Warship damage flooding is an interactive process between progressive flooding and counter-flooding measures under battle-damaged conditions. Traditional damage stability theory cannot simulate the influence of counter-flooding measures on the damaged warship flooding process, and there is no method for predicting this process in the full-time domain.

By analyzing a coupling relationship between the damage flooding process and counter-flooding measures, a flooding process time domain model is established and a numerical solving algorithm obtained. Case studies are analyzed on the basis of the model and algorithm, and an interactive visual simulation system is developed.

The simulation systemcan comprehensively assess the flooding process and various counter-flooding measures, providing an important supplement for warship damage stability theory.

This study can help designers to understand the effectiveness of counter-flooding design schemes on the flooding process and guide the design of counter-flooding systems. In addition, it can be used for shipboard flooding decision-making, giving it high military application value.
