In this study, the characteristics of roll damping for two types of the hull (PCC: Pure Car Carrier
and LNGC: Liquefied Natural Gas Carrier) were investigated experimentally. Their draught is
shallower and the height of the centre of gravity is lower than those of the ships which exist when
Ikeda's method was developed. Their roll damping was measured to investigate their characteristics,
and the measured results were compared with the estimated results by Ikeda’s method. Moreover,
the measured results were compared with the estimated results by the modified Ikeda’s method
which has some modifications related to the effects of the draught and height of the centre of
gravity, and the applicability of the modified method was verified.
