I think most of us remember the Costa Concordia and the tragic end that came to the ship and 32 of its passengers.
Well after two years of resting on the rocks on its starboard side it has been righted through a process called Parbuckling.
Here's a link to a great webpage that describes the process and has a 90 second video of photos of the process. http://gcaptain.com/the-costa-concordia-parbuckling-in-pictures/
It's worth seeing. I think the most amazing thing to me (not counting that they were able to get it off the rocks) was looking at the damage to the starboard side where the ship was lying on the rocks.
