Abstract

A series of full-scale flooding tests was performed with a decommissioned fast attack craft. Various flooding scenarios were investigated and the floating position and progress of the floodwater were carefully measured. Also air compression inside a flooded tank was studied. The results were used to validate a state-of-the-art numerical flooding simulation tool. A comprehensive analysis of the experimental and numerical results is presented. A good correlation is found, especially when the applied permeabilities and discharge coefficients are properly selected. Finally, the stability of the flooded ship was studied by comparing the results of an inclining experiment and calculations with the lost buoyancy method.
