Remotely operated crawler system used to conduct ultrasonic thickness survey on above ground Ferro-magnetic structures without the need of costly scaffolding or rope access. It provides effective inspection solutions for difficult-to-access tank walls and roofs and other remote locations. The (semi) motorised tank wall scanner can climb carbon steel tank wall with magnetic wheels.

Technique capability:

• Only ferrous Structures can be inspected.
• Produces B-Scan images of thickness.
• Works at different heights.
