Addressing the New IMO Guidelines for Second Generation Intact Stability

The common perception of intact stability has remained largely unchanged over the last few decades, where a vessel’s stability is evaluated using classical and static means: limits on righting arms, residual areas, and determining maximal VCG (or minimal GM) composite curves. These methods are familiar to most naval architects and are taught at a fundamental level in most naval architecture engineering programs.But repeated incidents of dynamic failure in recent decades brings question to the adequacy of classical static stability criteria to provide a complete understanding of…
