Prefabrication

Rather than plan outfit installation on a total ship system basis, it is today common practice to plan this work for zone installation, the zone corresponding to a main compartment area which may e broken down into blocks or smaller assemblies. Pre-outfitting of each assembly or block may be or the order of 85-90 percent. Both steelwork and outfit are highly planned for each assembly and block unit, and fabrication and outfit installation is undertaken at a work station where the facilities and material are supplied.
