Development of Ship-Building Assembly System for Ship’s Blocks Using 3D Measurements System

Abstract:

Most of Shipyards have adopted block construction method. In spite of efficiency, this method has been reported lots of problems. Overlap or gap between blocks, such problems are mainly caused by deformation of blocks. The ship’s block is built by thin plates which are processed by cutting and welding, etc. Deformation of block comes from process of plates by cutting and welding in the stage of block assembly. In the stage of block erection, overlapping or gap occurs between block’s parts which are caused by deformation of blocks. So, block accuracy management is the key point to production efficiency of shipyards. In this study suggests a 3D measurement based Virtual Assembly System (VAS) to solve those problems. This study specified principle function of VAS and implemented to check validity of principle function. Principle function of VAS is analysis of block’s deformation between design and measurement information and performs block erection process with measurement information in virtual assembly space. According to these principle functions, VAS has been implemented with ACIS for 3D geometric modelling kernel and HOOPS for 3D visualization library. Block deformation analysis and virtual block erection has been performed with two ship block to check validity of VAS.
