- Jeff Ostoff shows you the latest updates on the engineering disaster aftermath of the MV Dali ship striking the Francis Scott Key Bridge causing the bridge collapse in Baltimore, Md. on the Patapsco River. The video also shows how they started to remove the Key Bridge collapsed truss and roadway debris off the deck of the MV Dali ship. They hope to have the MV Dali refloated by May 10, 2024. They closed this limited access channel on April 29, 2024, after the first ships to pass through the new limited access channel, a deepwater 300 ft wide, and a 35-foot deep access channel for larger ships, the first time since the MV Dali collided with the Francis Scott Key Bridge in Baltimore, MD on March 26, 2024. You'll see progress so far in this Baltimore bridge collapse.

They barge the bridge collapsed bridge debris to the new 10-acre laydown yard used by the U.S. Army Corps of Engineers to process wreckage from the Francis Scott Key Bridge site. An estimated 50,000 tons of concrete and steel collapsed; once removed, the wreckage is sorted and transported two miles away by barge to Sparrows Point. Debris and wreckage removal is ongoing in support of a top priority to safely and efficiently open the Fort McHenry channel. - แนวปฏิบัติและการใช้ชีวิต

They're gonna have a hard time finding a crane able to lift that flat section that wedged in there.
Do you think Dali is repairable?
Did the respoders recover all of the workers? I can't remember.
Last I recall two were still missing.
@@patricialee4611absolutely. Far worse damage to ships has been repaired.
The insurer will likely claim full loss, then sell her to the highest bidder.
It will likely be repaired with cheap labor in a developing country.
@@nunyabizness9216 I’m not 100% positive but I think there are still 2 not found.
Dunno if anyone was curious about this and hadn’t seen any comments/questions. Anyone who is curious about the open top orange (red?) boxes on the roadway with all the small almost round looking objects scattered around in the pavement, here’s what they are. The boxes (obviously) held the scattered objects and are usually stowed in the bow, amidship, and stern areas. They are called knuckle boxes. They hold knuckles which are the roundish looking objects scattered around. Knuckles are placed into the bottom corner post holes at all 4 corners of each container. They lock into the top corner posts of the container below it (or
The deck for the bottom container) thereby locking the whole stack together. The knuckle boxes are offloaded at every discharge terminal and as the container comes off, longshoremen remove the knuckles and throw them into the knuckle box. Before a container is loaded the longshoremen place the knuckles into the corner post. The boxes are labeled with the ship name because they are assigned to the specific ship. All the trivial info you probably never really cared about and regret the time you wasted reading this!
Good info ! Thanks!
Thanks for the info. I did wonder…and now I know. Information that I will probably never use, time I’ll never get back 🤣 but I learnt a new word, “longshoreman”.
Commenting from Western Australia. 🇦🇺
Thanks! I was wondering what those were about. Thanks again.
Mystery solved, thanks.
Great information, thank you.
Jeff, port-left, starboard-right
Jeff, as you face forward on a vessel, port is to your left, and starboard is to your right. So when you're facing the ship from out in front of the bow, it's reversed, with port on your right and starboard on your left. This is so that no matter which way you're facing on a vessel, you can always specify the side without the confusion of "Left" and "Right"
I was going to mention that.
Oh, my other left!
Both port and left have 4 letters.🤪🤪
@@mariek2070 And Port side has red lights just like port Wine (red)
I live a few miles from the bridge and I couldn’t count how many times I’ve driven over that bridge. Seeing the roadway on the ship…. I can picture it in my mind like I’m driving right over it. It’s crazy to me!
I follow all of your videos.
Thank you for your continued coverage.
How is the traffic getting around without the bridge?
@@billrehm3590 Pretty sure the I-95 Tunnel.
Right? Only drove it a few times, but still, just wild to see the road just draped across the ship!
@@billrehm3590for cars, probably the tunnels, for hazmat, they probably have to go all the way around the Baltimore beltway the inland way. They may also reroute to 81 if they are going farther.
@@billrehm3590 luckily my commute to and from work is no longer in that direction. I used to take one of the tunnels and would use the bridge as a back up for tunnel closures or bad traffic. I had a cashier at my grocery store have to quit because she used the bridge and what was 20 minutes became over an hour commute. My youngest son lost an employee at his job for the same reason. My oldest son drives hazmat vehicles and his commute time is hugely affected but he’s on the clock so it’s he deals with it. But his company probably isn’t happy with the loss of productive work hours. Locally, it is DEFINITELY felt.
"The Craw??"
"Not the Craw! THE CRAW!!"
I'll never get that 'Get Smart' moment out of my head.
Me too. I remember it well.
Let's not forget "The Cones of Silence". Lol
If only the Dali had missed it (the bridge) by that much.
It’s astounding seeing the vastness of the bridge sitting on the ship. I never imagined that i’d be seeing images of the actual roadway of a bridge that I had driven over. Get such a sinking feeling seeing it like that. It’s still unbelievable that this happened.
I live 5 miles from the collapse site and can’t count how many times my family traveled over that bridge.
Great recap of bridge wreck removal work today!
Thanks William!
Thanks Jeff for keeping us informed of what's going on. God Bless To All.
Your best update yet. AWESOME footage
The schedule slides that Sal showed last week mentioned that the removal of the girders on the Dali would involve explosives. Best way to avoid surprises and minimize uncertainty in how it comes apart.
Probably FLSC.
But it causes shrapnel to launch. It can go pretty far. They used it on a power plant in California. A guy that came to watch it was standing about 2,000 feet away and got hit and it cut his leg off.
@@jimnalgrin3515 That's bad rigging. There should be a box of sand wrapped around every large charge to keep that from happening. Cutting charges shouldn't be big enough to make the pieces they're cutting it into go very far. They want it all to drop straight down or tip over predictably. The safety zone for this will be 99% water and the rest will be really easy to clear in any case. That part of demolition is SOP no matter the situation. See @TheLoizeauxGroupLLC channel for tons of examples of how to do it right.
Thank you Jeff for posting these incredible pictures and video clips. For those of us who traversed this bridge daily, it’s bittersweet to see the quite large bridge looking so mangled. Obviously the loss of life is the worst part of everything. Many memories of people roaring past on the two lanes each way bridge. To see those dividers still standing was surreal.
You will be amazed when they finally put properly positioned "Shape Charges " on the remaining portion of the 5K tons of bridge . They will take a wedge out of it and pull the remainder off the deck with the top rails of the bridge and with a delayed charge cut it into manageable pieces as it jumps deck.
I can't wait!
Sounds impressive! I'm almost on the edge of my seat now, waiting to see this!!! 😃
they'll probably use nano-thermite, like they used taking down the twin towers (and WTC7)
I can't help be recall at the beginning many people were saying "you can't blow it up, that would kill everyone and scatter debris all over." LOL
@@frotobaggins7169 I'm inclined to agree with you, but obviously neither of us are trained in the use of explosives. Obviously the demolition teams have calculated how much, and what type of explosives are needed to break up the steel work without putting lives at risk.
Very well narrated and the recap gave everyone some very amazing perspectives of the status of the salvage operation and the enormous scale of the equipment required to move the project forward in a safe and efficient manner . Congratulations are in order for the operators and the seamless manner in which each phase of the endeavor is being carried out.
From 00:45 to 1.20 The piece was removed from the starboard not the port side. Starboard is right as viewed from the bridge and port is the left side.
Nobody really gives a damn about that....jeeze
I think you have confused port and starboard. The port side of the bow is on the left, not the right, when looking forward towards the bow.
Came here to say the same thing. I used to teach boating safety and the rules of the road. It's important to know the difference, especially if you are on the water.
@samanthafordyce5795 Yes. Even most avgeeks know which sides are port and starboard -not counting dyslexia-
Weeks was on the starboard side, not the port side at 0:54 and 2:17. Port = Left, Starboard = Right.
Big deal. Who even cares?
Thank you so much, Jeff for making these videos and sharing them with us. I'm on the west coast but I am riveted by the progress and the enormity of this project. I hope everyone stays safe ... so far so good.👍🇺🇸😎
Thanks for another great video Jeff! I also like Minorcan Mullet’s channel. I live about 5 miles from the collapse site so seeing all the close up pictures really hits home.
The sheer size of the truss section and the roadway that literally just plopped itself on the bow is something else. Still can’t wrap my head around it. Unified Command is doing a fantastic job with this massive task of cleaning up the debris. Please keep the videos coming! I look forward to seeing them 😊
I hope they record and air the setting off of the cutting charges.
Yes, I want to see the drone view video of it
Good stuff! I enjoyed this one. Looking at the pictures on the Dali I'm amazed how strong those twist locks that join the corners of the stacked containers are. The containers are twisted and torn but those twist locks that hold them together didn't yield.
Thanks Jeff. We're sort of lucky to see such a massive, almost ad-hoc, Mechano operation.⚓
Just a quick note. The port side is the left side, and the starboard side is the right side.
Although the MM is broadcasting live, your videos and still pictures tell almost more of the story than the live shot. So enjoy your posts and comments on the ongoing disaster in Baltimore, from a great grandma in Northern California!
Oh goody! Congress is on the scene! Everything will be smooth sailing now!
Great pictures & video Jeff I enjoy watching as cleanup progresses. That is some massive trusses.
Another way to remember it as we learned in Navy boot camp, port and left are fewer letters, right and starboard are more. 40+ years later I haven't forgotten.
Ya - that's the way I keep it straight.
Left side of ship is Port , right side of ship is starboard. Get your descriptions corrected. US Navy
Veteran 70 -75.
Yes, sailor here, I cringed every time he crossed them up!
😂😂. you must be the bully kind of guy . Be nice. Be kind. Don't be an A.Hole
Mistakes are always made. Jeff's trying his best. Be grateful. Be nice.
@@aaronciviris so a good learning experience, advice for anyone doing nautical videos: brush up on the terms first.
Thanks for joining our chat from Baltimore. It was a real honor!!
@10:06 - That shot...that is how you pre-weaken a truss for placing of the copper-coated shaped charges. Anyone who has watched demolition recognizes this. The charges are strapped on the inside and outside of the outer portion of the beam leaving a clean cut and ample separation room.
Hats off to the rigors and the longshoremen
That is definitely a technical lift
There're ironworkers. longshoremen unload ships
It would be interesting to hear 1st hand accounts from some of the seaman on the Dali what it felt like inside the ship when the bridge came crashing down on her. Having a highway and tons of steel come crashing down from that height had to be one hell of jolt !
Give it about a year or so first hand account the works on the Dali on what really happened that night
@@rogerstlaurent8704 bet that was one hell of a pucker factor for those on board 😨
@@rickymeadows5176 They are still puckering and saying OH S$%T OH S%#T in their sleep So next time you thought you had a bad day at work think about the crew on the Ship easy 5 to 10 billion in damages and the owners who own the cargo ship must be playing russian roulette everyday hoping it will end early
Great video Jeff, really brings the massiveness of this disaster !!
Great Close-ups. Thank you Jeff & all
Thanks for keeping the word up to date on Dali. 😄👍
10:27 That's the USCG Cutter James Rankin 555. I've been on the sister ship USCG Cutter Aspen 208.
I hear they are going to use precision detonation charges to collapse the stressed parts of the trusses. I assumed they would. Smart/Safe move for all parties involved with the demolition phase.
Thanks for making these videos for us engineer minded folk.
Thank you for the updates. So interesting.
TYVM for these amazing views. It does show the enormity of it all.
I have to commend this Governor! He has done a tremendous job throughout this whole tragedy!
Thank you for the update and footage.
Amazing video, the pictures are WOW SO CLEAR
Thanks for sharing these fantastic pictures and the Gov's presentation about how things are being done. Great work.
Looking at the size of a container ship like Dali: “Just because we can do something doesn’t mean we should.”
Yeah, but Maersk and evergreen keep building more bigger ships. Dunno when it is going to stop, this madness and greed. All safety precautions are out of the door. ONLY MONEY is the motto. Blind fools. What a mess when something goes wrong......?
Cannot believe it.........?!
The Dali is not that big.
The Baltimore Harbour can't handle truly large ships.
The main channel only has a depth of 35 ft.
There are ports on the East coast of North America withh 66 foot working depths.
@@weldonyoung1013 The main channel has 50 ft (unless blocked after an accident).
But you're right - the Dali isn't *that* big. There are quite a few bigger ships out there, especially e.g. large bulk carriers.
@@realulli , yes I stand corrected.
Thanks for doing such a great job documenting this repair.
Thanks for the rec of the "MinorcanMullet" channel. Great info! 👍🏼
Those close-up views of the containers and the bow are priceless . .
My company is currently there cutting the bridge with hydraulic diamond wire cutting tool
I thought they must be using wire or chain cutting in the areas where things are likely to move when they are cut. To dangerous to have divers cutting it.
@tiredoldmechanic1791 Correct is a diamond bead infused wire , we use these tools in the oil and gas industry on land and and in the gulf of mexico with divers or no divers to remove platforms or pipelines and we also use them for bridge removals
Jeff, best video I've seen so far!!!! The closeup shots are great!!!!
Great coverage. Thanks
Thanks Jeff for this latest update!
Best view and great video so far that I have seen about this wreckage. 👍
Thanks cor that Jeff,really good views of the size of some of that steel work.Thanks.
I cant believe i used to drive on that road on a regular basis and now its laying on the boat😮 just crazy looking at it.
The sounds on impact must have been horrific. Great footage. Thx
Like a million beer cans being crushed all at one time
Thanks for the cool pics.
"Gus the truss crusher". 😉 Amazing clean-up.👍
Merci! Pour le partage, de ses travaux! Pour ses images!!❤❤
Brilliant coverage Jeff I am glued to your coverage of the baltimore bridge collapse from Duncan on the other side of the pond
Awesome video Brother, thanks for the update!
Thank you, Jeff. Great descriptions, I am a retired, mechanical engineer i really appreciate your enthusiasm.
Watching from New Zealand! Your videos are really interesting and way more informative than what I see /hear on the news. The Claw is the perfect name for that machine! Many thanks🙂
Bravo on the amazing work that has been done so far! Hopefully I can head to Ft McHenry tomorrow to see the progress in person.
Excellent video ! Bravo ! Thank-you.
They should sell samples of the bridge truss as a way to raise funds.
That would be cool
Brilliant idea . I am sure someone will already be musing this idea .
Nice idea, but they most likely won't because six people died there and the authorities wouldn't want to be seen as profiting off of misery.
Thank you very much for this in-depth video. This video makes so easy to understand the process of removing the crumbled bridge of the ship. Very clear voice explaining the procedure. Thanks to all volunteer and professional people without them, this project will be next to impossible. May they recover the last man and bring closure to those families.👏👏👏👏👏👏👏👏👏🍺🍺🍺🍺🇺🇸🇺🇸🇺🇸☮️
Great video. Nice to see the close up shots. Thank for making this.
We used to use these precision explosive cut techniques when I was in the Navy. Went to school on it back in 1972 at Indian Head base. We called them shape charges.
Outstanding report 👍
❤ love your videos keep them coming once again double thumbs up keep up the good work awesome job
Awesome video!!! couldnt have been better!!! tq.
That Dali sign should end up in a Baltimore museum..
Small correction. At 7:34, please note the truss section is hanging on the PORT side of the ship (left side for the landlubbers) 😉
I guess its any Port in a storm for some people...lol...
Thanks Jeff great coverage. Well done from a long-term member of the Minorcan navy.
Thanks So Much for sharing this Jeff truly Amazing like you said the Damage and Enormity of everything
Thanks for the great shots really scarey up close like that. Amazing photos. Tfs
Kudos' to you and all who set this video up..very professional and .informative..keep up the good work..the working team deserves a lot of credit also..they can't be lauded enough!
Thanks for sharing!!
Great reporting
Thanks for sharing.
Great update!
Best video yet!
Thanks Finn!
2:50 No the concrete pillar is sheared here! The rest of the concrete top is sitting on the ship to the right of picture
Great reporting sir. Thanks for bringing me up to speed. Liked n subscribed
Wow this was incredible,,,,thanks!
For people who don't know the right side is not port, it's starboard, or what use to be steer board side because the steering board was on the right side of the boat.
And the other side Port because it was next to the warf
Great update, great hair. Keep up the good work.
Jeff: never before seen shots from Dali's bridge...
Me: which one? She seems to have two right now.
Thank you, keep working.
A fascinating video of the work to clear the bridge remains and free the Dali.
Fantastic show 👍🏻😎
This is good stuff..you rock
Nice close up views. Thanks. - Todd in Rochester NY.
Thank you!
There are several comments about port & starboard, what got my attention was that the bridge pier crashed into the ship, I don’t think so that pier was stationary, the ship plowed into it, the pier was there 1st.
Awesome Video, great photos of the damage sustained by Dali & bridge,
don't know for sure, but there saying they found the 5th workman from the bridge
that night, & still looking for one more workman
Love the “claw”. Amazing how crushed those containers are!
Great comments, thanks!
The claws, I like that « name ».
Nice report
Nice work jeff 👍👍👍
Yes I agree keep calling it the claw love your videos keep them coming
Great job Jeff!
