Analysis of hull performance on fast patrol boat with an extended study of survivability under damaged conditions

The prevalence of maritime accidents that occur due to ship leakage causes a significant risk to the safety of passengers and crew. Therefore, it is important to estimate stability during critical conditions, including characterizing the hull performance in sailing conditions. This research analyzes the effect of compartments and bulkheads on the ship's stability when a leak occurs. The research method was carried out using the numerical approach to obtain resistance, stability, and large-angle stability results. The study also uses floodable length simulations to predict ship leakage and the distance between compartments. The variations were composed, including the location of the compartments and the distance between the partitions. Based on the obtained results, it can be seen that the addition of the compartment will affect the intensity of the ship to sink completely. Furthermore, the effect of leakage in each compartment will contribute to the stability state of the ship.
