| Abstract | To guarantee the safety of a ship by preventing accidents, various regulations, including those related to the ship design, must be followed. Despite these efforts, accidents may occur. Personnel injury or oil spill are highly probable during an accident. Therefore, this study proposes a method for analyzing the intermediate state of flooding to predict the motion of the ship, and the amount of flooded water and spilled oil during an accident. Quasi-static analysis has been primarily used for intermediate flooding analysis. However, limitations exist with respect to dynamic effects and ocean environmental loads. To overcome these limitations, a dynamic flooding analysis method is proposed in this study. Cummins’ equation is used to analyze the six-degrees-of-freedom motion of a ship, while the dynamic orifice equation is used to calculate the flow rate through damaged holes and openings in the ship. Additionally, a method is proposed to consider the oil spill over a period. This method is verified in comparison with other studies, and its feasibility is confirmed using three case studies of a Navy oiler. |
