Will be interesting to find out what happened. If someone accidently hit

Does this ship steerable props (such as the Azi-Pod)? If so, then there's
no way the helmsman could make the ship roll no matter how hard he turned.


Would tend to disagree here. You put a ship into a hard turn, the mass of
the ship is going to make it lean towards the outside line of the
turn.....no matter what the propulsion.
Now, I also doubt that the angle they achieved was really as high as
speculated (that high up and it will seem much worse that it is) but it
doesn't take much of a roll which is not expected to start throwing people
and things around, but back to your point.... although Z-drive and azipod
are different, I know a Z-drive will lay itself over in a hard turn but I've
never been on an azipod unit when making one and I would have to think that
on these ships, the stabilizer (if working) would tend to minimize the roll
angle ..... a lot of speculation on my part and why I'm going to be
interested to hear the final reports.


Other possible contributor would be "stabilizers".

Bingo

As for "top heavy".... she does look it, but the reality is that she
probably isn't.


I dunno, the ABS has recently decided that use of active stabilizers
counts for stability. Maybe they have some sort of absolute guarantee that
the system never goes down? In any event, the standards for ship's
metacenter has been changed. Maybe when one of them falls on it's side and
the crew has to right it like a Laser,

the standards will change back again?

Counts in what way? I can't imagine that it in anyway could count for
initial or damage stability, but may allow a slightly reduced one under
certain operating conditions. As for "top heavy", be it a cruise ship or a
car carrier most of that space is relatively empty (i.e., not a lot of solid
weight) so that looks aside I'm betting they still have a pretty good GM
..... course, as with the car carrier Tricolor, it doesn't take much water to
play hell with that GM.
