Research: Guided wave EMATS for inspection of external corrosion
Sponsoring company: Sonomatic
Undergraduate Masters in Physics, University of Warwick, June 2012. Final year project in the ultrasound group was based on the medical use of ultrasound for detection of osteoporosis in heel bones and provided my first introduction to the ultrasound and non-destructive testing community.
My research involves the testing of petrochemical pipelines for defects trying to improve the information that can be gained from the screening of pipes using a circumferential guided wave scanner.
Guided wave screening scanners using SH wave electromagnetic acoustic transducers (EMATs) in systems that can be automated for application above ground and subsea are being developed at Sonomatic that can provide good qualitative information on the presence of a defect in a pipe in terms of axial extent and circumferential positioning. However, it is difficult to give anything but a degree of severity of the defect. My work is aimed at quantifying the remaining wall thickness of the pipeline by using more precise measures of EMAT probe behaviour, operation points and anticipated wave speeds in order to quantify wall loss. This is being carried out both on artificial defects and real corrosion patches.
