How do you salvage a 600 foot ship laying on it's side?

It will be interesting to see how they go about salvaging the ship. How will they right a ship that is carrying over 4000 automobiles that have most likely ended up shifted to the low side in a massive pile of wreckage? I wonder how they secure that many cars in the cargo holds to keep them from moving about in rough seas, much less in a capsize situation. Even a 600 foot ship is going to roll a bit in rough weather, even if it is nosed into the oncoming waves.

  That particular ship is a RORO vessel, Roll On/Roll Off.  Typically the vehicles are secured to the deck much the same way they are secured to a flatbed tow vehicle, just strap 'em down.  But being rolled like that?  Oh boy!  What a mess that is going to be!
   I can't imagine there would be a vehicle on that thing worth a crap when they are unloaded.  Oil, coolant, broken batteries/acid leaking, let along the physical damage!  I hope the shipper has some damn good insurance.
