The dolphin would be designed to move. So even when it DOES, there is less energy for the bridge to absorb. Let alone, it would not rip a whole in the vessel.
The whole point is to reduce the damage to structural only and not blocking the water.

There's a picture floating around of the aftermath from a helicopter or drone shot. The boat went through the bridge support by like 40 feet. I'd link the Bluesky post but the author went semi private.

the momentum of this is almost impossible to put into words. If an average 15,000-ton freight train was traveling 100 mph, that's what you'd need to somehow stop in like ten to twenty feet. I just don't think the physics lend itself to the cost vs frequency vs consequences.
in industry this would be where you start to look at layers of protection analyses. In aviation we'd gotten that down to a science before Boeing ****ed it up. Shipping should have the same protections aircraft do. The consequences are so, so much worse for boat disasters. The last (and to my knowledge, the only) time a plane disaster caused billions of economic impact, it was on 9/11. I can name two in the last five years for boats. I'm guessing there are more.Last edited by dxmnkd316; 03-27-2024, 08:48 PM.

To say “meh, nothing could have been done”- yea not so much. Could have lessened the impact on shipping- deflect it enough to totally damage the bride but keep the shipping lane open.

When I was in San Juan, I watched a cargo ship like that come into port. The ship was guided by two tugs, one stern and the other aft. If the idea being proffered was to have tugs guide in and out of port, it happens elsewhere.

To put in perspective how big this ship was...it is larger than the tallest skyscraper in Cleveland. I don't think a tugboat would have helped much. It's like the idiots aaking why they didn't throw anchor (like it's a phucking fishing boat) even if you could on the fly pretty sure Newton has some thoughts as to why that won't work.

In other state news, Disney and Florida have reached a settlement in their ridiculous districting suit. Few details yet, but right wing media is ignoring the "settlement" part and just going with "Disney drops case, DeSantis wins".
The one thing we've been able to parse out fully is that the woman who was put in charge of the special district is a long time State/Disney liaison who orchestrated Disney's carve-out from their idiotic tech/social media bill a few years ago. She's worked for the state but alongside Disney for many years.
So my guess is that the state installed her to that position and compromised enough that Disney said "ok, so you're assuming all responsibility and debt, but we still get to do almost all of what we want? deal."
I mean, come on. Disney isn't going to lose to some empty boot like Ron DeSantis.
Also important to note, this settlement is separate from the federal lawsuit, which is still pending.

It's like a 100 year flood. Yes, it may happen. Odds are it won't. You have to make your best assessment based on the data you have, and work from there. Nothing in this world is guaranteed 100% safe. **** happens.

If you want to talk preventative procedure, you also have to look at how there is a "local" pilot on board who guides the ship out of the harbor. They are there to provide "local" knowledge regarding things like currents, navigation oddities, channels for safe passage, etc. That's who was guiding things when the power failures occurred on board and also who called for the last second emergency maneuvers.
So it's not like there is total lack of prevention going on here.

This bridge was also built almost 50 years ago, when the largest cargo ships weren't nearly as large as this one was.
