Have used them for many years. Ship owners would have the crew or outside company do a grid pattern on the hull from inside, or outside with divers, and give the results to the USCG. Depending on hull thickness, Coast Guard would waive the annual drydock requirement and save the company many dollars, if hull thickness was over 75% of original.
Also used before drydock to get idea of amount of hull and bulkhead steel that needed replacement.
