There are 132.000 fuel stations in the EU that must regularly inspect their ageing underground storage tanks to abide by strict regulations and avoid leaks and failures that can have catastrophic consequences. Currently, inspections are performed in regular intervals using portable systems operated by specialised inspectors, a method that is costly and unreliable as it is prone to human error. This project will develop an autonomous end-to-end solution for structural health monitoring of underground storage tanks that has the potential to revolutionise the sector. MoniTank combines acoustic emission and technologies, risk-based inspection techniques, and advanced signal processing and data acquisition systems in a single bespoke system enabling an Internet-of-Things approach. It will be able to provide continuous monitoring and will use intelligent algorithms to predict potential structural failures able to identify with 99% accuracy structural integrity threats before they evolve to problems or lead to ruptures and failures.
