An improved Moving-Particle Semi-Implicit (MPS) method was used to numerically simulate the transient flooding process of a freely floating two-dimensional damaged ship section. First, a near-wall particle search technique was developed to support the computations using the improved MPS method. This technique was verified via sloshing simulations. Then, numerical flooding simulations were performed for various models of this ship section, where a hole was located at different positions to represent broadside and bottom damage. In addition, flooding simulations were carried out with baffles located inside the damaged ship section. The damaged hole and the internal baffles affected flooding and motion characteristics of the damaged ship section. Greater distance of the hole from the calm water surface and the ship section's center caused larger motions. Vertical baffles had a greater influence on flooding than that from the horizontal baffles.
