What Really Happened at the Suez Canal? 

Ko‘rishlar soni 1.8 mln

Exploring the engineering principles behind the recent obstruction of the Suez Canal, which caused a weeklong disruption in global shipping traffic. I give a brief overview of the bank effect and dilatancy of coarse-grained soils. Hopefully, the video helps you understand a few of the engineering challenges associated with navigating massive ships through tiny canals and what can happen when they run aground!
- I incorrectly described the landform as the "Suez Peninsula." It is the "Suez Isthmus."

I don't think it 's true that the squatting effect applies when passing under the Great Belt Bridge. I have heard this story before and passed under said bridge a couple of times with 19k TEU ships (400x60m). Every captain I've asked about this matter believes that it is not true. This makes sense, seeing as the depth is roughly 60m, which would make the depth under keel more than 40m with draught at 17m. If you have any sources to the story, I'd love to read them! Great content. Having passed through Suez just a couple of days after it was freed, and being a marine engineer, this was a very interesting video.

How about the ACTUAL reason? It's tied to The Deep State Cabal and the now deceased Hillary Clinton. Our U.S. Military Special Forces white hats seized it. Inside they found tortured children in cages for Adrenochrome and advanced equipment Bill Gates intended on using for the next plan-demic, (anti-cow gasses) that's why he bought a lot of farm land recently, to grow his chemical infected crops. The equipment was destroyed and the children were rescued. The TRUTH about THE BIG LIE AND EVERYTHING else WILL come out to the public very soon.
Garfie489 9 soat oldin
No no, the ACTUAL reason was because Optimus Prime was known to be onboard, so Donald Trump stormed the ship with the power rangers and captured him - before revealing himself to be MEGATRON!!! In the ensuing fight, the ship crashed into the side of the canal. Now answer me, whose bullshit story sounds more fun? - US Military wouldnt allowed to be involved, its on Egyptian soil and it blocked the route their entire economy relies on. You realise Team America: World Police was not a documentary right? - thatd be a major international incident if it were true. Look i realise for average intelligence to be a thing, half the people need to be below it - but could you work on raising the standard please?

I didn't see any Egyptian canal company mention the Egyptian experienced pilot and why he was not able to fix the issue before it was too late. There is high winds there regularly so why has this not happened before as these large ships are regular transiters ??. If it was an Egyptian fault, you will not hear about it. If its a big canal design issue made more dangerous due to these supermax ships, then the Egyptians will bury this report as this would endanger such a massive money earner and potentially drive some shipping around Africa. If its a large ship issue then captains will need more training as the efficiency of these massive container boats is so obvious. The bad news is that the insurance payout is going to be so large as to require the insurance pool thats there for massive payouts that no one insurance company could provide and so that means higher insurance premiums and thus higher shipping costs. Expect your Apple Notebook from China to rise in cost unless fuel prices fall alot/shipping has its regular price war and there is a miracle cure to shippings dirty emission problem that will require trillions of cash in investment over the next 2-3 decades.

@Practical Engineering: I had a question, that has been on my mind about the $ 1Bn claim made by the Suez Canal Authority on the owners of the Ever Given. No doubt the amount appears to be high. However, what I couldn't understand is if the ship was navigated by a pilot employed by the Authority, how can they make claims from the owners of the ship? I would assume it is complicated and they are holding the ship and cargo because they are in a position of advantage. I am sure, for an amount this high, this matter will be taken to all levels of international adjudication. Still would like to hear your views as an expert in this area.

@Attila Pollak Megatron and Optimus Prime also do not get mentioned. This channel is based upon facts, and given child trafficking is a non issue in this incident - theres no need to mention it. If you believe it occurred, then you seriously need to improve the quality of your news stories. Its doesnt take much logic to work out a container ship is probably the worst way to traffic people

Hey Grady, do you think they could have used air to dislodge the bow? I've seen videos where sand, when air is pumped through it, basically turns into a liquid. I feel like drilling to beneath the bow and stick air hoses down there might have helped?

One day I was trying to pull a wooden fence post out of the ground. It just would not pull out, despite the fact it would wiggle. Something told me to get a garden hose and run water into the hole. The post pulled out easily. I think the Suez Canal engineers should try using a garden hose next time.

Youd think if they wanted to stop it, theyd have done so in such a way it doesnt suspend the keystone in Egypts economy for an unknown amount of time - like take it to port, keep it in the Bitter lake, etc. All options available if that was the genuine reason.

What really happened was a major socio political move by the DS...and why did he draw a male genitalia in his route plan before getting 'stuck...
Garfie489 2 kun oldin
He didnt. The boat was circling around a fixed point, as were all other ships in the vicinity at the time - watercraft are well known for not exactly staying still. During one of the circles, the ship needed to move out of the way of another ship moving through the area, hence once circle was elongated - this is shown and explained in the real time viewing of the map. Its not really the best conspiracy theory in the world - its a well understood topic.

Same effect in aircraft wings. Lift is not mainly created below wings but on top of wing by greater wind speed compared to below wing. It's not intuitive and thats why flat wing needs large attack angle to create difference between top and bottom of wing

I'm in the camp of big gust of wind pushed the ship to leeward and there was not enough room to swing the stern to push it back into the center. As they tried the bank effect took more toll on the volume of water on the leeward side. All the bow thrusters in the world were not going to keep it off the bank ... Imagine the forces on the Ever Given of just 20 kts of wind and all that sail area ...
