Sažetak
Statistics reveal that corrosion is the main cause of marine casualties in aged ships. Main adverse effect of corrosion is the reduction of the plate thickness leading to simultaneous increase of stresses and decrease of the structural capacity of ship structural components. It was recently found, however, that because of the complex interaction of various mechanical and chemical processes, mechanical properties, such as Young’s modulus of elasticity and yield strength of corroded steel reduces with time. Such long-term degradation of mechanical properties may further reduce structural strength that is not adequately accounted for in ship structural design rules and structural safety analysis procedures. The aim of the present paper is to investigate the consequence of degradation of mechanical properties on collapse strength of plates and stiffened panels. Standard procedures from Common Structural Rules for collapse strength assessment are employed. Corrosion degradation which is required for assessment of loss of mechanical properties is estimated based on real thickness measurements of oil tankers. Conclusions about importance of this phenomenon are drawn.
