What If The Queen Mary Hit Titanic's Iceberg?

[@cardiffdillon]

The Costa Concordia incident proved that large, state of the art passenger ships, built to the latest SOLAS standards, can still sink after striking a submerged object. They were just lucky that it didn't happen hundreds of miles from the nearest assistance.

[@curtisrobinson9696]

it also proved that the intercom is only as useful as the captain speaking into it

[@yknott9873]

And Costa Concordia suffered another dreadful design flaw, that EU shipping experts had tried unsuccessfully to warn the EU about for over ten years. Modern cruise liners all resemble the Costa Concordia, and the danger (which is what happened to that ship) is that if the hull is opened on one side, water will rush in and capsize the ship to the other side. There are many photographs of the hole that sank Costa Concordia, with the rock still in it, high-and-dry after the ship capsized. The Island of Giglio recovered the rock and built it into a monument to the tragedy.

Not to mention, that Titanic's crew was only aware around ... 40 or so minutes after the crash that the ship was doomed. On the other hand, the crew of the Queen would be almost immediately aware of the situation due to the intercom system, and wouldn't lose as much time as Titanic's crew.

[@K9TheFirst1]

Not quite. The bulk of the time taken on Titanic to realize what was going on was due to the fact that she was a very big ship, and they had to walk around to investigate... Nevermind, you have a point. WIth a widespread telephone system on board, all sections of the ship could have informed the bridge of what areas were damaged and how badly within minutes.

[@matthewthetransportguy3515]

@@K9TheFirst1 yes but of course the crew in the damgaged area, boiler room 6 were probably too distracted to get shut the dampers, shut everything down and get out of the boiler room before it flooded. And the rest of the engineering crew would have been busy at getting the pumps online and fight the flooding so other people had to come down and see what was going on

[@mityaboy4639]

the Titanic’s crew had the “issue” that they believed that they are on an unsinkable ship. which slowed down their efforts at first. its almost as if “this is not necessary, just precautions” and the size of the ship did not help to notice how dire the situation is from the first second of the hit. i am not saying the crew was at fault, just they ate up the marketing BS too (which i think even White Star Line thought its true) so the loss if time and reluctant start of evaluating the ship is indeed part of the missing full intercom, but also the fact that the Titanic was marketed and believed to be unsinkable

[@stevenkarnisky411]

ThebTitanic's crew knew very well that she was not "unsinkable". The whole thing thing was overblown advertising hyperbole. A newspaper article called Titanic "practically unsinkable" due to her advanced safety features for 1912. That article became the basis for the myth.

[@jaimeunwin8278]

Very true but had the titanic not sank how long would it have taken before safety features were improved would we have carried on thinking each new ship was more unsinkable than the last especially if titanic had hit and not sank?

[@scottreich1207]

Without Titanic hitting the berg, I doubt that SOLAS Conventions would be enacted. The safety of life at sea conventions of 1914 were a direct result of Titanic's sinking. They, among other things, provided for enough lifeboats and 24 hour radio watches. QM's safety was greatly enhanced by improvements made after the loss of hull 401.

[@thomasackerman5399]

If it wasn't Titanic that struck an iceberg, it would've happened to another ship eventually. It was only a matter of time. Just a few years prior to Titanic in 1907, the North German Lloyd liner SS Kronprinz Wilhelm struck an iceberg and suffered damage to her bow. Fortunately, she managed to limp into port. It was this incident and the RMS Republic sinking that helped fuel the mistaken belief that ships were either too safe to sink or would take so long to do so that help would arrive with plenty of time to spare. The lifeboats, of course, acting to ferry passengers and crew to the rescue vessel. But the Kronprinz Wilhelm accident illustrates that given time and no change in procedure, something like the Titanic disaster was all but inevitable.

[@CptRennett]

The funny this is that the lessons of the titanic were put into titanic’s still under construction sister, the Britannic. It was retrofitted with massive electric lifeboat davits. When the ship sank, even with a heavy list and only 55 minutes. Everyone got into a lifeboat and off the ship. That didn’t save all of them from the propeller unfortunately. And that was a retrofitted Titanic, so I think a ship entirely built with the titanic disaster in mind would have no problem ensuring the safety of its passengers.

Britannic was out of this world unlucky,just like her younger sister Titanic.Due to war,watertight doors were always closed but were opened for 5 minutes from time to time for crew to pass,and thats when she struck a mine.The mine caused damage that jammed the watertight doors open.Im positive she wouldve made it without that misfortune.

It was interesting seeing that the Queen Mary almost did sink in very heavy seas too. It needed to roll about another 3-4 degrees and it would have rolled over.

One thing to keep in mind about "Mauretania" vs "Titanic" was that "Mauretania" had been built with a loan from the Admiralty with the idea that she (and her sister-ship "Lusitania" could be converted into armed merchant cruisers in time of war. So, their construction was done with naval requirements in mind.

[@ToreDL87]

@@streamerbtwa229 Actually it was, because that "double hull" was actually just the coal bunkers. It didn't help the Lusitania at all, and is even speculated that it worked against her. Double hull is a double edged sword, it's more weight on the sides which can propagate issues with list, even the Queen Mary was known for heavy list. Fill these spaces with water and you get a list prohibiting launching of lifeboats on the opposite side, and water has a history of breaking through coal bunker bulkheads. The issue wasn't the way those big ships were built, it was that they were built before proper emergency and rescue procedures were put into place to make sure they could be used safely.

This was such a captivating video on the safety features of the wonderful RMS Queen Mary and how they would fare in a similar collision as Titanic. Despite over a dozen visits to her in Long Beach and building several models of her, you shared many details that were previously unknown. Most notably, it was interesting to learn that she too had longitudinal bulkheads like the Lusitania/Mauretania, had caps at the top of her watertight bulkheads to potentially confine flood water, and ribs on the lifeboats to allow them to pass over the riverheads in the event of a list during an evacuation. The question that next comes to mind is, how would a modern ocean liner like Queen Mary 2 handle such a collision? Of broader curiosity, how would a less robustly built standard cruise ship handle this? As for the RMS Queen Mary herself, please spread the word on her current plight as repairs are so urgently needed to save her for future generations.

The thing people tend to forget when they compare more modern ships to Titanic is that Titanic herself influenced the design of these newer vessels.

And, to the credit of the crew, Titanic remained afloat longer than even her designer predicted. It just wasn't long enough.

[@K9TheFirst1]

Queen Mary Sinking Scenario: Generally, I agree that QM would have had a much better chance at surviving a collision similar to Titanic's. However, I would like to bring forward that QM was both heavier and - all other factors being equal in the scenario - would have been going much faster than Titanic. That changes a lot of factors that can affect everything else, as the crew may have less time to react from seeing the berg, to the ship receiving more damage, to a number of other things that cannot be accounted for, and can affect the scenario further down the line. So again: I agree that QM had all the advantages that Titanic lacked in construction and cultural experience (the QM's entire career was with Titanic in living memory for one thing, and Titanic was the cause of a lot of the changes that were incorporated into QM), and as British steamlines recruited officers from the Royal Naval Reserve, they would have had the training and discipline to deal with such a crisis. But when you have thousands of people crammed into what is in comparison a very small can on a very big ocean, it can easily turn into disaster even with the best of effort. 3:00 - 'Why didn't Titanic have a double hull?' Because the probability of the ship taking the sort of damage that would require it was very unlikely. Titanic was built with the most probable collision scenarios of ship disasters up to that point: Ramming something, being rammed, and running aground. All of which are more likely while close to shore and/or port, with rocks that may or may not be properly charted, and crowded shipping lanes, and are thus typically at half or slow speeds. A full speed side-swipe - while potentially possible - was as close as you can get to an Outside Context Problem while not relying on fantasy or sci-fi. Furthermore, remember that Mauretania was built to near military spec, due to being largely funded by HM Government with the expectation of being used as an auxiliary cruiser in wartime. Hence the side compartments - She and Lusitania are (in the most strict definition) the largest Protected Cruisers in the world. Had Cunard been able to build them normally, the coal would have been stored more like Titanic. QM's double hull/fuel bunker setup has more in common with Olympic's Post-War configuration, after she was converted to burning oil. 7:05 - Titanic did develop a list, though while it certainly affected boats on the starboard side, it wasn't as bad as you made it out to be. In comparison, Lusitania - Mauretania's sistership and in possession of the side-bunkers - leaned far enough over to genuinely make lowering boats impossible, and genuinely would have benefitted from those rails on the sides of the boats.

[@matthewrafaelechate4017]

look no further, Olympic is a testament o how well-built these sisters were..!!

[@MrChickennugget360]

Factor he does not seem to know or remember was that Lusitania and Mauritania were both subsided by the British Government to be used as auxiliary Cruisers- In fact both were built in response to J.P. Morgan buying up ocean liner companies (White Star Line and Holland America for starters) (this was in the INM company) Cunard was in danger of loosing out to rivals so went to the British Government who helped pay for new Ocean Liners thus cost was not as big of an issue as with Olympic Class which were not built with a subsidy.

[@AlextheHistorian]

I hope nobody here thinks I was trying to put down Titanic's design. I wasn't trying to make it sound like she wasn't well built. As for the collision scenario, I was estimating that all factors were the same, that INCLUDED speed. In my scenario, Queen Mary was traveling the same speed as Titanic. I was trying to eliminate as many outside variables as possible in order to understand the difference in collision reaction. Also, I know that Lusitania and Mauretania were government subsidized and built to better war specifications, I guess I just assumed that with the advent of double hull design, I thought every company would want their ships to have it. Especially when a ship is branded "unsinkable".

[@MrChickennugget360]

@@AlextheHistorian I think the extra cost was why. plus part of the extra plating was since they were being intended to be Aux Cruisers. Just think in a different time line we might have had HMS Lusitania and HMS Mauritania running around escorting conveys. As it happened only Olympic sank a U-Boat. The fact that the Cunards' were partly government subsidized to serve war purposes gives me some fantasy today that the Government would subsidize construction of Modern Ocean Liners that could be converted to use as hospital ships. This is particularly reasonable since the Navy is not happy with Comfort and Mercy since their Tanker construction makes them very slow so they take forever to get to a disaster area. A modern Ocean liner could be built specifically to be easily converted to a Hospitable ship within a very short time (the crew could even be duel merchant Marines so that they would be trained for both)

[@stevenkarnisky411]

Or, they could rebuild the fastest ocean liner of all, the S.S. United States, which sits, gutted in Philidelphia, ready for an internal rebuilding. No other liner has ever beat her Blue Ribband crossing time of three days plus. Her hull plating was built to military specs. at an inch and a half thick. She is faster in reverse than any other liner was at full ahead! As a hospital ship she could get anywhere in the world in a !atter of days.

[@GlamorousTitanic21]

4:10 In answering to this, Titanic was built to be a passenger liner first and foremost. Mauretania was designed to Admiralty specifications with the understanding that by funding their construction, the British Admiralty would retain the right to requisition the Mauretania and Lusitania as armed merchant cruisers in war. Having a double hull and coal bunkers running along the side was in line with British warship design at the time.

[@btomimatsucunard]

Great video! Towards why the Lusitania and Mauritania had double hulls but the Olympic and Titanic did not, I believe it was to how the two classes were financed. The Lucy and Maury were partially financed by the Royal Navy, and as a result were expected to be converted to auxiliary cruisers in wartime. As part of that, their mechanical spaces had to be protected from shells, thus a double hull was worked into the design with the coal bunkers acting as the buffer, similar to warships at the time. Olympic and Titanic were privately financed and thus did not have that same restriction placed on them. I suppose the thinking for the time with private enterprise was that the subdivided hull would be enough, and that the most likely damage to occur would be from the bottom through groundings (IE the strange 1909 accident the RMS Empress of Ireland had). Any damage from the side would likely result from collisions with other vessels, thence why she was rated for any two compartments flooded or the first 4.

[@Railman1225]

wait, i thought the Empress of Ireland was involved in a collision, not a grounding? edit: yup, she was.

[@TheRelativy]

I would assume, that the damage to the ship is proportional. So Queen Mary being longer than Titanic, should get around 310 feet long breach. It can also be supported by the ship shape. Titanic damage is where ship is getting narrower toward the bow. Breach end where the hull is getting straight. So Queen mary would suffer floding in 8 compartments. The question is if the damage would be deep enough to breach oil tanks. Most likely not. But with 5 fully floded compartments her bow will dip below the waves and water start getting into the ship from the top, above the watertight compartments, and then ship is doomed anyway. It would most likely take much more time to sink.

Just a technical note: The iceberg that was struck by Titanic did not "puncture" the steel plates. It buckled (or bent) the plates and popped rivets that held the plates together, compromising the watertight integrity of the ship in those 1st 5 compartments.

Quite a good summation. QM wasn't exactly double hull (that's only for modern tankers and container ships) but she did have an 'inner skin' as shown which would protect against the berg penetrating into the main spaces. As mentioned, it could possibly breach the fuel/water tank(s) as well but the list would be slight as there's not a lot of difference in the weight of heavy oil (around 900kg/m3) and seawater at 1024kg/m3. Any list could be counterflooded by the tanks on the port side. If Lusitania had been oil-fired, she could possibly have survived as the bunkers would have been oil/water tight. However, the same inner skin was applied to Britannic, and she still sank!

On Titanic they ended in a wedge, which may have focused stresses and caused cracks to extend down the side of the hull beneath (think like the groves int he top of a bar of chocolate making it easier to snap). on Britannic, they had swapped those for a rounded end to the joints which dispersed stresses evenly and avoided cracks.

[@TSR1989FF]

When considering that the first passenger ship in the world with a double hull, the *SS Great Eastern* , survived a larger amount of damage on a voyage than the Titanic, and made it to port, says it all about the benefits of a Double Hull. RMS Olympic was retrofitted to have a double hull (among other features), so at least some good came of the tragedy. I think also that the Titanic's crew trying to run hoses from the engine room to assist with damage control (once the scale of the damage was known) is often overlooked, despite the ship having the most powerful marine engines in service at that time. The cruel irony is that this was among multiple things on-board that could have kept her afloat if implemented sooner / at all.

SS Great Eastern was like that because it was constructed by engineering legend Isambard Kingdom Brunel.

^ Disagree. There were - in hindsight - multiple materials and resources onboard that would have brought the flooding under control, but only one of those was actually attempted (running hoses from the engine room to aid the pumps), but too late to tip the balance. The disaster did lead to radical rethinking of nautical safety though, and was less ghastly than it could have been. (see the fate of the Naronic for why)

My opinion is that amount of damage may have still sunk the Queen Mary. One of the prominent features of the titanic sinking is she only developed a minor list. Most of the passenger ships since up to and including the Costa Concordia capsized while flooding and sinking. Another Prominent example is the Andria Doria. She also listed greatly and layer over on her side as she sank. I believe the regulations now require the cruise ships and ocean liners be designed and equipped to be able to completely evacuate all the passengers and crew in somewhere around 45 minutes to 1 hour. However, the costa Concordia totally failed in that mission.

[@jimjolly4560]

Great video, with an excellent explanation of many of the different factors. I just have one quibble: at 1:07 you mention "a rare formation of ice that created an overhang." Like you, I am not a maritime engineer, but I was taught that as icebergs are 90% underwater, almost all of them will extend much further underwater than they do above the surface. It would be possible for severe damage to happen below the waterline, without the iceberg ever touching the ship above the water. If I get back to Long Beach, I will visit the QM and contribute to the restoration fund. Thanks again for a fascinating video.

[@AlextheHistorian]

Those weren't my words, National Geographic said that there was a nob of ice that jutted out away from the main berg. That it was a rare formation of ice creating an overhang. If it wasn't for that, she would have cleared the underwater part of the berg by several meters

[@toddkurzbard]

That is correct. I noticed that. Underwater 'spurs' are actually fairly common on icebergs. One might have them, another won't. I believe it is due to uneven melting between the exposed (above the waterline) portion of the berg, and the submerged part (which is actually much harder and therefore a lot more resistant to melting).

[@tomriley5790]

I think it's unlikely she would have sunk, obviously she could have however one of the key differences is that there was a better understanding of the fracture characteristics of steel and therefore the steel that QM was built from would likely have behaved in a less brittle and more ductile failure - leading to less water ingress. QM going down by the head would likely have been able to deploy her lifeboats and there were sufficient lifeboats for her passengers, all lessons learnt from the Titanic. Good video I agree with your conclusions! Interestingly although I can find a turning circle for the titanic, I cannot find one for the Queen Mary, Titanic had a famously undersized rudder for her mass, I doubt QM did - it's possible QM would have missed the iceberg completely.

I would add the challenge of making the damage relative to size. While the Titanic's damage was large it would be less to the Mary, therefore I would increase that amount of damage to correspond to the size of the ship. Secondly, the Titanic was driven through the water for 5 to 8 minutes again after the accident, which overpowered the pumps. I'd like to add that to the equation just for fun, it adds a few more variables to the comparison..

[@donobrien9220]

The reason the hull breached so easy was the lack of knowledge at the time of carbon content in the steel and how it becomes brittle in severely cold water temperatures. The steel plates acted like glass in those cold water temperatures. Unfortunately they did not understand impact properties at low temperatures and how critical the carbon content of the steel is at those temps.

[@AlextheHistorian]

They have never found evidence of the steel plates being fractured or ripped from the impact with the iceberg. What they did find was missing or torn rivets. Rivets had to be slightly weaker than the steel plates so that the riveters could pound them in by hand. And the rivets didn't fail because of weak steel, they failed because two massive objects far greater and heavier than them collided.

[@robertdevito5001]

Carbon steel had existed for nearly 2,000 years by the time Titanic was built, the reason the hull breeched so easily is because over 40,000 tons of ship met hundreds of thousands of tons of ice while going 20 knots... for a scale reference, make the best thimble you can out of any material, but it has to be foil thin, then place it on the sidewalk and smash it with a hammer. The material and temperature won't matter, it's the force of the hammer (representing the momentum of a massive ship) trying to dump its energy into an immovable object (the sidewalk, which represents the iceberg) with a relatively thin wall between the 2 (the thimble which represents the hull of the Titanic). Ships this big going this fast don't bounce off of things, either the thing they hit moves out of the way or something breaks.

[@geigertec5921]

The QM would have also sunk just in a different way. The bow would have dipped below the waterline and the starboard oil tanks would become filled with sea water causing a list to that side. Water would also enter the ship through other unforeseen means such as unlatched/improperly secure or open portholes or unsecured gangway doors. This would lead to flooding on the starboard side eventually culminating in a full capsize event. The survivors would then have to contend with an ocean full of Number 6 engine oil whose fumes would easily overwhelm many of them. The lifeboats would probably allow most or all of the passengers and crew to escape however assuming there was order and they were filled to capacity.

[@PassiveSmoking]

Longitudinal bulkheads aren't always helpful Lusitania rapidly developed a massive list after being torpedoed, because the coal bunkers on that side of the ship flooded rapidly. Andrea Doria also developed a huge list after one of her fuel tanks were punctured, because the tank on that side filled with water whereas the tank on the opposite side was empty.

[@keepmahaney7412]

[@angellight495]

The Mauretania and the Lusitania were financed by the British government with the provision they be designed to serve as armed merchant cruisers in the event of war. This does explain why the Mauretania had the coal bunkers placed on the side (to protect against shellfire as the submarine was an unknown menace at the time of her construction) and why she had the full double hull. No I imagine with the Olympic & Titanic the designers assumed that there was no possibility that more than 4 compartments could possibly be breached in any conceivable accident or collision so the addition of a double hull would have been considered an unnecessary expense.

[@yknott9873]

@@Kaidhicksii Too late by then. Master's instructions for Lusitania / Mauretania included that if the ships ever assumed a certain list and did not then right themselves, the Master was to abandon ship at once. The cause of this would be penetration of a coal bunker and the loss of its buoyancy on that side - Empress of Ireland gives a grisly example of what could happen. Lusitania suffered two more debilitations; a coal dust (they think - the ship was not carrying enough munitions to create an explosion like it suffered) explosion that (apparently - the wreck has collapsed on the side with the torpedo hit, and it can't be examined) blew out part of the bottom, and once the ship listed the up-side lifeboats were almost unuseable as they dangled inboard, and couldn't easily be swung over the railing. Those that were, risked tearing their sides out on the hull's rivets; and Lusitania sank much more quickly than Titanic so there just wasn't enough time to get everybody off. Lusitania never received the warning that u-boats had been lurking in the vicinity of the Old Head of Kinsale, Lusitania's customary landfall, or the Captain wouldn't have stopped zig-zagging.

[@yknott9873]

And Empress of Ireland suffered a further design flaw. It was common for coal bunkers to run along the ships' sides, for easier refilling; but additionally, Empress of Ireland's staircases ran across-ship instead of fore-and-aft. So when the ship listed, half of the staircases were vertical and the other half didn't go anywhere fleeing passengers would conceivably want to go. And thanks to penetration of a coal bunker, Empress of Ireland also sank very fast.

[@Zcp105]

The most important factor in the Titanic sinking was the coal fire. And no, I don't mean that the fire weakened the hull and caused it to sink faster- that's a myth. The fire meant that all the coal in that bunker on the starboard side had to be shoveled out and transferred to the port side. Those hundreds of additional tons of coal being moved resulted in Titanic crossing the Atlantic with a one or two degree list to port. In effect, it was a counter balance to the water rushing in from the starboard side after the collision. Forty minutes after the collision, Thomas Andrews calculated the ship would sink within the hour. In his mind, after an hour or so, Titanic would capsize to starboard. He wasn't factoring in the coal fire. Instead, the ship took more than two and a half hours to sink and remained mostly stable until after she split in two. In every other shipwreck, the vessel capsized. Titanic did not, and that was because of the coal fire. My guess is IF the QMII suffered enough damage to sink following a collision, then the odds are that she would capsize and probably sink much quicker.

[@DSGNflorian]

The Titanic was not designed to float with ANY 4 or 5 compartments flooded. The minimum buoyancy reserve was any 2 compartments. The ship was also designed to stay afloat with the forward 4 compartments breached, at least in calm waters, as the bulkheads forward, including the so-called "collision bulkhead" reached several decks higher than the ones in the middle of the hull. Mauretania and Lusitania did NOT have double hull construction, but the arrangement of their coal bunkers along the sides acted, at least in theory, similar to a double hull, provided the coal bunker doors were shut or could be shut in the event of flooding from damage to the sides. Stability would indeed be a serious concern with this layout as the risk of capsizing with several of those bunkers filled was definitely high, especially in rougher seas.

[@olympicnut]

The evidence indicates Titanic did have her engines at full ahead when she hit the berg. It took quite a bit of time to execute any engine orders back then and the engine room crew was not on stand-by at the time. Over the years the testimony of Fourth Officer Boxhall, who was not present on the Bridge when the evasive action orders were given, was taken as gospel. Other testimony indicates there was not time for engine room orders to be carried out either way before the impact. Titanic could stay afloat with 2-4 compartments flooded, depending on the location of the damage. I doubt QM could survive with ANY 5 compartments filled with water. The longitudinal bulkheads on Lusitania/Mauretania were problematic. If more than two flooded, the ships were in serious danger of capsizing. A floodable length curve for QM would be a good starting point. There are several major errors here, so the speculation has little basis.

[@worseorbetter]

Titanic had a 7 to 10 degree list to port as a result of a coal fire in one of the forward, starboard bunkers. About 30 tons of coal had been transferred to the port side in order to access the fire and extinguish it. Shortly flowing the collision with the iceberg that compromised the hull on starboard 10 feet below the waterline. On the centerline of the vessel is the fireman's tunnel that acted as a watertight partition dividing both sides. As seawater rushed into the ship the vessel was balanced back upright as the weight equalized on both port and starboard. This most likely was the causal factor in the plunge type sinking bow first rather than a capsize. A coal fire afforded more time in the end. While Queen Mary has the double hull, if breached she hypothetically may be more susceptible to capsize.
