The general plan and methodology of the project are presented in the book. The project is focused on the analysis of the structural strength of the hull and the ultimate capacity of structural elements and the hull girder of the single hull VLCC, taking into account the influence of the uniform and atmospheric corrosion. Based on the model that describes the phenomenon of the corrosion, a model (2) (see chapter 4) has been introduced. This model is based on the approach which was taken from ref. [13]; this one used to develop a methodology to predict gaping thickness of structural elements due to corrosion. The results obtained using the prediction methods were verified against the experimental results. ukryj opis
