Ladies and Gentlemen,
     Reference ACFM and
http://www.csmspace.com

State of the Art, Science, and Reliability of Underwater Welding and Inspection Technology Third International Workshop Houston, Texas • November 17 - 19, 2010 I attended. I heard ACFM as a way to do structure inspection underwater. Find cracks in tubular structures offshore. I had not heard of ACFM before going to Houston and a friend described it as

Alternating

Current

Field

Measurement

, a widely used technique with probes as with eddy current NDT but very low voltages and currents.
Below is a run on data bases of organizations that  am a member of. I believe it has bridge applications. I would be happy to answer question about the matter.
Sincerely
Len Andersen
