Cargo behaviors of the double hull tankers after the groundings and collisions which result in the damages of both the outer hull plating and the inner hull plating were investigated using the 1/50 scale models representing a midship section of a typical cargo tank of VLCC. Tests were carried out in still water, and a lubricating oil was used as the test fluid. Oil outflows were measured under the various conditions for the double bottom heights and the double side widths, the tank sizes, the extents and the positions of the rupture, the axial offsets of the ruptures, the initial thickness of the water layer in the double hull space, the drafts and the cargo levels. The dynamic characteristics of the water and cargo flow in the double hull space after an opening of the rupture were investigated.
