On the intact stability of a ship in head and following sea: an analysis of the dynamic roll angle due to sudden heeling moments

The verification of ship stability has been historically carried out on the GZ curve and on the dynamic lever curve. They are both evaluated in still water. Recently, new methods have been developed, accounting for dynamic instabilities in waves. The present research study aims to investigate on the dynamic stability of a ship in waves. This is carried out by means of numerical simulations of the transient roll response of the ship, caused by...
