Just as amazing as the ship, I'm in awe at the mazes of pipes, scaffolding, cranes, etc. Just think that teams of people had to design and lay all those structures out, and teams of more people had to cut and weld all those together.
Also the scheduling of it all; when building ships, there are things which must be done be for others such as welding in parts A,D,L before piece C is installed because if piece C is installed first, parts A,D,L can't be installed due to new physical access restrictions. It's a coordination master-work all by itself.
You would think so, but having worked on a ship built at SHI there is still a lot of installing part c, cutting it out, installing A, D, and L and then reinstalling C.
And to think they did this all without version control.
It's Object Oriented - they build the modules separately and plugged them into to the Framework (ship).
