Over the past 30 years, computer-aided ship design and construction has progressed from mainframe computers to PCs, from independent programs to fully integrated programs, and from large shipyards to all sizes of shipyards. More to the point, key advances during the past several years have made 3-D product modeling a tool that can significantly improve small yard efficiency, quality, and profit. However, 3-D product modeling can do these things only if implemented in a planned and well thought-out manner, tailored to the specific yard. 3-D product modeling, when combined with other innovations such as NC production equipment and the workstation approach to production…
