The roll motion of a damaged ship immediately after a sudden flooding of one room, but before crossflooding is finshed, is investigated. The flow through the cross-flow duct and the air escape from the cross-flow room are modeled including some damping. The water volume in the flooded room is assumed either fixed or at equilibrium with the outer water. Sloshing, and seaway are excluded. The coupled air, water and roll motion are solved numerically and presented for a 133.5 m lomg RoRo ship (RoRo: roll-on/roll-off). The variations of peak values of the flooding-induced roll angle with tank size, cross-flow duct area, area of air escape pipe etc. are investigated. Regression formulae are presented for the maximum flooding-induced roll angle.
