here's a great moving image depiction of what happened with the Ever Given/Evergreen

I was trying to understand how it happened. This explains it.

That's what happened in SuezCanal

1. K&R for visibility. nt

2. Thanks!

3. After watching that video, it's clear that they were going way too fast!

 
?

Just kidding.

10. I always travel very quickly when I'm under a purple shadow.

And I've yet to run aground in any of my Suez transits. I mean, the tow path is right there. Just follow the camels. Can't miss them.
The Panama canal thing is another story. Been lost a lot or times in that crazy lake in the middle. What's up with a lake in a canal anyway?

[FBaggins]

18. The lake is an essential part of the canal

It's the reservoir that supplies water for the canal locks. Most of the canal is well above sea level, so there would be no way of transiting unless the locks could lift you ~ 80-85 ft and then lower you on the other side. Each cycle loses water.

4. Fascinating. K&R n/t

5. another graphic: 2 big container ships immediately ahead used escort tugboats, while she didn't

WHAT WENT WRONG at the Suez Canal? While the Ever Given sailed, another vessel decided the wind was too strong. And 2 big container ships immediately ahead used escort tugboats, while she didn’t

6. That thing is the size of a skyscraper. Surprised nothing bad happened beforehand.

7. He ran aground at 13 knots. (Speed limit is 7)

Parece que sofreu o "bank effect" desde o início do canal (popa cola e abre a proa). Foi aumentando máquina pra tentar sair desse "bank effect". Tangenciou pelos dois bordos até que foi vencido. A popa colou de vez a bombordo jogando a proa toda pra boreste. Encalhou a 13 nós. 🤔

(Google translate from Portuguese)
It seems to have suffered the "bank effect" since the beginning of the channel (stern glue and open the bow). It was increasing the machine to try to get out of this "bank effect". He fell on both sides until he was defeated. The stern glued once to the port side, throwing the bow to the starboard side. He ran aground at 13 knots.Thinking face

Prolly sped up trying to regain control, but I imagine that’s why one reason it’s jammed so far into the mud.

8. Was there a pilot on board?

I just read there are one or two local pilots required for passage. I believe they are only required to supervise the captain.
Same thing here after a tanker ran aground in the late 1980's. Here they take over the ship.

17. Thanks

interesting info there.

9. Now I finally "get" what happened,

It was clear as mud to me, until I saw this and and the tweet further down thread.

It kind of reminds me of what happens with a car when you take a curve too fast, then overcorrect when you realize you're about to run off the road and try to straighten out. Except in a car, you have a decent chance of getting things back under control as long as there's no oncoming traffic to dodge and the road conditions are okay.

Piloting a giant container ship down a canal that's barely wide enough for it? Totally different kettle of fish!

11. It happens

My Destroyer ran aground in ‘76. Our prop got stuck in a sandbar after loading the aft storage with 3 weeks supplies for sea ops. Took 12 hours to get out and then underway. I was on port watch in CIC which was off during night. The Starboard watch chart plotter and Ensign on the Quarterdeck got serious ass chewing. We did not get this attention.
Not our finest moment. USS Semmes DDG 18. One bad ass tin can, other than that day. Scap medal now.

12. Side thrusters?

IIRC, the cruise ship I was on 7 years ago had bow and stern thrusters, which were rather important when carefully navigating the Houston channel to avoid stirring up the oil spilled from an accident. Does this ship not have such equipment? You’d think the ability to generate sideways thrust ought to be required on all the biggest ships, especially if they’re routinely going through canals narrower than the ship’s length.

13. So, almost like the Shipping transport version of kidney stones?

[USALiberal]

14. Who here hasn't done this at some point???? Nt

[IcyPeas]

15. Yeah, every time I do a three-point turn
