Abstract
The application of weight losses to investigate corrosion effects on structural behaviour of an offshore structure under wave loads is presented in this study. Weight losses of sections obtained during previous experimental studies are implemented in the model. The jacket type structural model is analysed in its intact and deteriorated forms to demonstrate corrosion effects. The ABAQUS finite elements program is utilized and the fluid structure interaction (FSI) technique is adopted when modelling the interaction between solid and fluid domains. Mode shapes, first three natural frequencies, displacements of selected points, and maximum stresses, are comparatively presented.
