The acoustic emission technique (AET) is widely used for detecting and monitoring damages and progress on damages in various structures, and it has acquired a reputation as one of the most dependable and well-established non-destructive testing techniques. Acoustic emission is a very efficient and effective technique for detecting fracture behaviour and fatigue in metals, fibreglass, wood, composites, ceramics, concrete, and polymers, among other materials. It can also be used to detect defects and pressure leaks in vessels, tanks, and pipes, as well as to track the progress of welding corrosion. A standard AET technique is also established in this study. The findings of this feasibility study can be utilised to support future offshore field tests of AET on operational structures. The findings revealed that the case company has a considerable need for systematic condition-based maintenance methods to do the right things at the right time and in a cost-effective manner.
