Changing Stability of the Ship While Flooding Compartments in the Aspect of the Maritime Transport Safety
Author:
Abstract: The paper contains the computational stability issues after flooded ship’s compartment. Watercrafts, especially warships, due to the tasks they perform, are exposed to fires. The main extinguishing agent used on ships is usually seawater, which in large quantities poses a threat to the ship’s stability and subdivision. During the putting out of marine fires the ship’s compartments are flooded with this extinguishing agent. A free surface effect appears after a partial submersion of the compartment. It has influence on the deterioration of the stability of the entire ship and in particular cases may lead to its sinking. The threat to the ship’s stability is influenced by the flooding of high located compartments. Therefore, the main focus of the work was to determine the impact of the high-located ship compartment on the boat deck for the stability of the ship. The method of assumed mass and the algorithm of calculating the righting levers with respect to the free surface effect were used for the determination of stability parameters. The results of the calculations presented in the paper contain information about the amount of water in the range causing deterioration of the stability of the ship. The usefulness of the presented method is based on a quick assessment of stability while course of extinguishing and thus affects the safety of the ship. Usually, during the firefighting, the ship’s crew is focused on extinguishing a fire, not on assessing the stability of a ship. Based on the results of the graphical calculations, appropriate conclusions were done.
