Hydrostatics Analysis on the Uprighting Process of a Capsized Ship

Abstract:

The uprighting process of capsized vessel based on considering the buoyancy and stability of wreck was studied in this paper. The model of the righting force for the wreck salvage was established according to the mechanical characteristics of wreck. The analysis and calculation were demonstrated by the salvage module of GHS software in view of the problem of righting force programme, which need long computing time and large amount of data input. Take the simulation of righting a capsized yacht as an example, the three-dimensional model was established and the righting process was simulated via GHS software, the maximum righting force and the occurring phase, angle of vanishing stability and longitudinal distribution of torque values can be obtained from the analysis. And the results can play a crucial role in the uprighting process of a capsized ship. The uprighting process of inclining ship can be simulated by using the GHS software, which is suitable for making salvage scheme.
