CASE STUDY

Development of an Non-Destructive Evaluation System to Detect Pipework Crack Initiation

#Acoustic #FEA #HarmonicAnalysis #Oil&Gas

Our client from the oil and gas industry approached us to assist in the development of a non-destructive evaluation (NDE) system to detect pipework failures by capturing the acoustic wave transmitted through the pipe. More specifically, they wanted guidance on the requirements and the optimal spacing of acoustic sensors.

​

We developed an acoustic model of the pipework and simulated the propagation of an acoustic wave initiating from the cracking region along the pipe and reported the attenuated characteristics of the wave over pipework distance for pipework carrying different types of fluid, buried in different types of soil or being above the ground.

​​

​Based on our findings, our client selected appropriate acoustic sensors for different applications and spaced them in the recommended distance to maximise the system's detection accuracy and efficiency.
