel even had to be hidden in the ceiling here is already pretty cramped without it there's a special emergency phone in this control room while there's a telephone for singular emergencies its peculiarity is that it will work in any case even if say God forbid of course all systems here completely fail and all power is lost by what means I'll show you now good old inductive coil this technology well I don't know it's probably around 120 years old and it's very strange to see it on this Ultra Modern ship but technology such as this is sometimes the most reliable hello Bridge apart from that the equipment in this control room is of a quality comparable to NASA's flight Control Center and the whole vessel is practically a spaceship sure they're not jet but diesel fueled V engines but each weighs about 200 tons two of them are 16 cylinder four more are a bit smaller with only 12 cylinders thank you these Giants were made in Italy and then they were sent by a special Convoy first along blocked off roads and then delivered by sea to a shipyard in the French town of saint nazare building each of the six fiery hearts of this monster was such a difficult technological task that we decided to show it to you in more detail that's why we're taking the reverse path to the engine from the Caribbean Sea into Miami through France to the Italian industrial Port of Trieste [Music] the company that makes the world's largest Marine engines in Italy is actually from Finland it's called vyart cilia it got its name in honor of a small Finnish village where this business once originated curious but today the urban type settlement in the yardcilia station of the October Railway are part of the sortavala region of the Republic of corellia a typical Russian single industry town with a modest budget at the same time darsilia has an annual revenue of several billion dollars the engines two of them consists of several thousand Parts some of them are made right here in Trieste some come from subcontractors forged blanks for example are sent from a metallurgical plant in the Czech Republic the so-called connecting rods come here to the plant in this form crudely forged very coarse to the touch here they are then installed in these machines they each weigh 330 pounds by the way many of us when we were kids not everyone of course in shop class did something similar carving out various objects it's about the same here only the size is much larger and the accuracy is very high as a result the connecting rod is worked too well just to a mirror shine everyone who has ever gone over the engine of their car seen the Pistons immediately recognize them while this one believe me is exactly the same well a little bigger this weighs about half a ton and the volume of the cylinder in which it works is 6.5 liters that by the way is a bit more than the total volume of my car's engine well all right not a bit more several times more and this I repeat is only one cylinder and in two of the engines on Symphony Of The Seas There are 16 cylinders just like this one and the main difficult to hear is that huge parts that sometimes weigh several tons must fit together perfectly after all there is so much force and heavy loads involved that the slightest deviation or inaccuracy can send the engine off the rails and in the open sea that can threaten the catastrophe therefore manufacturing margin errors are as severe as with Swiss watches [Music] the way using the crankshaft as an example you can easily understand the principle of operation of a piston engine look in this position for example the Piston would be in the upper position and this crank pin is also up at the same moment the other piston is in the lower position and the crank band respectively is at the bottom thus the Pistons move up and down and the shaft rotates everything is very simple but the most amazing thing is that this particular shaft weighs 25 tons its length is 26 feet and it's made of one single solid piece of metal just unbelievable by the way there are only a few metal Lads in the world that can carve a 26 foot item like this from a multi-ton bar of high strength alloy steel the Turner's worst nightmare here is to screw up even one detail the crankshaft is worked on for several weeks and it costs more than a million dollars ultimately after numerous checks and tests the crankshaft and thousands of other parts are sent to the assembly area in a few more weeks the engine is finally ready and now tests awaited if everything is in order the engine is rolled back onto the ship all technical fluids are drained and it's checked again and again in the testing chamber the engine has already been checked out by numerous automated computer systems sensors and so on and so forth but no one has done away with the good old visual control test everything here again is like in a car we open the hood and look inside perhaps the most important difference between this engine and a car engine is that there are 12 of these hoods or rather viewing windows behind each of these windows is one of the cylinders and valves connected by a connecting rod to the crankshaft if you wait for the oil to drip down from the parts you can simply see with your eyes if any jams or other metal defects have formed during the tests when at this stage the inspectors give the go-ahead the only thing left is to pack up the engine and send it to the customer but that's easier said than done anyone who has ever well transported say a dresser knows that the most necessary thing to get that done are duct tape some styrofoam oh here we have some wow and a lot of bubble wrap when moving a finished engine everything is about the same all protruding parts are carefully wrapped with these foam Corners sealed with tape clean wrap and so on and so forth well in general everything is the same as when moving furniture There was a slight difference though the weight of this dresser is 180 tons it takes a week just to get it ready for transportation by the way at the same time Road Services aimed a special platform the only one in Europe that can support such a weight in size are being prepared for the Giant's move to the port only here at the very end in the finished goods Warehouse can you begin to understand the true scale of this giant engine its height is about that of a three-story building it weighs several hundred tons and generates the amount of electricity that would be needed for a small Moscow neighborhood the actual biggest mechanical heart in the world of the world's biggest cruise ship let me remind you Symphony of the Seas has six of them and although at the same time even at full speed usually no more than three of them are working the fuel consumption is still massive and that's why the company that owns the ship uses a little trick at the starting point of the journey in Miami they take on board only as much fuel as is needed to reach the next Port where fuel is cheaper and when they're already in Uruguay or Mexico for example the liner is filled up with diesel all the way thanks to this the ship owner manages to save several million dollars per season however there is one caveat for some reason the fuel from these countries often contains water by accident of course I'm sure but this is unacceptable for the engine therefore all fuel is cleaned directly on the ship before being fed into the combustion chamber but how can several tons of fuel be cleaned per hour and when moving at full speed too and here centrifugal force comes to our Aid fuel enters these separators which are in essence huge mixers and it's spun at a Breakneck speed what happens in there water which is heavier is forced out to the walls and the oil product as the lighter portion accumulates in the center and then enters the engine fifth grade physics will work on the largest ship in the world at the same time the fuel in the separators is also heated that makes it more runny and it therefore Burns better by the way the liner has an electric Drive no it's powerful internal combustion engines do not directly rotate the ship's propellers they spin generators that generate electricity and then along the high voltage lines hidden in the bowels of the liner the current travels to the electric motors which spin the propellers this diesel electric circuit makes the vessel more maneuverable after all an electric motor unlike a piston one can stop and change the direction of rotation almost instantaneously and it doesn't need a gearbox the motors together with the propellers can also rotate 360 Degrees around their axis therefore it becomes very easy to operate the liner however even the most high-tech devices and numerous automatic safety systems are not able to 100 protect the ship from basic human error three weeks after we filmed this episode in the same Mex import where Symphony Of The Seas stopped for an afternoon two cruise ships managed to collide foreign oh my God there were no casualties both ships even continued on their voyages but still this situation once again reminded me that regular emergency evacuation drills on the ship are not at all excessively precautionary however maybe no less dangerous than a collision with another ship would be a situation in which six thousand passengers were left hungry they almost seemed to fear this even more here the 350 Exquisite dishes on the menus of 28 restaurants will satisfy even the most demanding customer [Music] we already showed you how this Monster's kitchen works in the first part of this episode and perhaps at this point the question occurred to you how can you quickly wash a large number of plates mugs glasses and Cutlery after dinner [Music] on this ship in general all technological processes that can be are built on the principle of a conveyor belt well this is logical of course because this is one of the most effective forms of labor organization and here in the kitchen the dishwasher is also one huge conveyor machine come with me I'll show you sorry dirty dishes are being loaded from that side and clean ones are already coming out here the whole process takes less than one minute extremely fast Mr Clean would be impressed there is no other choice because after every dinner about 50 000 dishes have to be washed and that's not counting the kitchen utensils though it may seem like less than a critical machine the dishwasher on the ship is actually such an important unit that it has a twin backup in case the main one breaks another one of the liners important machines is the washing machine it was built to special order and installed in the bowels of the ship at the time of its construction at the shipyard a whole two technical decks of Symphony Of The Seas have been given over to laundry here about ten thousand towels are washed every day they also try to automate this process as much as possible housekeepers collect dirty towels from the rooms sort them by color and send them to the laundry decks here they are loaded into this receiving bin homeowners know that the most difficult thing to iron are sheets and duvet covers it's really quite time consuming to do with an iron but here you have to iron 2000 sheets every day and that's why they installed this machine here it not only irons the sheets but also this is the most amazing thing I'll show you now it folds them look in an ideal way not just anyone can do that in short I want one of these for my house only thing is I'm afraid it won't fit into my laundry room okay foreign the laundry employs several hundred people there's more than a thousand in the kitchen dozens more are in the engine room and on the bridge a huge Army of the crew invisibly makes every second of this day of the passengers on the ship Unforgettable comfortable and safe and yet the passengers themselves will never see most of them only service Personnel who are in direct contact with tourists are allowed to climb up under the passenger decks that includes waiters Maids bartenders sales people hairdressers and other staff others sometimes for several weeks at a time don't leave the depths of this monster and go out into the sunlight at all but keep in mind first of all they are well paid for it and second at the end of the day they work on the largest cruise ship in the world and although they can't take in the incredibly beautiful sunsets of the Caribbean Sea from their own balcony Behind the Walls of their cabins which are located on the lower decks you can hear the rush of water yes I promise that it would be a story without romance but still [Music] thank you
