Thanks to recent hardware and software technology improvements, many kinds of technologies suitable for NDT. Especially, in oversea countries, robotics is used positively for NDT work. Reliablity, convenience and safety are drivers for plant owners to utilize these technologies.
The advantage of using robotics is that it can capture reliable inspection data, reduce outage time as well as costs for the project. Additionally, it can access the location where an engineer cannot safely access, i.e. confined spaces (inside tanks) and elevated pipes (pipes at a production facility).
