A Complete Guide to Titanic's Engines

[@OceanlinerDesigns]

This video is a remake of a video from about a month ago where we explored how Titanic’s engines worked. Some annoying issues and missed points have been eating me up though so I decided to see out the year by revisiting the subject and overhauling the video with new additions and information. Enjoy and happy new year!

Maudlin comments about the Titanic aside, it’s even cooler to think about how these same engines on board the Olympic were used in a combat scenario. The engines empowered Olympic to quickly overtake, ram, and sink a German sub (U-103) during WWI, accomplishing this feat not by firing weapons, but simply using the raw strength and engineering capabilities of the engines themselves. Olympic is still the only ocean liner in history to ever accomplish such a move. I wish your videos highlighted the amazing history of Titanic’s unsung sister ship more!

[@mikeynth7919]

Had a regiment of US infantry aboard, who later sent a bronze plaque to Olympic commemorating her feat. I think that plaque still exists today, though I don't know where. It read: “This tablet presented by the 59th Regiment United States Infantry commemorates the sinking of the German submarine U-103 by the Olympic on May 12th, 1918 in latitude 49 degrees 16 minutes north longitude 4 degrees 51 minutes west on the voyage from New York to Southampton with American troops."

[@DistractedGlobeGuy]

Also as much a testament to Captain Bertram Hayes and his skill as a mariner. Every sailor in every military division of the whole British Empire was taught to attempt that procedure when facing a U-boat, but IKS SM-U103 was the only one that didn't manage to escape.

[@PromusKaa]

@@DistractedGlobeGuy Indeed!! In fact, in his autobiography, Sir Hayes says they actually sunk TWO submarines; according to him, the submarine they hit got basically sliced in two, with both halves going vertical before sinking. He says the U-103 is the one that was spotted behind them, which they opened fire on and damaged enough that it eventually sank, although a portion of that crew survived (including the U-boat commander). Honestly it makes a bit more sense to me! The events with a single u-boat never were very clear, in terms of HOW it was hit. Hayes acknowledges that most say he only sank one, but he also basically said he already got a pretty big honor out of it and wasn't going to press the issue, lol!

I am heavily involved with vintage steam machinery, engines etc at the Melbourne Steam Club here in Melbourne Australia, we have two triple expansion ship engines at the museum, both are operational with an output 0f 600hp each, small compared to Titanic but the operation of them gives you an idea of the sound that would have been normal in Titanic's engine room. There are hundreds of checks and ongoing checks to keep these engines operating reliably including lubrication, and using your ears which for the operators was a paramount skill as any change in sound meant an issue. This was a great video, and the CGI was very good giving us a feel for the interior of one of my favourite ships.

Right! The level of sophistication of shipbuilding of the time is downright astonishing. Especially when you consider 50 years before Titanic the overwhelming majority of oceangoing vessels were still wood-built and sail powered. Columbus could have captained a ship from 1860 but not one from 1910, he'd have been overwhelmed.

[@wayneantoniazzi2706]

@@EnjoySackLunch Think about it. A ship from 1860: Wood, canvas, sails, wind-propelled. The configuration would have been different from a 15th Century caravel but the principles would be the same. A ship from 1910: Steel, steam, electricity, size. Aside from the principles of navigation which wouldn't be too much different the ship handling and propulsion and internal systems would have been alien to Columbus. Not that he couldn't learn of course, but I'm speaking of theoretically dropping him on the bridge cold. Get it?

[@thedubwhisperer2157]

Shifting that weight is not as dramatic as it sounds, but would have been in such awful conditions. At 14 years old I regularly loaded/moved 8 tons of straw bales in a day, and at 62 I can still easily load 1/2 ton of coal from my van to the bunker in 25 minutes. I am quite large but remain far from exceptional amongst the people I have known!

[@SynchroScore]

The casting is pretty impressive, but at the end of the day you're still just heating up a bunch of metal and making it into one big lump. I'm really impressed by the machining of it, cutting such massive parts to the precision needed for efficient and reliable operation. Even today that would be difficult, and we have the advantage of advanced materials for cutting tools, digital readouts for machine tool positioning, electric or hydraulic servo drives, and eventually CNC control. As a machinist, I find it fascinating that something so large and powerful could be machined, at a time when high-speed steel was still mostly a laboratory project rather than a commercial product.

[@haweater1555]

​@@thedubwhisperer2157We don't use bale thrower wagons, just stack it behind the baler on flat wagon. About 150 bales a load, assume each is 40 lbs gives 6000 lbs or 3 tons a load. Takes about 45 minutes minutes per load so you're moving 4 tons an hour. Keep that up for several hours a day. So Tennessee Ernie Ford's "you load 16 tons, another day older" is entirely realistic. Except shoveling deep in a coal mine is a far worse job than farming.

[@carmadme]

Yeh 3 tons of coal isn't much at all really although the conditions would've made it much harder Conditions had much improved for the boiler men by 1912 Personally when I was a labourer I would easily mix 15-20 tons of sharp or ballast into screed or concrete in a day It was a busy day and had to work quickly so we didn't over run but I wouldn't say it was particularly daunting

Very nice Mike. Quite detailed and updated. I'm blown away by the technical advances of the 20th Century.

Wow, she really was a technological advancement and at such awesome fuel savings. The 20th century really was an technological leap forward in so many ways.

[@tz8785]

If the condenser temperature is low enough and the steam system is closed to the environment, you can expand steam below ambient pressure.

[@thepoet9253]

​@@NaNlinear Mike actually addressed this in the other video. It's 9 PSI Absolute, as referenced by Harland & Wolfe records and writings.

[@markkinsler4333]

That was an old principle in 1912. It was developed by James Watt around 1800.

[@holysirsalad]

Running in the North Atlantic would've helped in this regard, as pulling such frigid water through the condensers would have increased vacuum on the steam side. It's a bit funny that taking in colder water and deliberately dumping heat (the main product of a coal fire) into the ocean actually improved system efficiency, but the engines work on a pressure difference, rather than temperature. To illustrate this, consider that at sea-level atmospheric pressure, water changes to steam, and vice-versa, at 212°F. At higher altitudes, like in the Swiss Alps, water can boil at only 195°F. Titanic's boilers were producing 215 PSI steam at around 400°F. By the time it left the reciprocating triple-expansion engines, the steam was down to 188°F - but because the pressure was so low, it was still steam! After leaving the turbine, it was colder than a cup of tea at around 100°F... but STILL a gas! It wasn't until the condensers dropped the steam to 60°F that it finally returned to water. It was good engineering but not a new concept at the time. The Industrial Revolution started about a century and a half prior, but these concepts go back to the late 1600s and early 1700s: A lot of work is credited to Denis Papin, who, also known for essentially inventing the autoclave, pressure cooker, described a piston steam engine working on these principles in 1690.

I'm just lost for words, the sheer scale of engineering! Thank you so much for sharing this amazing ships triumph and tragedy.

[@stephennx2103]

Well done, Mike, once again. Anything Titanic seems to be endlessly fascinating and you present these documentaries really well.

[@MrRajsta]

One could now understand why so many water tight doors were needed. The engineering involved for efficiency is really impressive.

[@henryreimer4822]

Fascinating description of the engineering of the Titanic. I have always wondered how fascinating it would be if the Titanic were to be rebuilt as it was. I know it would be an extremely expensive endeavour but fascinating to see. Cheers Mike on another awesome video.👍 absolutely incredible

[@EnjoySackLunch]

Thank you for making this Complete Guide to Titanic’s Engines. I watched it on TV tonight but wanted to comment so I brought it up on my IPad so I can tell you that it’s wonderful! I wish my father was still with us to see this (He would have been 100 years old as of today.). He was a pattern maker for metal castings and would have appreciated the wooden patterns for the outside casing of the huge turbine engine. You are so very good at explaining these ships.

[@American_Savage]

You could make a 36 minute long video about Titanic’s toilets and I’d watch it.

[@tiggerforhim]

Honestly, same. The whole ship is such a technological wonder that every part (toilets included) is fun to learn about, especially from Mike Brady!

[@EnjoySackLunch]

Creepy

[@microndep]

Nor me either. Tozzpot seems intent to prove me wrong no matter what I say. So, I'm dropping this entire conversation.

[@microndep]

My original post was about how easy it would've been to avoid the collision. But the entire post seems to have morphed in toilets from my point that the ship struck the berg on the side it was easiest to avoid it.

[@DistractedGlobeGuy]

Matt deWinkleer has one on his channel if you're that keen on it, although his is only about ten minutes.

[@sovereign254]

Honestly, the engineering genius of Titanic's designers can't be overstated. The genius of how the largest passenger ships afloat at the time could move at near-Cunard speed while burning 40% less coal boggles the mind, that nearly every joule of energy was sucked out of the steam in order to power the ship through the ocean. My interest in Titanic started with how opulent it was and of the hubris of man, but lately I've found the engineering and design of Titanic to be equally as fascinating. The ship stands as a marvel of Victorian/Edwardian engineering, that just about any way man could divine and design a moving system was implemented in some way, shape, or form in one single ship. While there were definitely engineering oversights made, like how the watertight bulkheads ought to have been built higher or there not being ample lifeboat room to evacuate the entire ship, it doesn't take away with the genius it took to create the largest moving object made by the hand of man at the time.

[@admiralcraddock464]

Not just the genius of the designers but also the skill of the craftsmen. Imagine fabricating the patterns for the molds, the skill of the foundry men in pouring the molten steel into them at the right temperature and speed to ensure it flows into very part of mold without leaving any weakening voids. The experince of the machinists in machining the faces of the castings to fine tolerances and then the other tradesman in marking, and drilling hundreds of hole so everything would assemble together. In any one of those steps one mistake would have cost thousands of pounds and put back delivery of the parts, possibly. by weeks

[@msz5543]

Mike: Would you consider doing a video on survivability in general, along with specific regards to Charles Lightoller? By all accounts anyone who had to be fished out of the drink, or clung to a boat that night should have been gone long before Carpathia arrived. Twenty eight degree water, an air temperature in the low 30's, yet after being sucked under water and nearly drowned, he makes it to an overturned collapsible, takes command, hours later hooks up with another boat, transfers all to that, and is the last person to board Carpathia. How could he do this? Even Bride lived with, I believe, severe cold injuries to his foot. Obviously getting out of the water was the only hope, but still, these people were soaked. How did they not all succumb to hypothermia? I think a look at Lights and others who defied the odds would be pretty interesting. Regards.

[@wayneantoniazzi2706]

How did Lightoller manage all that? I'll tell you, adrenaline and command responsibility. Both can keep you going longer than you might think. Trust me, I know from personal experience. (But not like Lightollers!) Lightoller stayed alive, functioning, and providing leadership because somebody had to and that somebody was HIM. Sometimes that's all there is to it.

[@msz5543]

@wayneantoniazzi2706 It is amazing. He reportedly boarded Carpathia around 8:30 in the morning, meaning he was wet for 6 hours. Others were wet, too, and lived, but some died in the lifeboats. He was part of the "small boats" that crossed the Channel to rescue the B.E.F. at Dunkirk. Quite a guy. I sent this idea in over a year ago, and our friend Mike Brady replied that he was interested. Now, just crickets. Oh well, LOL

[@wayneantoniazzi2706]

@@msz5543 Mike might still be interested (Although obviously I can't speak for him!) but I'd guess the problem for him would be finding the source materials and photographs and putting it together in an interesting manner. Can't be easy. One thing I should have mentioned about Lightoller (but forgot to) was as soon as it was "Abandon ship! Every man for himself!" Lights could have done just that, looked out for himself and himself alone, but he didn't. Even drenched in freezing cold water and narrowly escaping with his life he still took command and brought order out of the chaos of the overturned collapsable boat. Quite a man.

[@msz5543]

@wayneantoniazzi2706 Mike puts out fantastic material. I watch and rewatch it all the time.

[@markbeale7390]

You'd sink in the water from escaping air as ship sinking,not sucked under.

[@TheHylianBatman]

This time around, I'm thinking of Olympic's engines. When she was scrapped, it was stated that her engines were as fine as ever. I wonder if her scrappers had the sense to remove them and put them somewhere they could be used? Or if they were dismantled like the rest of the ship? Somebody knows, I'm sure, so it'd be nice to learn. Thanks, Mike! Big respect for your willingness to "correct" oversights!

[@DistractedGlobeGuy]

Reciprocating engines were already outmoded on every metric by the end of _Olynpic's_ career (that was part of the reason she was scrapped rather than being given another overhaul). By that time, turbine drive systems had become more powerful *and* more fuel efficient, and all with fewer potential points of failure. Hull 400's engines would have been disassembled and melted down to be recycled.

All this with pen and paper god damnn I swear people were smarter back then

[@thomasbaker5105]

They used their brain??

[@Titanicplusdrums]

So true

[@shotty2164]

Have you seen the shit modern ships have on board? Yes ship building then, and engineering in general was brilliant, but the advances in technology since then is astounding. They weren’t smarter, they just worked harder and used their brain and muscle power more because of the lack of computers, and they did more with less than we have now, but they didn’t know any different.

My favorite video in this series so far. ❤❤❤ The Engineers, Greasers, and Firemen were the unsung heroes of oceanliner operations. It's haunting to see photos of Titanic's personnel, knowing most of them didn't make it through the sinking.

[@cameronsienkiewicz6364]

192 men shovelled 600 tons of coal a day.. that’s just over 3 tons of coal per man, per day, in conditions equal to hell itself.. those were true men, ESPECIALLY on the night/morning of the 13/14th of August 1912.. each one of em stayed at their boilers almost right up to the end.. some of them DID stay right until she split in half, and made the ultimate sacrifice so the people up top had a chance to survive the night

[@MichaelW-h6d]

Very interesting video! Have you done one about the human side of the engineers and boiler workers? Did any survive? What was their experience in the sinking?

[@haweater1555]

en.wikipedia.org/wiki/Crew_of_the_Titanic Summarized: 3 of 8 lead firemen survived. 45 of 163 stokers survived. 20 of 73 trimmers survived. 4 of 33 engine greasers survived. Other engineering crew, of which none survived: 25 engineering mechanics 2 boilermakers 8 electricians.

Starting in in the early 70's, I spent 20 years in the US Navy. I spent 14 of those years at sea down in the engine rooms. This video was very interested to me. While the boilers I was around used black oil then converted to diesel fuel, I did know a few old timers who had to shovel coal into boilers similar to Titanics. They all had huge forearms. 🙂 Thank you for posting.

[@landrover153]

Mike, we all owe you a debt of gratitude for the remarkable work, dedication, and information that you provide to us.

[@Sausketo]

You'd think with how sophisticated these engines were, you'd think they would have engineered an auto coal feeding mechanism like how modern pellet stoves do, less space/resources required for crew (there would still need to be some for maintenance and managing the feed rate of the coal)

[@csmith6237]

Modern pellet stoves require electricity. Where would you get the initial energy to power an auto feed?

[@Sausketo]

@@csmith6237 well in this case it could be driven off its own steam engine seeing as how its a steam train, or you could run an electric motor with a dynamo

[@csmith6237]

@Sausketo that would still require feeding a steam engine though, you're just adding extra weight and parts to a proven system

[@Sausketo]

@@csmith6237 only the steam generator/boiler requires fuel, so a small accessory steam engine would only require plumming

[@csmith6237]

@Sausketo so we would start with an initial main engine start up and let the feed take over? That could've worked I suppose.

[@oldtugs]

Why label a reduction gear as a turbine? Particularly when Titanic's turbine was direct drive, there was no reduction gear. Also, those propeller shaft bearings shown were not "force fed" lubricated. Each bearing had a small sump and a loose ring hanging from the shaft was dragged by fluid friction through the sump and carried oil that lubricated the bearing.

[@42lookc]
