The determination of collision bulkhead position by using consideration of ship grounding analysis

The ship collision case is an accident involving ship to ship damage or a ship damage only. An approach carried out to determine the effect of ship collision is by using numerical methods. Usually, an experiment method is used to verify the result of numerical method with the same model. The numerical method is based on the fundamental theories of explicit dynamics which the response of contact model is presented by time series. The ship and ground models are modeled in finite element software package. In order to obtain the same result between simulation and real condition, the ship is applied move forward to ground model. The internal energy is captured so that the stiffness of striking ship construction can be measured from this result. The ground model is assumed by using rigid body which means that the deflection and stress during simulation is neglected. From the result, it can be concluded that the effects of bulkhead position is in the 4.0 m from forepeak of ship. This position has considered that the ground model does not touch the bulkhead.
