The study presents an experimental investigation on the corrosion degradation level assessment using nondestructive wave-based methods. The degradation level of ship structural elements has been assessed in two different ways. The first one is based on the spectral decomposition and zero-crossing incorporated reconstruction of the dispersion curve approach of the antisymmetric Lamb wave mode and the best matching of the theoretical...

Ships and offshore structures operate in a severe corrosion degradation environment and face difficulty in providing long- lasting corrosion protection. The Classification Societies recommend regular thickness measurements leading to structural component replacements, to ensure structural integrity during service life. The measurements are usually performed using ultrasonic thickness gauges and such an approach requires multiple...

This study provides an overview of the key findings from a research project funded by the Polish National Science Center that examined the progressive collapse of ageing structures subjected to corrosion degradation and locked cracks through numerical and experimental means. The study aimed to determine how age degradation affects the strength of metal structural elements, such as steel plates and stiffened panels, as part of ships...
