What to do in case of Parametric Rolling on ships? Do not panic in such a situation. Keep your calm If rolling and pitching occur simultaneously, avoid a head-on sea and change the route. Always maintain a correct GM. The ship should not be too tender or too stiff. The roll damping...
a method of equivalent roll damping is used to study the parametric rolling of the KCS container ship. This method converts the nonlinear roll damping calculated by CFD into linear roll damping. Then the parametric rolling of the KCS container ...
time domain 3D panel code based on impulse response function concept for the simulation of ship's 6 DoF motions.Validation of the developed code by comparison with tank tests.Correct prediction of the occurrence of parametric roll in all test cases, but less accurate prediction of roll amplitude...
pairs of U-shaped tanks and pneumatically controlled air valves, plus a control unit with pitch and roll sensors. The controller detects the starting phase of parametric rolling and tunes the tank water period and its damping characteristics by operating the valves according to the actual ship ...
are of the same order and the wave height is larger than a certain value; in oblique seas, ship roll motion is a forcedly-parametrically excited oscillation, primary resonance occur as the encounter frequency is near the roll natural frequency, which may lead to large rolling and capsizing ...
22. Furthermore, the influences of the elastic collision rate on the temperature increase of the atom cloud in the process of parametric excitation are also addressed. 23. A 4000TEU container ship has been taken as the research object, and the boundary of its parametric rolling in head sea ...
