An IT solution is the cutting edge technology in shipbuilding industry today. Many shipbuilders have implemented the virtual ship design concepts using 3D CAD system. It will be remarkable if the prospect ship quotation can be estimated using this virtually designed ship. Accurate quotation is very crucial milestone of the shipyards to succeed commercially. This paper describes a methodology that can be adopted to retrieve all necessary realistic data needed to estimate the realistic quotation of manufacturing a ship. The research will also open the doors for future research activities such as complete-Automation for quotation, realistic manufacturing scheduler and inventory management of shipbuilding based on the virtual ship.
