Abstract: Ship parametric roll is one of the main reasons for marine accidents and is introduced into the second-generation intact stability criteria by the International Maritime Organization (IMO) recently. In order to study the inner mechanism and predict the possibility of the ship parametric roll in head waves, a time-domain model based on the IRF (Impulse Response Function) concept and...
Abstract. The International Maritime Organization (IMO) is working on the finalization of the Second Generation Intact Stability Criteria (SGISC) intended to be included in Part A of the 2008 International Code on Intact Stability in the following years. The SGISC consider five modes of dynamic stability failure in waves: parametric roll, pure loss of stability, surf riding/broaching to, dead...
Surf-riding/broaching failure mode is one of the Second Generation Intact Stability Criteria (SGISC) dealt by IMO. The SGISC are structured with a multi-tiered approach: Level 1, Level 2 and Direct Stability Assessment (DSA). When a ship does not verify one level, the next once must be applied, or the ship design must be modified. If ship changes are not feasible, Operational Measures (OM) can...
