Abstract
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.
Claims8
A subassembly for a double-walled vessel hull construction, comprising:
- a plurality of subcomponents each of which is T-shaped in transverse cross-sectional shape;
- each said T-shaped subcomponent comprising a faceplate having two opposite longitudinal edges, a longitudinal rib plate having two opposite longitudinal edges, and a two-plate longitudinal T-weld by which one said edge of each said longitudinal rib plate is welded to a respective said faceplate at a site which is disposed intermediate the respective said two opposite longitudinal edges of the respective said faceplate;
- said T-shaped subcomponents being arranged adjacent one another girthwise of said vessel hull construction, with relative rotation through 180 degrees about respective longitudinal axes thereof, so that faceplates of successive ones of said subcomponents are arranged to provide respective portions of inner and outer hulls of said vessel hull construction;
- said subcomponents being united into said subassembly by respective longitudinal three-plate, three-edge welds each formed between respective said longitudinal edges of two adjacent faceplates which are arranged to provide respective portions of a respective same one of said inner and outer hulls and a respective other said edge of a respective said longitudinal rib plate.
