age isn't the issue...metal structure and repair cost is pretty much the entire structure seems to be destroyed. Undoing that damage and then rebuilding what was destroyed will be effectively (if not greater than) the cost of just buying a new one. Even if you could repair it, you don't want to. A large amount of the metal has been heated to very high and unknown temperatures. Typically, the concern is three things [0]: dimensional changes (i.e., you warped your entire ship), increased corrosion (hot metal rust faster), and permanent reduction in strength (like, >50% permanent reduction in strength). Now add in that the fire has almost certainly burned or boiled the paint off the external surfaces that are contacting sea water. That paint is the the skin of the ship, any of that underlying steel would need to be expected, cleaned, and likely repaired. Age isn't the issue, the damage is. It would be like trying to renovate a burned out house. At some point it's not a renovation its a teardown. EDIT: adding the obvious 'this is my opinion based on observations and I have no first hand data on this ship' qualifciation [0] https://www.edtengineers.com/blog-post/fire-effects-steel https://www.edtengineers.com/blog-post/fire-effects-steel
