that seems highly unlikely. The may do the parbuckling (=turning) of the ship in the fall, but then they still have to fit the other side sponsons before they can refloat her. I am sure it will be deep into the winter if not next year that they actually refloat her.
I would not be so sure as I have seen Titan Salvage working before in my diving days and they work 24/7.
They sure won't want her sitting there another winter if at all possible, i think once she has been 'rolled' they will put the other sponsons on a lot faster.
