Implementing iGPS for Large Volume Metrology in South Korean Shipbuilding Applications

Abstract

Korea took 42 per cent of the global shipbuilding market and grew its capacity thirteenfold between 2000 and 2006, using techniques – dockless and floating construction among them – that leave very little tolerance for dimensional surprises. This talk follows steel plate through substructure, block and erection, marking the key checking point at each step, and shows where iGPS fits: comparison to CAD within a few millimetres, coverage from a local cell to a whole factory, and six-degree-of-freedom monitoring for automation such as electrogas welding guidance. It closes on how iGPS works – standard GPS functionality with transmitters, sensors and a receiver hub in place of satellites – and what large-scale metrology is actually worth to a yard on that schedule.
