I’m surprised at how fast this video was made and is and it’s fully animated
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
Me: "Only four and a half minutes long video? Why so short?"
CN: "On the 26th of March, 2024..."
Me: "Wait, what?"
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.
A slideshow of basic sketches would have been good in that timeframe; getting out an animated 4 minute video explanation is legendary.
RIP to the 6 road maintenance workers, and anyone else, who lost their lives when the bridge collapsed.
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.
Damn, you got this video out fast!
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.
For those that don't know, THIS WAS A WELL MAINTAINED BRIDGE!. It wasn't some old rust monster, and wasn't on the " watch list " for poorly maintained bridges.
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...
As an "Air Disasters" aficionado, I've learned that at least 2 problems need to occur for a disaster & you show them here, loss of power at the moment they're passing an intersecting channel which diverts the ship into the support.
Thanks!
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._
Was definitely expecting a about this from you, just not this soon. Amazing jab once again 👍🏻
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.
I'm pleased to see a video from an actual SME. So many people with no understanding of piloting have been rushing out their responses.
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?
What is known so far is. Mayday was called before the 1st power loss.
Emergency all anchor drop was performed between 1st and 2nd power loss.
The cops managed to close the bridge before impact... hence low casualty numbers.
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.
It's happened before. In 1980, the Sunshine Skyway Bridge southbound span collapsed after being struck by a wayward cargo ship. The replacement bridge supports are protected from future collisions by concrete _dolphins_ on either side of the shipping channel.
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.
Maryland here.... that Bridge has been considered a landmark for decades and people would often take pictures with it in the background.
Whoa, that is some fast production! Bravo!
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 😂
I learned about this over breakfast with WTOP (local radio) and wondered if Casual Navigation would have a video on it. This is impressive coverage for so soon after the event. Please keep us informed if you have more to share!
Times like these, I'm glad I have such an eclectic collection of channel subscriptions.
a plum of black smoke usual means that the EDG is tripped on, unfortunately with restore power, full astern and rudder shifting to make emergency stop was not enough due to lack distance to the tower from the vessel which was going 8 knots. dropping the anchor would not help again because the short distance to travel and the speed of the vessel. the observation of + and - pressure known as bank and suction effect is a very good point as to why the vessel swung to starboard, something I didn't think of initially nor has anyone else pointed out in the CZcams video or in the press as subject matter expert. Bravo Zulu "Casual Navigation"
The power went out a second time by the way
@@m0-m0597 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
Bro is quick with it
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😂
Good that you stick to what we DO know at this point. There are already those that are making wild speculations. Some evidence that the ship lost electrical power for a short time (video shows lights going off and then coming back on) but that's about it. Looking forward to you making another video when we know more.
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. 🙄🙄🙄
I have been subscribed to you for a long time and I was waiting for this video. I wasn't expecting it to be so soon. That's insane workmanship. I'm from Baltimore and have been on that bridge millions of times. You explained in that video of the area like you were a local. Good job mate.
Media is now reporting that the vessel did lose power. I hope when the report drops that you revisit this.
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.
That was fast. We're looking forward to a follow-up once more information is released and the causes can be properly examined.
Great job! 👍
I'm so impressed with how quickly this was created. Bravo!
This is so quick that I started to be suspicious that Casual Navigation has somthing to do with this incident ! 🤔🤔🤔🤔
Same mate
Thanks for your efforts to cover this so promptly. As soon as I saw the news report I couldn't wait to hear your thoughts and you haven't disappointed.
Hats off to Casual Navigation!! Still just hours from this tragic incident and yet an episode with explanatory graphics and navigation points already plotted is prepared and explained. Very Impressive. Sort of mutes all of those spouting the ridiculous conspiracy theories.
This channel is a treat. Thank you!
There was a 13 knot wind that pushed it off course as well. Combined with pressure change from the channel off the port side would definitely change its heading. Prayers up!
without doubt a compounding factor, but loss of power, and thus control, will likely be the main cause
I have noticed too on the longer videos of the accident showing more time before the impact that the lights of the ship turned off and on few times so I was also thinking that it is some sort of malfunction on the ship itself.
I can't even imagine the number of casualties if it was during rush hour...
Thank you for the fast and clear explanation of what happened with the limited information available at this moment.
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
The rest of the internet be like, I don't know, therefore aliens
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 😜
A few observations:
1:58 The main masthead navigation light on this type of vessel would be above the bridge, rather than the funnel.
2:00 This was the second of two blackouts (The 1st blackout was at 0124:32 EDT, with power temporarily restored after 61s; the 2nd blackout occurs 125s after the first, as you correctly state, at 0126:33 EDT) - Times are assuming time stamps are correct on the livestream camera.
The first blackout looks like a total blackout. The second blackout appears to show emergency lighting at liferaft and lifeboat stations (near the funnel and accommodation entrances). The navigation lights are also visible during the second blackout.
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.
You were the first channel I thought about when this happened and I was not expecting a video until the investigation was completed!
😅😅😅
Much the same sort of thing happened in Hobart, Tasmania many years ago. The Tasman Bridge which joined the two parts of the city was hit by a ship and the city became dysfunctional during the years it took to replace the collapsed spans.
genuinely amazed you got this video out in less than a day, huge respect!
I heard about this event this morning and immediately thought of this channel. Thank you for your professional videos and unassuming and respectful take on this situation.
Nice work getting this out today. Just a quick note: routes and interstates are distinct types of roads in the US. Referring to it as Interstate 695 or I-695 would not only factually correct but add a crucial detail about the magnitude of this collapse. Only sharing cause I know how fast you had to produce this video, otherwise disregard.
Sir, on your next update of this video you may want to consider using displacement rather than gross tonnage to indicate the mass striking the bridge's structures. As you stated, GRT approximately 100K (95,128T). Her approximate displacement at max draft is approximately 150K tons ( 🔺️=148,974 T), which is 50% more. Respectfully submitted.
Impressed you got this video out so quickly!
I knew you’d make a video on this but I did not expect you to get this out so fast, bro really cooked so hard he managed to, record, edit and animate an entire video hours after the wreck
The complete lack of concrete bumper on the tower for a bridge near a major port like this seems odd to me. I doubt it would help too much but those pillars just look unprotected completely
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
Thank you for putting this together so quickly. The news reports gave a partial plausible explanation, but this filled in the gaps. Obviously we should wait on the NTSB report (likely in 2 years) before forming too strong of an opinion, but this answers some of the confusing parts like why DALI would drift towards the bridge support without power.
As soon as I heard about the incident I was looking forward to the analysis done on this channel, I just didn't expect it to be so quick!
Thank you for making this and covering this! This is one of the better more in-depth breakdowns that I've seen and I've been doing a lot of research on this as well as the ship's owners and insurers
Considering this is out the same day as the incident this is very well measured.
I understand why the bridge fell, engineering wise, I'm just amazed there wasn't more protection for the bridge considering the port.
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.
Only another ship driver can appreciate just how fast everything can go to hell on the bridge of a ship. My first inclination is to wonder why the ship was going so fast prior to passing the Key bridge. I'm going to wait for more information before commenting further.
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.
Been waiting for _the best_ explanation of what happened, thanks for getting this vid out so fast
For Kontext, this ship travelling at 7,5 knots /8,6mph/13,9kmh has about 2,5x the momentum of a fully loaded Airbus A380 travelling at full speed (though lower kinetic energy).
This is pretty much as close to an unstoppable force as you ever get in real life 😂
Amazing production time, bravo.
I saw your video before I heard the news, I was so confused for a moment 😭😭
Ok, to fully animate and post a video this quick after a disaster is genuinely impressive
Thanks for the incredibly fast update on this. You’re amazing.
Looking forward to future updates.
I find it surreal that I’m watching one of your videos about an event that happened, on the day that it happened!
Please do an update video when it becomes known what happend in its entirety. This will fade from the news quickly (as most stuff does).
Hey just wanted to say while you definitely get top marks for getting this out so quick, personally what I like about your videos is the greater depth and explanations than can be found in news media. Obviously you do the best with all the info you can get at this point, but nothing wrong with waiting to deliver a more thorough one either. Cheers!
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.
I don’t know how you have managed to put this together so quickly but it’s excellent. Well done!
Dang that was quick. You gotta time machine or something?
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
FACT🔥 Casual Navigation makes 1 video a month even during wars, hurricanes & famine. When a large cargo ship hits a large bridge, casual navigation turns into instant navigation 💪👏
As you say, we don't know yet. But, based on the limited info it appears there was some sort of propulsion power failure involved. Assuming that to be correct, it raises an issue I've had for a long time that might make for a good video: Why do so many modern ships make do with a single engine and prop? I understand the efficiency there. But the utter lack of redundancy baffles me when we're dealing with massive ships.
I'm thoroughly impressed by the expediency of this video, especially with having it fully animated. Please keep us informed when more information arises
That was quick!
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 ! 🤔🤔🤔🤔
The vid with all the pertinent info came on 2 hrs after the accident. No animation: data was attained by radio and video: every thing was visible on the zoom in.
1. 2 min out the ship lost power, engines were off.
2. Anchor (starboard) was possibly dropped ATT
3. Engine restart, fuel heavy burn.
4. Reverse engine (it's like a long string pulling the ship from the rear: no lateral control.
5. Engines go off .
6. Stern drifting off to the port/left direction of momentum is to the starboard/right.
7. Engine restart and ship strikes pilon.
It is not known if the port anchor was dropped.
Thank you for making this video. This bridge has been a symbol of my home town for more than a generation and this is a devastating loss for our whole region.
Only media on this event I’ll watch. Excellent as always! Thank you very much for making it!
Good analysis. The video shows that the ship did, in fact, lose power before crashing, potentially twice.
According to the ITN and BBC News at 10 she had been tripping shore power breakers all the while in port and her own power ones, just before the collision she suffered another power failure from all the video footage recorded. Was it that the computer systems took time to reboot after the emergency generators kicked in. She put out a Mayday minutes before, enough time to stop traffic and clear the bridge of it.
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.
From what I've heard, after the Dali lost power the crew called for tugs, dropped anchor, and called mayday three times to get the bridge closed. So great work from the crew, there was just nothing they could do to stop that much momentum
Thank you for framing this clearly as "ship destroys bridge" and not misleadingly as "bridge collapses"
0:13 As a native Marylander, the way you pronounced Maryland hurt
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!
Dali's EMPTY weight is 95K tons. Dead weight is 116K tons. Dali carries up to 10K 40 ton containers. Her laden mass was closer to 350K tons.
wrong calculations, total displacement was around 150K (huge anyway)
Why didn't they have a protective barrier around the piers. Most bridges I live around have a barrier island structure around each pier to keep boats from hitting the piers.
You'd have to research whether they were required in 1977 when it was built, or even if required since that time as an upgrade.
Congratulations on the speedy production of this!
3:10 According to Sal at "What is Going on With Shipping?", she was only travelling at 1.5 knots at the time of impact ------- still a disastrous amount of momentum.
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

Thank you for the quick production, and for urging everyone to wait for the facts.
Great video. It's cautious, attempt to provide explanations while reminding everyone that these are conjectures at this point, and factually describe the things we know happened. I wish the internet were more like this;
👍👍👍
I've looked at a lot of other channels regarding this accident and the sheer amount of people who are claiming that they rammed the bridge on purpose and that it's all some kind of government conspiracy is hilarious.😂😂😂
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.
In hindsight, leaving an important and fragile structure that goes over a very important waterway almost completely unprotected from a ship strike may have been a bad call.
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!
Good work getting this out so quickly. Hopefully your concise explanation of what we know so far will help to counter some of the wild speculation some people are making about the collapse.
Woah I saw this on the news earlier and you already have a video out! That was fast :D
I need to understand how can a major harbour like this with a massive important bridge and giant ships operate without TUG boats staying with the ship until it's passed the bridge
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
I love seeing that underwater map, not something you typically see in most maps
This was fast! My first thought when I heard about the crash was that you would eventually put a video out on it, but no idea it would be within a day!
well done getting this out so quickly. also, thank you for the laugh during these trying times because of your pronunciation of "Maryland" hehehehehe
I'm from College Park(ing lot) and this was one of the most outside the Beltway pronunciations I've heard yet.
I live around Baltimore and best believe it’s the only thing people have talked about today. Thank you got covering this. Baltimore will recover 🖤❤️💛🤍
Power failure. Ship banked starboard due to current. Power recovered. Master ordered full astern but this led to starboard drift. Port anchor dropped to correct drift. Rudders lacked water flow to correct course. It wasn't enough.
Hindsight says accelerate and navigate but hindsight is 20-20 and there were dangers to doing that too.
Good it happened at night and not rush hour.
Even if you had all or most of the assets already I give props for animating it all in such a short time from a standing start.
I was waiting excitedly for this, thank you
I love when British people say Maryland
You mean my tin foil hat was on too tight?
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?
Great work! I hope getting something out so fast helps get this video into trending and get more attention to your channel!
Kudos to getting this out so quick. Thoughts go out to all impacted by this tragedy.
Hey cas-nav, I'm a captain and something that seems likely to cause the turn to stbd is when he backed down on his right handed single screw. Not going to say I'm definitely right, but it very much looks that way from the video and marine traffic data
The engineers that built the bridge clearly didn't learn from the Sunshine Skyway incident in 1980. This bridge should have had changes made to it after that, so it was only a matter of time. I hope those who are currently missing are found alive and well.
Saw you on the BBC giving your expertise! Recognised your voice immediately! Glad they got a man who knows his stuff in on the subject! Great work man!
Can I congratulate you on being able to produce such a good video in such a short time frame. Very informative, thank you.
The ship definitely had some problems with the engine and/or electrical system. As we can see it loosing lights at least twice and engine at least once
The only questions are:
- why?
- why did they not have redundancy?
- Capitalism
- Capitalism
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
I really appreciate that you tried to get this video out as soon as possible, and it's impressive that you made it so quickly. But in that haste, it misses some of the (admittedly few) details that we've already learned. I was looking forward to an explainer video from you explaining what happened but figured it would be a few weeks or months away. Honestly, I think I would have preferred to wait and get a detailed video, rather than a quick one put out before much of the circumstances are known.
Thank you for a very sober and respectful "news video".
This is the 6th video I see and the first that did not jump to conclusions based on practically no facts at all - except for the correct name of the Vessel and the bridge !!
At 10pm UT+1 (cph) on the 26st of March Danish news channels reported that there should had been two local pilots onboard and that they had turned on the alarm, due to lose of some kind of power, in time for at least partial limiting the traffic on the bridge..
Thanks for the explanation! I didn't realize how much went into controlling a container vessel especially with the influences from other bodies of water
Why was the ship allowed to pass underneath a bridge without tugboats?
Tug boats are not safe to be near a ship traveling over 5 knots.
For those that don't live in the US, it's pronounced: Merr-il-ænd and six-ninety-five.
Thanks for the helpful video, it’s great to see your take on what is known so far. 🎉
The ship lost engine power, started up the backup diesel generator, but that only gives electrical power. The pilot warned the bridge to stop all traffic heading onto the bridge, turned the rudder and dropped the anchor, but it was too late to avoid a collision.
