Acoustic emission testing in wires from the tensile armour of flexible risers under load
The need for an inspection technique that allows continuous monitoring of flexible risers and wire ropes has led to the development of non-destructive techniques. Among them, the acoustic emission (AE) method is a solution that might provide vital data on wire ruptures. The AE parameters can be used as input for pattern recognition techniques that could lead to automation. This work presents a study on the acquisition settings of an equipment suitable for the application, and compares the result of a resonant and a broadband AE transducer. The results have led to the creation of a reliability range for time-based parameters and show that, although both transducers can be used, the broadband is better for a frequency-based analysis while the resonant works better for an analysis based on hits.
