A subcomponent for a subassembly of a module of a longitudinal midbody for a double-walled vessel hull is fabricated by welding an edge of a rib to an intermediate location on a face of a hull plate. A plurality of such subcomponents are alternately arranged and positioned in a fixture so as to dispose a free longitudinal edge of a rib plate in juxtaposition with adjoining longitudinal edges of two outer hull plates, or with adjoining longitudinal edges of two inner hull plates. At each of these sites, the three adjoining edges are welded together, thereby fabricating subcomponents into subassemblies. By preference, the hull plates are flat.
