Study On The Insubmersibility Of Bulk Carrier And Simulation System Of Flooding

This paper introduces and gives further study of the main principles of ship's insubmersibility. On the basis of the study , a simulation system combined with the advanced computer technology on bulk carrier is developed.With the increase of transportation on bulk cargoes, the accidents of bulk carriers are frequently occurred. Therefore, the safety of bulk carrier is widely concerned; The theory of insubmersibility is followed by the introductions of domestic and international regulations, solutions, rules and requirements on the floodability; Introduced are the conditions of hold in flooded condition, and provided are the calculation methodology of the stability and buoyancy when flooding. The concept of cargo permeability is concretely defined, and the calculation methods of the amount of flooding waters are executed; The application of the influence numbers simplify the calculation of the still water bending moment and shearing force in flooded conditions. A new method to calculate the maximum still water bending moment and shearing force is developed by means of the influence numbers; The simulation system provides a means of evaluation and forecast on ship's danger extent after ship is damaged. With the means of graphics input, the system simplified the input process in comparison with the digital input. The illustrative example of a 16700 ton dwt bulk carrier is also presented here in my thesis.
