It’s like the I95 bridge in Philly. As soon as it collapsed you had people going “decaying infrastructure!” Ignorant of the fact that the bridge was brand loving new, it just been replaced as part of an enormous infrastructure product that had been redoing/replacing that entire miles-long section of 95 over the last several years, and no, it collapsed because an entire tanker truck of gasoline crashed and burned underneath it and jet fuel softens steel beams. You can argue that the design basis incident for a highway bridge should be “must withstand 9000 gallons of gasoline fire,” but you can’t argue that the bridge failed because it was decrepit/uninspected/in poor repair.

TEMPLE GRANDIN OS posted:great job so far kormak what's going to be a worse impact to that city, having none or smaller shipping industry, or dealing with an accident on this scale. what's the likelihood that another ship of that size can have a failure like this in the future? it's dependent on each vessel at that point.

One of the benefits of social safety nets, which includes insurance, government support etc., is that we don't need to let perfection be the enemy. Capital is going to be destroyed so that you can post on the Internet and eat cheeseburgers and poop on a toilet. Capital includes people and their time and lives and limbs. It's unavoidable unless you opt out of society. We can't just close a port cause the big ships are near bridges just like we can't stop driving to the grocery store because drunk maniacs are operating heavy equipment on the way. We manage this by social programs to fix things when something inevitably goes wrong wether a bridge falls down or your leg is amputated after a car crash on your way to buy Funyuns.

KoRMaK posted:i dunno man still seems like whether it's train boat plane bridge tunnel or freeway a "freak" accident is just a couple moments away that has a catastrophic domino effect. maybe ships that size which could take out a vital bridge shouldn't be able to sail near its critical support structures. maybe ships that size should be moving more slowly until they are past the bridge. maybe the tugs should escort the ships for longer. You clearly have no idea how risk management works. I'm surprised you even have a computer and aren't afraid that you're going to strangle yourself in the cords or trip and impale yourself on your phone. What's more important: your life or you being able to post?

lmao i worked in risk management for years. ya know what i learned? is that people like to throw their hands up 'gee whiz there are no possible improvements that could have been proactively identified to mitigate this risk.' slowing down not an option, longer tug escort around sensitive areas, inconceivable. in reality there are very practical options that could be developed and implemented

First loss of power (presumably, who knows if they were dealing with any smaller issues on-board ahead of the apparent full-power-outage) to bridge strike was like four and a half minutes?

Remember it's all about risk management and economics. A human life is worth $12,500,000 to a risk management engineer. If the cost of the improvements to prevent hot ship on bridge action is a billion dollars the engineer would need to prove they would save 80 lives to build them (and the politicians would actually need to find the money). Simple math.

Away from the risk mitigation design chat, I work in construction inspection and testing, and have spent PLENTY of time working with road crews. My company has a major interstate bridge project going right now and for the next few years. Roadwork on open traffic corridors is already stressful, and seeing that there was a road crew on the bridge at the time was absolutely gut wrenching.

You can protect foundations with fenders. The exact name escapes me, but there are designs that are half-submerged and use the mass of the water to absorb energy. They can deflect a ship away, but only if it's coming in at an angle. In a head-on collision they get squished just like anything else. Probably still worth installing.

Also when they say "a ship" they probably mean a large yacht or ferry or something, not a hundred kilotons of container ship

True. It's also very common to require ships to have one or more local pilots on board who know the local terrain. I live near the busiest canal in the world and anything going through it larger than a certain tonnage must have pilots on board, and ships still manage to destroy the lock gates with distressing regularity…

Well, the Locust Point Marine Terminal which is now blocked because of the accident, is the largest RORO port on the Eastern Seaboard and is tied into the rail and road network that needed to use that bridge. The harbor speed, I believe, is 4-6knots max (I seem to remember that from when I lived in Fells Point), and at over 100K tons, even at 4 knots that's a fuckton of kinetic energy that will vaporize pretty much any structure that it hits head on. The Patapsco is a pretty slow-moving river, and it has huge sediment buildups that the city has been dealing with since the 18th century. which is why the ship when it lost power and steerage looked like it was aiming to ground itself by heading outside the dredged center channel. (It's about 20' deep in the shallows). As for tugs, it looked like the ship had just been cut away just before everything failed. but if the tugs had remained attached there's no way they could have stopped it, the ship was using its props and that inertia comes into play again. Could they have steered it through the gap? Maybe? Harbor tugs and deep sea tugs are two very different beasts. I was a combat diver and worked around harbors and tugs a lot. Deep sea tugs have insane power-to-weight ratios, but pay for it with their drive units not being as responsive. Harbor Tugs are agile as gently caress butdon't have the same stupid amounts of thrust, ridiculous thrust sure, but not the absurd deep sea levels.

I think it's 6 but the governor said it was moving at 8 when it collided. Either way it's a fuckload of momentum. I punched these numbers in based on what was said at that press conference and yeah I don't think they designed it to handle a 788887. Compared to the WTC that pillar was a toothpick, and you're throwing about 4 times as much energy into it? The channel is far more important than the bridge at this point. The two tunnels are already congested and aren't going to become completely gridlocked by the normal commuter traffic, and for trucks passing through on 95 that can't use the tunnels, going the other way around 695 is about the same distance and has no tolls (but generally higher traffic).
