Is that ship still stuck?

Re: Is that ship still stuck?
#992Who designed this critical piece of infrastructure with a single point of failure?
It doesn't have "a single point of failure", it has infinite points of failure: Put a big ship on ground at any (infinitesimally adjacent, so infinite in number) point along the length of the canal, and it's blocked.
Re: Is that ship still stuck?
#993I wonder if they could build a dam around the ship and lift it with water.
Physically that would work, but this ship has a draught of 14.5 meters. You'd need to build a pretty high dam. It would need to cross the canal twice, as otherwise the water level inside the dam would never be higher than the current water level, and you'd need to pump in the water. Then, once the ship floats, you'd somehow need to move it out of your small artificial lake into the canal, and remove the dam you creat…
Two temporary dams across the canal, above and below the ship; basically creating a temporary lock in the canal. Sandbags and tarpaulin, or two huge balloons you fill with water so they squeeze themselves stuck against the sides. (In both cases, with suitable temporary support structures on the outer sides. For a base, use a big empty ship or three on each end, run them up against the dam and scuttle them, then refloat when all is done?) Then fill the lock you just built with water pumped in from the canal, and the ship should float. When it's upright in the middle of the canal, dismantle the lock again. It doesn't have to be all that super tight or anything; as long as your pumps can outrun the leakage, just keep running them for the duration.
The GP is only the second such suggestion I see here. The first was on the second sub-page of comments (close to a comment about lifting the ship with a hydrogen balloon, for a search term; combining them is where I got the water balloon idea in stead of sandbags). Mine would have been the third.
Quite honestly and seriously seems far from unfeasible. And perhaps, depending on how fast you can get enough sandbags (or just the bags; sand should be available nearby?), tarpaulins, and pumps there, faster than most other suggestions.

#994I 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 real…
> 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?

Oh look! Everyone in these comments was way off. They dredged some sand and dragged it off - after days, not weeks.
I now wonder how regularly Gell-Mann Amnesia occurs for people on HN, really.

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 l…
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…
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?

#997My prediction: The ship isn’t going anywhere. It will need to be disassembled.
Aaaand... that’s why nobody should heed my predictions...

Apparently it wasn’t that hard after all. HackerNews people are not shipping experts.

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…
It looks like the people that freed the ship yesterday were not that bad at estimating scale.
