INTEGRATION OF MEASUREMENTS AND MANOEUVRING TECHNOLOGIES USED TO MODIFY CAISSON

The modification of the caisson in a dry dock is in many ways more difficult than conventional ship modifications. This is because of the accuracy required, 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 data on large structures. These data were formatted so they 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.
