specific zone can be planned and built up into modules and installed as such
into a block fabrication. Pipework in particular lends itself to this form of
assembly and can, with careful planning from the CAD stage, be arranged in
groupings so that pipe bank modules can be arranged for a particular zone.
Modules can range from a small pipe bank supported by light framing of pipe
hangers, or a complete auxiliary machinery unit on its seating which has even
been test run prior to installation, to a large modular unit which together
with several similar units constitutes the bulk of a complete engine room.
Not all outfits can be incorporated into modules and a large number of piece
parts have to be provided for fitting in any given zone at a particular time
within the assembly shops. To maintain production engineering standards a
concept of ‘palletisation’ has been developed whereby the piece parts for that
zone are generated at the CAD/CAM stage, bought in and/or fabricated etc. and
made available at the work station when the particular assembly is ready to
An ‘open top’ arrangement for block or smaller ships being outfitted under
cover can facilitate installation of the items and modules.
Superstructure blocks are fabricated separately and pre-outfitted with
accommodation before erection as a complete unit. Modular cabin units are a
common feature of modern shipbuilding, Figure below shows a typical self
supporting cabin/toilet module complete with pipework, ventilation, electrical
fittings, wiring, and all built-in furniture.
