Geez, I can't even imagine how hard that had to be to design when you figure that every single pipe, duct, conduit, hall, wall, floor, ceiling ... EVERYthing had to go in one side of the "addition" and come out in the exact same spot (ie one side of the cut to the other).
A ship that has reached it's economical end of life can be made profitable (and thus given a new Economical end of Life) by giving it a stretch and retrofit. Thus the ship can be used again until it again reaches EEoL and is replaced or until it reaches its mechanical EoL
It`s also possible the ship had been bought by a new company, as it had reached EEoL at the original company and was replaced. Buying a used ship and stretching it would be cheaper than getting a completely new one build for a smaller company.
There`s several shipyards across the world specialized in exactly this sort of thing. Most ships are even designed with a midlife upgrade in mind afaik! There is a good chance that the center section had already been designed with the ship.
