Outfit Modules

Units of machinery, pipework and other outfit systems required for a 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 receive them.
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.
