Transverse Stability of a Cargo Ship at Parametric Rolling on Longitudinal Waves
Unfavourable environmental conditions associated with an insufficient stability margin adopted in the design process may determine ship capsizing. One of the most critical situations is generated when the ship moves on longitudinal waves, at parametric resonance condition. In this paper, the theoret...
