I'd wager they will use what is known as a 'Float-on/float-off' ship for transport... it's rather common actually-

It's a ship with a very low deck line that partially submerges itself, with the center of the deck underwater deep enough so the other vessel can 'float on' over the deck. They they pump the water back out, raising the deck above water and the boat on top it just rests flat.

They do this for some oil rigs as well.
