The International Association of Classification Societies (IACS) Harmonised Common Structural Rules (CSR-H) have been released and will take effect on July 1, 2015. The local loads under extreme motion conditions, defined in the CSR-H, were investigated for an oil tanker by using computational fluid dynamics (CFD) software, STAR-CCM+, and included bow flare slamming pressure and bottom slamming pressure at the bottom of the bow or stern bottom. The extreme motion defined in the CSR-H was investigated using the potential code HydroSTAR. To benchmark the numerical results, resistance and seakeeping model tests were performed on the oil tanker. The two test results were simulated using the two software packages, respectively, and the numerical results were in good agreement with the test results. Finally, this study demonstrated that the slamming pressures defined by the CSR-H are safe and conservative with regard to the structural design.
