Now, not only visual inspection using high resolution and thermal imagery, but also Non-Destructive Testing (NDT) especially Ultrasonic Testing (UT) can now be performed by using drone. By having this solution, the process can be improved in terms of time and safety of the worker.
This solution can be used for onshore storage tank, especially the internal part of the tank. Besides testing, the drone is also equipped with blaster to eliminate soft rust and liquid penetrant.
