Quantifying ship’s dynamic stability through numerical investigation of weight distribution
conference contribution
posted on 2023-05-23, 13:43 authored by Hossein EnshaeiHossein Enshaei, Kianejad, SSThe Roll resonance can occur both in the parametric roll and dead ship condition, where the roll angle increases and endangers safety of the ship. The effects of loading conditions and weight distributions on the aforementioned phenomena are unknown. This study uses CFD method to investigate the effects of loading conditions, different vertical centre of gravity (VCG) and roll moment of inertia on dynamic stability. A model of a container ship is excited by a roll exciting moment at different frequencies and Froude numbers. The effects of VCG and loading conditions on the dynamic stability are compared against hydrostatic characteristics for the similar conditions. It was found, their effects in the static condition are more significant than the dynamic condition.
