Typically it is ultrasound, or X-ray CT. It does become difficult to do with large pieces and/or thick sections, but I don’t know if this hull was too large. However, if the manufacturing process were qualified using smaller pieces that were testable with NDE/DE or a full size piece that was DE, that would generally be acceptable for the large component.
Do you know what would have been involved here? Some kind of imaging, I assume?
Thanks for the write up!
