6. Assembly:
Assemble the North wall to support each South corner while it is assembled. Alternatively, brace it to the warm vessel floor.
Bolt the 4 long-wall panels together on the warm vessel floor.
Bolt the 3 short-wall panels together on the warm vessel floor.
Bolt the two sub-assemblies together supported by the North wall.

7. Transport from the NE to the SW corner:
There is space to rotate the SW corner to correct orientation.
