WebDynamics of Ship–Motion The ship capsizing problem is one of the major challenges in naval architecture. The IMO criterion regarding capsize stability is still the righting lever curve of static stability calculated for calm water. For the prediction of large–amplitude motions the dynamic loads have to be included.

Dynamic stability assessment in early-stage ship design

WebThe dynamic stability criteria for a ship or an FPSO are set based on the stability requirement to withstand a sudden environmental change, e.g. a gust of wind. Vessels that are intact are required under the ABS certification to be able to withstand a 100-knot (51 m/s) wind in a storm-intact condition. ...

In contrast, a "tender" ship lags behind the motion of the waves and tends to roll at lesser amplitudes. A passenger ship will typically have a long rolling period for comfort, perhaps 12 seconds while a tanker or freighter might have a rolling period of 6 to 8 seconds.
