WebAn innovative aspect of such criteria, is the comprehensive view of ship safety as an integration of design and operational aspects. These criteria tackle five stability failure modes that may occur during navigation: parametric rolling (PR), pure loss of stability (PL), dead ship condition (DS), excessive acceleration (EA), and surf-riding (SR). WebThese criteria ensure a level of stability performance after damage. Like the intact stability criteria, the inherent level of safety in these criteria and the link to the dynamic performance of the vessel in waves is little known.
