This paper introduces the outline of the digital manufacturing in shipbuilding and the application results of it, with the aim of the modernization of ship manufacturing, following the application of shipbuilding CIM. The pipe unit assembly in a shipyard was taken up as an example, because the assembly work has depended on individual experience of skilled workers, and not been generalized and digitized. As a result of the work analysis in the site, it was found that the assembly worker often moves to observe the drawing plan to image the final feature of the assembly unit even veteran workers. Hence, the assembly simulation program was developed and a PC was introduced in the site, so as to assemble the pipe unit in accordance with the computer simulation on the display. The method was effectively tested and verified in the site. In addition, the wearable computer system was applied in a pipe factory to check the delivered pipes, to sort them, and to allot them to the pallets. These applications were confirmed as one of the effective digital manufacturing system.
