As far as I know, she even had enough steam to run her dynamos up to the very last moments which is impressive. She used all her lifeboats, did not list sideways. Too bad the ship as lifeboat idea did not work, so it escalated to heavy loss of life. However i think the ship itself performed very well compared to the damage she got. The Costa Concordia lost her engine room, main switchboard, main generators in the very first minutes in the flooding and had her emergency generator also quit periodically due to poor maintenance, people were struggling in the dark. This is unacceptable during an evacuation. Also listed heavily, which did not allow to use the lifeboats both side. Viking Sky lost her main generators hence full propulsion due to oil sloshing in choppy seas... I have the feeling that ship building and operating standards are falling heavily, despite the fact we expect much more from modern ships. Cruise ships are not ocean liners...

I enjoy your videos. Just for the record, boilers under these circumstances do not explode. They implode. They are full of high pressure steam. When they come in contact with cold seawater that steam condenses, leaving a vacuum inside. The boiler then collapses like a tin can. It can be very nasty, but not nearly as bad as a full on explosion. Also, the roaring steam you hear about coming from the funnels was most likely the safety valves lifting. Don't forget these boilers were at full working pressure to supply the main engines and accessories, and all of a sudden the engines are stopped. The firemen shut the dampers and drew the fires where they could, but the steam pressure is still going to keep rising because it has nowhere to go. Eventually, the fires died down or were drawn out of the boilers and the safety valves snapped shut again.

I like your videos and you obviously spend hours researching the subject. I spent over 15 years doing industrial / commercial boiler repair, I have seen several types of boilers go into a low water condition thus "Burning" the boiler, in other words melt down and literally burn the steel. To understand a "Boiler Explosion" look it up, there are many stories and pictures on this, this usually took place on "Locomotive type boilers" due to a low water condition, and when water was introduced onto the hot steel, the water would flash to steam and that sudden release of energy is what causes the explosion. The boilers on the Titanic are "Scotch Marine type boilers" the fire boxes were well below the boiler shell, that would allow ample time for the firemen to work the coal grates to break down the fires, and as one gentleman stated the actual steam area is above the boiler tubes themselves. By no means am I saying that It could not have happened because no one will ever know what really happened that night, but in all of the photo's and documentaries that I've seen, I have not seen any signs or evidence of an explosion. Thank you for what you do, you give a lot if information of that disaster.

Man, kudos to the guys in the boiler rooms, could you imagine knowing the ship is sinking and just staying down there to keep boilers running to keep the lights on and the ones that stayed down there to shut down equipment while water was rushing in? And the guys on deck too, having to shout over the steam, that would have been intense. Yeah I don't think I could have done that. The crew and officers who worked to save people and keep things together as long as possible really need more credit.

Just getting caught up on your videos. Regarding the possibility of explosion, first note that the boilers were not full of steam. They were mostly filled with water. Steam was created and occupied roughly the top 1/4 or less of the boiler. Water completely surrounded the furnaces, heater tubes and combustion chamber. Though the seawater entering boiler room six was coming in fast, it would not have dropped the boiler water temperature fast enough to create the pressure change required for an implosion. Note the operating pressure was 215 psi, the boilers were tested to 430 psi. In addition, the steam was not trapped in the boiler, it continued to exit the boiler until cool. There was a silent blow-off vent that, when the engines were stopped, sent the excess steam directly to the starboard condensers. This kept the steam pressure under control until the funnel vents opened. Underway on this trip, steam for the auxiliary units including generators and emergency generators came from two port side double ended boilers in Boiler Room #2 and two starboard side double ended boilers in Boiler Room #4. However, the auxiliary steam could be rerouted from any boiler, so we don't know if the two in BR#4 remained lit. It would have made sense to shut them down and transferred steam from additional boilers in BR#2. Note: The Boiler Room One furnaces were not yet lit on this trip, (usually used in port), and would have taken up to 12 hours to reach operating pressure. The men would have banked the fires beginning from BR#6 moving back to the engine room. The last ones remaining lit would be in BR#2 driving the generators, pumps, etc. There was no reason for most of the furnaces to remain lit, whether or not they were depended on to the time needed take to shut them down. I don't know about the sparks from funnel #3. It is possible that the starboard furnaces in BR#4 remained lit for the generators. But since the furnaces and related equipment were completely surrounded by water I can say is sparks from an implosion would remain lit and travel all the way through the uptakes to the funnel base.

I'm realy sorry for you that you had to re-upload alot of video's. I love your vids, keep doing what your doing.

I think I've watched every single video of yours twice by now, so much content packed into each one. I appreciate people with such passion for the Titanic such as yourself!

I read Mr. Lightoller's testimony to the US Senate, and the British Board of Trade, and I looked at some of the ventilation equipment on the Titanic, and here's what I think happened. There's an intake forward of the No.1 funnel which supplies fresh air to a blower to the boiler room #6. It's shaped like a large upside down J, and it has a grating in front of it. When the Titanic began its final plunge, Mr. Lightoller found himself underwater right in front of this intake, down into which was now pouring thousands of gallons of icy seawater. He was stuck to the intake by the suction, like a fish in a net. The boilers by this time, had been vented and depressurized, as you said. However, there were hundreds of tons of red-hot steel in the boiler room, and the water pouring down undoubtedly flashed into steam. This created a great pressure surge, and blasted the water back up the intake and blew Mr. Lightoller off the intake, and away from the ship, and right next to Collapsible lifeboat 'B', which was thrown clear of the ship also, floating upside down. Mr. Lightoller's survival story is an amazing one, and worth looking into. Peter Schilling wrote a song called Terra Titanic in 1982? I think that succintly describes these events, in German: Explosion in Machinenraum, das letze Boot hatte Glűck. (The last boat had luck. )

I want someone to do a video on all the changes that the Olympic went through during her career. Like no matter how small of a change I’d really be interested in finding out what they added, what was removed, what was changed.

I worked with boilers in a factory in the late 70s and early 80s. In that situation I would have vented the steam and raked the fire out. In my case turned the oil off.

New subscriber here. Love your content and happy the algorithm gods steered me your way. Keep doing what you do! Thanks again and I look forward to learning more about the vessels you cover.

Hello! I just wanted to say I love your content and I always get really excited when you post a new video! Keep up the good work!!

Your channel is so good! Thank you, i've always had a curiosity about Titanic. These videos are awesome.

Being a Union Steamfitter by trade I can attest to how incredibly loud steam blasts are. I was on a job they started blowing off steam and it was so loud our decibel meters maxed out and we were sent off the site until it was shut down and a silencer was put on the valve

Sam I’ve been here since you had only 3,000 subs… nice seeing you grow

Another really interesting video. I really enjoy this information. Thank for sharing these.

I love this channel because it gives a good showing of the mentality of the officers fire men and the rest of the crew on titanic

Great Video, have you seen Saving the Titanic? It's a great documentary, about those below deck keeping the lights running and doing the best they could. It came out in 2012, the Chief Engineer also went down with the ship. I think it shows a good job of what they went through during the sinking. Edit: Since it was in 2012 some things might be different from what we know now.

I enjoyed watching your videos. Educational to say the least. Thank you for your post (s)

Love re watching your uploads... Are you going to put a disclaimer on all your videos and future videos? It might save you from having to edit and re uploading.. keep up your amazing work and stay positive... Best wishes as always ☘️🚢🇮🇪🙂

The reupload of the reupload

Yes so amazing about the boilers. Thanks for researching this so well. Well any Titantic info to give us better understandings of what happened to the ship and the people before during and after the sinking.

Hello! I do enjoy your videos greatly! I also love the layout, and editing of your Videos! Please keep up the good work. I would like to say however, that some of your interpretations of accounts, and the physics that you place on the boilers, has some innacuracies. I have worked with steam for many years, and while it can indeed be explosive, it would not be under the circumstances you have described. Also the functions of the boiler accesories may need some clarification. I did greatly enjoy this video! And I am by no means trying to discredit you in any way, I am simply offering some deeper insight into the steam propulsion method. It is a concept that has been lost over the years, and one that people have misinterpreted the hazards and catastrophies of. Please, do feel free to contact me, and i would enjoy discussing this with you. I am a very big Titanic fan myself, and i love learning all that i can about her!

Great video thank you! Know that it was explained in Cameron's analysis of the tail section, that boilers imploding, was somewhat secondary to the huge freezer/refrigeration compartments (used to hold cold produce for entire voyage over and back!) that also imploded during to the pressure and change of cold temperature, and these two factors were the reason the tails stern section looks ripped/blown apart like paper compared to the front section.

I work in a power plant, and I can confirm, steam venting out to atm. pressure is MADDENING loud. It is very very uncomfortable to stand near without hearing protection. It is also worth mentioning, that the marconi operators on titanic could not hear all the messages they got in, because of the venting steam.

My great-great, and great-great-great uncles worked as stokers in the late 1800s and early 1900s and lived in Southampton. Both were invited to work on the Titanic but both declined as they had a premonition the ship would sink. I live in Southampton myself and if I were alive in 1912, I would have been able to see the ship sail out of the dock from my bedroom window. Love these videos, keep up the awesome work!

There is a theory that the flooding of BR6 actually came through the floor, not through a rip in the side as seen in the movie. A grounding of sorts combined with damage to the holds and forepeak combined with the "small holes theory". I believe the holes amounted to know more than 16² ft.They also lit up BR1 for the first time of the voyage to provide electrical power. Love your videos.

Great video. Very informative. Well done...

Another good video by you. I thought I knew a good deal but I never considered the boilers. I do know I have read about the two incidents involving Lightoller being sucked against a grate so your explanation does give some merit to a possible boiler explosion.

11:28 So the boilers are falling? The few survivors in the lifeboats had seen the Titanic's rift in the pitch-black darkness, and many more had heard a few repeated thudding explosions coming from beneath the water as the stern slowly began to sink. Such a definition of a loud and sudden sound was mainly given by passengers who did not even have an indirect connection with working at sea, suggesting that steam boilers were exploding in the bowels of the steamer. Which in reality could not be, since the visible boilers from boiler rooms No. 1 and No. 2 are intact and the hull in the area of the other boilers is not damaged. Even Second Officer Charles Lightoller joined the majority, stating: "I have heard that many are convinced of this, while others doubt it. I think the boilers have exploded." To clearly distinguish the nature of the " sea " sounds and skillfully associate them with something else, you need to "exist" inside them for some time. Passengers and service personnel followed an uncomplicated associative chain: a loud bang means an explosion, and the contact of a hot object with cold water could cause an explosion of boilers. Much more accurate is the evidence of the minority, to which the roar of the implosion, the destructive displacement of air from the bowels of the stern, the peeling of the skin, the collapse of the floors, the separation of the front part of the propulsion system, resembled the sound of a thunderclap. Lookout George Simons recalled: "In less than two or three minutes, the stern rose vertically. There was a sound like a thunderclap, which is usually heard in the distance, and soon she disappeared from sight." Stoker George Beechamp said: "The bow section slid under the water first. I watched the stern, and then she sank. I heard a roar like thunder." Coxswain George Rowe agreed with his colleagues: "It was not an ordinary explosion, it was like a distant thunderclap." The most detailed story with a hint of the implosion of the internal aft rooms was presented by major-yachtsman Arthur Poshan, who has experience of navigation: "I heard explosions, rather, a rumbling sound - not sharp, but strong enough. I can't say it's as loud as a thunderclap, a cauldron explosion, or anything like that. I dare say the decks "collapsed" under the pressure, pulling the steamer down with her nose forward. The huge mass and the air between the decks caused the "explosion" - that's my theory. I do not know if this is correct or not, but I do not think that the boilers exploded. Perhaps it's the pressure: the enormous mass pulls the ship down, the water rises up, and there is air between the decks."

You are doing really great 👍 keep it up.

Just found this thanks so much for keeping this piece of history that will be gone so sad in a few years 😢

I enjoy all your info, thanks, very informative.....

If you throw cold water on a vessel pressurized with steam, it will IMPLODE, not explode. Because as the steam rapidly cools and condenses back into water, it creates a vacuum. For a good example of this, I refer you to the Myth Busters video of the train tanker car implosion. In the shop, they filled a 55 gal drum with steam and then quickly capped it. After a period of time, the barrel imploded! So it stands to reason the same would happen to Titanic’s boilers. The results could be just as catastrophic though!

You have earned yourself a new Subscriber, i have subscribed😎

Very informative I enjoyed

Keep up the great stuff

Speaking as a British guy I'm loving this guy's southern accent.

Good question and interesting information

That reasoning does also fit the loud explosion the passengers heard before the final plunge, and it would also damage the watertight bulkheads in those sections.

Thank you for all the information that you provide. I saw "A Night to Remember " as a child. It haunted my night mares for years. Somehow, the technical and human details have helped understand what happened and why it happened. James Cameron's movie was wonderful, bit this website pulls it all together for me.

Hi Sam! I just got the same Titanic model you have. At least I think so. They look identical.

The testimony of lead fireman Frederick Barrett should be seen as accurate and without bias. He was present, alongside the engineering group, inside the boiler rooms and was actually inside boiler room #6 during the impact. He was one true hero that did survive

Most awesome vid!!!!!!!

Wow very interesting,I've had the same kinda theory since I was 12 but my history teacher didn't want to hear it🙄Saw the movie when I was 10 but started learning about the Titanic as far as 3rd grade once learning about the Titanic it fascinated me of how people were way before I was born&how things were slowly developing as their "technology"was back then. Trying to imagine of how that ship sank with over 1,000 people on board in cold weather&freezing water brings tears to my eyes.😢Thanks for sharing this video I hope some people learn more of what they think lol.👍😆

Could you do a video about the implosion of the Stern from the eyewitnesses?

Thank you

Hi i think it would be epic if you did some episodes on 1st hand accounts from the ship. Hearing you describe and talk about them would go pwrfect with your library.

Please Do SS Estonia And Keep It Up Videos Are Great

Hello Sam You are the best

The coals inside the furnaces within each Scotch boiler were quickly removed by the firemen in the boiler rooms who essentially raked the red-hot embers onto the stokehold flooring that was two feet above the ship's Tank Top level. When Titanic's engines were brought to a stop the 215° PSI head pressure at first was diverted into the large condensing ducts and circulated back into the closed system before eventually being diverted to escape through exhaust conduit that was built into the liner's massive funnel system.

I know the stern was destroyed because of water pressure on the way down and the ship breaking had alot to do with weight and stress, but could it have been possible that the boilers exploding had anything to do with the ship breaking in two and the stern being so damaged. Survivor testimonies talk about hearing explosions which could have been just the break itself and stuff inside the ship moving around. I feel like it could it be a factor. The lights were on for most of the sinking so it's got me thinking. Great videos by the way!

A factory boiler nearby me blew up one night. There was no mistaking a boiler blew up, for a radius of several miles the ground shook violently. I would tend to think if a boiler in the Titanic exploded, the ship would have had a very noticeable, messy, violent end.

Steam is LOUD. I recall the steam whistle in the old depot on Parris Island could be heard (outside) virtually anywhere on the 8,000 acre island. I described it as "a thousand cars squealing tires at once".

I've always been impressed that James Cameron knew to show the venting steam.

You know what, I did you so nice and wholesome I will follow on principal!... Also you make nice Videos. XD

With the state the stern is in , I believe an explosion of some sort did happen on the final plunge

The boilers may not have exploded, however, when the ship broke apart, the steam pipes were severed and instantaneously released the steam pressure. I’m not sure of how all the boilers were plumbed together, but it’s my understanding the rear-most single-ended boilers were used to generate power. These boilers were the priority of the engine crew. To operate the dynamos to generate enough electricity, these boilers were under steam pressure through the end. The venting of steam was more than likely done to the boilers that operated the propulsion engines.

And Lightoller described the coldness of the icy water as like a thousand knives stabbing into his body.

So from what I’ve researched is that the boilers are still intact on the ocean floor which doesn’t indicate much of an explosion. It could’ve been the rush of water forced out the burning coal idk. Also, they say the boilers were so heavy that they were mainly held in place by gravity and were only secured by light piping (for steam) as the titanic was close to a 45° angle, these boilers could’ve broke free and slammed into the bulkheads. Also, the other noises that can be attributed is the pressure of the water on the walls of the passenger decks being so high and the walls giving way and bursting. Some other noises can be also attributed to the ship being pulled apart until the final snap when it snapped apart. As always Sam, these are all hypotheses, and up for debate. I enjoy watching your videos. Keep up the good work!!

The cold water had cooled down the boilers, I'll use some railroading tech here A steam locomotive and a steam ship are practically the same thing so I'll use some real examples If you notice a steam engine runs lowder when in the cold so the vented steam would have been louder sense it's colder but usually a boiler explosion is due to to hot of fires and the boiler gets to hot and with no cool water to cool the boiler the boiler detonates So I think rooms 3&4 were not getting enough water and we're about to detonate but the sudden rush of cold water may have caused a chain reaction but idk it was over a hundred years ago but it's fun to theorize

Quite possible that seawater hitting hot coals could produce a local stream explosion rather than a boiler actually popping. Boilers tend not to explode if cooled and are probably too strong to implode due to cooling by inrushing water. Evidence suggests that some of the boilers found on the sea-floor had some evidence of implosion but I would be very surprised that any would have survived the pressure at that depth without very significant damage, so it is hard to tell when this damage took place. Water tends to flash to stream on hitting very hot surfaces and this could propel hot coals and such out of any available exit. They other thing people reported was stuff breaking free inside the ship and of course there is very significant damage done to the stern of the ship due to the collapse of trapped air.

The only question I have every time I watch one of your videos involves the wall/ceiling behind you. That wainscoting behind you is higher than normal relative to your desk and computer monitor. Additionally, the white drywall portion above it appears to be sloping toward the camera at the top, which makes me think you are shooting these videos in your cramped upper half-story bedroom where the walls only go 1/3 of the way up, and sloping ceilings come down the other 2/3 of the way. The last clue that makes me believe this is the matching beadboard door to the left of the screen, which seems to be access to an eave attic storage area. Am I correct in my assessment?

thank you

cold water on a hot boiler does not mean an explosion. its possible however that it could implode the boiler. the main cause of a boiler explosion is allowing the water to get too low, and it gets lower than the crown sheet (the plate above the fire), which causes the plate to overheat and warp, which eventually pulls loose from the staybolts and its a chain reaction as the pressure drops, and the now superheated water flashes to steam causing a massive explosion.

only boiler room 6 was severely compromised after the impact. Those boilers were at full temp and pressure since just prior to the call to put the engines "full astern", the boilers were operating at full capacity since Titanic was sailing at FULL AHEAD. After the collision, and since the ship was at ALL STOP, the dampers were closed and the boilers were venting steam and lowering pressure. By the time that Titanic sank low enough that the water spilled over the bulkhead at boiler room 6 and overwhelmed the pumps actively pumping in boiler room 5, the boilers were much lower in pressure and temp. The only boilers that were being fired at full power were the ones that were sending power to the electrical systems. By the time the boilers were subjected to seawater, the heat and pressure in the system was much lower than it had been at the time of the collision

Probably wasn’t a full on boiler explosion but probably some of the safety valves opening and venting off the boilers as either they broke, suddenly shut down, among other scenarios

Whoever disliked this video doesn't have a good taste of history

So, if a boiler explosion happened, could that have possibly been the reason for the breakup of the ship on the surface? If the bottom was blown out amidships, it would explain it breaking in two.

What do you think happened to the "Marie Celeste?"

In the film A Night To Remember , it shows the men in one of the boiler rooms were ordered back to the fires to stop them exploding .

I don't believe it was an explosion but a sudden release of steam that released Charles Lightoller and when the second funnel fell it had electrical conduits that allowed for the top of the funnel to be lit for visual recognition from a distance

Do you think a small-scale boiler explosion could have been a contributing factor to the Titanic breaking in two?

Did u know that Kim il sung was born on April 15th 1912

if i spent as much time focusing on my law degree, as i do watching your videos, I'd be a first class student

It’s possible that it had a dead-man lever to shut down all boilers in the compartment at the same time, allowing for a quicker escape.

At 10:25 or so you mentioned how the 1st officer was saved by a blast of warm air. Sounds a lot like 1 of the 3 survivors of the Hood being forced to the surface

Have you played stormworks you need to its so good for history about ships in a realistic way like it has this detail of steam pressures

Hi , thanks for your video . I am curious , do you plan to buy and build the new Lego Titanic --set # 10294 _ $ 629.99 ? Your videos are very good and your knowledge of the Titanic is excellent . Take care, Dreamer 

I've always thought that a boiler or boilers exploding caused the breakup to happen.

Boiler room 3. The second boiler in the room away from the door had a structural failure in its main pressure chamber and the boiler exploded from overwork as the titanic was sinking. The heat weakened the metal in the pressure chamber causing a catastrophic failure... dont ask how I'm sure of this you wouldn't believe me

Hey there! Could you do some videos on the Chernobyl disaster?

I'd like to learn more about the boilers that imploded. I've heard conflicting explanations, it would be cool to have a definitive answer.

Could HAVE been the reason, nor could OF been the reason.

I think there were some explosions at the end, but the stokers managed to pull most of the hot coals from the boilers

I know I'm late to this but I'm wondering if boiler room 4 exploding might be a catalyst to the breakup. Boiler 4 is about where the ship split and a steam explosion would compromise the structure.

Video idea! Why did the funnel collapse?

As evidence for releasing the steam there are the radio messages from 12:26 clearly say "can't hear nothing for the noise of steam"

Lighthauler might have been pushed by simple air escaping the ship as water rushed in, I think it has nothing to do with a fire/explosion

I keep thinking the "active" Boilers may have "imploded", versus "exploded"? This may have caused a majority of super heated water to disperse within the ship, leaving hot water to raise Litower(sp?) towards the surface?

Lightoller getting sucked down not once, but twice? That's traumatic

so if they had time to shut the dampers and vent the steam, and venting the steam is LOUD, then the venting started when the first loud sounds were heard, meaning they down there in boiler room 6 while Titanic was brought back from propellers off, to propellers half speed, to propellers off again (and then Boiler Room 6 was vented) ? ?

one thing in seeing the cameron clip vs. another clip in a previous documentary makes me wonder something. In the previous clip the venting process the mighty horns of titanic were blowing as well. in the cameron clip of course they wasn't so it makes me wonder which is the factual actual for lack of a better term. thinking if so on a calm quiet cold nite it would've been heard for MILES. that alone would've been a definite red flag for many and if not for the ice field would've been a call for help in itself or should've

I wonder if KZfaq Corp knows about section 107 of the copyright act 1976🤔 keep educating bro🤘🏻

Want I just dont understand is how they allowed the bulk heads to spill over to other comparments. What is the use of bulk heads if they spill over and then everyone is filled with water?

Hello Historic Travel I love your videos and I have a video idea and it is a what if theory and my video idea is what if Titanic sank listing on it's side and how it would sink I hope you see my video idea (:

id like to see a what if, of what would have happened if the titanic boilers exploded?

Would a boiler explosion or a couple exploding blow off parts of the keel? Could that be why keel plates were found in the debris field rather than attached to the ship?

I reallyyyyyy want a model of the ship like this! Where can I get one?

I have had this silly theoretical question I've been wondering for the longest time. Could welding over the holes in Titanic have saved the ship? I know welding didn't exist back then and it's not like the crew had any spare metal laying around but I think it's still in the realm of possibility since the gashes themselves were slim and I think it would just be an all around fun what-if scenario
