How the Key Bridge crash happened 

i bet he had a nice beer once he got off shift

Well here’s goes another 15 years cap of building another bridge 🙄

An allision is when a mobile vessel hits a stationary object.

My thoughts exactly 😅

Looks like whoever wrote the headline had a stroke.

I learned a word today. It wasnt a typo designed to farm rage comments! Or maybe it conveniently does both! Either way I learned an allision is to strike or dash against a stationary object. *Neat!*

@@corneliusrupert7354😂😂😂😂

Yep, we have google too!

Look like history repeating itself again 😬 😏

Fenders would certainly help. But with the weight and momentum of the ship. It still could have taken out the bridge. Though at least there would have been a better chance of stopping such a terrible event from happening

Yep. And no mention of why there were no requirements to have at least two tugboats attached to any large ship during its passage near the bridge.

yep u got it!!!!!!!!!!!!!!!!!!!!!! ONE person with a brain or make it two Mayday Mayday USA needs help!

He didn't have to mention it after he said there is no build that would have been able to sustain that impact.

Bulgaria

Ukraine

People died

In the white house eating ice cream.

It was a diesel generator at full throttle....hence the Black smoke.

At this time of moment I just feel bad for those towns folks. They have to wait another 15 years into the future, to build up a new bridge

@@problactive285looks like it could have been a fuel supply issue as the smoke cut out and the generators supply power to the boat and the engines the ship more than likely has multiple fuel holdings and depending on their setup could of burned whichever one they were running off of dry before transferring of fuel happened or valves were shifted to change supply tanks

Allision is a real word. Meaning to strike or brush up upon. Google exists, yknow.

I learned this word today, thinking it was a purposeful typo to farm engagement lmao

@vaqal3140 Oh, you misunderstood my quotes. But I'm glad to see genuine intelligence on here. Kudos.

lol well that’s the first time I’ve ever heard that term.

I just got schooled

Learned something new today! Thank you!

Google is a great resource

Yeah, I remember it was a very uncomfortable situation for the crew of the Evergreen when it got stuck in the Suez Canal. I don't think they were allowed to disembark for quite some time.

Vernacular? What's that😊

It had already been put underway by that point. The tugs are for initial port movement in an out.

Or just educated.

@alexadao8852 Derpa derpa

There are other videos that show them. do a search

There are at least four. Look to the right, and you'll see headlights. Edit to say: I looked like vehicles, but the report I read was they'd stopped traffic in time, and it was only roas crew left on the bridge.

​@@bwabwa8810those were construction vehicles. It appears the bridge's two approaches were closed to traffic shortly before the collision thanks to the Dali's mayday call (yay, they did one thing right), so the deaths were limited to the construction workers fixing potholes.

The ship suffered a catastrophic power failure, which killed the steering. Power came back on, they were able to reverse the engine really hard, which unfortunately pulled the ship to starboard. The black smoke is from the reversed engine. They tried to slow down, only to be pulled in the worst direction right into the bridge pillar. The port anchor was dropped while power was out, but it didn't help.

The rudder is stuck in its last position after a power failure.

@@CricketsBay​​⁠even if it was wouldn’t it be stuck straight? I was on several cruise ships that went under bridges and they never approached the bridge at an angle. It was always straight on underneath in the middle of the span.

it had already been put underway by that point. The tugs are for initial port movement in an out.

Yes, where were requirements to have at least two tugboats attached to any large ship during its passage near the bridge.

@@2Truth4Liberty uh, excuse me, that's like an extra $5k. have you thought of the shareholders? sheesh.

@@djentlegiant739 The boat owners pay for tug service, not the State. The State just enacts regulation requiring it.of shipping companies. As far as shareholder in boat ownership, that is part of doing business.

That's what I said

Too soon for jokes

Yes, another. This is the cargo ship Dali, which had 2 previous accidents.

As stated in the video, the ship was not under power from the point where its lights went out onwards. There's been a good video put together by What's Going On In Shipping on the play-by-play of what happened, but I'll summarize. When the Dali lost power, it lost the ability to maintain its course against other elements acting on it. The main ones in Baltimore Harbor are currents and wind -- currents wouldn't have been a huge factor here, but the wind _was._ A ship that large, loaded up with containers, has a massive amount of surface area for the wind to act on, and it was pushed by fractional degrees over and out of the ship channel. The reason it looks like the thing turned hard right is because this footage of the approach has been chopped up for the sake of fitting into a two minute news broadcast. Based on the GPS ship positioning data, the actual approach of the ship took quite a few minutes and its turn was more gradual than it looks here. However, a ship that large can't bleed momentum fast enough to come to a stop before reaching the bridge, and being pushed over by the wind didn't actually slow it down enough. It was only moving at about two MPH when it hit the bridge, but a fully loaded ship like that weighs two hundred thousand tons -- probably more than the entire truss span weighed. Any amount of motion was putting force on the bridge it couldn't withstand.

Did they seriously have no requirement to have at least two tugboats attached to any large ship during its passage near the bridge?

I'm more worried about the people that were on that bridge..

wow, me too. trippy.

Omg, they lost power. If you would watch maybe you could learn something. Don't just pause the video and comment.

It is. And it's been in 2 accidents previously.

So, admittedly, I am NOT a structural engineer. But based on the huge amount of information that's been poured out there already that I've been taking in, the FSK Bridge was a _continuous_ span truss bridge, meaning there was no left and right span per se -- the entire central truss was effectively one big arch. And if you look at about the middle of the bridge at the same moment, you can see a similar kink in the deck there. So based on my own more basic knowledge of engineering and that information, you get something that goes like this. When the support of the left (south) pillar is removed, the area directly held up by the pillar immediately drops, but the parts attached to the right (north) pillar and the concrete approach on the left side are still in place and exert force for a fraction of a second longer to try and hold their parts up. So the big arch buckles roughly equidistant between the middle and those remaining points of support -- both the "left span" and the "center span" roughly snap in half. The right side of the center span takes moments longer because it's got more distance to fall. That part of the bridge then fully topples, but because the whole thing is one giant arch, the right (north) portion is now grossly unbalanced, having had the weight of the rest of it holding it down towards the center. With that weight now gone as the "center span" tears off, it shifts suddenly and massively to the point where the right truss span connects with the concrete approach on the right side, like how if you take your hand off an unbalanced seesaw it'll slam down away from you. That rips the right truss span off the concrete approach down into the water, leaving the part directly above the right pillar as the last to go. Now, as stated before, I am NOT an expert in the field, I'm basically a layman. I also have no doubt the NTSB is going to be thoroughly going over this in minute detail. But based on what I do know, I don't think there was a design problem specifically with the left span. Rather, it's that the design fools you into thinking there IS a left span, when in fact it's effectively all one giant span, carefully balanced on four points of support.

@@InchonDM yeah I agree its why it didnt make sense and I know its a continous span I was just using the support point as a reference point thats all. I wasnt being literal sorry if there was confusion there. Like I said the center did not fold, the left side did... why? it clearly falls way ahead of the rest of it. why did not the support point go first is all I am questioning. Again I def plan on watching what the NTSB simulations will show. I only brought this up because when I talked to my brother who is a structural engineer said that it looked odd also. At least Im not like some of these people crying foul about the supposed 'explosions' on top of the bridge due to the electrical aircraft anti-collision light system arcing out as it was ripped apart.

@@CinncinnatusAnd this welter of people who insist that the ship was deliberately aimed at the support pier, because bad things can't just happen, apparently. Hopefully I didn't come across as lumping you in with them.

Look it up dude. Why would you comment when you can easily look it up?

Yes! Did they seriously have no requirement to have at least two tugboats attached to any large ship during its passage near the bridge?

@alexadao8852 up here the tugs guide em in all the way with a pilot ship too.

A ship that lost power.....

@@wgooetrik I mean everything in general

I mean, did they seriously have no requirement to have at least two tugboats attached to any large ship during its passage near the bridge?

CBS is correct. When an accident involves a marine vessel, it is referred to as an 'allision' instead of a 'collision' (don't ask me why).

yep

An allision occurs when a moving object (such as a vessel) collides with a stationary object (such as a bridge fender).

You should learn how to spell whole. Were you the captain on this ship? So what conspiracy theories do you have?

@@wgooetrik 👀👀👀👀🙊🙈🙉

The ship was leaving the port.

Yes. Did they seriously have no requirement to have at least two tugboats attached to any large ship during its passage near the bridge?

@@2Truth4Liberty Tug boats are meant to guide ships into and out of docking positions. They cannot control a ship that size doing 8 knots while leaving the port.

@@id10t98 You limit speed and tug requirements by law. And then tugs are required - unless the boat owner wants to face huge fines.

No, it broke like it was hit by a massive freight liner carrying thousands of containers. Bridges are not held up by magic; if a giant mass hits them, they tend to fail catastrophically. Take off the tin foil hat the sun is awsome.

They won't because it is the correct term

itz ok, we dont read too good nohow

They used the correct word and spelled it correctly.

@andreww2925 well, looks like I learned something today.

I absolutely stand corrected. Learned a lil something today! 🤘

He does know more about manufacturing than anyone on earth. Just ask him and he will tell you.

A guy named Salvador owns the ship. Rumor is he's a hipster/artist type.

Here comes the conspiracy theories.

read the comments before commenting. Because I just learned that an allision is a maritime term meaning when a moving vessel hits a non moving object.....like a ship ramming into a bridge.
