tofd applications for hot hydrogen attack on carbon steel

I have heard of a TOFD application for measurement of hydrogen damage prior to the micro-cracking stages, I have a 3" carbon steel vessel that needs assessment work done, there are no available samples that have not been exposed for velocity ratio. Vessel is 18 years in service.
