Integration and Implementation of an Advanced Measurement System into The Assembly Process in Support of 'NEAT' Hull Block Construction and Erection.

摘要

In the NSRP study 'Advanced Measurement Techniques for U.S. Shipbuilding', Report 0300, issued in March of 1990, state of the-art advanced measurement techniques were identified and tested in-yard on various processes supporting neat hull block construction and erection. Those techniques which were found to be effective tools for measuring within the shipyard environment were evaluated and their usefulness extrapolated to assembly, assembly and erection. Although the per measurement the remaining processes of fabrication, subcost of each of the advanced measurement techniques were evaluated, the overall potential cost savings attributable to each system in a particular stage of construction could not be estimated due to the limited time frame and scope of the field tests. Therefore, this study proposes to extensively demonstrate practical strategies for integration and implementation of an advanced laser based Optical Coordinate Measuring System (ACMAN) into selected processes supporting 'neat' hull block construction and erection. In addition, the implementation of the integration strategies will be evaluated and analyzed for actual labor costs and cost savings achieved per measured unit. Finally, overall cost savings potential of an advanced measurement system will be estimated.
