The process of magnetic particle inspection (MPI) crack testing is employed to assess the size and severity of cracks in ferrous metals that may not be easily visible. In situations where the crack's edges are identified, additional preventive measures like the stop drilling technique may be necessary.

MPI crack testing can be conducted in either wet or dry conditions, utilizing FN Diving's UV crack testing system for magnetic particle inspection (MPI) alongside competent personnel. Certain cracks may extend beyond the waterline, necessitating the deployment of MPI systems both above and below the waterline, which can be achieved with our specialized equipment.
