The hydrodynamic and dynamic motion analysis of a damaged ship

Abstract

The hydrodynamic analysis and motion response of a damaged ship requires a novel generalisation of the methodsnormally applied to intact ships or other floating structures. Damaged ship statistics are used to provide likely damage scenarios. Water ingress, arising from the hull damage will require special attention regarding the influence of the presence of internal free surfaces and the modelling of the air stiffness associated with the within cargo hold air located between the internal movable free surface and the deck. The additional ideas required are developed and applied to a damaged optimised bulk carrier, the Derbyshire. This hull form is selected because of the well-publicised available associated structural details
