Abstract
WPS/PQR is the essential documents for shipbuilding welding. WPS is the document containing the information related to welding procedure and PQR is the record of approval for welding procedure. Both documents should be approved by the ship owners and the classification societies. It is very important to manage these documents because the welding procedure using these documents could not be carried out before they are approved. Database is an useful tool to manage these documents. It can manage a number of documents and show the processing status of WPS/PQR documents. In this study, all documents related to WPS/PQR documents were investigated and analyzed in the viewpoint of DB. An appropriate DB system was designed for WPS/PQR and the related documents on the basis of CBD methodology. The DB system could make WPS/PQR documents easily and shortly. The grasp of the processing status of WPS/ PQR could help the good management of fabrication schedule in shipbuilding.
