The National Shipbuilding Research Program, 1990 Ship Production Symposium, Paper No. 3A-1: Advanced Industrial Measurement Systems for Productive Shipbuilding
Abstract
Modern shipbuilders have embraced the concept of modular construction and are realizing the gains in productivity associated with these methods. Further gains in productivity are achieved if these modules are built and erected neat, that is, without the traditional excess material normally trimmed at erection. Construction of neat hull blocks requires rigid control of accuracy throughout the production cycle. Interim products, from fabricated parts to erected hull blocks, must be measured to acceptable tolerances to prevent excessive rework. The object of this paper is to analyze viable types of advanced measurement techniques supporting the process requirements of neat modular construction. Documentation of costs and difficulties associated with each measurement technique selected are also analyzed. The first part of the paper is a general description and analysis of the systems. The second part describes actual demonstrations of three measurement systems and analyzes them in the shipbuilding environment. Demonstrations of digital theodolites, automated photogrammetry and an optical laser system are described and analyzed.
