Abstract:
The floodability of a container vessel is investigated to determine the maximum volume of compartments that can be flooded without causing the container vessel to capsize. In this project, Maxsurf modeler was used for the hull design and Maxsurf stability enterprise for the floodable length analysis of a container vessel at several displacements, number of transverse water tight bulkheads and its positions from AP to FP and a constant permeability value for the compartments. Floodable length is the preliminary check on damage survival. It is used at the initial concept design phase because it is faster than a full damage stability analysis, it checks if the vessel has sufficient buoyancy to sustain damage and stop from sinking straight to the bottom. Maxsurf Enterprise marine design software is used to determine the results. The output of the analysis shows a floodable length curve and the curves that represent different displacements, if a displacement line is below the allowable floodable length of a compartment then the vessel will not survive damages but if the line is above the allowable floodable length then the vessel will survive damages. The result also shows that it is easier for the vessel to survive heavily loaded conditions with more compartments.
