Integration of Measurements and Maneuvering Technologies Used to Modify Caisson

Abstract

The modification of the caisson drydock is in many ways more difficult than conventional ship modifications. This is because of the accuracy required, the location of the measurements, and the size of the structure. The development of computer-based multi-headed electronic theodolite systems made it possible to extract accurate data on large structures. This data was formatted so it could be input directly into a computer-aided design system. The multi-headed electronic theodolite system was used to transfer new design information directly to the structure. The caisson structure was modified and moved safely into position with the aid of a water castor system for final assembly. Final dimension checks verified the accuracy of the system.
