Moving a Wonder: The Engines of Allure Bring Smooth Sailing

Moving a modern wonder like Allure of the Seas through the ocean takes a lot of power. See how the complex combination of six engines provides 135,000 horsepower and a smooth ride for guests onboard.

[@bobcarter4343]

I toured the engine room of one of the smaller RCL ships and it was amazing! Bunker oil had to be heated prior to use to thin it out. So clean these engine rooms. Engines are taken out of service while underway and completely rebuilt by a special crew when needed. Amazing operation. My thanks to RCL for the tour.

[@chelasca]

Hernán Zini, one argentine captain, i feel proud of one person of my country leading this kind of ship.

[@3ne2nr4life]

Capt Zini, nice to see you again after all these years dude......... We worked on the Freedom of the Seas....

[@Mattsana]

God, I just love this... Zini. This is directly to you. You're living my dream! haha I can see how happy you are having that job :)

[@wendykoek6757]

Oh nice love hearing a Captain’s voice

[@fntcyfctry]

Those engines do not directly propel the ship, they run genrators which run the electric pods.

[@renepinto8986]

i need to travel in that ship soon

[@Jemppu]

Ship built literally next door to my place at Perno ship yards :)

[@alejandrofallas9734]

Un argentino al frente de un gran crucero que bien.

[@slownecks7763]

Cheif Engineer is Norwegian, you see that in his name and in the poor english. On the seven seas there is A LOT of Norwegian Officers, thats because we are a quite good kind of people for that job, and it its in our DNA to be at sea. And the Royal Caribbean is partly Norwegian cause there was a Norwegian in the main founder. And The Norwegian Cruise Line is Norwegian was Norwegian, but it was founded in USA and owned by Americans. Same goes for Carnival Cruise Line.

[@deasos16]

anyone know why they used footage of Oasis of the Seas at the end of the video? They couldn't find any footage of Allure?

[@hop208]

I noticed solar panels on the roof during the fly over at 2:12. I wonder how much power they derive from those and what they are used to power.

[@wendykoek6757]

Wow how good is that must be much the same on ovation too

[@kristenburnout1]

He is speaking english with a very norwegian accent. :)

[@13295n]

:) got a good idea now of a current time ships engine system

[@ecoRfan]

It LOOKS like solar panels, but what I was saying is that the system on the Allure in terms of technology is the most advanced in the industry. All the computers, screens, controls, and such. It's a wonder, an allure within itself.

[@elc0n]

He es from my country Norway :)

[@Daniel7681]

Captain Zini looks likes he's about to fall down due to lack of sleep... lol He's got the best job in the world though.

[@bonkeydollocks1879]

More views of the engines please

[@mr.t8624]

So what was the thumbnail?

[@Mar2623]

So what´s the point of this flooding tower block?

[@pressdesign]

1:14 Thumbs Up for ABB ! ;0)

[@whitebaron1993]

@Des Thompson In this case redundant is the correct term. It applies to the fact that there are 'back ups' built into the ship As he says 4 engines could completely fail and the ship could still return to port In doing this they make the ship the safest place to be so if there is causalty to the vessel it can return to port instead of having abandoning ship.

[@thebunnisher109]

***** With background as a Naval Architect / Marine Engineer and Chief Engineer, redundancy is the term used in the industry, and it's been the saving grace of our operations many times over.

[@thebunnisher109]

You are right I was not trained specifically in linguistics, but do not have to be in this case. Per Merriam-Webster: "A part in a machine, system, etc., that has the same function as another part and that exists so that the entire machine, system, etc., will not fail if the main part fails". Likewise, the industry term is redundancy and it applies to the multitude of ever-present ways to accomplish the same task. There are fail-safes in every regard. I've run a ship with half of my ten engines operational, broken propulsion control system, loss of mechanical lube oil and controllable-pitch pressure, no shaft brakes, and a flooded machinery space.The ONLY way we were able to continue operating was by virtue of redundant systems. At least two of everything onboard, with multiple variations of each.

[@webnut2000]

***** ENGINEERING (of a component) not strictly necessary to functioning but included in case of failure in another component. en.wikipedia.org/wiki/Redundancy_(engineering)

[@johnburns4017]

***** redundancy in engineering means backup. The term is used in computing also. It does not necessarily mean a system lays there unused just in case. The whole lot can be used and if one fails the other can cope. You see it in ships engines, boiler in large buildings, computers that run companies, etc.

[@johnburns4017]

Yes, I know what redundancy is. A term have have used most of my life.

[@johncharlesmugen745]

megaships could break a storm. bt for the safety of all passengers they where tracking the storm and set sail through its tail. allure and oasis are the biggest ships in the world. .no doubt about it.

[@dodgingdaniel]

is that a helipad i saw in the front

[@thomasnixon7702]

So it is diesel-electric drive. The props are turned by electric motors?

[@johnburns4017]

Thomas Nixon The diesel engines turn only generators. Three swivelling Azimuth props with electric motors drive the ship. Azimuth can increase efficiency by 25%. The Queen Mary 2 has also two gas turbine engines under the funnel in soundproof rooms to generate power, along with three diesel engines down below. Diesel engines are old hat in marine technology. A number of Swedish, French and Japanese submarines have Stirling engines that are very quiet near vibration free, being far more energy efficient than diesels. Stirlings are external combustion which means they are far cleaner in emissions. Far cleaner natural gas can be used as the fuel to eliminate dirty diesel. Stirlings are ideal for ships as they need lots of cooling and sea water gives that. Air conditioning chillers can be absorption, which only needs heat to operate, supplemented by smaller motorized chillers. Waste heat can be used to cool and heat the ship. I have no idea why Stirling engines are not upscaled and used in ships. Ships have a long way to go yet for greater efficiency. The fact is the technology is here to greatly improve matters and has been for a long time.

[@johnburns4017]

***** It is "very" fuel efficient. The diesel engines are designed for maximum efficiency running at a constant speed. Engine efficiency is guaranteed no matter what speed the ship is moving. The Azimuth (azipods) gives maximum manoeuvrability, which direct drive cannot give.

[@paullangford8179]

+JP JP You only need to run enough engine to give the speed you want. So quite often there are diesel-generator sets not running, which increases the efficiency. At large scales, conversion efficiency is pretty good as well, comparable to gearbox losses. Also, the azipod propellors are perfectly aligned to the direction of travel, where shaft driven propellors are quite often at an angle.

[@johnburns4017]

Paul Langford​​​​​ Also Azimuth propellers have full flow across them. There is no Hull in the way of the water flow path. This is adds efficiency. Having a number of generator engines means they can be banked and sequenced in or out to demand. Again adding efficiency.  Wankel engines are efficient running at a constant speed and one third of the power and weight of a diesel. They are also very smooth. Upsize a Wankel (they scale up no problem) having them as gensets and they can replace dirty diesels in cruise ships where smoothness and space saving is highly desirable. Rotaries run on LPG very nicely. Many cruise ships are turning over to LPG. Stirlings are very efficient but large and heavy. This is where Wankles score well in ship applications. Small in physical size banked Wankles as gensets can be swapped out, complete with genny, and in a matter of hours on a scheduled maintenance on a port stop, to be reconned ashore, eliminating large engine overhauls in dock which takes up revenue earning time.  The rotary gensets can all be in a frame and each one fixed to skids to slide in and out. One out and a recon set in, within a few hours. 

[@paullangford8179]

+John Burns Unfortunately, no Wankel motor comes anywhere near the efficiency of diesel. The big turbocharged two-strokes on ships quite often get better than 50 % thermodynamic efficiency, running on fuel like oily custard. No Wankel gets anywhere near this, apart from theoretical, "works by magic and wishful thinking" versions that don't actually exist.

[@bowserkidgamingAmaya]

how many ships look the same?

[@RoskapussiOfficial]

bowserkidgaming Amaya If by looking the same you mean built to same class, 3: Oasis, Allure and Harmony. More to come.

[@ducke295]

And how many liters is one of those engines

[@jasperpaguio2320]

cruise ships can now do translantic voyage? I thought they are not designed for high seas travel.

[@LeftyStratPlayer]

+Jasper Paguio Cruise ships have always been capable of transoceanic voyages. But due to them being wider and boxier than dedicated ocean liners, they're not as streamlined, and therefore not as efficient as cutting through the water at higher speeds.

[@AlexRyteuBart]

@Noctis411 Nuc is expensive and takes more space than big diesel! They dock every few days so they dont need long range ability ;)

[@salemcripple]

CSX is a Rail Road and shipping company here in the US. You can probably find the commercial i'm referring too here on youtube if you look for it. And yeah, i know what you were talking about lol, just thought i would chime in. You know i read somewhere that the QM2 gets something like 6 inches to the gallon?

[@stevevater8598]

The comparison to mpg is misleading the QM2 weighs 98000 ton + a car weighs 1.5 tons ,that's 65333 cars. Average fuel consumption in real work 42mpg.if you then devise the no of car available mpg and see how far the travel per gallon its 0.377 ft which means the QM 2 is does more . !!

[@WamsWarrior]

when you see the view of zini allure looks like shes going reeeaaalllyyy slow.... I wonder how much the fuel tanks can hold because for a transatlantic crossing the engines run for days and i think they would run out of fuel...

[@newda898]

That looks like Naocs platinum there does that it does.

[@salemcripple]

Actually, big ships are very fuel efficient. Pound for pound, they're far more efficient than much smaller boats. Look up the economics of scale. It says that the more weight you can carry with one boat (or train), the more efficient per pound it is. This is why you see CSX commercials that state they can move one ton of freight 100 miles on one gallon (because it's big and powerful enough to do so).

[@dash0173]

Soooo if you could fit them all in the ship, you could either have those 6 engines OR 810,000 horses lol...

[@Finstatube69]

this 2nd guy MUST BE NORWEGIAN

[@ecoRfan]

2:11 Solar panels on the roof? Why aren't they explained in this video? They would feed into the ship's power grid. This is as state of the art as it gets in shipping.

[@Gamebreaker08]

What a young captain, I bet his wife is HOT!!!!

[@Gamebreaker08]

+Andrew Armstrong shit man, even better! At least for me. Lol jk

[@musicnerd72]

Gamebreaker08 I wouldn't mind taking a tour of the captain! 😀

[@joewood1335]

someones never been on a cruise seeps like you need one damn

[@SuperChamps29]

what language he is speaking?

[@91cat]

Is this from sweden? He sounds a little bit swede

[@FrankandSandyShow]

Truly amazing power! Sandy and I did a 1080p HD Video of Allure of the Seas and (in another video) a comparison with Oasis of the Seas. You can see the ship in its full glory in full high definition quality. Just click on our username and look for the video with "1080p HD Amazing Allure of the Seas".. Take care! Frank and Sandy (from the Frank and Sandy Show).

[@partyman6666]

If you put an aftermarket muffler on that ship, you could have 135,011 HP..... maybe more if the motors have V-Tec.

[@mulgeroinen]

@dodgingdaniel yes it is

[@athriaxo]

I dont even know what a CSX is (since im from Europe) but of course you are right but still the mpg is gonna be horrible... the gallons per ton might be realy great but the mpg is still gonna be terrible so what I said isnt wrong :P

[@29223gilbert]

look at those bags under his eyes, looks like he got beat up... jajaja my uncle is a captian for a ship a ship, i dont remember where, but he can work up to 14-16 hours a day... pretty hectic for a captian

[@spaceye]

97 megawatts! And for just one ship...

[@nanicoar]

HUST UP AND SOUND THE HORN

[@gangiization]

cruiseship equals a slaveliner BEWARE WORKING ON ONE

[@bektop1982]

@Olaf16 This engine is 10 times bigger than your car. :)

[@Voodoo_One]

Can I has one engine for my Car? ;D

[@gigiting2559]

your car will be like a brick in the working washer.

[@morduearachello]

wont go very fast unless you get gears opposite to reduction gears

[@Voodoo_One]

@Hubieee It's actually "haz" as I think... But well, who cares? Its from a Cat that said "Can I haz cheezburger?" (Maybe you know those cat pictures with the phrases in wrong way written)

[@Philip02K]

It takes 20 years out of mariitime academy to be a captain

[@PetaLucien]

And I thought my Civic had enough horsepower.

[@wasi_ahmed999]

Propellers

[@athriaxo]

You know something is wrong when your mpg is only possible to calculate with a octacore computer ... xD

[@Timppapoika]

Is that really a Norwegian accent? Sounds like a mix of Finnish and Swedish accents.

[@Voodoo_One]

@bektop1982 Who cares... Power to weight Ratio :D

[@MegaTubetraveller]

Diesel-electric drive has lower efficiency but more convenient

[@Voodoo_One]

u must be new to the internetz :P well, i made a mistake. Its actually "I can haz engine for my car?" :D

[@athriaxo]

Hahaha 6 inches? Imagine they run out of fuel and need to make due with like 20 gallons... that ship would move at the speed of a tectonic plate hahaha

[@ireneskippett]

The engineer mentioned very 'redundent' systems, his English wasn't perfect, I think he meant 'reliable' systems.

[@carmelpule6954]

He did mean redundant systems. The benefits of having diesel electric propulsion is that one can have many smaller engines powering electric alternators which are all fed to the switchboard, this will not only provide reliability but what one calls redundant systems as if a few engines stop there will be enough left sail the ship to port. Most aircraft and sea vessels have redundant system designed in them these days.

[@lgmmrm]

he's got it wrong anyways, it's not, "Can I has" it's "I can haz one engine for my car?"

[@111TTV]

i always have wanted to be a cruise ship captain and if someone banned them than my life would suck anyway sating you want to ban ships is like saying you want to ban all forms of transportation on earth that involve gas. the only cruise line i say that should be banned is carnival cruise lines i hate them

[@D.Garcia007]

Wtf are they saying? Can't understand

[@Hubieee]

@Olaf16 is this a kind of new youth speech, to say "has", thats 1337, isnt it?... it suxx0rz

[@ph11p3540]

I'd much rather sale on the Queen Marry 2. Safest ship to be a passenger on. It's not that the ship can sail with little effort through the worst storms but it has the best hand picked crew in the industry. Sorry man but the Allure is just a cruise ship. It's not an ocean liner.

[@seanwilson5820]

The Queen Mary is a tug boat compared to the Oasis Class ships.

[@brandonnava6338]

Phillip Mulligan I wonder the kind of mpg that thing gets?

[@fudge132]

Phillip mulligan What.

[@crazyfroggie6546]

It's not MPG when you are talking about something that big. Think more GPM, gallons per mile

[@scottwhitley3392]

Sean Wilson the queen mary is a full ocean going vessel and can sail through hurricanes, the allure is floating hotel that has to travel very slowly and carefully across thw Atlantic

[@blulaguna18]

sexy captain

OHh wow... U are not very familiar with internet (memes)? ;)

[@obscureluzername]

I don't understand...are you saying that you are gay?
