engineering. now, it s finally set to float again. for the past ten months, engineers have been hard at work, attaching metal boxes to either side of the concordia. when the final checks are complete and the weather right, they will be able to drain the water from the boxes. in its place, they will pump compressed air, caution the ship to float. at first, they will raise it just two meters. it s a dangerous and tricky procedure. the ship is rotting and there s a real risk the bottom of it could give way. they will then tug the concordia 30 theaters in the east and lower some of the metal box on the starboard side of the ship. they will then attach more chain and cables to help reinforce the bottom. then, the full refloat begins, lifting the concordia up, deck by deck, clearing any debris along the way. once the ship is completely floated, they will tow it, slowly and carefully, 240 kilometers to the italian port
