I guess the latest is that the engines were not actually damaged, although I don't know if they could have flown someone there to examine them or not. I think the problem is that if they did try to re-start the engines and there was a problem, the automatic fire supression system had already fired, so they couldn't use it again and if there was another fire, it would have been out of control?

I guess for newer ships, built after 2010, redundency systems are required, so I supposed the answer is, don't sail on a ship built before 2010!
