Note:

Abstract: The existing intact stability criteria (2008 IS-Code) of IMO do not generally provide sufficient safety against dynamic stability failures such as parametric rolling for modern ships. Therefore, new stability criteria have been developed by IMO / SLF. These so-called Second Generation of Intact Stability Criteria shall ensure sufficient dynamic stability. We have applied the criteria to a reference ship whose stability was precisely assessed during the design by model tests and seakeeping simulations. Curves for the required GM of the ship have been calculated for the criteria. The results showed large scatter in the accuracy of the particular criteria. Compared to the direct assessment, some criteria could assess reasonable stability values and some could not. The fact that some criteria were not able to identify unsafe stability values clearly shows why a criterion based on direct assessment is urgently required before the first two levels can enter into force.
