To develop methods based on ultrasonic guided waves and tomography to inspect a tank floor (diameter up to 100m) without the need to empty and clean the tank.
The ultrasonic technique for non-destructive inspection of the tank floor based on the application of Lamb waves transmission tomography has been developed. The pilot investigation carried out on the real tank under in situ conditions has proved that this novel technique is suitable for condition monitoring of a storage tank floor using measurements around outer edge of the floor and it does not require emptying and cleaning of the tank. The investigation of propagation of Lamb waves in the tank floor has demonstrated close relation between properties of propagating waves and presence of the non-homogeneities or corrosion. Prediction of the transmission losses enables to estimate that measurements can be performed on up to medium sized tanks.
