TM. No. As I understand it, by the time that all North Sea EC225 operations resume, every shaft will have been examined minutely not only by the techniques you mention but also by very close engineering inspection of the inside of shafts for any hint of "mud".
I believe that all shafts worldwide have already been scrutinised and the remainder of EC225s, flying elsewhere around the planet uninterrupted since last year's ditchings, have not been found to have any hint of stress corrosion or cracking.
According to EC, that's a collective total of over 20,000 hours of trouble free service from the other bevel gears in various countries.
