Most Production Life-cycle Management (PLM) systems are built on top of CAD/CAE, Product Data Management (PDM) and Enterprise Resource Planning (ERP). It is well known that the cost of deriving information technology solutions for shipbuilding is very high; there is an ever increasing need to reduce manufacturing costs. Furthermore enterprises need to take the risk of integration with legacy systems into consideration. This paper describes an implementation approach for a manufacturing management system that integrates CAD, ERP and other vertically-related systems for Hull production management. Through information technology, the system combines the upstream CAD models to ERP database. At the contract stage, the system considers the production code necessary to start the assessment materials, loading feed and acceptance. Then material information and three-dimensional ship models are combined to form plate cutting plans and cutting drawings. Using the loading schedule, the system controls the whole hull production management from upstream to downstream. Finally, full documentation collected by a special classification scheme can be delivered and used as the ship's data management.
