Ultimate strength performance of bulk carriers with various corrosion additions

In this study, various types of industry corrosion addition practices are investigated with regard to the ultimate strength performance of bulk carriers. Five types of corrosion additions, namely previously applied structural design rule, CSR (common structural rule), harmonised CSR, time-dependent corrosion wastage model, and new suggestion of corrosion addition by Union of Greece Shipowners, are considered. In the previous study, investigation on the ultimate strength performance of oil tankers associated with corrosion additions has been performed. In the similar way, four types of bulk carrier structures, namely 37 K (Handysize), 57 K (Supramax), 82 K (Kamsarmax), and 181 K (Capesize), are studied. The ultimate strength performance of hull girders and stiffened panels is examined through various corrosion additions used in industrial practices. The obtained results would be useful in understanding the corrosion addition effects in terms of ultimate strength of bulk carriers.
