Explain the Non Destructive Inspection Steel/Cast Iron Substructures

Some of the structural defects in steel structures may not be visible during visual inspection. In that event more detailed non-destructive techniques (NDT) may be required under a Level III inspection. Following equipments may be used for NDT testing underwater.

-   Ultrasonic flaw detection for thickness measurements

-   Underwater magnetic particle testing for surface and sub-surface cracks

-   Radiography for internal defects
