The results of a series of numerical simulations of side damage due to collision was carried out based on an explicit FEM simulation system in order to demonstrate its potential power in the field of practical application. Assuming the simplified rigid bow of a 150000 tdw colliding ship, the energy absorption capacity of the various side double hull design options for a VLCC, such as increased number of side stringers, double side structure with top side tank in conjunction with hopper tanb and unidirectional girder stiffening system was studied. The contribution of each structural component was also investigated in detail. Based on the results of both thenumerical study and the 1/2-scale collision experiments, a new conceptualdesign of a VLCC side structure was developed. Further study on crushablebow struchture against collision and enhanced design of bottom structure against grounding is now in progress
