Because of the large undivided deck spaces, RoRo vessels are often sensitive to rapid capsizing due to sudden ingress of water. Following a high-energy damage, a rapidly increasing heeling moment is induced by the ingress of water, which generates a roll motion of the damaged vessel. If, additionally, the car deck is flooded and/or the cargo is shifted, the heeling moment may exceed the residual restoring moment, which results in capsizing.
