ON THE ULTIMATE STRENGTH OF BOW CONSTRUCTION

So far, the protection against collision of a nuclear powered ship has been evaluated by its own capacity for absorbing the impact energy. Recently, it has been reported that a resisting type barrier has been developed which absorbs the impact energy mainly by collapse of the striking bow. To design such a type of barrier, it is necessary to estimate the load acting on the side structure of the nuclear powered ship. This load is obtained by the following procedure: 1. Calculation of the ultimate strength of the bow construction of the striking ship to obtain a load-deformation curve. 2. Collision simulation analysis to obtain the bow deformation in collision. 3. Estimation of load corresponding to the bow deformation using the load deformation curve. To clarify the behaviour of the bow collapse and verify the calculation method, the authors have carried out theoretical studies and collapse experiments using 1/10 scale bow models of a tanker and a container ship.
