Again, I see having reinforced framing to cope with rough seas (IE, augmented scantling, more frames, more longitudinals, etc), but I don't see how a reinforced deck would help - The definition of reinforced deck here being "Reinforced to support weight", like the deck on a general cargo, or the tank top on a bulk carrier. Unless it's some sort of experiment, the ship had really heavy deck piping, or you mean the reinforcement for the helicopter area.
Liberty ships had midship accomodation, it makes sense to reinforce amidship, since you have a permanent local charge (IE, ship's heavier there)
Many ships have reinforced bow and forward section (The forward part plus 4% of the lenght of a Ice Class 1A, 2% of... etc, etc...) for ice navigation. All bows have to be strengthened for slamming.
I don't see how a ship could realistically takes so long to break up. Was there asbestos onboard? Where was she broken up?
