The Engines of the Titanic

I completed my first model of the Machines of the Titanic. There now are two working engines and the Low Presure Turbine including the Condensers for the middle propellor. Also the boilers, bunkers and catwalks were added. Not all the tubing for the condensers are in the model, to maintain visibility. I used all the tips in the comments on the earlyer video I put on KZbin to complete this one.
Enjoy your trip in the lower part, below sealevel, of the Titanic!
The SketchUp model is not more available.
In July 2020 4 million visitors !!
In June 2021 5 million visitors!!
Errata: There are some misspelled words in the animation that I would like to correct:
4:15... "wich" should be spelled "which."
6:48..."firs" should be spelled "first."
7:09... Text should be "This kind of steam engine is called "triple expansion."
7:39...Replace "wich" with "which."

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.

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.

[@benmayne6159]

I am happy you got the engines right. Most people make the mistake and think that the titanic had "two reciprocating three-cylinder, triple-expansion steam engines", they were a common engine at the time. When in fact it had "two reciprocating FOUR-cylinder, triple-expansion steam engines" This was cause at the time there was no cylinder boring machine large enough to bore the low pressure cylinders diameter. So they used two cylinders the same size as the intermediate pressure for the low pressure stage, so they could build these bigger engines (30 000 horsepower, 22 000 kW). Making these engines four-cylinder, triple-expansion steam engines with the one centrally placed low-pressure Parsons turbine. This centrally placed low-pressure Parsons turbine is one of the reasons the owner wanted to go at full speed, even with "pack ice and iceberg warnings", if the two reciprocating engines were not run at full speed the low-pressure Parsons turbine could not be used. Dropping the efficiency of the ship a lot and increasing the amount of coal burnt for the whole trip, costing the owner more money in burnt coal as well as the ship might not arriving on time.

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.

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.

[@crgkevin6542]

I’ve always admired the cleverness of the Harland & Wolfe engineers that came up with adding a low pressure turbine to run on exhaust from the triple expansion engines. Squeezing just a bit more work out of steam that was already at less than atmospheric pressure before running it through the condensers. (Which are themselves quite impressive, given that they were effective enough to draw a vacuum in the steam lines...

[@sauter1]

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!

[@crgkevin6542]

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.

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.

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.

[@mark_chirnside]

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?

The condesers did a bit more than simply condense the steam into water because in doing so the pressure was reduced to signifcantly below atmospheric pressure. This meant the centre turbine had a larger diffential pressure accross it than just the 9 psi of the LP cylinder exhaust. As a result the turbine generated significant power once steady state running was achieved. The combined engines were in effect running in a quadruple expansion mode. For its time the Titanic was quite effcient.

[@Hoeishetmogelijk]

A very clear analysis. Thanks!

[@johneckert1365]

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.

[@simonchaddock4274]

@@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.

All coal-fired steamers of the era are black because of this. Check it out for yourself. Pretty much all of them. Coal is a dirty, and streaks. It also causes ash. Watch videos of the Britannic in hospital configuration. It's paint scheme will give away just how dirty these vessels got from the coal. Crew would spend a better part of a week just cleaning them between trips.

[@williamwingo4740]

I think I saw that one. It also said that it could take up to 24 hours to reload the ship with coal; it was a very complex, dangerous, dirty, labor-intensive process; and you couldn't do much of anything else while coaling. No wonder oil caught on quickly even though it was considerably more expensive.

[@taraswertelecki3786]

@@williamwingo4740 It was more expensive, but the energy density of fuel oil is much better than coal. That was why Olympic was converted to use fuel oil, which doubled her range because the coal bunkers were turned into fuel tanks. Fuel oil has twice the energy density of coal, so instead of burning over 600 tons of coal a day, Britannic burned about 250 to 300 tons of fuel oil a day.

Thank you very much for such a fantastic job in showing the engines of the Titanic. I was stationed on the USS Kitty Hawk which weighed about 85,000 tons, a bit bigger than the Titanic, except we didn't sink. Only once did I get to go into the engine room. It was fantastic to see the four prop shafts turning and even being able to touch them as they turned. It was fantastic, but after looking at your video, it wasn't anything like the Titanic. With all of the stokers working and the coal dust and noise, the Titanic was not fantastic, but insane, but really fantastic too, especially for those days. Thanks again for such a great video. C.

I stumbled across this video and was fascinated. I watched it 3 times. It's a very clear depiction but after the mechanics are understood one starts to think about life in the black gang or how they engineered and build this stuff in 1909. Amazing work. Adding the photographs was a great touch.

I love this!! I love the sound of those engines too. I understand that they are building a replica of the Titanic, but they're going to have a modern day propulsion system. I think that they should still have the same propulsion plant, however, the original style Harland And Wolf boilers should be modified to be fired wth natural gas instead of coal. Tanks for the natural gas would be in place of the coal bunkers. I have been a big time Titanic buff since Jame's Cameron's movie came out. I have adopted the terms "Port" and "Starboard" to refer to my left and right, and use those terms universally for everything. Last year, I had a knee replacement, and it was the starboard knee. I work as a dishwasher in a retirement home, and the kitchen that I work in, I like to refer to it as the "galley".

[@fatsolutions]

I knew realised that large steam engines had a small steam "starter" motor! Thank you for such an amazing video

[@ostlandr]

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.

[@fatsolutions]

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.

This video reinforces my belief that Titanic's reciprocating engines did not reverse in advance of the allision with the iceberg, as depicted in the Cameron film. They would be incapable of starting in reverse until the weigh came off the ship as the flow of the sea through the screws would keep them turning and create a large opposing torque against reverse movement.

[@robertbenoit5374]

its a Hollywood film. Great film, I seen it twice. You have to realize that nobody really knows what happened on the bridge as the entire bridge crew did not survive that night. It is assumed and often suggested that the officer on the bridge ordered all back full and hard left rudder. YES I SAID LEFT. WE DON'T SAY PORT AND STARBOARD with rudder orders. Certified Master Helmsman US NAVY. Although military, the orders are the same in the civilian world as well. It is to avoid confusion because Engine orders on a multiple shaft ship are port and starboard. The problem with that even if the engines went to reverse is that it would have been more like a twist than a turn. It isn't so much about torque as it is momentum. GRAVITY. first law of motion states that an object in motion stays in motion until acted upon by an equal an opposite reaction force. That means the force opposite has to be equal to make them go in reverse. the engines on a steam ship don't just reverse. Someone has to turn a valve and reverse the steam flow. Train engine and ship engine both work in the same basic idea that a valve has to force steam flowing the opposite way. This is one of the reasons steam is so inefficient.

[@kc4cvh]

@@robertbenoit5374 The orders from the bridge or the telegraph indication has no bearing on whether the screws reversed, it defies the laws of physics if they did. This is because: a) As long as the ship makes headway, the screws will continue to turn forward unless sufficient opposing torque is applied to halt them, much like the wheels on a motor vehicle b) There was no brake on the propeller shafts to provide this torque c) The reciprocating engines were not self-starting, they had to be turned with a starting engine to a certain position to start d) On the first half-revolution, only the high-pressure cylinder acts, so the torque is low. On the next half-turn, the intermediate cylinder begins to act, less the losses due to "cold" cylinders at the start. Then the low-pressure cylinders after one full turn, after even more losses. So, the reciprocating engines could not be rapidly brought to a halt in the right position for reverse starting and would be incapable of immediately producing the torque necessary for reverse rotation. And of course, the turbine had no reverse capability.

[@bhalachandrakamat5996]

[@78a67h]

For non engineers: At the time steam turbines were already in use and replacing the reciprocating engines, but on the Titanic it was decided to use 2 traditional reciprocating main engines because they had been proven in service and well understood by engineers. In effect Titanic's complete propulsion system was an early hybrid as it incorporated one small low pressure steam turbine, along with the reciprocating main engines, to drive the smaller central propeller as shown in the animation. The small steam turbine could not be reversed so it would be disabled when the ship was moving astern

[@katherineberger6329]

Further note: The first geared turbines were developed in 1911, well after Titanic had been designed. By 1917, all new naval construction used geared turbines. Titanic's turbine being fed by waste gas from the main engines was an energy recovery method; the turbine was the last stage before the spent steam reached the condensers for reuse as feedwater.

I was thinking the same thing!! Just the sheer size of the Titanic's engines is incredible. Between the boilers and the coal storage and the turbine and all of the moving parts it took up the entire bottom of the ship plus all of the people that was required to run it and their sleeping quarter's. I'm sure the sleeping quarter's we're very small but it was still something that was needed to operate the ship. So take all of that in to account and it took up the bottom of the ship completely I'm guessing by the video we just saw if it was to scale. Then compare that to today's diesel driven ships while still not what I would say small by any means!! But compared to the footprint of the steam engine and all of it operating components it's pretty amazing how much it's gone down in size, but up in power!

Very, very impressive animation of the Titanic's engine layout, with all the stages of steam this ship had to produce from the boilers to the different steam engine cylinders to compensate for the differing psi's of the steam for pressure and temperatures. The amount of coal use was staggering to imagine how 159 men had to shovel this huge amount of coal into the boiler's fire boxes is exhausting just to imagine the labor involved. Cannot think how much just this team of laborers were paid on a daily basis. Also, how did Harland and Wolf work out the fares for the differing classes of passengers that traveled on this immense boat in 1912 just to make a profit? People had to eat, drink, and use their respective bathrooms, how did Titanic arrange the human waste? Did Titanic use waste tanks or just jettison the wastes into the ocean?
