The one link above where the guy is talking about how it happened in the inset box, said it was too short a time to deploy tugs. They would only have been used to undock the ship.
Seems to me having them escort it all the way out is the way to go now.

That's a lot of hacking attempts for one week. I'd think the ships systems would be air gapped to prevent that from happening.

It's not just the ships, it's the whole infrastructure. Container logistics and management, billing, customs clearing, navigation, etc.

I'm not real computer savvy. He's the whiz. He has ethical hacking certificates and degrees and certifications that boggle the mind. He can hack into your stuff in under 5 minutes.

He tries to explain it to me but it's like he's speaking a foreign language. Most people think hacking is credit cards and bank accounts. That's small potatoes. The Big Boys go after information systems and navigation, crippling your whole infrastructure until you transfer Bitcoin or other untraceable assets.

I've heard of the cyber war that is happening behind the scenes. Something we're lacking in protection of from what the guys I've heard say.

I recently retired after an almost 40 year career involved with designing, building, repairing bridges in the metro NY area... Having said that I am by no means an expert.. I was still learning my craft when I retired...

The Key bridge appears to be a continuous span cantilever truss bridge... Even though bridges are designed concerns for safety and factors of safety.. many structures have been upgraded to meet the seismic requirements. However design concerns would not include an impact by a large vessel...

Most bridges with a navigable channel have a protection system (dolphins or fenders)
to protect the piers on either side of the channel..

However the dolphins wouldn't stand a chance being impacted by a 117000 ton ship going X knots..

From the pictures and videos I have seen the ship hit the pier directly at a 90 deg angle. destroying an intermediate pier.. and then like pulling the wrong piece in jenga.. the bridge came down..

Craig - thanks for your input here. Can you explain what we're seeing on this map for dunderheads like myself? TIA!

Really interesting posts, Craig.

Thanks.

link to a video of the collapse. it went down quickly

Yellow line is the now missing bridge. All the red dots are shipping ports. Baltimore is largest roll on roll off facility on the east coast. The ports handle containers, cars, trucks, coal as well as sugar (Dominos is one of the top left hand dots) and cruise ships. Everything will divert to Norfolk Va, NJ and NY ports. Much larger for container freight.

Would think the channel will be cleared relatively quickly as they can cut and pull the steel structure. That would get the port back open and functioning.

Fortunately the road traffic over the bridge is probably less than 10% of the total traffic moving north-south in that area. Most of the vehicle traffic uses the two tunnels that you can see slightly above the yellow line crossing the water (I95 and I895 tunnels). Bridge only has 11 million crossings a year (30K a day).

OK thank you, jrj! SmileWavy

I would think the time of the distress call would be more relevant.

Better explanation than anything I've seen on TV. Thanks.

Since when did PPOT become a news source as good as other corporate news product?

Well... I learned about this collapse this am from pelican.
I watched the live collapse of the bridge from links here.
I didn't see too many cars going back an forth at the time, but as a pelican I thought about inertia- a car moving at 50 mph or more forward with a sudden kinematic acceleration in a gravitational velocity hitting water at a high rate of wtf stopping flat on some cold water dime.

What would be the odds of not only surviving that impact, but negotiating a Tom Hanks castaway sinking plane of sinking car and debri to get back to the surface?

I saw that movie in theatres when it came out, I didn't enjoy it. I was simply sick to my stomach.

When I went to work this morning, I drove a bit relieved. In a worst case scenario, I might hit a deer. :rolleyes:

But then, it occurred, the lights on the bridge weren't (for the most part) moving. It was a construction zone. Then my thoughts went to a construction suit. Heavy duty. In the rescue squad we had to wear steel toed boots for safety. Did they?

Good God.

That wasn't swimwear.

Not an uplifting post, but, my heart goes out to them all.:(

Effin' awful. I hated that bridge on a good day.

I learned all of this from my Son. He has been traveling A LOT securing ports in Long Beach, New Jersey, Savannah, Miami, Jacksonville and next month Austria and Switzerland.

Funny enough he is based out of Gilbert Arizona. He gets calls at all hours to work on cyber attacks which he enjoys. He also generates company wide "hacking emails" and counsels those that mistakenly click on the embedded "hacking link".

He's also a Star Wars Geek....

This picture is very odd.... note the protection around the towers carrying power lines... looks quite robust...

The sharpness of this photo sucks... but I see no protection around the piers of the bridges.... not that they would do anything with the sort of impact from the ship

This photo is sharper and I'm not sure if the four roundish objects seen are supposed to be pier protection...If so poor design

That was one of my first thoughts too. Soon the blame game will start.

Also there is a very big boozing culture onboard ships. I hope the captain/pilots weren't drunk and started pushing the wrong buttons.

22 crewmen of Indian nationality were on board. These big ships can have satellite comm back to headquarters about real time operating & location data. The bunny trail is there to follow.
Maersk shipping has some explaining to do. Less than a half hour from the dock all power is lost.

A news report I saw this morning said that a recent inspection of area bridges resulted in a "Fair" rating for the FSK span.

I was just thinking the same thing. I've been checking this thread for updates because I can find out about things quicker here. [emoji3]

I meant the maintenance of the ship. If it did lose power (and control) could the correct maintenance procedures have prevented this.

I also was wondering why the bridge pylons didn't have any protection around them especially being a busy port. [emoji53]

In a handbasket!

Well, it's not every day someone is named Baltimore's FBI Field Supervisor and that night a cargo ship takes down a major bridge shutting down the ports. What are the odds?

Dunno if this has been reported here, but tonight on the news they said there was some kind of alert sent out by the ship that let the police know the ship had lost control.

It gave enough time for them to get in position to prevent any more vehicles from coming onto the bridge... and there was enough time for those on the bridge to get off. Supposedly, the work crew were the only ones left when it went down.

This video shows a good many vehicles were crossing right up until a very short time before the impact. Start watching about 56 seconds in... it's sped up, but you get the idea...

Yep ... any breaking news will likely be posted here before I see it on the "news"!

Unfortunately, I also read a bunch of political BS here too ... and I just don't watch "some" news at all :(.

Damn Paul .... give it a rest or take it where it belongs ...

[QUOTE=KC911;12220889] Should have been called what it is, The Conspiracy Theory Forum.

Cause they're useless against something the size of a ship. Those barriers around the power poles are there to protect against errant pleasure craft and nefarious actors. If something half the size of the Dali hit one, it'd wipe it out instantly. OTOH, the bridge pylons easily survive a pleasure craft strike.
Been in and out of their many times under sail, have seen them up close.

And yeah, I wouldn't be so quick to rule out bad actors. I'm not a tinfoil hat guy, but the timing of this days on after a terror attack in RU that Putin blames on us is somewhat intriguing.

I dont know man, it just smells fishy.
Lost power right at the perfect time to ram the bridge.
Slightly off course, so power restored, engines on, and turned slightly to better align with bridge.
Power off again.
Hit the bridge with the exact tool needed (big heavy cargo ship), at exactly the right angle, speed and location to completely destroy the bridge.
Too many lightning bolts hitting at the exact place and time needed for this to happen by chance.
Not saying it was, just saying.

It wasn't the same ship (Evergreen) that couldn't manage the Suez Canal....but maybe the same captain.

Multiple sources are saying the same thing. Harbor pilots were operating the ship at the time of the wreck.

"The owners of Singapore-flagged container ship “Dali”, which was involved in the incident, said the vessel collided with a pillar of the Francis Scott Key Bridge in Baltimore while under pilotage with two pilots on board. All crew members, including"

^^^ Yep that's what this article says .

https://www.straitstimes.com/world/united-states/baltimore-bridge-collapse-port-pilots-onboard-were-us-locals-says-firm-that-manages-stricken-ship

It makes no difference who is operating the ship if the powerplant fails at low speed. No rudder steerage below a specific minimum speed, you steer with prop differential or tugs below that design speed. So if the powerplant is disabled below say 5 knots or whatever, you're adrift. And at even 3-4 knots a container ship goes a LONG way with just residual drift and packs a lot of energy if it hits something.

Re. what are the odds. If the power out happens 5-10 before or after the ship doesn't hit the bridge. The ship operates for years and an unexpected failure happens at just the right time for a disaster. I think there is a law that covers this - starts with "M".

2 I made the pilot response to counter that it was "maybe the same captain ".

They had power outages for a currently unknown reason. The ships pilots/crew attempted to minimize damage by taking several evasive actions. They knew that serious trouble was most likely unstoppable so they called in the warning. Law enforcement acted quickly and stopped traffic which minimized the number of deaths.

Thank you, Jolly.

Harbor pilots always guide the vessels in and out of port. That said, I think the captain of the ship still has responsibility over it.

We have several ports in the Charleston area and I cross two or three bridges daily to get to my destinations. Made me think twice today.

"Prop walk" caused the ship to turn into the bridge support.

I've been over this bridge hundreds of times to see my dad. Tragic day for everyone. And hard to believe these ships don't have redundant power systems.

Apparently the ship did not lose power. The lights flickered because at that point they went full reverse and drained all the power to the electrical system. Like how your lights flicker when the microwave turns on.

I'm surprised the ship stopped at the pillar and didn't just keep going. This tells me that bollards would could stop a ship.
