The traditional inspection processes are based on manual operations that are subject to technical limitations and human factors. Additionally, these processes are likely to require the access of inspectors to areas that are uncomfortable or dangerous, like elevated structures and confined spaces. This creates problems of cost and falling risks when the pipe is located at height.
A single petrochemical facility includes more than 50.000 inspection points since every pipe must be inspected regularly. But insulated pipes make this process more difficult as the insulation covers the possible defects. These pipes cannot be inspected using ultrasonic sensors due to the insulation and require more complex inspection systems, such as X-ray and Pulsed Eddy Current (PEC). Then, usually, the entire insulation is removed directly to perform the inspection.
SIMAR pretends to overcome this issue, facing the following major challenges:
