文档介绍：Block fabrication
Our workshop may produce blocks weighing about 200 tons. In the course of block fabrication, we may provide pre-installation of foundation, equipment, piping, cable bearer and iron outfitting according to block pre-installation list for hull, marine machinery, piping, electricity and outfitting present shown in production design.
DLS-4200 Proposed Method of Performing the Work
Section production plan
Stern area
Construct in the front with bottom plate as the reference plane and the assembly jig as supporting plates to have reversible deformation.
Lay bottom plates and install bilge board with rounded corner.
Install longitudinal frame and ribbed panel.
ponents like longitudinal bulkhead, transverse bulkhead and exterior panel etc. in platform and lift them up to the assembly jig in sequence.
Cover with platform plates, stern transom plates and exterior panels.
Measure block shape and levelness then hand over for acceptance.

Interior bottom block
Construct in reverse with bottom plate as the reference plane and the assembly jig as supporting plates to have reversible deformation.
ponents like ribbed panels, longitudinal girder and pipe casings etc. on platform and lift them up to the assembly jig in sequence bination.
Cover with bottom plates.
Check external dimension (length, width, height) of blocks and for any parts missed, then hand over for welding.
Apply welding to blocks turned over and supported to horizontality.
Measure block shape and levelness then hand over for acceptance.

Middle block
use deck, platform plates,
longitudinal bulkhead and transverse bulkhead as
the reference plane to construct in reverse the
laminar form and used assembly jig as supporting
Board.
-ponents like longitudinal girder and
big cross beams etc. on platform and lift them up
to the ass
