What's interesting is that most people seem to expect that carrier to be on it's way within a day or two at best, my personal estimate is that this could take weeks to get resolved, if they decide to unload on the spot it might even take longer. This is not easy to fix at all.

Essentially they have one more shot at a quick fix: todays high tide. And if that doesn't do the trick they will have to come up with another solution but those will likely be much slower to put into effect, 224,000 tons (!) is a lot of mass to try to move, especially when stuck.
