Damage survivability of a new Ro-ro ferry

This paper presents experimental investigations involving the dynamic behaviour and survivability of a damaged ro-ro passenger ferry. It concerns a modern design, which has an extensive lower hold for ro-ro cargo purposes. Two main damage scenarios have been considered: lower hold intact and damaged. Besides damage survivability in beam waves, the research focused on the ship dynamics as a result of transient flooding following a breach of the intact huil. The following parameters have been varied: KG, creation rate of damage opening, cross duet area, internal configuration and cargo deck permeability. Some conditions have been simulated numerically.
