A fast tool evaluating cross-flooding effects: Application to a Megayacht unit

To forecast the ship behavior after the damage is a challenging commitment. In case the flooding moves across adjacent spaces with complex geometry, the adoption of high-level numerical tools such as CFD simulation is quite time-consuming. In this work, a fast numerical tool able to reproduce the ship progressive flooding in the time domain involving rooms with complex geometries is proposed. The work highlights the relationship between the damage opening, its position, the connection opening, and the time to fill the first flooded room. The versatile applicability and its rapid calculation time may represent important characteristics, especially in the early design stages when a large campaign of application is needed.
