Interesting image. Green circle is the 003 (called 002 on this forum) and it shows a very large chunk already assembled. With possibly even larger piece, hidden by the movable roof cover. We're talking about 100+ meters of ship hull being assembled, almost to the main deck level.
It appears that they are assembling the hull ON that place. If its 100+ meters, i have doubts that this piece of the hull can be transported anywhere, but i could be wrong.
