How Did A Ship Destroy Baltimore's Key Bridge?

This is so quick that I started to be suspicious that Casual Navigation has somthing to do with this incident ! 🤔🤔🤔🤔

The animation was prepared a week ago. Hhmmmmm…..

@@duran9664bot thinks he crashed and went alright lets make a video lol

He undoubtedly has most of these as generic assets already. Animation doesn't take long on a computer as long as the assets are there.

That's what I said wth

For real. I had to back up 3 times to be sure I heard it right.

Yea it happened today. Why does that shock you? Never seen news the same day?

​@@Lobonova Animations take a while to do, so their shock is understandable.

@@Lobonovabut this isn't a news channel, generally speaking

@@Lobonova Honestly, I saw it on Sal's "What's going on with Shipping" and didn't expect him to be covering it less than 8h after the crash. Super fast coverage.

Thankfully, it happened during the night and not during rush hour or it could have very likely been much worse.

So far it looks like no human error, at least with the crew rather than maintenance.
The crew are probably feeling pretty bad about it though I guess considering though.

It seems the crew did everything they could to avoid the collision. I think it'd be hard to charge anyone cos I don't think there is anyone to blame. It's just one of those things. I mean you radio telling people your gonna crash clear the bridge, throw the anchor to try and avoid the bridge, no power to turn... That's really all your options gone. A ship takes at least 3 seconds to react to any turn you make. Even then it's not guaranteed you'll make it. I personally think this was an unavoidable accident. Everything adds up to everything happening all together and at preciously the wrong time. A minute or two either side of the bridge and it could all be OK or at least not as bad.

You've done a better job than the author of this video lol

@Magikarp-yk7io This channel is 100% correct and was released 3 to 4 hrs after it happened. My info came from press releases, and the videos released a couple of hours after this channel.

Was the bridge closed off?
I heard it was a highway bridge like normal traffic was on there?

When the ship lost power they radio an emergency and first responders were able to close off both sides of the bridge. But there was a maintenance crew that didn’t get off in time. I believe they rescued two of them and 6 are still missing.

Not daytime traffic

My grandpa was a civil engineer and he also designed bridges. Rest In Peace to the victims

@@robinnautica9773 police received the mayday and they shut down traffic literally seconds before it collapsed.

This is so quick that I started to be suspicious that Casual Navigation has somthing to do with this incident ! 🤔🤔🤔🤔

It's probably easy to make since it doesn't really say much, disappointingly brief for a Casual Navigation video. I'd be more interested on a real analysis once more facts come to light. But, since the world is shining a spotlight on his niche, I can't blame him for getting a quick video out, lol.

@@duran9664ur in every reply buddy 😭i think you can take the tin foil hat off lmao

As fast as the bridge collapses after impact. It was gone in less than a minute!
Rip to the people on the bridge deck.

@@duran9664Fake news, and you’re literally in every “wow quick post” comment. Go outside, touch grass, and quit spreading misinformation.

True, but few bridges can deal with a 100.000+ ton freighter ramming into them.
This includes newly build bridges as well.

But there were no dolphins to protect the supports from vessel impact. And this is one of the busiest Ports on the east coast.

Should've mentioned which bridge...
Cuz there's a bridge on the ship too

​@@user-qy1dy1ms9mhahahah I was so confused, thanks

@@user-qy1dy1ms9m there is two now...

Mentour Pilot? 😂

@@Lordrocky24 This kind of information just after the fact is probably more blancolirio or Vasaviation type of content.

If you watch the real videos, the ship doesn't turn to port at all until after it gets power back on for the final time. It then steers hard to port as soon as it gets back underway.

@@ValensiakolWhen you see the lights turn back on, I heard that those would be the auxiliary engines. They would still have to restart the main engines.

There's always at least 2 problems that cause a disaster, because if any 1 problem can cause a disaster, _that lack of redundancy is itself a problem._

100%, I was looking forward to this video in the future. Maybe if the details are spicy enough he can make a more in depth video.

@@josh9289 We already know _why_ the ship started slipping and _why_ it was so easy to hit the bridge. I'm guessing he was more concerned with getting this up than checking out information.

I was not expecting to hear the word “tug” more times in 4 minutes than I’ve ever heard in my life. The tugs were tugging but the tugs couldn’t tug enough.

Tbh UK is several hours ahead of the US, so we woke up to the news about 5-8 hours before you woke up to it. So he had all day to put this together. Not knocking anyone, but timezones definitely helped in this case!

@@georgeprout42we’re 4 hours ahead and nobody warned them is was gunna happen 😔

​@@lachlanchester8142 That's real negligence and shellfishness.😢

That's what she said

@@lachlanchester8142😂

Agreed. How many people don't realize the sheer magnitude of mass this ship has; it's as long as 3 football fields, and has enough containers to load up at _least_ four freight trains. Then the ship itself, which probably weighs more than 1,000 Abrams tanks.
As soon as the ship's engines failed, that was it. The biggest mistake they made in this whole incident was to not have this ship guided through using tugs until it cleared the bridge. But that's not so much to fall to the ship as it is the port authority for not mandating this extra layer of safety.

I was a bit disappointed about the analysis of a video titled "How Did A Ship Destroy Baltimore's Key Bridge?"
Conclusion: "The ship turned to starboard and hit the bridge pylon"
Ah, OK then. I did notice that myself though.

This screams negligence on many levels

@@user-bf8tv8xv4w What conclusions do you think could reasonably be reached within 24 hours of the event?

@TheEDFLegacy how many pool noodles does that equate to?

This is so quick that I started to be suspicious that Casual Navigation has somthing to do with this incident ! 🤔🤔🤔🤔

I mean, if I was him and I saw the news, I'd also be cranking up the computer to try to get in on the story while its hot
It probably wasnt that hard to animate since he already has all the stuff for it

@@duran9664stop replying this on every comment, bot.

Lmfao 😂

Because it's just awfully coincidental that it's just after a new captain who's from Ukraine took control of the ship.
Not even an hour after leaving Port.
AIS shows the initial turn to starboard, followed by a sudden correction to port right before the bridge.
Didn't drop anchor as soon as trouble presented and pointed a bridge.
It's just... Awfully coincidental.

@@alexanderhamilton4258 That is unhelpful insinuation. Please don't.

@@alexanderhamilton4258 This isn't coincidental, it's cherry picking.

⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠@@alexanderhamilton4258
Your implication falls apart at even the most minor of scrutiny.
If it was intentional, why’d they signal for help and get the bridge shut down?
What about the rest of the crew who wasn’t the captain? The captain’s not even the one in charge of steering the ship to begin with.
And why the hell does Ukraine have anything to do with it? The US is an outspoken supporter of the Ukrainian effort.

@@alexanderhamilton4258 Downvote on every wacko conspiracy theory. 🙄🙄🙄

Yes, you're correct and I believe that in the recommendations it was suggest that all bridges in the US need these dolphins to protect the support piers. It looks like every government since the mid 80s just kicked this down the road. After all there is no photo ops on completed dolphins... 🤨

Dolphins were proposed for the key bridge some years back and they were deemed too expensive 🤷

​@budgreen4x4 someone did the wrong math. I'm sure they're less expensive than replacing the whole bridge and shutting down the port for weeks.

​@@tonymouannes
Corporate didn't like to add thing that cost more money if the accident didn't happens 2 times per day.

@@tonymouannes The ship had about 750 Million Joules of kinetic energy at impact. Your options for stopping that aren’t cheap. Pick what you want but you’re going to need several thousand tons of it.

The power went out a second time by the way

@@wireless-earbuds-brain-tumor hmmm, the plot thinkings

IF there was a full astern order could prop walk also be a potential reason for the turn to starboard?

@@nicholaswhitfield9341 absolutely

This is so quick that I started to be suspicious that Casual Navigation has somthing to do with this incident ! 🤔🤔🤔🤔

Same mate

It was known the ship lost power 11 hours ago; 9 hours before he uploaded. He should have known.

@@grondherothese videos take time to animate, edit, and upload. Probably by the time the script was wrote and animated they still didn’t know

@@jasonmurawski5877 Then he should have waited, especially if it takes 9 hours. The information has been up for half a day.

​@@grondheromisinformation started minutes after impact. It's more important to remind people to wait than to come up with ideas

@@PianoKwanMan I know, that's what I was referring to.

So far I've mostly seen 'the crew are totally responsible' and 'intended attack from evil terrorists'. I imagine the aliens and inside jobs claims are just around the corner.

Definitely aliens 😟or just drunk Norwegians 😜

without doubt a compounding factor, but loss of power, and thus control, will likely be the main cause

I wonder if he was too far along animating this to incorporate details from those live feeds. I'm wonder when those first became available. What is Going on With Shipping had a video several hours before this went live and seemed to have those extra details. N39w6aQFKSQ

A Harbor Pilot would have been at the helm, could be unfamiliarity with the specific procedure to deal with a power failure and re-start?? Is there a bow thruster?? good job dropping anchor. Did they bother to blast the horn ?? The 6 road workers woulda had 2 minutes to drive off the bridge, considering Cops were able to shut the road down.

@@peterdarr383 Hard to say. Does the horn require power? And would the road workers even have known what the horn meant or be able to hear it for their own machinery going?
We should probably be thankful it happened at a time with very low traffic and not during rush hour.

@@nt78stonewobbleThey stopped traffic, which means they had the time to have a patrol car sweep the bridge, and announce over PA to get the F off the bridge NOW

@@peterdarr383 That doesn't seem to have been the case.

On the Swedish news yesterday evening they said that the ship had been signalling(don’t remember if it was radio or something else) that they had an electrical problem so the lights acting like that seems to make that probable

The Ship had completely lost power. The crew managed to bring it back on and it lost power for a second and final tjme

😅😅😅

They're there, they're just angled to protect from a direct approach and don't seem adequate. MV Dali slipped in at just the right angle to get past the bumper.

Depending on how they're structured, dolphins (the bumpers you're referring to) can deflect the energy sufficiently, but you're right that others have failed. We'll also likely see more isolation so a cascade collapse is less likely. I think a lot of lessons learned from the Sunshine Skyway Bridge collapse are going to get applied here.

I have serious doubts about whether or not those pillar dolphins/buffers/deflectors/pillar protectors/ICC bars 😂 (trucker joke) would actually work when faced with a 100,000 ton hunk of steel, regardless of the ship's speed.🤔

The problem is that if you need to let very large ships pass through you can't have to many dolphins as they would block the ships getting through.

@@DC9Douglasyou’re totally right and imo no bridge ever made could survive this. People saying bridges should be able to tank a container ship are basically calling for a dam

Minimum maneuvering speed?

@@Knirin You are referring to the ship's speed through water vice speed over ground. Minimum Maneuvering Speed varies from ship to ship and is based on a laundry list of variables.

sure was, just like that comment.

Says your mom.

shut up dad you're drunk@@benderbendingrofriguez3300

This is so quick that I started to be suspicious that Casual Navigation has somthing to do with this incident ! 🤔🤔🤔🤔

For someone who knows nothing about engineering it's hard for me to grasp how a ship, moving at apparently slow speed, can have such a profound impact

Momentum is Mass*Velocity. A really heavy object moving even slowly still has an absolutely massive amount of momentum.

​@@davidbond8139 as @andrewcooper7256 says the ship had a lot of momentum.
Container ships weigh a lot, like a lot lot, so getting them to move needs a lot of power, which means a lot of power needs to go somewhere when you want to stop.
In this case that power went in to the bridge structure in a place it wasn't meant to. Bridges like this are designed to support themselves, take a part out and it all fails.

@@davidbond8139 Force = Mass * Acceleration. Force generated can still be very high with a small acceleration if mass is large (as is the case here)

The bridge was built before any of these bridge disasters had happened. It was never upgraded.

hahaha

This is so quick that I started to be suspicious that Casual Navigation has somthing to do with this incident ! 🤔🤔🤔🤔

Causal Navigation were you the one driving?

Hey my fellow railfan

wrong calculations, total displacement was around 150K (huge anyway)

There is a surprising amount of disinformation about this event out already. Even a video like this with limited info is helpful in dispeling some of it. I do hope he makes a more detailed video about it when more info is available though.

The important systems aren't computer-controlled. It takes time after restarting a diesel engine to get the ship ready to get up speed - the shafts are MASSIVE things and rotational inertia is not good for starting a massive thing rotating.

How should you say it?

@@FWtravelsLike the name “Marilyn” but with a D on the end

@@FWtravels the pronunciation would be closer to “mare land”

Okay 'hon'. Hope you are from Ballmer.

Yeah. I'm pretty sure we deserve it for the way we pronounce British place names though!

That’s not what I took from Sal’s video breakdown. He had the ship having slowed to about 7.6 kts just before impact and said the 1.5 kts showing after impact was an artifact of issues with the GPS fed through AIS transponders.

Ah! Thanks. That makes more sense than a rapid deceleration. Horrifying, but at least this mishap didn't strike at rush hour.@@MotoNomad350

​@@isekaiexpress9450And the captain.

@@alexanderhamilton4258The entire ship's complement was Indian at the time of the collision, numbnuts. Except for the channel pilot, who was an American.

@@alexanderhamilton4258 No. The crew are Indian. There is disinformation being spread by a large country in the east.

I didn't even realize people were claiming that... I guess it's true, the internet is an amazing place 😂.

Ikr. Maybe they are true but the fact that captain an the crew warmed the construction worker who in turn stopped the traffic into the bridge busts the Idea. Plus it. Can be easily verified. The two pilots were local.

@@user-cr6qv1bn2u It wasn't the construction workers who stopped traffic. It was transit cops who were enforcing lane closures and speed restrictions _because_ of the ongoing construction.
Those poor construction workers never received a warning. How would the captain of the ship even know about them or contact them anyway? Those radios the construction crews have aren't for marine traffic.

As was not using tugs until the ship was clear from the harbor.

It's not hindsight. it's common sense. Many bridges do have Dolphins around them. They do take up space but that is a small price to pay for what can happen. I'm sure it will come up in the investigation.

it does hae two dolphins per side , the ship missed the dolphin@@johanjacobs9240

There were dolphins at the bases of both towers.
Also, once a ship is at 4 knots or better, as stated in this video, tugs need to disengage from the ship to avoid being swamped or sunk. A
ship needs to go at a fair speed (or “have way”) to be able to steer.

@@MrsRubens The dolphins around that bridge was not effective to stop all that mass. In fact there were none!

You're saying communism would do any better? Because if Chernobyl taught you anything, commies love putting loyalty to the party above actual merit or competence@@katherineberger6329

In the last inspection the ship had a problem with the electronics

Or not tight enough?

Yes, accidents happen. Mechanical failures happen. Out of all the crazy stuff that happens in the world, if you think this is the conspiracy then you're regarded.

@@_Super_Hans_. Regarded?🤔

I unfortunately can speak from experience of being in charge of a vessel that suddenly becomes not under command.
It's a crappy ride and a terrible feeling knowing there's next to nothing you can do to stop the events which have been set in motion.

@@vb305 Kinda like losing control of a car on ice but way worse?

Tug boats are not safe to be near a ship traveling over 5 knots.

Seemed to work out fine for the past ~50 years.

@@randymann2082 Yes, they do.......look at other information sources...big mistake for the tugs to pull back...

Yup, what you said is right.

As he stated in the video, the risk of capsizing the tugs is too great for them to stay with a ship that is speeding up.

@@pneumarian There's the problem, giant ships speeding in a harbour, keep it at 4kn with tugs assisting, honestly wake up

You can also call it the Key Bridge. People around here call it that all the time, it’s just the shorthand name for it.

Most people just called it the Key Bridge though. As an aside, the bridge was built less than 100 yards from where Key's ship was moored during the Battle of Baltimore. There's an buoy with the American flag painted on it marking the location.

@@BigBuck3ts I don't doubt that, but what a local knows and what the rest of the world knows need to be balanced.
The problem here is the word "Key" itself. Since Key could refer to Francis Scott Key, or being the integral bridge of Baltimore (not denying it's importance, it's absolutely key/integral to traffic flow in the city). There's also someone potentially mishearing "The Key bridge" as "a key bridge" which for a city like Baltimore with several bridges is a potentially confusing statement.
It's better to be clear than potentially confusing in my opinion.

@@PendragonDaGreat Acting as an armchair editor, try rewriting your OP without the "not". e.g. ...that the "Key Bridge" is officially the "Francis Scott Key Bridge"...
