The Engines of the Titanic 

I can tell you that this man enjoys showing a product that others are also interested in.

​@@Hoeishetmogelijkgreatness - helping me recover from surgery. Many thanks

Yes, that was really very clever!

Not that it got them far

Did they not have sliderules for calculations? Did they not have "computers" of the two-legged variety?

The technology was not that new then, they had had steam engines for over 100 years, so they knew what they were working with.

The turbine is what I found great. The machining and fluid dynamics involved in the turbine is amazing for the time. It's very similar to a modern day jet engine. The stationary blades directing airflow into the moving blades is brutally simple but getting your head around it back then and making it was anything but. "Theoretically" they were mostly into the jet age with the turbine alone.

good film on that subject: Saving the Titanic. An Irish German production. 2015. On Prime

Exactly 💯 💯, so sad and terrible that beautiful brand new ship was only 3 days old after being built for 3 years and then sinks and everything is underwater to waist away😔

brand new might be a strech now, but yes.

Shit happens y’know?

@@Boxscot49 haha

It would have been a brutal collision, but would have been better if she hit the iceberg head on. Maybe she splits the berg in half. Who knows.

@@rbarger71 maybe they should try it again

@@rbarger71 Don't think she would have split the berg but it has been proven that she would have been much better off to hit it head on. The first and maybe the second compartment would have flooded but not enough to sink her.

Inside a hull riveted by hand. Different times..

@@pelnapkins4379 and it was hot hot hot! Hot environment + physically demanding labour = HOT.

ThatGuy Ollie And didn't complain while doing it. No excuse, just produce.

Not entirely, the builders of Titanic used hydraulic riveters and steel rivets on MOST of the hull, but in areas that were very curved, they had to install the rivets by hand, and that forced them to use wrought iron rivets instead of steel rivets.

Not that hard, I have shoveled over a ton of sand in less than an hour, several times. At 63 yrs old, just part of the job.

I agree with You. Respect and the safety of the workers has progressed a lot since then. Regards.

They were well paid and well respected. Until Oil fired boilers came around, a stoker strike meant ships won't sail. And operating on tight schedules and slim profit margins (the ship had to pay for it's construction and operation. Took 10-20 years for it to turn a profit), stokers could stop the world if they wanted. But it was a hard, short life. Breathing coal dust caused silicosis and being an industrial setting you were subjected to stuff falling from height occasionaly. A cloth mask and a helmet would eliminate these hazards completely. But we simply didn't know any better. And it probably was HOT. Being under the waterline though, maybe it was not as hot as we might think. They had plenty of ventilation by air bled through the furnace air intakes.

Yes i think you have summed that up very well, they would have worked their asses off, heat well you surrounded by boilers it is going to be HOT!! Similarly the fire men on steam loco,s summers day 25--30 deg C outside, 50++ inside the cab, driver wants MORE steam Big hill coming up, better get shoveling!

life is all about choices

My dad was a stoker in 1930s and spent 50 years at sea, even in his 70s he was someone you wouldn’t mess with, those men were a different breed

+Raptor05121 That's why I am happy with it!!

Amen Brother.

Raptor05121 my best guess is that trolls would have a hard time stumbling across this lol

Well screw you too!

No shit, Sherlock

And other scenes were shot at Kempton Park and the whole thing stitched together digitally.

Fun fact the Liberty ship series was cylinders engineered , not steam turbine

@@patsematary That is correct. Warships had priority on steam turbines, so the Liberty ship used obsolete expansion steam engines. But they were easy to build and very reliable.

The Jeremiah O'Brien steamed from San Francisco to Europe and back to celebrate the 50th anniversary of D-Day. There and back under her own power using the original equipment. And this after sitting in mothballs in Suisun Bay for over 30 years. Well built, well maintained. I wonder how long the Titanic could have lasted?

Why didn't the Titanic have mechanical stokers?

Very interesting story. Many thanks for that.

Would the stopped centre propeller have freewheeled in the flow, turning the turbine with it?

MechaGaming not just you. They are satisfying. They sound like music to me. Large engines are some of the best music devices to me.

Like the beat of a mother's heart, heard from the womb.

No its not just you, they are almost like big animals in a way, as if they had a heartbeat and muscles! Sounds silly and maybe its just a male thing?

Reciprocating piston steam engines built for ships are the absolute best. Diesels, turbines,nuclear,electric are fine, but boring compared to marine steam piston engines. Kronprinzessin cecilie ship was said to actually have the largest built.

No it's not just you. Live steam speaks to me, reminding me of a by gone time. A time when men were real men and worked with their hands.

@@MrSvenovitch do you have absolutely no respect??

@@clf8965 Lol what? Where was he disrespectful? All he did is say the truth 😂

Mr. Andrews was primarily responsible for designing the topside fittings - he was a high-ranking and important designer for Harland & Wolff, but he was not the person who designed the engines.

There's enough quality now. But normal people can't afford it. Just like back then

@@nstl440 That's true for many objects, there is still quality now but it is expensive, but I was thinking about how many things could be built with the purpose of not only being practical, but also beautiful. For example a street lamppost, there's a big difference between a decorated metallic one and a plastic one, yet they both work. The same goes for the houses. And what about modern luxury cars? The infotainment systems are very helpful, but in less than 15 years they will be outdated. The train could be one of most glamour means of transportation, but today they have bad interiors, and depending on the country they might be dirty and inefficient. We are losing that "WOW factor" past people wrote about, when they saw a huge ocean liner, a Zeppelin or a passenger plane going twice the sound of speed. And it is so hard to find everyday objects made from durable and ecological materials, even if you're not looking for luxury. Mine was not a rant about the nostalgia for a time I've never experienced, but a desire for a more humanistic world: not one built around the economy and the corporations, but around nature and our needs as humans, our duty as part of this planet, as we are animals and not machines.

@krvnjrcbs What do you mean? The Titanic was an engineering marvel, the best ship of the time. The incident had nothing to do with how the ship was built.

@krvnjrcbs Oh, you're one of "those" guys. I would like to remember you that the Titanic was insured for just a fraction of her value. There are many arguments disproving the "insurance fraud" theory, I suggest you look them up.

@@litamtondy calling someone one "those" people is very condescending of you. Get off your high horse and hear people's beliefs out for a change. Its not uncommon to want to doubt written events especially in a world where history is written by a dishonest few. You sir are a tarnish in human debate

Laquinton Wagner never said it had anything to do with that. I just said it’s sad we lost marvels of engineering.

fuck yeah yer right! To me they are the most beautiful ships ever made. You seen the vid on the tube where they blow the Titanic's horns? And you seen the video on youtube "the Olympic arrives in new York 1934"?? check thses out!ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6r0u5hhcU0U.html

I'd argue Lusitania's propulsion plant was more ahead of her time, largely thanks to turbines instead of triple expansion steam engines. The turbines Lusitania used were precisely what the Navy of WWI used for its capital ships. Now if you're talking about furnishings and luxuries, Titanic put them all to shame.

Not to mention survived multiple collisions and rammed a German U-boat! I absolutely adore the Olympic

I suspect the 9 psi quoted as input pressure to the turbine is in fact gauge pressure, not absolute pressure. So that would be 9 psi *above* atmospheric pressure. :) Otherwise I struggle too to understand how one could maintain steam flow towards the turbine with a partial vacuum at the input when its outlet, at least on start up, would be at atmospheric pressure!

Ah, but the outlet from the turbine, and engines themselves when bypassing said turbine, isn’t to the atmosphere. The steam is routed to a set of large condensers that turns the steam back in to fresh water to be returned to the boilers. Keeping the whole boiler feed system a mostly closed loop instead of an open system. These condensers used seawater as coolant, and especially in the North Atlantic where it’s quite cold they were quite effective at drawing down a vacuum in the steam system.

+heffo and juff one point only it were not triples, but quadruples ..(temds???).for as far as y know

+MrBugsier5 You know what, I think you are correct. I know the engines ran on super heated steam.

+heffo and juff I keep telling those pesky boiler operators the same thing my gramma told me: ''Don't you know that a watched pot doesn't boil?'' How can you tell a well seasoned steam operating engineer? His boots hit the desk before his ass hits the chair. Ain't it nice being retired?

+heffo and juff A gentleman I knew many years ago (he had to be in his 70's or older when he worked for my father) was a master toolmaker, who had 2 hobbies; history and building (working) model steam engines. Pretty much anything he did was a work of art, but his steam engines were amazing. I'm also a fan of steam locomotives, and right now I'm closely following Union Pacific's rebuilding of Big Boy 4014. If you've never seen a Big Boy it is hard to comprehend just how huge a locomotive it is - weighing around 250k pounds; I look forward to seeing it in operation in a couple years, first time in nearly 60 years that one will operate. Of course, I really like steam ships; my favorite is the SS United States, which if finally brought back to life soon will certainly lose its aircraft carrier based steam. This ship could do somewhere approaching 40 or so knots without all boilers lit off.

+Ron Troy The Old Town Railroad Museum in Sacramento, Ca has a HUGE Forward Cab Baldwin, No. 4294 that was operated by Southern Pacific. I have never seen a Big Boy close up but this Baldwin 4-8-8-2 is absolutely massive. I hope the SS United States will be saved by its new sponsor. The interior was gutted to remove asbestos. I worked for GE Marine Department and had some pretty big steam turbines and gearboxes apart on carriers, container ships, oil tankers, and subs and still have an interest in such propulsion. Every October I ride the SS Jeremiah O'Brien still operating liberty ship in San Francisco Bay. Its on RU-vid for those interested in watching the engine in operation.

Lol. Right? It's soothing in some manner. If I wanted to I'd put on headphones and go to sleep to the sound of a steam engine or large diesel engine. Large engines make for some good music.

Boonk dookah shhhn (dookah)

Cash-to-the-mere Cash-to-the-mere lol my comment was 2 years ago

That is true music to us

I was bobbing my head to this all time. nice music, yes

Oh some of that “music” they put over videos is horrid. I usually end up muting it.

That repeated sound got annoying fast.

Juna True, it should have been at least a minute or two sample rather than a small snippet that was repeated indefinitely.

The ancient Greeks were capable of making mechanical computers.

Using an army of 15,000 of skilled workers from all over Europe and beyond, but most of them were among my Irish ancestors. They worked night and day for nearly four years to build all three Olympic class ships.

Please subscribe to my channel.

1912 was just seven years from the first non-stop Atlantic flight, the end of the liner era was almost imaginable.

@@piotrmalewski8178 greeks who?

Flying cars didn't arrive until 2045 as preference was given to the development of a clock work engine. With the spring being wound up by an exactly matched key. The exact matching of this key to each engine was to prevent unauthorised starting and theft. Once available power/weight ratios were sorted out the flying car was placed into production. One wind of the spring would give you enough energy to fly the car 100Kms. It could also be wound up whilst in flight giving it great versatility. And best of all no carbon foot print.

@@Becu1001a _come again?_

+Matt Schuette Not to start it but to warm it evenly and eventually blow the condensed water out of the cylinders. Steam engines are self starting.

+jibemorel oh and for lubrification purposes to.

+Matt Schuette I'm not sure that's actually a steam engine, it looks (and sounds) like it might be a petrol powered one. Lighter and more compact for moving by hand against the huge flywheel, for the same power, and no need to deal with setting up flexible pipes etc for it. Be quite easy to turn over and get going by hand, especially in a warm environment like that, and a heck of a lot safer to be around. Open crank etc because a lot of cars were still made like that, and when it's only going to run for mere minutes on a typical voyage, you can just hand-oil it. And it only needs a very small fuel tank as well. Not the greatest amount of torque of course, but that's been demonstrably compensated for by ultra-low gearing... which turns a lot of power at high speed into a lot of torque at low speed. Just a pity no-one had quite managed to crack making a really big one of the type a ship like the Titanic needed. Nowadays of course they're all diesels and need a team of maybe 5 or 10 guys to look after them at most despite developing a hell of a lot more power...

mspenrice Nah, its a steam engine, I seen a video of a replica of the Titanic's engines. It is a small steam engine that gets the larger ones moving. I'll find it and post it here

+Matt Schuette Fair enough then. Suppose when you have that much live steam knocking around you may as well use it. Just seen little auxiliary petrol engines used for getting other large machines moving before.

Just some more turbines, driven directly on steam I guess. A lot of space, maybe towards the front.

@@123Chevyman I already know the location of the electric engine room. It was was just aft of the turbine engine room, and contained four dynamos which I think were piston style engines, but not 100% on that. What I meant by "how they fit into the plan" is that I'd like to know how they fit into the steam pipe network specifically, and also the interior workings of how the engines themselves functioned

No they werent towards the front. That was the reason why the Titanic did have electricity up until the very end The Dynamos were dry in because the aft flooded last

@@Rudeljaeger yeah, the electric engine room was far aft on tank top level, just aft of the turbine engine. And then also there were the back up dynamos about 2/3 or so aft on D-deck, around about where the ship split. It's not likely that either saw much flooding before the break up, and the break up probably crushed both rooms anyway, so flooding was the least of their worries at that point

Yes but slower and sometimes they failed

I think the best ones honestly.

they are so calming. a good earworm for someone who has bad anxieties.

Yes, and all was brand new!

why don't they salvage the Titanic? They could restore it and make it a museum. I'd love to visit it.

Chris Keller also it's basically one big grave

But hey they built the Titanic II but I'm not sure if it has the steam engines like the Titanic had

Imagine if the Olympic’s engines hadn’t been scrapped. They would have been the largest triple expansion steam engines ever existed. Larger than the Kempton engine.

16,000 hp per pair? or EACH? if the later, holy crap....

46,000hp for the titanic, a few thousand hp more for britannic.

Note that, in 1911, Olympic's chief engineer stated her engines had developed 59,000 horsepower at maximum revolutions. Britannic would be capable of even more. A 1940s report of H&W's tonnage completed in 1914 put it at 60,000 horsepower.

I suspect they need to qualify their statement and refer to both triple expansion (as opposed to quadruple expansion) reciprocating engines and for marine, rather than on shore, use. In the case of either Olympic or Britannic's reciprocating engines, they could work well over 80 rpm and develop more power than quoted here. Your mention of rolling mill engines reminded me of a quote. "I do not think many people who have not been there, realise the enormous power that there is got from the steam pressure in these engines; they move comparatively slowly even when at full power, and the power behind them is, I think I am correct in stating, larger than the power behind the biggest rolling mills in the world. That is, the biggest mills that are used anywhere for the rolling of steel plates, as distinct from the forging of armour plates," - Harland & Wolff ’s Edward Wilding, spring 1912. I don't know of any specific examples or whether they used quadruple expansion engines in rolling mills for steel plating?

That is 16,000 shaft horsepower each.

Agreed - a great explanation.

Sir im confusing what is the meaning of CAD?

@@robinfernandez1992 Computer Aided Design.

Thankyou for that sir .

And when they worked, they worked. No distractions from phone calls or emails or zoom meetings.

Two thing: , a team of well dressed engineers. and No RU-vid !

different boiler setup on the Kitty Hawk because Titanic was coal and Kitty Hawk was diesel fired boilers. Either way I wish I had the experience you did. I never made into the fire room on USS Guam to see the engineering plant.

Actually, that's a "barring engine". For smaller engines, to put the engine in starting position (high pressure piston just past Top Dead Center) an engineer would have used a crowbar to adjust it. Also, before the engine was started, it was necessary to make sure no water had condensed in the cylinders, which would severely damage the engine. So, the engineer would "bar it over" one full revolution. When engines became too large for this, the barring engine was added.

Mark Stockman that's awesome thank you for the extra information, hydraulicing is never a good thing and I didn't think about that being an issue but it makes complete sense! I have a Cat conrod that is bent into an S shape because an injector leaked causing the cylinder to flood.

Mark Stockman also known as a pony engine.

Only non-reversable engines had a small ("barring") engine, it was to bring the pistons to the correct positon for starting. Reversable engines did not need it, they could start in any position.

There are 2 stroke not 4 joke stroke crap!

I agree about the spelling. It was an excellent video but I was distracted by all the spelling errors throughout. I understand spelling is not everyone’s strength but that’s the reason we have spellcheck. Lol Loved the audio, however, as it was very calming to me.

Not me. Jack and Rose are just an invention to sell movie tickets. The fascination of Titanic has always been in the real people who built, sailed and died.

Thanks!

Which ships use Gas Turbines? There is not a single civilian vessel that uses a Gas Turbine engine that I can think of. The only ships I know of using Gas Turbines are Destroyers and Cruisers of the various Navies around the world. Please do research before posting a comment that you are trying to project as fact.

@Brian Barratt it actually was quite complex for it's time. Also most ships nowadays use medium speed 4 stroke and low speed 2 stroke diesels. Gas turbines are used to power most destroyers and some cruisers. Capital ships like supercarriers use steam turbines driven by a nuclear reactor.

@Brian Barratt true. But it's impressive how they made ships like that without the help of computers or even simple calculators. Just raw brainpower and work.

@Brian Barratt yes indeed. Making such a machine without the help of computers is amazing. It's just a shame that such a beautiful ship is now at the bottom of the ocean.

They sank.

+davida1hiwaaynet Also if "decision making technology" had realised the limitions of the navigation technology of the day, this tragedy could have been avoided.

I think pride was a big factor. If they had not sailed with blind faith though an ice field the story might have been different too

+davida1hiwaaynet if they hadn't reversed the engines when the iceberg was spotted she would have made it. You cant steer a ship of that size with little propulsion going past the rudder.

+Zachary Lagler The reversing encouraged the ship to broadside the iceberg. Should have only steered.

Zachary Lagler Yes, very true. Reversing the centre propeller made the already-too-small rudder ineffective. Amazing (with the luxury of hindsight) that this design was operational.

The steam is condensed to water. I don't know how much water is produced to return to the boilers. Perhaps someone else who knows?

216kg of steam per minute from the water inside Boilers. See Encyclopedia Titanica.

Are you an engineer?

@@LanaaAmor Yes, and analyze steam system but use modern SI units.

Yes, it is complex.

The First ones were but this one

A very clear analysis. Thanks!

I'm curious how efficient steam engines were back then. How much of the energy was wasted out the exhaust stack? An internal combustion engine only uses about 20% of it's fuels energy, the rest is wasted as heat going out the tail pipe or radiator.

@@johneckert1365 It all to do with the temperature and pressures involved. A boiler has a limited pressure and temperature it can withstand. Internal combustion can reach much high pressures and temperatures but of course it is a cyclic process whereas a steam turbine is a continuous cycle. The higher temperature and pressure of internal combustion may give it a better heat efficiency than a steam plant but the products of its combustion are more toxic to the planet.

+Ignignokt Mooninite Yes, I agree with that

I always think of that. All that iron, all the carved Mahogany, crystal, stained glass, and bronze. Jewels and fine clothing, artwork. All at the bottom of the ocean.

Imagine how the builders of the Death Star felt.

+Brian Merritt um they and he is dead in you watched rogue One

bruh

They didn’t even hit it head on, even if they did the ship would’ve probably had a higher chance of survival

Titanic was running at nearly full steam the moment the iceberg was spotted meaning it gave them even less time to react and avoid the burg. Not to mention the rudder on the ship was too small for it's size making it slow to turn. There were so many variables at play and unfortunately it all went to shit for them.
