Petrochemical/gas pipeline is the key infrastructure supporting energy industrial sectors. They are important assets to the operators, and structural integrity of pipelines needs to be assessed in a timely manner to mitigate safety risks and potential financial loss. Corrosion is the most common defect type of any pipelines, but currently remotely quantifying corrosion severity is challenging because most of the pipeline sections are difficult to access physically posing difficulties to examine the pipeline part. In this project, we will develop long-distance guided wave inspection method with particular improvement in the detection sensitivity and defect imaging capabilities towards micrometre scales; such as level of capability would enable a revolutionary change compared to he current inspection methods. The students will be work on both simulations and experiments, including developing imaging methods and collaborate with our industrial partners in HK.
