The report made for an interesting and challenging read to say the least, although I feel it should have been named "It's all the captains' fault", instead of "the report into the sinking and loss of life on the costa concordia".
I'm surprised that they lost all the bilge pumps so quickly (could they have been located on one side of the ship?), and that she sailed with an emergency generator that was clearly broken..
I think the issue with the emergency generator was more to do with an electrical distribution system which was underwater than any existing fault with the generator / system.
The standard survivability criteria is for passenger ships are all based on two breached watertight compartments, the damage to Concordia was way beyond this, while there will be lessons to be learnt from this which may improve things slightly in the event of a similar accident, I cannot see any way to keep a ship afloat after suffering damage such as that suffered by Costa Concordia.
What is also blatantly apparent from the report is that far from the Captain's actions in manoeuvring the ship closer to the port to aid the rescue efforts, she ended up in her final resting position by sheer luck.
