MORE Video 4K: Moving Dali Ship Key Bridge Collapse Site 

I just love the music, and of course the video, but can't place the music! Sounds like Lord of the Rings but I am pretty sure it's not! It sounds like it could be Bach or Beethoven! Can you tell us what the music is? Thank you Jeff, as always an outstanding video!

Hans Zimmer?

Well said👏🏼👏🏼👏🏼

Yes it is,unfortunately the same can't be said of the bridge!

Actually, I think bridges are built to fall apart under certain circumstances, but in sections. In most cases, losing 1 section is preferable that taking the entire bridge down. In the MV Dali case, though, I (as an uneducated guess) think because the Dali missed the dolphin and hit at a point high enough to impact the brace before the cement base, so much lateral torque was transferred to the framework that it totally failed. If you watch one of the earliest videos, you can see that when Dali impacted, the support brace between the bridge and the cement base structure failed - the bridge frame fell onto the base structure, just as the Dali caused that to fail as well. What I thought was interesting was that there were only 1 or 2 brackets (maybe 1 or 2 per traffic direction) between the bridge framework and the base structure. If that's true, they might have also been weakened of time after 50 years of weather and traffic. Anyway, once that (those) braces failed, and the underlying support base collapsed, the rest of the bridge was drug down until the failing force exceeded the connecting strength capacity - you can see that in the initial (failure sequence) video. I'd imagine the weight of the bridge itself caused almost all of the damage. The Dali was stopped almost instantly by the initial impact started the chain reaction.

Please explain the tug boats response when the ship sent MAY DAY signals.

YAH, but Baltimore is still a failed city. A veneer of civilization for the tourists. Nothing but poverty and blighted neighborhoods for the citizens.

Ditto. My opinion is that the tug, barge, demolition and salvage crews are the people who deserve all of the credit - not the "Unified Command." That group of blow-hards might have been yelping their horns for the cameras, but I'd bet the progress would have been as speedy, if not faster, without the bureaucratic posturing - the crews certainly didn't need instructions from bureaucrats to know what to do, or how to do it. I mean, really - they were working as a finely tuned, well oiled, orchestra (if you'll pardon the mixed metaphor :)) from day 1.

@@OopsWhatIMeantToDo completely agree. Although, the mouthpieces did keep everyone informed, albeit very dramatically.

The only thing that saved her was that the sea (river) bed was only 30-40ft deep at the support. She was squished between the weight of the debris and the muddy bottom. Luckily it was directly downward, or her bow would probably twisted off under the stress

@@OopsWhatIMeantToDo good point.

You should visit the port of Baltimore

What you are seeing here is really a branch of the ocean; the flow is back and forth with the tides.

Really? I just bought some beach front property in Arizona from an online realtor sight unseen. I'm moving there next week.

@@jps101574 welcome!

@@Pamudder even MORE awe - full!

It’s getting repaired at Norfolk VA

Glad you like them!

Thanks for the info! I was curious whether Dali was repairable after this, or would need to be scrapped! She is tough, despite her gaping bow!

Right? I have not been able to look away from the Dali. I know zip about shipping or anything maritime, but this has been fascinating.

Unsung heros!!! 🎉 A similar kind of tugboat crew helped guide the battleship New Jersey from its berth in Camden, NJ to it drydock location in Philadelphia.

there are actually just as many containers in the ship, as you see on the top.

Containers are loaded following a plan. And not just by the time they arrive at the dock. So heavy ones go down the holds first. And they are also distributed evenly along the ships full length. This is all done by computer to get the ships center of gravity not over its metacenter's height. The metacenter is basically the axis the ship's hull is rotating about according to its shape of the cross section. So if a ship rolls to one side the forces from the displaced water on the hull's shape try to right it up again. If the c.o.g. is below that metacenter the ship will recover. If not it capsizes. All a matter of simple physics. One container may have very different weight from another. Only because they look alike they don't weigh the same. One might have Unobtainium in it the other styrofoam insulation sheets. Think filling moving cartons with books or with a duvet. One you will not be able to lift the other you will do with ease. And those filled with books go down deep in the cargo holds and not under the captain's nose at the top level. The light weight of many containers is actually the reason you see them stacked up so high. Conventional cargo ships never had the cargo going so high. At max they had some light stuff on deck 10 feet or so high.

@@user-sm3xq5ob5d Very thorough and helpful comment. I ❤ your "Unobtainium" reference. Best Wishes. ☮

Its a little thing called ships ballast. Google it.

​@user-sm3xq5ob5d There is a problem with the loading of container ships when they at the ports where they are loading full containers. This happens especially in the far east and in some ports in Europe and other Countries. Not all containers are weighed before loading onto the ship. The containers documents are obtained from the shipping agent and weights are stated on the bill of ladings and other loading documents. Certain countries in the far east have load restrictions on several highways, because heavy weights damage the road, so the weights of the loaded containers are altered so they can be transported on the highway to the port to be loaded onto the ship. If this is done with hundreds of containers then the ship is effectively overloaded to below the calculated draft marks. This creates hugh problems for ship's officers and Master of ship because certain heavy containers must offloaded from the ship in order not be overloaded. This is a time consuming and expensive exercise that involves many container moves. The reason it is done in Europe and other countries is to try get away with paying less to ship a full container that has its declared weight less than its actual weight.

Crane crews: But we do. And we will charge you accordingly.

Well it's Your Job to Learn. Finally take some Responsibility.

It was brought over to off load all of the containers.

would love to hear their input on how that appliance works

hmmmmmmm I know a guy

The blackout on the dock was due to the generators tripping because someone closed the wrong exhaust damper. The blackout at the Key Bridge was because the step down transformer tripped - the generators stayed online throughout (just not connected to the ships low voltage grid). It was in the Coast Guard report.

Music to my ears! Thanks for tuning in.

they decided to keep the roadway on the bow as a reminder

Some of captains were having a hard time finding the audio on the normal channels during this move.

Someone was direct them.

@@jeffostroff I wonder who it was and where they were located?

Well this is the kind of thing tugboats do on a daily basis so I'm sure they've had it worked out for years

I get my music from Storyblocks

Yes, generators are on to supply power to ship, but not sure main engine was online

No one could point to definitely where water was being let out of Dali, although several people claimed you could see it dumping out of the bow, but it was a metal truss piece sticking up out of the water. I could not see any evidence of them emptying the ballast, but unified command said night before they would empty 1.25 million gallons

@@jeffostroff Maybe that's why the Dali sat there for hours secured by tug boats before they tossed it away?

The last tune sounded as if it were set to a sonar beacon. I will ask Jeff for a link to the source.

From Storyblocks

They will either smash it with a wrecking ball and grappl it off, or use a huge diamond chain cable saw to slice it into smaller sections and rig and crane it off

I reckon they'll do it in the repair dock, not at the container terminal where the ship sits now. Most likely the bow needs to be cut off anyway as there is deep structural damage, not something which can be fixed with some hull patches. Major effort to build a new bow, it's not something from the shelf. Maybe it will be built at another wharf and transported to the repair wharf in sections.

laws of buoyancy are amazing

There may be other videos on the engineering circumstances concerning the power failures or as NTSB releases new info. There isn't likely to be much more for me to cover until new designs are presented for a replacement bridge. I still have many other engineering disaster that I had been waiting to make videos of, along with the DIY remodeling projects.

yes definitely not a cruise ship, even them many crew cabins on cruise ships have no windows

After unloading they will limp it to Norfolk, VA for repairs

@@jeffostroff Thank you.

only tugboats

tugs only

@@jeffostroff thank u

I heard going to outbound ships, then Dali transfers over to Norfolk, VA for repairs

@@jeffostroff thank you, Sir.

The spot they parked Dali in is not under the cranes so not sure what they will do
