I’m no expert on marine salvage, but I do work in the Submarine/Navy Ship building industry…
I did some work in a Dutch Engineering Research Lab a couple of years back, they had a section of the wire saw they had developed to cut up the Kursk submarine, to salvage it off the sea bed.
It had ‘teeth’ about the size of a 2.5L paintcan threaded onto a 2″ diameter steel cable, like giant beads.
The ‘saw’ would be threaded under the object you want to cut up and two ‘nodding donkeys’ mounted on a ship above would rock up and down to saw through the ship/submarine.
There is a good chance they could move that cruise ship in one piece, as compared with modern bulk carriers and tankers it isn’t that big, however if it isn’t repairable there would be no point and it would be easier (and cheaper) to cut it up in-situ.
The big issue right now is to try and stabilise it to stop it sustaining any further damage, and do their best to stop anything nasty leaking into the sea..
aside from diesel fuel you’ve got thousands of litres of hydraulic fluids, lubricants, engine oil, sewage, waste food and a few tonnes of refrigerant gas to try and contain..
There must be salvage companies falling over each other to get involved with this job…
