Riser Inspection

Our techniques are specifically designed to minimise intrusive inspections wherever possible. Unlike other companies our primary inspection method is Guided Wave Testing (GWT).
Guided Wave Testing using the Wavemaker Pipe Screening System uses ultrasonic guided waves, sent along the length of pipe, to non-destructively test pipes for defects and other irregularities. This technique detects changes in the cross sections of the pipe.
NDT Global Services boast a range of inspection capabilities and methods.
