SUMMARY

Structural health monitoring(SHM) is essential for modern industrial development, in particular in the aspect of maintaining the integrity of huge mechanical structures such as storage tanks or shells of transportation vessels. In such context, the inspection of marine transportation vessels presents an even more challenging problem due to its extremely corrosive working environment and the uncertainty of their working schedule, which prevents it from regular, long-term inspection. How to tackle this problem to achieve fast, light, preliminary health inspections have become a paramount challenge in the field of SHM.

The overall objective of this project is to be able to develop a robust signal processing method for information extraction and evaluation to achieve inner mechanical structure detection and visual reproduction. Such a method could be further developed with better precision and robustness to inspect mechanical defects which are considered minor reflectors compared to the detection object in question here.
