I don't think people are giving enough credit to how stuck the ship is.
Look at some of the photos of the front of it. Look at how far out of the water it is sitting. The ship might look like that if it were totally empty, but not when it is full of containers like this.
Some people saying: just drag it off of the sand. Okay! And what happens when that causes you to rip a hole into the hull of the ship? Now it's really stuck.
Some people have suggested unloading the ship. I don't think you realize the infrastructure required to unload a ship. You're basically asking to build a port in the middle of the egyptian desert. That isn't going to happen.
It's really stuck. It's probably going to take a couple of weeks to get it unstuck.
> Some people have suggested unloading the ship. I don't think you realize the infrastructure required to unload a ship.
It seems, though, that a partial unloading is being considered by a professional in the field according to quotes in an article in The Guardian [1]:
However, Peter Berdowski, CEO of Boskalis, a specialist dredging company that has sent a crew to the scene, said data so far suggested “it is not really possible to pull it loose” and that the ship may need to be unloaded. “We can’t exclude it might take weeks, depending on the situation,” Berdowski told Dutch television.
He said the ship’s bow and stern had been lifted up against either side of the canal. “It’s like an enormous beached whale. It’s an enormous weight on the sand. We might have to work with a combination of reducing the weight by removing containers, oil and water from the ship, tugboats and dredging of sand.”
Just handed out the updoots left right and sideways myself, because my points on this video comment just hit the triple digits (!!!). What a time to be alive.
And your appeal is to what, exactly? Answer: It's to the "authority" of an opinion offered by an unidentified newcomer, with no indication why the rest of us shouldn't dismiss the opinion as unhelpful noise.
In contrast, points and longevity serve as a rough, very-democratic measure of a poster's cumulative contributions to the community here, and thus (indirectly) of how well the poster has grokked the local cultural norms. That, in turn, gives readers useful information about the weight that they might wish to consider giving to the view(s) expressed by the poster.
(Apropos of which: I see that you still have a total of -1 points for the all of five days that your account has been active.)
Wow, thanks; I was wondering if anyone would notice - there was one or two a while later, and I was happy someone got it.
Then came back just then after a few busy days and had to do a massive double take at the number of upvotes; I probably shouldn't discuss the actual number, but it's my most upvoted reply ever - there must be a lot more punsters here! :)
I used the reference to the NZ "Beached As" due to its brilliance, if you haven't seen it it's a silly treat especially if you love the accent.
And again I greatly enjoyed that sardonic tone of the original video, which I saved for future repeats.
holy crap amazing. Why doesn't news editorialize like this anymore like this reporter did at the end? Simple, obvious, and stated fairly. You don't always need to talk to the guy who thought the whale hailstorm was still a good idea.
Old school journalism? That kind of reporting takes too long — two minutes until the event is shown — to lay out the facts in a responsible way... giving everyone a clear idea of the initial problem, the proposed solution, and what the proposed solution was supposed to accomplish.
Aside from taking too long, it fails to manipulate the audience by giving them a prepackaged take that aligns with the viewers' preconcieved bias, enrages the opposition, and generates audience affinity with the news outlet. Where's the profit in that?
I'm a little confused by this take: editorializing doesn't happen anymore, which is sad. It doesn't happen anymore because editorializing occurs, which is good, because editorializing is bad?
Instead of listing possible technologies and solutions to the problem of re-floating the container ship, why not make an ordered list of worst possible outcomes and approach the problem from the least-worst?
I'll start:
1. pull the ship out of the sand by force with a fleet of tugs which tears a hole in the ship causing an angle of loll and to subsequently keel over.
Ok, I know it sounds crazy. But what if they put a correctly sized explosive(s) deep enough below and along the spine to blow and then fill the area with water, reducing the rheological load? We're talking about 100 feet underneath the canal bed, and do it with a shaped charge that'll be more optimal for the task. Just thinking about fast <1 week methods.
I was wondering if it is sand, can it be liquefied using vibration around the hull to help loosen it? Something like what they use to vibrate concrete while pouring it. https://www.youtube.com/watch?v=tV4sTbpa7Hc
So... you want to be the one responsible if it doesn't go as planned? Further blocking the canal, let alone damages to the ship and cargo on board.
Theres a reason wacky, dangerous ideas happen in the movies and not real life. The consequences of trying to look clever and failing are pretty severe.
This is a really good example of how terrible people are at judging scale. Some numbers getting thrown around downthread say there's something to the tune of 10,000 40ft containers. To give a bit of a sense of perspective, that's like trying to clear out some 200 football fields worth of semi-trucks, except they are stacked, packed full of stuff, and have no gas or wheels. And all of them are perched atop a ship that is twice as tall and there's no suitable cranes or similar equipment anywhere near the vicinity.
If you ever seen a truck up close, you probably have an idea how tricky it is to maneuver even a single functional one on open flat ground. I can't even begin to imagine what it would take to move off even a fraction of 10,000 equivalents of bricks of the size of trucks, let alone budge the massive ship off of the sand banks.
For moving containers off the best bet would probably be heavy lift choppers, the ship is large enough you could have several working on it at once and then just drop them off nearby to be loaded onto barges or something. A huge undertaking but it any weight taken off the Evergreen is less digging they have to do and the time is so expensive.
Also it's less middle of nowhere there's a pretty large airbase nearby it looks like from Google Maps and a second smaller airport south of where Evergreen got stuck so there's plenty of support near.
Like the OP said, folks really aren't understanding the scale of this problem.. If they manage to do a single crate per minute, that's still just under seven days to do them all.
An empty forty foot shipping container on its own weighs about four tons and their max supported weight is 33.5 tons, so the problem is somewhere in between for every single container. A Mi-26 helicopter, a "heavy transport helicopter" can only lift 14.5 tons, so there will be crates that can't be lifted.
Even if it was possible, and ignoring the logistical issues, you can't ignore the safety issues. Doing it quickly across seven days is going to lead to human and equipment failure, and somebody's bound to get hurt or killed. Considering how many eyes are on this right now, what do you think is going to happen the first time someone dies?
And one per minute is wildly optimistic. I guess it would be more like 20 minutes per container, which will result in a year of offloading 24/7, which is also impossible due to low resource time of helicopter engines and airframe in general (and pilot stress too).
From my experience working with helicopters in the military, I think that is wildly optimistic. Probably closer to 60-240 minutes to get each container even 100m by helicopter, with severe limits to parallel operations either in the air, or on the ground/water nearby.
Yeah, and it sounds like they can't fly that long without parts failure. It's hard to find thorough information on how long heavy lift helicopters can run for, but a new CH-54K only has an 88.6% reliability rate for missions lasting only 2.25 hours. Shit's looking bad for the helicopter idea.
However, the current estimate for mission reliability is still below the required threshold (i.e., minimally acceptable) requirement. The program office reported in November 2020 that the helicopter demonstrated an 84.5 percent reliability rate, which is short of the program’s threshold requirement and below where the program office expected the reliability to be at this point in development.15 The program office projects that the helicopter should reach mission reliability of 88.6 percent after operational testing.16 According to program officials, the main causes of the reliability shortfalls have been technical issues identified during developmental testing. For example, the reliability of the main gearbox has been one of the main factors affecting the helicopter’s overall mission reliability metric.17 As mentioned, the program office has mitigation plans in place to address many of those technical issues, but has not yet demonstrated the required level of overall helicopter mission reliability.
> Considering how many eyes are on this right now, what do you think is going to happen the first time someone dies?
Considering how many goods and how much money is being blocked up by this the response may be loud from come parties but I doubt governments will care enough to stop it.
Some estimates I saw put the estimate at 10 billion dollars of goods being held up by the jammed ship and the costs of delays caused by sailing around the Cape instead will probably put a multiple on to that number before this is all over. There are construction projects in that corner of the globe worth far less that kill far more than just a few people but that hasn't really slowed them down much has it?
From a system design perspective, it's kind of nuts that the entire planet has only one single canal connecting two major bodies of water, and it's in a country with a, shall we say, precarious government. Surely such a single point of failure is a massive risk. Granted, geography doesn't leave us many choices, but could we at least build another, parallel canal to it?
There is another alternative: going around the southern tip of Africa. While this adds a couple weeks to trip time it also saves the massive Suez Canal transit tolls.
Yeah and I'm under the impression that the fees are balanced so that it costs roughly the same amount to take either route. Ships only choose Suez because it's faster.
The Suez is at basically the one point it makes sense to build it. The next closest is off the Gulf of Aqaba and that's right on the border of Egypt and Israel. It really doesn't make sense for Egypt to go through the trouble of cutting a second one on the one in a million shot a ship gets stuck like this. The usual answer is just make sure they don't get stuck rather than spend the billions of dollars cutting a second canal would cost. Even if Egypt was somehow charged the losses for this screw up that probably wouldn't be enough to make it worth cutting a second backup canal.
The difference would be in the hyper-visibility of the deaths.
To show what I mean, compare the level of reporting and political backlash from [1], involving two construction workers against [2], involving 11 other deaths, that were only revealed after an audit. Visibility matters. I don't think it's unfair to say that if any deaths happen here that there would be far more global visibility than [1].
And besides, it's a silly armchair idea that doesn't make any sense whatsoever after ten minutes of scrutiny.
As for the weight per container issue, I would expect the heavier container to be further down in the stack, for centre of gravity considerations, e.g. you should still be able to get a significant part of the load off the ship.
This also assumes good weather. Part of what caused the ship to run aground was high winds. I imagine that any winds high enough to cause that would also make it impossible to use the helicopters. How often are the winds in that area that high in that area?
If you can get 10% of the weight down in a week, that is still better than not having the 10% gone. If you can do the helicopter offloading without blocking any other progress, then why not do it immediately?
"For moving containers off the best bet would probably be heavy lift choppers, the ship is large enough you could have several working on it at once a"
There's the crane lifting a crane lifting a crane method. [0]
Though I suspect another problem would be getting another ship large enough for all those cranes and strong enough to support all the weight close enough to the ship without them damaging each other by knocking into each other from waves and weight movement.
I also forgot about the matter of transporting those giant cranes onto the site. That itself would probably take weeks.
"Though I suspect another problem would be getting another ship large enough for all those cranes and strong enough to support all the weight close enough to the ship without them damaging each other by knocking into each other from waves and weight movement."
I don't thinks this is your concern. Desperate times, desperate measures. Likely you would fix/attach the crane ship to the container ship. I am sure they are willing to salvage two ships at this time. The daily losses must be gigantic.
I'm definitely curious to see what they end up using. If the solution ends up involving choppers, there's obviously the question of tensile load specs for all the involved parts (the chopper itself, the cables, the containers, wind considerations, etc). I don't imagine they would have enough equipment with sufficiently large specs just laying around in case of an emergency like this, especially on such a large scale (recall we're talking about airlifting truck-sized loads, possibly numbering in the hundreds or even thousands), and it's not clear to me what kinds of forces the choppers are designed to withstand, especially if we consider lateral forces due to wind or container geometry or whatever.
I mean, heavy-lifting choppers are something that I'd also expect the average NATO or (former) Warsaw Pact nation to have, and it's arguably in their best interests to make sure a key shipping route is operational (and in Egypt's best interests to accept any help possible).
Hell, Israel's close by, and I'm pretty sure they've got this sort of airpower in droves and are probably pretty heavily reliant on the Suez Canal; maybe instead of fighting with Egypt the Israelis could, say, pitch in and foster some good will? And further, it'll make up for the time when fighting between the two countries caused a Suez Canal blockage ;)
I am afraid you underestimate the weight of those TEUs and overestimate the capabilities of the Sikorsky CH-53 (which is what Israel has). That chopper has a max payload of 32000 lbs and a 40ft TEU has a max gross weight of 67500 lbs. Maybe you get lucky... but you'd need a lot of luck.
Also, if they find this is feasible, you don't necessarily need Israel to get a few Sikorsky choppers there, at least the Incirlik air base must have some and the Sikorsky definitely has the operational range to cross over there on its own, Iran certainly has some, the Eisenhower last I checked a few weeks ago was near Italy and surely that group has at least a few Sea Dragons...
> That chopper has a max payload of 32000 lbs and a 40ft TEU has a max gross weight of 67500 lbs. Maybe you get lucky... but you'd need a lot of luck.
1. This assumes that the containers are actually loaded to their maximum gross weight. That doesn't seem likely; you're much more likely to run out of volume first - even if you're deliberately "optimizing" for as much weight in those containers as possible.
1a. This assumes that the heavy containers are at the top rather than the bottom, which would be backwards from how containers are supposed to be stacked (or even allowed to be stacked per your average safety guidelines around center of mass, stack limits, etc.).
2. This assumes that multiple helicopters can't work in tandem (which they can, from what I understand).
So yeah, even if there are some containers that are too heavy to safely unload via helicopter, I strongly suspect that quite a few - most, probably - of those containers could be readily unloaded. And further, even if that ain't enough to get the ship moving again, it's at least a good start.
> the Eisenhower last I checked a few weeks ago was near Italy and surely that group has at least a few Sea Dragons...
> As far as I know, none of the helicopters mentioned above are rated for sling operations with 40ft containers.
There was a sea basing study and that only looked at 20ft containers and dismissed even a theoretical upgraded CH-53X (although of course the study was looking at much longer range than just lifting it and putting it back down) but again, that was just 20ft, these 40ft ones are just too heavy for choppers.
>
For many containers, using helicopters would probably mean at least partially unloading their cargo, which is a difficult and time-consuming endeavor. The process of removing containers by helicopters would be even more difficult, dangerous, and time-consuming, so it is very, very unlikely we will see it implemented unless the situation gets really desperate.
I mean, physical existence of a chopper vs its viability for this specific operation are very different things. Think of it this way: you may have a car, and you may even be familiar with installing and maneuvering a standard size tow. But that doesn't mean that I can just ask you out of the blue to come over and tow a prefab house that you've never handled before, then ask you to do it again a dozen times over (and on the double), and expect everything to go peachy.
Right, but in this context we're talking about countries with helicopters specifically intended to haul heavy things like shipping containers (and tanks, and trucks, and military base prefabs, and stuff). Keeping the analogy, it's like if you bought a Ford F-650 and your neighbors need help pulling some broken down semi (that's blocking the whole road) off the street in front of their house. And maybe you and your neighbor ain't on the best of terms, but you decide to at least offer to help anyway, because you need to use that street, too, and what was the point of buying that big pickup truck if you ain't gonna do truck stuff?
In this case, you're Israel, your neighbor's Egypt, the street is the Suez Canal, the semi is a giant container ship, and your F-650 is about 23 CH-53-derived heavy-lifting helicopters.
But do they actually routinely haul shipping containers packed to the brim? And continuously for days on end? There are various people in this thread saying that they can't, either because the specs are not up to par or because the stress risks rapid/early mechanical failure.
Also, while we're at it w/ terrible analogies, consider that many people (including the CEO of the company that got called to clean up this mess) are saying this is going to take weeks. The more accurate analogy is that your F-650 is a dozen tugboats, the truck is not blocking the road, but instead sunk in a marsh an hour away from town (the suez sand bank), loaded w/ 10,000 50lb lead anvils (the containers) and all the manpower you are able to summon in order to move those anvils are a dozen highly paid software engineers (the choppers) who may or may not be inclined to take a week off to help you move the anvils off the truck, and who may or may not be actually physically capable of helping even if they wanted to spend their week hauling hundreds of 50lb anvils by hand. Oh, and you can't just drop anvils in the marsh either, even by accident, due to the risk of poisoning the water supply for the town. And you can't rule out the risk of one of the software engineers tripping and drowning. And you're not even sure your F-650 can pull the truck out without tumbling it on its side or yanking off the front axle even if you empty it out completely.
Average expected teu is 30k lbs on a ship. A 20ft container is already close to the redline of these helicopters on the average. You cant max these vehicles for more than an hour or so without needing repairs. A 40ft container cant even be considered. Nearly all containers are packed to the brim to ink out max goods shipped. The whole chopper idea is just a movie fantasy for this. Real life is not pleasant to armchair theory.
Yeah, average. That doesn't mean that every container - or even most containers - are loaded to that weight per TEU. Indeed, it's highly likely that they're not; the heavy containers are going to be toward the bottom, and the lighter containers are going to be toward the top. And there are probably a lot more light containers than heavy ones, because...
> Nearly all containers are packed to the brim
Volumetrically, yes. Not necessarily in terms of weight. Indeed, unless you're shipping gold ingots or something, "max goods shipped" necessarily means that you're more likely to run into volumetric limits first.
Not to mention that the max container weight in practice is usually a fair bit lower than the ISO spec, since those containers have to get to their destination - which means traveling on roads and railways with their own weight limits (both for the whole vehicle and per-axle), and on vehicles that themselves are part of that limit (and themselves have limits of their own). And further, a container can only have so much weight stacked on top of it.
> Real life is not pleasant to armchair theory.
Indeed it is not, which is why when it comes to the containers themselves I'm speaking from experience as a professional in the supply chain / logistics field :)
(But yes, admittedly my knowledge on military helicopters is less substantial, so if there's someone who's not an armchair theorist on that topic who wants to chime in, that'd be most welcome)
I suspect something more like they drop the containers in the desert. The value of the goods is irrelevant in the face of cutting off Europe from Asia.
It seems that containers may be too heavy. The most powerful chopper (the M-26) lifts up to 20,000kg (with most heavy-lift choppers probably lifting about half that), while some containers may wel exceed 30,000kg.
Wikipedia says: As of 2016, the Mi-26 still holds the Fédération Aéronautique Internationale world record for the greatest mass lifted by a helicopter to 2,000 metres (6,562 ft) – 56,768.8 kilograms (125,000 lb) on a flight in 1982.
That is 56.8 to 62.5 tons, depending on the type of ton. Lift two containers at once.
Making things even easier, the shipping company knows the position and weight of every container. The containers have been carefully placed, keeping the weight low and spread evenly. The containers on top are the low-weight ones.
Two paragraphs earlier, Wikipedia states "the Mi-26 has a payload of up to 20 tonnes (44,000 lb)". Exceeding the documented maximum payload by almost a factor of 3 sounds like an excessive amount of overengineering, even by software standards. :-)
You're right that most of the heaviest containers would be at the bottom of the stack. That's kind of a mixed blessing though..
They went bankrupt, which is kinda sad. It had a designed lift capacity of 160t, so could theoretically lift several containers at once, given the right harness.
(Of course I have no idea if it would be have been practical to use it to unload the containers, but the idea is certainly intriguing).
The fundamental problem/flaw with that was when dropping off something you needed to somehow get a dummy load to not float away. (releasing the helium is not an option due to economical reasons)
Have you ever tried to stack containers before? Or had to airlift something via tow on a helicopter? You can do the latter (I watched it happen in the military), but the former isn’t happening from a helicopter, not into a floating barge anyway.
But the final goal is to put the containers back on the ship after it gets unstuck, no? I imagine the point of the containers being on the ship in the first place is that there are not enough trucks on land to get the containers off the desert to their destinations.
Right now the goal is to unblock the canal; if the entire cargo were lost in the process, that would be expensive, but I'm not confident it'd be more expensive than blocking shipping through for an extra fortnight.
It sounded like they were intended to drop them on land, where one would hope no ships would be hitting them. 'Lost' would be referring to the likely chance that once put on the desert they wouldn't be retrieved.
There are comments further down explaining how the containers likely weigh substantially more than the lift capacity of heavy lift helicopters. They'd have to partially unload the contents of each individual container first.
And if you're unloading, the human labor cost to unload the whole container is probably cheaper than the cost of running a fleet of helicopters for weeks to months.
The Skycrane helicopter that OP referred to is a true beast. It can lift heavy tanks and intact electricity towers. I won't be surprised if it gets used to lift the containers one-by-one.
Wow, the Chinook looks so tiny in comparison to the Mi-26.
40ft container maximum weight is 67,200 lbs. Skycrane max payload is 20,000 lbs and Mi-26 is 44,000 lbs. But do you think all the containers are at max weight? The ones on top are the lightest and the helicopters might be able to help with them after all, or maybe we can find a way to use two helicopters per container.
Can be heavier than that most won't be the max gross tonage. The biggest hurdle might be knowing which ones they can pick though. In not sure if the shipping company keeps the weights of every container on file somewhere.
It can lift at least 56.8 to 62.5 tons, depending on your definition of tons. The heavy containers have been placed on the bottom of the ship for better stability, leaving the lightest ones on top.
I like this scavengers idea. How far is it to Cairo, and what's unemployment like after Corona killed the tourism industy? Unlock all the containers, tell people you're paying them fifteen bucks an hour to come unload, AND they get to keep whatever they can carry off. How many people can you fit on that ship at once?
Or three per. Use a triangular spreader/yoke to keep them from having to pull laterally against (away from) each other. Single pivot point in the middle from which the load is suspended, allowing for imperfect coordination during hovering & movement. (The spreader can tilt or rotate.) Let a crawler crane and crew on the bank handle stacking/arrangement. Each container is lifted a second time into its temporary desert resting place. Has never been done before, just like space flight once. Would cost a lot and be dangerous, just like the military-industrial complex. Won't go perfectly, just like everything ever. Is inefficient, similar to but less so than losing the Suez Canal. Would take a long time, so start now. Really want to sarcastically thank all the naysayers and downvoters for policing all the dangerous creativity going on in this helicopter subthread. We must be more careful, especially considering how closely the shipping industry watches the Hacker News comments for ideas!
Yeah, i don't belive two pwe container is nearly enough. 3 or even 5 is a better idea smh, but you likely need 3 or 5 exceptionnal pilot who don't care if they die for science (and internationnal commerce).
All true, though I imagine the plan is unloading only some of the containers in conjunction with dredging, pumping out fuel, etc. Still huge scale, but I imagine getting just one of the ends out of the sand would open up more options.
Could you build a temporary barrier around the ship and the section of the canal, bring in some massive pumps, and temporarily raise the water level around the ship?
In the middle parts of the ship it is probably not grounded, so you might have ropes below the hull with large inflatable balloons on both sides below water level, to give the ship extra lift. Then on a high tide, with oil & water removed, maybe some dredging on the sides where it needs to rotate to, and.. go!
Lets say they cabled a Goodyear blimp to each side of the ship One Goodyear blimp is about 5,000 m^3 and a meter^3 of seawater is about a ton, so that gives us 10,000 tones of lifting force!.
The ship weighs 220,000 so it will be riding about 4.5% higher in the water. The main channel is very narrow. Its bow is buried about 20m deep and 100m into the shallow bottom outside of the channel. They are not going to lift it out.
Just so everyone is clear: The company that handled the salvaging of the Costa Concordia is the company that is handling the salvaging of this ship. Same exact people! You can bet that they are going to be doing the best thing that can be done.
Using the same Concordia techniques maybe SMIT Salvage would float Evergreen to 'loosen' it a bit out of sand, loosen further by dredging, and then when high tide comes [1], Evergreen would be able to turn around with help of tug boats.
i'd swear someone changed my comment but no it was me i'm an idiot. it's not even the other larry! sergey brin. sergey brin flies in with a zeppelin & floats the boat.
I've had the exact same idea but the canal bank is very shallow.. so you would have to build around the whole ship (as you said). This also seems like a major undertaking.
I am excited to see how they will solve the problem though!
If the bank is very shallow and mostly sand, maybe instead of building a damn all around the ship it would be easier to just dredge a new passage that goes around the stuck ship. After all the real problem isn't that the ship is run aground, it's that the canal is blocked for everyone else.
If would be a very long diversion. The turning radius of large ships is, well, astronomical, we're talking miles.
The canal itself is MASSIVE - 79ft deep and 700ft wide - and if you're turning you'd need to be wider still. We're talking about removing absolutely massive amounts of material.
> The turning radius of large ships is, well, astronomical, we're talking miles.
That's when under speed. If these ships don't have the unidirectional port engines like cruise ships do for maneuvering in tight spots (and they may not, I don't know), in this situation they would likely use tugboats for turning. That's what they're for.
That doesn't necessarily make a diversion feasible, but I don't think whether it's feasible or not rests on whether these ships can turn. That's really not the problem as I see it.
If with a zero turn radius, these ships are in excess of 1000ft long...you need a lot of clearance and a large radius just because of the physical dimensions (and so you know, we don't get a second ship wedged sideways in the canal.
We're talking about digging a diversionary channel. Making either end of that where it connects to the current channel wider to accommodate turning is trivial in comparison.
Probably very complicated since you couldn't have people in close. What if, as is not unlikely, part of the bank suddenly crumbles and the boat shifts?
Also, I doubt the sand goes down very deep...this is a costal area, not rolling dunes. You're going to hit rock quickly.
Interestingly enough, the Wikipedia page for this ship says it does have two 2500kW bow thrusters. I imagine if they were worth much in this situation we wouldn’t be talking about them, though.
which is not going to do much here. It seems the trouble with a lot of solutions - the tugs can probably tug with a force of something like 600 tons combined but the ship weights 220,000 tons which is like putting a force of 5kg on a 2 ton car which is stuck. Probably not going to budge it.
Really you want something which will shove it with a force maybe 10% of the weight, say 20,000 tons but there don't seem to be many of those lying around.
I wondered if they tied a cable from the ship to one of the other large ships nearby and fired up the main engines if that could do something?
> The turning radius of large ships is, well, astronomical, we're talking miles.
But do the ships actually have to turn? As long as they are floating instead of stuck in the sand, can't they be dragged sideways, either by tugboats or by stationary winches on land?
Of course, the ships would have to stop first, which would take miles of slowing down, and it would probably still be faster to fully dig the stuck ship out of the sand than to dig a diversion channel.
Well, they did it before, and without the help of the massive diggers we have currently, so it can’t be that hard, relatively speaking.
Besides, my newspaper said that the economic losses of the stuckness amount to like 400M per hour. That is a looot of money you can throw at a problem.
Actually with a well placed nuclear warhead placed directly under the ship, it could be thrown out of the canal and into the nearby desert clearing the canal route /s
Those were what, 300kiloton’s ish? So if we go to 1+ megaton we’d be good. Seems reasonable if we go up to 3-4 megatons, maybe we’d even end up with a big enough crater one of these ships could pull a three point turn next time?
A better way would be to explode one medium sized nuke under the ship, wait a few seconds then explode another and then start exploding nukes behind it until it's going fast enough.
Project Orion did contemplate a 400m diameter ship weighing 8 million tons....
>Proposed uses for nuclear explosives under Project Plowshare included widening the Panama Canal, constructing a new sea-level waterway through Nicaragua nicknamed the Pan-Atomic Canal, cutting paths through mountainous areas for highways, and connecting inland river systems.
Dredge a new passage? These ships do not turn on a dime, it would have to be started way before this blockage, and end way after the blockage so that the entry and exit are shallow enough of an angle for even the largest ships to handle with easy.
You're basically asking why can't they just make a whole new canal in less than a week?
I'd think that rather than dredge enough sand/dirt to create a completely new channel, it'd be easier to dredge out enough next to the ship to free it. They should only need to dredge out the bow and stern, the middle of the ship is already in deeper water.
No, just change the density. The oil industry uses cesium formate. It's relatively non-toxic. The brine can have density of 19.2 pounds per gallon. (2.3 grams/mL)
I honestly think a lot of thinking works that way, where we'll let tomorrow me worry about it. To be fair, a lot of the time it makes sense. The problems a solution creates are things we need to accept when alternative is worse (think global warming vs starvation circa 1770).
The pressure on the hypothetical levee wouldn't be much since we're only talking about a couple dozen feet of water depth. (Yes, some jerk is going to come along and calculate out that that's an impressive amount of total force and act like that's a big deal but it's not really that impressive when you've got a huge amount of material to spread it out over).
Digging out around the ship is going to be much less work because of the amount of material you'll need to move and how far you'll need to move it.
A dual approach might be to dig around, but just place the dirt in preparation for a temporary levy scenario.
So much cash burned per hour, a fallback wouldn't hurt, and secondary backhoes could be used, so the primaries don't slow down in their primary task, dredging.
Of course, I bet someone is, even now, trying to reduce costs, not caring that even an hour or two will wipe out all savings.
> Look at some of the photos of the front of it. Look at how far out of the water it is sitting. The ship might look like that if it were totally empty, but not when it is full of containers like this.
One thing many people are missing is the Suez Canal is not concrete, it’s sand, so the canal “walls” are not vertical they’re a relatively gentle 3:1 slope (4:1 in wider areas). Meaning only the center half of the canal is flat and “at depth”, the ship started hitting sand 30-40m from the edge of the canal. By the time it reached the visible edge it’s half-sitting on sand half wedged into it.
There is high tide in canal till next Thursday. It is the best window moving the ship. Once low tide, it will be much more difficult to unstuck the ship and move.
>Some people have suggested unloading the ship. I don't think you realize the infrastructure required to unload a ship. You're basically asking to build a port in the middle of the egyptian desert. That isn't going to happen.
I say build a trebuchet on deck and start launching containers into the desert.
It has a max capacity of 20 thousand TEU, which is "20 foot equivalents". Most of the containers on the ship appear to be 40 foot ones. So 10,000 is probably closer to the total number.
Edit: It may also not be "full". Here's a top/bottom picture with the most "full" I could find on the top, and the current situation on the bottom. https://imgur.com/a/b8neNkR
Edit: So maybe 6000 40 foot containers, current state?
In the photo where it looks quite full, the visible edge containers appear to be about 10x24x28 or 6,720 not accounting for missing ones on the top layers. In a photo from today it looked closer to only 6,000. Of course this methodology may be flawed or have some bad assumptions. Like containers below the visible deck layer??!
How do they load and unload these things in a port in only a couple of days?! Do the cranes take off several containers at a time? It's hard for me to imagine they can move a container off the ship and get back to another container in less than a minute.
The cranes take one container off at a time (except when the container underneath sticks to the top one, which is not good). Actually, wikipedia says some cranes do two to four containers on purpose now.
Usually the crane operator will load/unload several containers without moving along the dock; because they're all lined up, the crane only needs to travel in two dimensions (vertically and across the boat from port to starboard). The cranes are specialized to pick up containers by the top corners, which makes connecting fast. Standardized containers means the corners are at the same place (ok, there's a few sizes, but 40 ft containers are the vast majority of ocean shipping) and lining up is easy. On the dockside, there's a crew of longshoremen that move chassis (trailers) into place for the crane to drop (gently, usually) the containers on, those are then parked nearby, etc.
Depending on the ship (and the dockside staffing), you can have multiple cranes working the ship. Planning is required to keep the ship balanced and minimize the number of containers moved. These ships generally visit several ports in order, and usually both unload and load at all of them, so it's complex.
Depending on the traffic (and pandemics), the port runs up to three shifts.
And they are unloaded onto something that can transport them out of the way. Even in the desert, after 3,000 or so containers, finding room in the big pile to unload number 3,001 without moving the crane to make a new pile might be problematic.
Yeah, and those systems are fully automated too - years if not decades before e.g. Amazon started doing something similar in their warehouses. Mind you, containers were standardized in the 60's so there's a bit of a head start there.
Empty weight of a 40ft ISO is around 3,700kg
Max weight of a container loaded is around 30,000kg
Max payload of a Chinook around 11,000 kg near sea level at not high temp. (correct my number here from the wrong version of the Chinook...older versions were 4,500kg)
Two CH-53E Super Stallions should be able to handle such a container, then (max external payload capacity is about 16,000kg). Any American aircraft carriers nearby?
And this assumes that the containers are indeed loaded to their full weight capacity.
I should’ve been more clear. The helicopters could be 100 feet apart. Each helicopter would hook on to the corner of each container, and pull away diagonally.
The lift capability of this setup is from the y axis. But at a reduced load. This is a physics problem.
There are between 6 000 to 20 000 containers on this ship.
Thou reduce weight any meaningful amount you would need to remove hundreds or even thousands of containers.
I am not even sure if anyone would be willing to fly 4 helicopters tethered to each other, but even if they do, its going to be very slow for safety reasons.
And good like finding insurance company that is willing to cover, if anything goes wrong.
And enough pilots and helicopters, to do that 24/7 for a few months
This thing could have 20,000 containers on it. Thankfully it’s a 3rd of a mile long, so maybe you could offload 2 at a time, one helicopter on either end. At 1 container every 5 minutes....working 24 hours per day....that’s 70 days of work.
As this thread turned into 'post your crazy idea and get told why it would not work' here is my take: use powerful water pumps and direct streams of water to flush out the sand in spots where the ship rests on it and also around the bow.
That's very likely to be used, probably in conjunction with the suction dredge already brought in. Using compressed air or water to push around the sand you want to dredge is quite common. Sometimes ships have been un-stuck from mud by injecting compressed air near the hull to break them free of suction.
As a salvage job, this isn't that bad. No waves, a good climate, easy land and water access, hull intact, on an even keel, no leaks. It's just big.
If you want to waste time on this, look up the AIS data for all the big dredges and cranes Boskalis and Smit own, and see what's moving towards the Med. Here's the Boskalis dredger fleet.[1] If those guys decide to move sand, sand will be moved.
Smit's ships include the Smit Borneo, which is a crane ship big enough to take containers off a large container ship. It's done that before.[2] If
they have to partially unload the ship in place, it can be done. Not all that fast, but it will get done.
Here's a Smit container removal job from a smaller ship, but one in much worse condition.[3]
Those guys do a lot of planning and modeling first. The idea is not to make things worse.
That's probably what they will end up using, it's also the most compact thing they can bring to the site in short order. I mean companies like Boskalis and Mammoet have massive seaborne cranes, but it'll take a while for them to get there - I'm sure they're already on the way as well, in case the other solutions don't work or are late.
That's actually even a technique that has been used in these places in the past - Egypt used it when attacking Israeli fortifications on one of the banks during one of the conflicts in the past, just washed them away so they could cross with less resistance.
If you unload 20,000 TEU's onto rail cars it takes 5000 cars, double-stacked. That's 50 100-car trains. It'll take weeks to months to load and unload all that, if a proper rail depot is available to take it. It takes huge cranes to reach across a megaship and into its hold. That'd have to be build. On sand.
The idea that there's any quick way to manage the cargo of this ship is whistling in the dark.
I agree with your reasoning here. I'm genuinely interested in your interpretation of the idiom, "whistling in the dark".
I have heard this as, "whistling in the wind", taken to imply sound waves are distorted by wind patterns since sound waves use air molecules for conveyance. Whistling into the wind would tend to dampen sound waves intended for up-wind listners. Whereas, whistling with the wind tends to cause a whistle with the same decibel level as the into-the-wind variety to travel a bit further to down-wind listners.
How would the medium of light impact travel distance of sound waves? Or is there a cultural reference here that is different for me as a American english speaker?
Two different idioms, both fairly widely used (not sure about US vs non-US, but I've heard both as a non-American).
'Whistling in the wind' is about futility. A whistle is inaudible in the face of a massive elemental force like wind. "The lone excavator pushed on the hull of the colossal container ship, but it was whistling in the wind."
'Whistling in the dark' is about presenting a brave face in an intimidating situation: a nonchalant whistle in fear-inducing darkness. "They confidently claimed the ship would be moved in two days, I knew they were whistling in the dark."
If you care about understanding people and being understood, simply looking up idioms is way more effective than trying to construct meaning from physical principles. Just a thought :)
After you hit the limit of the crane reach, where does the next one go? Stacking on unstable sand seems a bad choice. So maybe 10% can be unloaded and just set on the ground. After that, they have to be moved somewhere.
The pictures I've seen completely hide the ship's bulbous bow. It juts out seemingly like 50 feet from the front of the bow that you can see. It looks like all of that is wedged in the sand
Ships have watertight bulkheads behind the bow in case they run into something. The ship can definitely sail without the bow. They should just cut it off and leave it there as a reminder to others not to f* up.
Only about the center third of the channel is actually deep enough for this massive ship. Both ends of the ship is stuck in several meters of sand. So far they've only managed get two bulldozers on to try and dig it out but progress is slow.
Those excavators are there for show while they try to figure out what to do. There is absolutely no chance that 2 guys with excavators are going to dredge out enough of the canal to free the ship, and the canal authorities know this.
It there was even shadow of a chance that that might work, then every single excavator in Northern Africa would be on it's way to the canal to dig it out and free the ship.
In fact I'd say that if there was even a snowball's chance in hell that that would work, China would be airdropping excavators into the area as we speak.
> In fact I'd say that if there was even a snowball's chance in hell that that would work
Damn straight, considering the law of salvage[1]:
> The law of salvage is a principle of maritime law whereby any person who helps recover another person's ship or cargo in peril at sea is entitled to a reward commensurate with the value of the property salved.
>Thus, if the ship was not a under command, unable to navigate or to reach port unaided, the service will be considered salvage even though the ship was not in imminent danger of destruction.
>It was in the light of this that Gilmore posits that releasing a ship that has run aground or on reefs, breaching a ship to keep her from running on rock, raising a sunken vessel, putting out a fire, and recapture of a ship taken by pirates, are all salvage acts.
The maritime salvor as a volunteer adventurer, Nzeribe Ejimnkeonye Abangwu, International Journal of Law, Volume 3; Issue 5; September 2017
Well, the law of salvage wouldn't apply since there's no "peril at sea" involved - the ship and its crew and its cargo are in no imminent danger. They are stuck, but there's no damage or destruction expected to them that would justify salvage. Losses by ship inactivity or blocking the channel are out of scope for salvage, since these are costs to someone else, and salvage law applies when you rescue the property of the ship owner/operator, it refers only to value of ship and cargo and (recently) environmental damage like oil spills (if it would be the liability of the ship operator).
Commensurate means proportionate, not equivalent. A $100 reward for rescuing a $100 billion ship is not commensurate, and neither is a $100 billion reward.
Oh it gets better, they could declare General Average https://en.wikipedia.org/wiki/General_average and then instead of buying new one of what you lost you are chipping in for everyone else on board.
Kind of amazing that in 48 hours, an event happens that threatens one of Egypts major income streams and political power sources, and the maximum they can spare is 2 bulldozers...
Like why not call in the army, rent every bulldozer in the district, and within 12 hours you'll have 30 on site and be able to move a lot of sand quickly to free it?
> Like why not call in the army, rent every bulldozer in the district, and within 12 hours you'll have 30 on site and be able to move a lot of sand quickly to free it?
Because that would all be a tremendous waste of money, and would not get the ship any closer to being free.
That’s not fairness. Chinese expatriates bought up a lot of the world’s stock of masks early on when the pandemic was limited to China. Also, ventilator shortages ended up not being a thing. Keep up. The world is not as simple as “America bad.”
Why? Out of malice and ignorance? No other country in the world ramped up masks immediately. People put too much stock in the presidency, a position held for 8 years max, and too little stock in the massive systems decades, or hundreds+ years old with incredible inertia that are really responsible for 90% of what happens in the world.
Turns out blanketing the population with surgical masks, which are designed to block the sputum coughed into the air by a sick person, is an effective tactic against a respiratory disease!
Sure, and at this same time Europe still hadn’t, Nancy Pelosi was telling everyone to come party with her in SF Chinatown, Biden was still running campaign events, and the CDC was saying masks are ineffective.
Most people didn’t realize how bad covid was going to get, even the experts.
Nope, only Germany had the fiber machines, the reason they take a year to build is the global supply chain is so distributed, and you have to build many parts in series.
It's almost been a year and I don't see an end for masks in sight (even with vaccines). Anyone who didn't put money into more production of masks is just greedy. It certainly wasn't a matter of time.
They are, it just takes a year or so to build these mech/chem tech ology machines when the specialized work force is so small and the training takes so long for knowledge transfer... this flows all the way down to high purity polypropylene sourcing itself.
I'm no expert, but I think it makes a huge difference whether you're in a flimsy, wooden ship with even flimsier sails made of cloth, or in a 400m long, extremely massive steel vessel with a reliable internal combustion engine.
Vs. storms at sea it's not a major difference, and if anything the sail boat is in better shape. The real advantage is accurate weather reports to avoid the worst of it.
Why? That sounds implausible. Firstly, the larger a ship, the less affected it is by waves. Secondly, high winds will shred your sails, but without sails it's hard to maneuver .
Exactly. I'm guessing weeks rather than days, and maybe more than that.
The best I can come up with is heavy lift helicopters to at least remove the front most containers to relieve some of the pressure but even that would be an enormous operation.
Anything else would require major construction especially if it is to reach more than just the first four or five rows which is likely not going to be enough.
The helicopter itself is 30 tons, leaving you 30. But 60 is the max takeoff weight. The max weight it is actually designed to operate at when carrying the maximum load is about 55 tons. With 30 for the helicopter itself, that leaves 25 tons for the load.
A container can be up to 33 tons loaded, so the heaviest will be beyond that helicopter (at least of you don't want to push it past its safe limits).
I assume that the heaviest containers are on the bottom of the stack, and that most containers aren't near the limit, so it could probably unload a substantial number of them.
Not so sure about that collapse, the keel of the ship is currently supporting all of that weight and seems to be holding up just fine. It's essentially a suspension bridge at this point, but I agree that it is probably better to unload evenly, however, that will add another very substantial time penalty. If the ship would break (which I have no idea at what load imbalance that would happen) there would be a delay a lot longer so it may be worth it to play this extra safe. But there is a very large amount of pressure on the people there to get this resolved.
They hired a company specialized in this kind of stuff (Boskalis), but as their CEO mentioned of TV it depends on how stuck it is. If you're lucky, pumping out the fuel and ballast can make the ship light enough to drag it clear with tugboats. If that doesn't work, you might have to unload some, most or all of the 20k containers from the ship to make it light enough. It can be done, but depending on how much is required it'll take a few days to a week to get the required equipment all the way to Egypt.
The people who should be desperately trying to pay a lot of money to get the ship unstuck are maritime insurance underwriters. There is a lot of insurance against late delivery. Unless they have managed to figure out how this is an act of god, that is.
I think this is the hidden story here. Egypt doesn't have a particularly strong economy, its stock market (unlike the US) is 40% below 2018, it's currency fell more than 50% vs USD in 2016 and has only recovered a few percent, and it (like the US) appears to have significantly more debt than ever before. And the entire globe is still somewhat covid-depressed economically.
When governments, banks and major companies are highly leveraged, all it takes is temporary system shocks to collapse the whole thing. It's not just the lost canal revenue, it's tons of companies in the region that can't get their goods to international markets which slows capital flows, tax revenue, import/export tariffs, etc. Will be interesting to see the effects.
That's more than 5% of the total government revenue. It can definitively lead to instability in the currency because the government might be forced to print the deficit if it cannot secure funding through other means. The inflation rate is well above 2% which means that the government should cut spending and only put money into investments that net a return (cleaning up the canal nets a return).
Given that so many ships that are run by people who can afford $300k per trip, which could pay the annual salary for a team of analysts, it's amazing you're making this comment.
Even if you could unload a container per minute you could only unload less than 1000 containers per day (assuming it's too dangerous to work at night) so at least 3 weeks of continuous helicopter operations.
Yes, that's true. It still might be faster than other options. You wouldn't likely need to unload the whole thing though, just lighten it enough to get it unstuck.
Doubt that's the case. The weight on it currently forced it deep enough into the sand. Just unloading half of it won't make it magically raise from the sands. The analogy here would be like saying pumping out Whale's stomach will make it possible to drag him back deep into the ocean.
Even though the vessel sits on sand, it still displaces a lot of water, which reduces the force of it sitting on the sand by a lot. Removing cargo, fuel, and dredging reduces it yet more.
Its most likely irrelevant. The reason why you see front so high up is because all the vessel's weight forced and smashed itself against the shallow water. At this point, rather than not the fuselage is damaged, and attempt to "ease up" the weight could only make it worse. I have been working enough around cargo vessels and at this size its never "oh he hit something, just put in reverse and you good to go". Similar if you ever get stabbed with a knife - hope never - but if you will, do not attempt to remove it on your own - you need to see a specialist who knows how to remove object it without causing internal bleeding, etc.
This vessel is most likely trash at this point. Time is of essence because tidal is pushing it against shallows and since its not perfectly centered it will eventually tip and with these amount of weight, not much tipping required for the whole thing to snawball. At this time they are figuring out how to quickly remove (save) as many containers as possible. Most likely will happen with another of these monsters to "park" close by and one by one will move the most expensive cargo first.
Another option I got from my buddy who is doing this stuff for life, is suggestion to dig up a whole big enough underneath to actually sunk the whole thing. This can be done in less than one week and is fastest most "stable" option. At this point they are not looking at saving this one vessel, but rather how to get the canal to operate again asap. You probably know it from driving on highway "move aside accident vehicles" is the most important thing to do.
You can see from pictures that most of the containers are 40 foot ones. Also, the ship doesn't appear to be at full capacity to me. See https://imgur.com/a/b8neNkR (top is as full a picture as I could find, bottom is current). My guess is ~6000 40 foot containers in its current state.
Is there a reason they couldn't have a smaller crane on board and dump them over the side. Surely even losing the cargo would be cheaper than keeping it blocked at this point?
Yes - that's kind of what I had in mind when I first suggested it. When containers fall of ships they often wash ashore on the UK coast. Even a container of motorbikes arrived in Cornwall recently... I'm presuming that only happens because they have some natural bouyancy.
If they don't tear when they hit the water (the metal is pretty thin) they should float shouldn't they? At 77 cubic meters and 30 tonnes their density is low enough, and they're generally watertight aren't they?
I think you're severely overestimating the depth of the canal. I'm too lazy to look up the depth of the specific section where it's stuck, but some sections are just 20 something meters deep.
In other words, just deep enough for ships to come through with little wiggle room. Not as tight as the Panama Canal, but it's not much bigger.
Depending on the design and bulk heads ripping a hole in the hull can be an option. My father was a naval architect and did some work re-floating container ships and I know they did this on at least one occasion and got the ship up the west coast of Africa, past Spain and Portugal, and through the English Channel. They would have stopped earlier but the ship yards en route jacked up their prices because they assumed there was no other choice.
The interesting thing for me is going to be where that ship goes if they manage to re-float it.
And yeah, even completely empty with no fuel or ballast you will never see the bow out of the water like that. However it is more than capable of surviving being dragged along sand. It's just that they have nothing strong enough to drag it with.
Eventually someone will stake some anchors into the ground and use an industrial winch, but that's where hull design starts to suck - there's no good anchor points by which to pull it, so there'll need to be a large number of straps cradling the hull that are being pulled.
This was my though, winchers/dozers etc pulling back the angle it went in on a high tide. Of all the solutions suggested this seems the simplest and easiest materials.
For anchor points they could easily weld additional steel plates/rings at numerous points on the hull for a many lines spread out.
Maybe place some cables under the front section attached to airbags. It would not lift it off the sand but may help with downward pressure on the pull back + the excavator work.
Also cant you vibrate/aerate sand to make it have a liquid effect? Might help pressure but no idea how that could be done at scale required... winches and cable seems easy to access fast.
-- the Ever Given has a mass of ~220,000 tons (2.2e8 kg)
-- let us very conservatively assume that it is a homogeneous block, 1/3rd of which is on sand, 2/3rds of which is on water
-- the Coulomb coefficient of friction for steel on sand is a very complex function of sand composition and size, but roughly it's about µ=0.5 and F=µR [1]
-- For the 2/3rds of the ship that are in the water assume that it moves frictionlessly in an inviscid liquid (not true at all else ships wouldn't have huge engines!)
-- You therefore need to apply a net tension of ≥0.3 x 0.5 x 2.2e8 ≈ 33 MN to a wire to have a remote chance in hell of accelerating the ship backwards
-- This is about twice the thrust of a Space Shuttle solid rocket booster at liftoff.
The weight on sand equals the weight of the portion of the ship that has been raised above sea level by the collision. The bow appears to have been raised, but not the stern. The lift is by about 10% of the ships height (or less), so 5% on the average of the ships length. That cuts the above estimate by a factor of 6. The remaining required force could be provided by a number of winches of a pull of 1000 tons each operating from the opposite bank of the canal and pulling in the direction opposite to the ship. Tugs would then have to turn the ship straight as soon as it starts getting afloat.
You would probably need to be the US military. Once you have a setup onsite; helicopters, pilots, fuel, maintenance, crew to rig containers, you could rapidly unload the containers. Check out this video: https://www.youtube.com/watch?v=08K_aEajzNA
US Military is probably the only entity that could pull this off in a timely manner. At great cost of course...
Looks like your right. The US has:
https://en.wikipedia.org/wiki/Sikorsky_CH-53E_Super_Stallion... as its near equivalent with a external payload of 36,000 lb. The Russian helicopter carries 8000lbs more at 44,000lb, though Wikipedia doesn't say if this is an external or internal payload.
Looks like a 40ft shipping container weights around 8000lbs empty, couldn't find a stat on full. It seems such an operation would be outside the capacity of these helicopters. Sure they could comfortably lift empty containers, but probably not full ones.
>Some people have suggested unloading the ship. I don't think you realize the infrastructure required to unload a ship. You're basically asking to build a port in the middle of the egyptian desert. That isn't going to happen.
"Some people have suggested unloading the ship. I don't think you realize the infrastructure required to unload a ship."
I would guess someone could figure out how to use a normal-ish crane to unload some of the containers and set them down in the sand. The top containers look like they are maybe 150 feet or so higher than ground level.
How about creating a mini-dam surrounding the vessel and raising the water level so it can turn.
Or stopping the current at 90% of the ship and letting it push to the front ( if it's in the right direction), perhaps in combination with gigantic sails ( if there's enough wind) and/or sucking sand/mud from the bottom.
What if we could part the water at both sides of the ship? Would that suffice as makeshift gates?
The Egyptians had a bad experience with that in the past though and lost a lot of gear and many men in an incident. Might be understandable if they didn’t want to do that again.
The canal is 200 metres wide, 25ish metres deep. Gotta think in the cube, because now you're talking volume. I have zero idea what thickness you're going to need for your dam, but I'm going to spitball and say 10 metres at the top, and 30 metres at the bottom to get a slope like you'd see on something like the Hoover Dam.
This means you need to provide .. lets see, a trapezoidal cross section is 500 square metres.. 100,000 cubic metres of filler. Twice. And then you probably need to curve it to resist the pressure, so that's a bit of a lowball figure. You can't dam any less, because the ship is stuck sideways across the canal.
Using some old numbers for concrete pours in Ireland (2016 era) per cubic metre, that's 7.5 million Euro worth of concrete. Sure, you're not going to use pure concrete like that though - you'd probably start dropping massive boulders in first, and then try to cap/fill it.
160 km of protection against 2m. High waves to build something on unstable soil isn't exactly the same thing as this, is it.
They need some construction which they can add water faster than it escapes the container, to raise the water level.
If stacked water based cofferdams would be a solution ( idk depending on these requirements, current, ..), it could be done quickly if they have the bags ( multiple teams, multiple locations to start and filling the coffers with water as soon as possible). The budget to fix this fast is probably pretty high. A lot would depend on how much they need to raise the water for the pressure, so it wouldn't collapse. ( Fyi, i do think water based coffers would collapse, but perhaps sand ones can be placed in top on it for 1 meter).
Palm islands needed a construction that holds multiple years and isn't the same as the issue in the Suez canal.
Tu be honest, I'm just thinkering about the variables that could make this work, instead of dismissing it immediately.
> Using some old numbers for concrete pours in Ireland (2016 era) per cubic metre, that's 7.5 million Euro worth of concrete.
A sister comment mentioned 400$ million per hour worth of trades being blocked by this, so the cost of this would probably recouped by the time the order is cleared.
Not all. But there are late fees, refunds, profits lost because your ship now has to travel a larger route and can therefore take fewer roubdtrips, increasing costs per roundtrip due to the longer route etc.. If we just assume a meager 1% actual loss, the concrete would be worth it in two hours. Even with the remaining expenses due to work, this should pay for itself rather quickly.
Biggest issues seem to be building ( and logistics) + deconstructing. But i saw an estimate of a cofferdam for a
bridge of 640 meters ( but less deep and with a single crane) of 16 days.
They need to give that canal some serious laxatives to flush that ship out. ;-]
But seriously, it looks like dredging or a king tide will be needed to get that ship flushed out of there.
Btw, it takes roughly 9-10 additional days to navigate a ship around the horn so ships would be better off steaming the long way around if time is critical.
Lloyd's List estimated that every day Suez is closed costs US$9 billion ($400 million per hour).
If it could be done technically and open up the canal, it would be cheaper for insurance companies to buy the ship, it's cargo, buy all nearby property and then blow the whole ship up.
That figure is for the value of goods that traverse the canal, not the closed cost. The canal generated 5.61 billion USD in 2020 [0] so it is costing them 15 million dollars a day in lost revenue.
For the shipping companies, they can still go around Africa and the cost of doing that is probably only a little higher than paying the toll as Egypt wants to extract as much money as they can without pricing it over the cost of going around Africa otherwise the shipping companies would just do that in the first place.
You get two aircraft carriers ramming each end from different sides. Then if the aircraft carriers get stuck on the bank, ships can still pass in-between them.
Ironically, the blast radius of that thing is still smaller than the ship that would need to be blown up. If you really want to clear the canal with an explosion, it would have to be one large enough to vaporize the ship, making sure there's no debris in the canal afterwards.
How many tons of explosives would be required to "bomb it to smithereens" without leaving wreckage that blocks the canal? Please calculate and show your work.
> Look at some of the photos of the front of it. Look at how far out of the water it is sitting.
I'm curious how much of this is hightide vs low. If the photo is taken at low tide you have about 1.7m drop on the stern which is going to make it look far more stuck. While if the photo is at high tide, wow.
> And what happens when that causes you to rip a hole into the hull of the ship?
I cant see sand friction ripping a hole in the steel unless there are rocks in the mix. I think the bigger risk is cracking the hull if there is too much weight at the front vs displacing this across the entire hull.
> I don't think you realize the infrastructure required to unload a ship.
To this, while absolutely it huge infrastructure Im assuming they only intends to reduce weight, not unload. So some crane choppers or whatever can make a big difference taking off 5% of containers type thing. I even wonder if they want to keep the back loaded to effectively life the front... but that might exacerbate the risk of hull breakage?
> It's really stuck. It's probably going to take a couple of weeks to get it unstuck.
My armchair engineering would dump a load of salt into the water to increase buoyancy of the ship long enough for the tugs to get some momentum with less effort than currently.
That would be my cheap try solution to help the tugs that have already hit there limit so why not change the physics and add a load of salt.
You could increase the buoyancy by something like 230 kilograms per cubic meter if you fully saturate it on a hot day, but I suppose you'd have to dam up both sides to keep the brine from washing away.
At this scale, even air pressure would be a factor, I'd presume a higher air pressure would be more conducive as large surface area of the water than the ship, though might be wrong.
Assuming you narrowly dam up the canal near the ship to contain the brine, no I don't think so. Seawater is 3% saline and saturated brine is 26% saline, so you'd probably have sufficient mixing within the canal itself once you open the dams. The canal is 120 miles long and I can't imagine you'd dam up more than a third of a mile at maximum. But it would take a whole hell of a lot of salt.
Yes since the salinity transfer from the canal into the Mediterranean Sea is already enough to make species from the Red Sea colonize the east Mediterranean. The Aswan dam reduced further the amount of freshwater coming to the area. So I would guess adding more salt wouldn’t be too good for the eastern Mediterranean.
And how much salt would you need? At least 100kg per m3. Assuming the canal is 250m wide you need a 400m section dammed and average depth is 15m then you need 150 thousand tonnes of salt. Thankfully Egypt produces more than 3 million tonnes of salt per year so just a few weeks worth of production and enough to fill a large bulk carrier ship.
I was thinking a few lorry loads on the edge they are trying to pull, just to give it a kick briefly so the tugs can get that initial momentum going. More of a brief sudden kick/change to give it that edge.
With that I don't think with the whole damming of aspect would be any better than damming of and pumping water in. Also with that scale you run the risk when you breach the dam of causing what I'd call a saline tsuanmi which might not work well for the ships in it's path and may well cause another to get stuck.
So, more a form of quick kick to aid in getting the tugs an initial bite and a quick dislodge, however small, would only help and may well tip the balance.
The ship weighs roughly 100,000 tons. I very large lorry might be five tons. Factor in the static friction of the ship's keel stuck in mud, and the suction opposing any movement.
For kick of initial momentum, I suggest nuclear weapons.
You could unload it using crane ships, and just leave the containers in heaps on the bank of the river, but it could take weeks because that thing is filled to the brink. Any way you look at it there's not an easy solution in sight.
Though, to be fair, even the CEO of Flexport initially dismissed this, saying "I assume they'll have it fixed in a day or two. And anyways there's such a backlog of ships waiting to unload at the ports of arrival that it probably won't even impact the transit times of the cargo."
https://twitter.com/typesfast/status/1374501965418352640
Unloading it may be exactly what happens (based on comments from the Dutch salvage company brought in to deal with the mess). And yeah, it's going to take weeks (best case scenario).
I'm not familiar with shipping, but I would guess there are some type of crane ships which could be dispatched along with barges to slowly offload some of the container. Obviously it is going to take some time mustering all these specialized craft and specialists on location.
What's with the many joucular/tounge-in-cheek posts on this thread..
In an emergency situation like this: could they not use helicopters to lift containers off of the ship and just stack them next to the canal until they've freed the ship?
Seems pretty quick to setup and do assuming there are helicopters that can move that weight.
Crazy idea : Can we roll it into the water by pulling it over high strength rollers of some sort ?
It would be pretty cool to use the same technique that was use to build the pyramids.
The ship is 400 metres / 0.25 of a mile long. With containers, it weighs anywhere up to 199 thousand tons. One does not simply attach a few hundred cables, put some rollers under it, and pull with all the tractors you can find in Egypt.
Also, it's already in the water. It's just turned sideways and buried the bulb (by the looks) into the canal wall.
I’m thinking a complex series of pulleys and chains set up and attached to the Great Pyramids of Giza and then like a tooth tied to a string and door - attach the chains to some of Elon’s rockets and pull that ship loose.
At the level of [un]reality in many of the comments under OP, actually the Great Pyramids were built off-site and then dragged to their present locations.
Somebody call Elon. Get the TBMs, and set them to work building a tunnel under the ship.
Now fill the tunnel with giant rubber bladders.
Call the Saudis and have them start shipping over helium. Fill the bladders with helium.
Okay, keep the saudis around and get them to bring over one of the high pressure water drilling rigs that they use for oil. Start digging out the sand above the bladders, and float them up to be UNDER the ship.
Okay now call the Dutch. Get them to bring over some MASSIVE water pumps and some damming equipment. The two guys on excavators can help. Dam up the canal on both sides of the ship, and pump out all the water.
The bladders become rollers. Roll that ship back into the middle of the canal.
Okay now repump the canal, and float the ship away. Bam. Done!
>Some people saying: just drag it off of the sand. Okay! And what happens when that causes you to rip a hole into the hull of the ship? Now it's really stuck.
Not just that, but don't forget the inertia. The moment the ship gets unstuck the force needed to get it moving, multiplied with the ship's huge mass would create such a huge momentum that it would be very hard to stop it from hitting the other shore with the stern.
There are 20,000 containers on the ship. Assuming you needed to remove 1/4 of those containers to get it to rise far enough to get off of the sand, you need to move 5000 containers.
Assume that it takes 5 minute to connect a bridle to a container, hook it to a helicopter, and move it...and then also assume that the helicopters can run 24/7 and never have to refuel, that they can hot swap in pilots, and that there is never a single problem, you're talking about 25000 minutes, or about 17 days of absolutely non stop running helicopters.
And that only gets you 1/4 of the containers, and it might not even work at all.
(It's not a dumb question, and I'm sure that it was already discussed by the team who is dealing with this. It's just that the scale of what is happening here is restrictive.)
Just a small correction: 20.000 TEU is not the same as the amount of containers. TEU is the number of twenty foot equivalent. There will be enough 40 foot containers on there. If it was going to Europe there will hardly be any empty containers.
Amount of actual containers is probably the 20.000 divided by 1.6 or so, though it's not a given that any vessel is fully loaded to max capacity. Sometimes need to deal with restrictions.
We really are bad at dealing with large numbers. 20 000 does not seem that much when it’s just written that way. Even looking at the pictures, this is a lot of containers, but the efforts needed to get them out of that ship are hard to imagine.
It appears to be roughly 7 x 20 x 25 containers, or 3500... (height x width x length.)
EDIT: Freezing this video I got a better view of how it's stacked today. I'm sure this is imperfect, like I said trying to count candy in a jar. But I'm curious what the real number of containers is!
Your height number is off by a factor of 2; a significant factor of container storage on these large container ships is below the deck. It isn't uncommon for these large ships to have 9 to 12 containers stacked on top of eachother before the stack reaches above the deck and becomes visible from the side.
Most heavy lift helicopters don't really go above 20 tons takeoff weight, while even a 20 foot container has a max allowable weight well above that. Most shipping containers will the 40 footers, so helicopters will probably be a no-go. There's also 20k of them so it would take quite a while.
That said, taking off some containers is a viable option but it'll probably have to wait for a crane ship to arrive.
Typically an empty 20 foot shipping container weighs between 1.8-2.2 metric tonnes (about 3,970 - 4,850 lb) and an empty 40 foot shipping container weighs 3.8 - 4.2 tonne (8,340 - 9,260 lb) depending on what kind of container it is. For example, high cube containers tend to be heavier.
Yes, especially with the container shortage[1] reported earlier this week, I would be very surprised if empty containers are being sent away from where there already is a shortage.
Based on the information on Wikipedia, it sounds like the ship could potentially hold more than 20,000 containers. Assuming I'm understanding the article correctly, that'd be a lot of containers to move 1-by-1.
It has 20,000 TEUs (twenty-foot-container-equivalent-units).
Weight-wise, the average container could be lifted with a military heavy lift helicopter: The ship carries 20,000 tons, i.e. 1 ton per TEU, and a CH-47F can lift 11 tons. Although a TEU can weigh up to 26 tons, so you couldn't lift the heaviest ones.
The problem is speed: A ship-to-shore crane at a properly equipped port can do a lift every 2 minutes. Ports can speed things up by lifting several TEUs in a single lift - but you'd also expect a helicopter to be slower, because we haven't put decades of optimisation into the process. So let's assume those cancel each other out.
If they can keep up that rate with a helicopter, and they operate 24 hours a day, it would take 28 days to unload the ship.
Outside of Vietnam war movies, it's very unusual to see helicopters flying in close proximity.
I suppose it's possible you could find a bunch of pilots confident in cargo handling, landing on ships, and close formation flight all at once. Or that the ship is large enough the helicopters would practically be independent of one another?
Removing 10% of containers by helicopter also would take unreasonable time, removing 1% of containers might be plausible but I don't think it would make enough of a difference to justify the risks.
it's a quarter mile long. You can probably have 10 helicopters working at once while still keeping safe distances.
Each helicopter has a crew of 4 on the boat and 4 on the shore. They hook 4 chains to the 4 corner hoists of each container. Say it takes 1 minutes per container to affix the chains, 1 minute to fly to the sand, 1 minute to unhitch, and 1 minute to fly back. Thats a lot slower than agricultural helicopters, but nobody will be very practiced with this yet, so it'll be slower.
The entire ship could be unloaded with this method in 5.5 days. Perhaps less if not all the cargo needs unloading.
You're joking, right? It's a quarter mile, or 400m long. Ten helicopters in it means ~40m distance. That's less than safe distance between cars in a highway.
The worlds highest capacity heavy lift chopper (M-26, of which there are 20 operational) has a max take off weight of 44k lbs. A standard 40 ft. container can be loaded to a gross weight of 66k lbs.
It takes a purpose built crane a few minutes to unload a container, so I sort of doubt a helicopter could make it happen faster.
Coincidentally a quarter of a mile (400m) is also the length of those oval tracks around soccer fields in Europe. we used to run on them a lot in PE back in high school.
Seems to have a max take off weight of 19 tons by the look of it. The heli itself weights about 9 of those tons already, which leaves 10 tons of leeway. Those containers, from what I've read around here, can be well above 30 tons each. So that sounds like a no go. Also, they built only 31 of those helis in total according to wikipedia.
It's a way of thinking out loud and providing an opening for someone more knowledgeable to explain what is being overlooked. It makes for interesting threads.
It's wedged at the stern because the bow impelled the ground. The stern isn't impelled, once the front of the ship is free, the back be easily ungrounded by tugs.
It's pretty great. I hope this serves as a lesson to some people
"If these jokers will talk this much about this even though they clearly know nothing at all about the tech involved, what does that say about their comments on all the other threads here?"
I feel like we need a "why don't you just?" safe word, where the intent is to signify "hey I'm not being a smartass, I'm really just curious about why this seemingly simple solution won't actually work".
So much of what happens on the internet is in bad faith that it makes it really hard to just have innocent conversations without being misunderstood. :-(
I try to replace any "I think..." and "Why don't they just..." comments with "I wonder if..." ones.
I've found it communicates my curiosity in a way that's less likely to be misinterpreted. It's made my internet/IRL conversations much more productive.
> So much of what happens on the internet is in bad faith
... and I have to admit I’m still not able to easily recognize the difference between bad faith and utter lack of experience and/or intelligence without digging deep into the history of the individual posting such “questions”.
And the need for that extra digging makes such questions effectively the same waste of time and emotional energy as responding to a troll.
Same. It's super easy to know when I am communicating in good faith, but it's not so trivial to know when you are.
You know those scenes in the movies where two characters circle around each other giving the side eye like "so are you fucking with me or are we cool?"
Twitter in particular feels like a whole site of people doing that. :)
Agreed. I’ve thought the same for posting an interesting fact. Anymore, I want to preface every single one by saying, “hey, you may already know this; I’m just sharing it because it hasn’t been mentioned yet and I think it’s neat. If you were implying the fact already, I apologize for overlooking that.”
What do you think people at "billion dollar companies" do in such situation?
Exactly the same thing. Just not on a public board. Just like everyone else is doing when discussing problems they face in any line of work.
Since it's unlikely anyone here has any decision making power relevant to the Suez canal, look at this discussion as an exercise in group problem solving. Sharpening the saw.
Not exactly-exactly. There are (e.g.) 1000 suggested solutions.
950/1000 of them are silly, stupid, impossible, -facepalm-, etc.
25/1000 are doable.
10/25 are doable and cost less than the other 25
5/10 are faster than others
2/5 are actively being investigated, and of course they won't be announced to 'us'. They (thinkers/engineers/specialists) will have to talk to their CEOs/COOs/CFOs, insurance companies, Egypt's military, handlersof the canal, and a bunch of other key stakeholders.
(my ratios are pure guesstimates, but it makes sense that there is a selection process, and we won't figure them out from our couches)
Like the parent comment said, it’s a way of thinking out loud.
For e.g., when someone says “just dig it out, it just pull it away...”, I give them a benefit of doubt by assuming what they are really saying is “I know it’s not as simple as just pulling it out but can someone explain why we can’t though?”
> armchair engineers who think they're gonna solve this better than billion dollar companies
There are 2 types of armchair engineers.
The ones who sneer and say, "If they just <x> then it would be fixed because I know best" Those people are bores.
There are others who are just tossing ideas around: partly for amusement and partly because they enjoy thinking, "What would I do in this situation ...?"
I haven't seen too many bores in this thread.
I don't think this latter group _seriously_ thinks they know better than experts, and I have found the various ideas and counterarguments interesting to read.
We have the luxury of just throwing around ideas and not caring about the consequences (because nobody in power will read it). It's just fun to think about how you'd solve a problem like this.
For example I'd try to attach a two Raptor engines to the ship and blow it back to the water :)
Many likely problems: equipment avilability to do so, time it will take, debris falling off and from the operations, risk of capsizing, probably need to load pieces on barges/crane but canal is not much large
Detonate a small but still relatively powerful bomb upstream (or maybe multiple small but staggered ones), to create a small tsunami-like wave, which in turn will move at least the ship's aft/stern (as the ship creates in the canal a "V"-like shape which will therefore concentrate most of the wave's force in that area) when it hits it. Almost guaranteed to work, theoretically.
Just bring in a Bagger 288[1] and use it to excavate a new diversion canal in front of the ship long enough to get it out of the main canal, bada-bing bada-boom. Simple!
That beast is really outstanding and would probably be able to do the job in reasonable time. This machine is so insanely large, it would fit into any sci-fi movie. The craziest thing is, some years back it was driven over a distance of 22 kilometers cross country to a different site, which was just mindblowing.
Proposing ideas shouldn’t be taken as suggesting that the poster is confident the ideas are correct, but rather as an invitation to talk through whether it would work and maybe learn something interesting.
So you are complaining that on a startup forum people are trying to solve billion dollar questions?
Besides, billion dollar companies often miss things. Yes, they have the more relevant experts and much better data than we, but they have to content with internal and external politics and have fewer people throwing around ideas. Sometimes the answer is to "why haven't you done X" is simply "nobody with a voice to be heard had that idea". If billion dollar companies were the infallible giants you make them out to be then startups straight up couldn't work.
Yes, most here are armchair engineers, though quite a few actual engineers around, so you never know. But the embarassing point is: the billion dollar companies currently also don't seem to have an idea about the possible solution :p. I am pretty optimistic that they will come up with a reasonable plan soon, but there is a nonzero chance that someone here will come up with a good idea. Sometimes it quite helps to be at a distance.
I think there's still room for suggesting potential solutions that might work, even if they make the operation of the cargo ship (even more?) unprofitable for its owners.
That said, the ones mentioned there don't pass the smell test.
Well, there's always the option of just demolishing the ship and its cargo, getting everything out of the canal without worrying about whether any of it survives the process.
That would still be expensive, but is it more expensive than blocking the canal?
How do you destroy a 1300 ft ship with 20k+ TEUs of cargo on it? How do you then clean all of the debris out of a pretty narrow and shallow canal so that other ships can go through again?
I can't imagine that being a very quick thing to do.
I came to this purely to do a CTRL+F "explosion" and was dismayed to see all the comments proposing it voted down, whereas comments proposing things like balloons being used to lift the boat were not voted down.
Clearly demolition is one of the things to consider in this scenario, and is at least as realistic as the million-luftballons. It would also make for some fun conversation.
>How do you destroy a 1300 ft ship with 20k+ TEUs of cargo on it?
A smaller less stuck ship or barge you don't care very much about full of explosives.
And you don't need to destroy the whole thing, just shred and distribute the part that's in the canal enough that it's no longer an impediment to navigation. Sure you might be left with 30 big chunks but 30 big chunks can be picked up with conventional marine construction equipment. If the bulbous bow is still buried in the sand then whatever, you don't care.
We're talking about a Mont-Blanc sized explosion here. Definitively messy but with modern engineering I think you could whip up a directed blast that ensures the task is accomplished without unnecessarily digging a hole or some other dumb side effect.
It's still easier to dislodge a giant ship in one piece than it is to remove one giant ship's worth of random metal shrapnel from a narrow, shallow canal.
Who said anything about shrapnel? There's another comment in the thread making the case that "we don't want to just tug harder on the boat, because that might tear a hole in the hull". That could destroy the boat, but... so what?
Because if you destroy the boat and it sinks that will make the passage unusable for a long time? I mean currently it seems possible to drag the ship out of this problem but if it's no longer floating you might need to start sawing it into pieces like this example of the sunken Tricolor https://youtu.be/0ENOJBLVgjw . That will take months and will have a serious global economic impact.
Because then you'd still have to remove everything, but now you don't have one big, controllable system, but you have lots of pieces that will move in unpredictable ways.
The canal is shallow and narrow, and gravity isn't working in your favor here. A ship has a natural tendency to float (even if it currently isn't). Pieces of debris don't. You will have to remove all pieces that break off, one-by-one.
Because that would take months; they'd have to unload it, pump out the oil and fuel, get a disassembly crew and a ton of gear and all the infrastructure around it, etc.
You can't possibly have 10 helis safely unloading cargo at once from a single ship, that'd be an invitation for disaster. Also, doing that in the dark would simply not work. 10 sorties/hour is also unrealistic; with proper cranes and infrastructure at port it would take something like 10 minutes, with choppers it would take more time.
IMHO if helis would even work (which is debatable and debated here), the optimistic estimate is that you could unload something like 20 containers per hour, 300 containers per day, so 30 days for the cargo. It seems plausible that you can dredge the banks and drag the ship out much quicker than that.
>You can't possibly have 10 helis safely unloading cargo at once from a single ship
5 loading at a time, while the other 5 unloading on the ground - plenty of space as ship is 1300 feet long.
> doing that in the dark would simply not work
you flood the ship and the space around with light. Almost 30 years ago we did a night ship unload at an unprepared location - no issues.
>10 sorties/hour is also unrealistic
doing it with crane we did about 15+ - we weren't union operation though - we were paid for performance, not time :) and being young we were moving fast. With chopper not much different if weather is ok.
> 10 helis, 20tons each, 10 sorties/hour = 200k ton in 5 days.
Among the many problems with this calculation is that shipping containers can't be freely subdivided and recombined, and can have a loaded weight over 30 tons.
I mean, the 220,000 tons of debris are at least not a single solid object - so maybe they'd be moved by the current (if there is any) or could be pushed to the sides by smaller vessels. Then the actual cleanup can happen while the canal is already back in operation.
> the container ship __itself__ is the easiest way to move all of that debris out.
You'd need a nuclear-level explosion to blow this ship up into small, practically movable pieces that aren't connected anymore. Everything on that ship is steel. Conventional explosions would just blow a few holes in it, and deform everything enough that moving things becomes impossible.
Yup, I get it. The energy released by a thermobaric weapon is spread out over a very, very large distance. Inside the blast, people will be killed and equipment will be rendered interoperable by the extreme temperature and the over pressure. Outside the blast you have a very strong (but subsonic) blast wave. But inside the blast, the pressure will envelope stuff, and push on it from both sides. With regards to blasting away a very large ship, thermobaric weapons are not particularly effective.
I think you've overestimating how much stuff an explosion removes, as opposed to breaks. Explosions are very good at making a functional thing not function anymore, but they're not as good as you think they are at evacuating an area.
Look at the aftermath of the Beirut explosion. The metal frame of the building the explosion happened in is still lying there.
The blast radius of an explosion scales with the cube root of the energy of the explosion. So if you want to make the hole twice as big, you need eight times as much explosives. To create a hole the size of a large container ship, you'll need a nuke. A pretty big one too. The Ever Given is 400m long, the crater left by the Trinity test (22kt) was 390m across.
Because you still need to use the canal afterwards. And you need to convince the crews of the ships that the radiation won't be a problem. And the authorities of the ports they go to. And so on.
Look at some of the photos of the front of it. Look at how far out of the water it is sitting. The ship might look like that if it were totally empty, but not when it is full of containers like this.
Some people saying: just drag it off of the sand. Okay! And what happens when that causes you to rip a hole into the hull of the ship? Now it's really stuck.
Some people have suggested unloading the ship. I don't think you realize the infrastructure required to unload a ship. You're basically asking to build a port in the middle of the egyptian desert. That isn't going to happen.
It's really stuck. It's probably going to take a couple of weeks to get it unstuck.
