ABSTRACT:
For fabricating a double-hulled tanker, or a major component of one including at least part of longitudinal midbody, a floating drydock is used which has two independently elevatable-depressible sections. The midbody part is made of individual modules, each of which is fabricated in an upended orientation. The upended modules are successively floated onto a tilting assembly on one drydock section, tilted over and serially added to a growing midbody on the other drydock section. The two drydock sections are pumped out and flooded as the process progresses for shifting the positioning of the growing midbody and modules. Other parts, including a bow and stern are added, to provide a complete vessel.
