Abstract

Collision is considered as a time-depended nonlinear dynamic phenomenon. The majorityof researchers have focused on deriving the resultant damage of the ship collisions via analytical, experimental, and finite element methods. In this paper, first, the force-penetration curve of a head collision different ship (Abuzar.Abazari, 2011). Nonlinear finite element method (FEM) is a powerful tool for analysing ship collision problem and has been seen more and more applications in the recent years. Expectedly, more and more FEM simulation application will be seen in the coming years. Rapid advances in computer technology and software capacity have made FEM simulation a viable choice. Ship collision simulations still face some difficulties in terms of providing reliable results. The accuracy of numerical modelling results significantly depends on the proper definition of the phenomenon and careful control of the some critical parameters such as rupture criteria, non-linearity, element type, friction coefficient, and mesh fineness. Present paper attempts to investigate the parameters on the ship collisions and provides greatest human made disaster ever to occur sea environmental due to this accident there is oil spillage of around 40,000 tons in the fresh sea surface, still that part is suffering from the environmental pollution (Hong, 2009). Resulting this Grounding effect resulted the oil pollution act according to U.S government in 1990 each and every oil tanker operated in U.S
