In the latter part of the piping work, it becomes necessary to produce model pipes in order to effect adjustments to voriant factors, such as making measurement adjustments to suit the hull structure and various equipments and absorbing pluses and minuses in sizes caused in the process of drawing, production, and installment. Production of model pipes in such a way, however, has the big demerit of longer production time and cost compared to general production of pipes. At Tus Shipyard, our efforts for improvement started in the direction of reducing the labor needed to make pipes necessitate process of model, which resulted in the birth of "Model pipe's dimension analyse & reemergence unit" and related software. We then proceeded to develop, in order to do away with the production and transportation of model pipes, a "three-dimentional coordinate reading instrument (measuring instrument)" and the general system. The appearance in the marketplace of a measuring machine in the meantime facilitated the complection of our system. There is room more improvement, and we hope that you will let us know of any suggestious for improvement on our system after reading the following.
