What is so critical about the Suez Canal. If it were down for a month/year. what do you think the impacts would be? Would most ship traffic simply go around Africa?

Accepting that globalization wasn't such a big thing then, the closure between 1967 and 1975 would be a good source of objective 'what actually happened' data.

There appears to be little "high-end engineering." Just a high tide and a bunch of tug boats.

High end engineering uses the simplest and most cost effective solution to get the job done right. It would have been a mistake to throw expensive, complicated solutions at a problem that had a relatively simple solution.

Oh hey, they fixed it, - without destroying or imposing significant additional damage to any of the cargo - without destroying or imposing significant additional damage to the ship - without taking multiple weeks - without needing to ship a trillion dollars'+ worth of equipment halfway around the world It's refreshing to see high-end engineering performed so competently.

What I wonder about: how is such a rescue contract negotiated? There is likely willingness to pay, but it is difficult to judge what a reasonable price is, and it may not even be clear who is culpable in advance. Do they have contracts in advance with the shipping companies?

A bit more detail here [1] and here [2]. A combination of vacuuming sand, high tide, and tugboats did the trick. [1]: https://english.alarabiya.net/News/middle-east/2021/03/29/Su... [2]: https://www.aljazeera.com/news/2021/3/29/ever-given-turned-8...

Is it just me or is the Evergiven listing to port?

There were reports I read earlier that part of the unsticking process was pumping fuel and ballast water around to remove as much weight as possible from the bow of the ship. It's probably unbalanced the ship a bit and they're just waiting to get to the lake to pause and fix it to allow shipping to resume as fast as possible.

> I’d be surprised if they aimed for their ship to arrive n days before the spring tide in case it got stuck. That's not what I'm saying. I'm saying that after the ship got stuck, they certainly incorporated the tides into their plan for how to unstick it. If the tides had been less amenable, they would have come up with a different plan. So their plan didn't get "lucky", their plan was predicated on the tides being…

Without the high tides the amount of material needed to be removed would have been dramatically higher. That’s the point and the absolute bit of luck. Without the high tides they likely wouldn’t have been able to get it unstuck as quickly. Search for slope/fill volume calculation charts - the amount of fill required to be removed as you go deeper is logarithmic, NOT linear. It was VERY lucky they had the highest tide…

Did the ship crash during high tide or low tide? The tide 6 days ago when it got stuck compared to today is more important.

High tide did more than anything. If it had gone beyond Wednesday they likely would have been screwed as the high tide was set to start dropping each day after Tuesday. Good thing they started dredging right away.

I just adore that us little humans got our big boat stuck in the sand and uncle moon had to reach down and fix it for us.

No, he really wasn't.

Lol - quoting himself to back up his performance?

How about linking to others and not him defending his performance. Of course he’s going to have excuses.

Live a little and maybe even pick sources that might not align politically with you too for an alternate POV. Prevents “surprises”. Because as someone with no love lost on either party the election results were not a surprise - you just have to look across all sources, not just the ones that tell you what you want to hear.

This makes me question that shouldn't we have another canal built? Like if so much of the world's economy depends on this route shouldn't we build an extra canal to speed up the transportation and also act as a redundancy

Where do you propose building this extra canal?

Cue Elon Musk promising to build a tunnel version of it for $5 million total cost, opening fall 2022.

The seasonal variation in the tides is like 20 centimeters. The draft of the ship is more than 10 meters at the bow.

Good thing we are talking normal monthly tidal variations (not seasonal) which vary by meters, not centimeters.

Not in Suez though.

Yes, the high tide is a better opportunity to do it, the tides over the next couple of weeks are still within 20-30 cm. The worst day in the next 30 days is 60 cm below the highest.

But maybe the dredge only made a few centimeters of difference running for 5 days, who knows.
