Investigations of transverse stability of semi-displacement ships

Abstract

In this paper results of experimental model investigations of transverse stability of semi-displacement ships are presented, aimed at determination of influence of their speed and hull form parameters on transverse stability. On the basis of these results algorithms were elaborated which take into account righting arm changes in function of ship speed, heel angle and geometrical hull parameters. The algorithms can be used for assessment of transverse stability of ships of the kind.
