ON THE INFLUENCE OF RESTORING MOMENT CHANGES IN WAVES ON STABILITY ESTIMATIONS

In this paper a procedure is described for evaluation of the total sum components of the ship restoring moment in eaves, developed in the frames of the hydrodynamic theory of ship motion and some results of its numerical realisation are given. The validity of the approach is verified for the case of following waves by systematic captive model tests. The influence of the inclination angle, the speed of advance and the frequency of excitations on every restoring moment component is analysed. The stability estimation changes due to the restoring moment variations and the conditions, at which these changes influence considerably the stability assessment process, are examined.
