Analysis And Design Of Safety And Reliability To Prevent Ship Collision Of KT Official Ship

The ship confronts with the risk of collision.Ship collision is a kind of marine damage accidents of ships contacting with other objects,which would leads to structure damage,leaking,environmental pollution and even casualties.Hence,the crashworthiness is significant from the safety,economic,and environment friendly aspect.In recent years,East sea and South Sea of China see the fierce dispute and tense conflict.US's “Back to Asia” containment doctrine causes more out-standing sea sovereign issue.The Chinese official enforcement ship confronts with the foreign ships more furiously and Collision run tactics is common in those confronts.With the above mentioned factors,the fighting capacity and survive capacity,present novel concepts of structural design and the Impact resistance improvement are very critical in official sovereign enforce action.The major research work and conclusions of this paper are summarized as follows:1 This paper has a review of the studies of ship collision,testing methods and relevant literature.2 According to <Domestic sailing vessel construction rules> of CCS in conventional design and calculation,Determine the basis of the selected model side structural components parameters.3 Using the method of finite element analysis,modeling,computation and simulation by the aid of the finite element analysis software MSC.PATRAN and MSC.NASTRAN.This paper makes a series of related solution and simulation by setting different collision conditions,including position of collision,collision angle,collision speed,collision time and the weight of striking ship,and has a qualitatively analysis and discuss on the various parameters caused by the collision results.4 This paper also tend to simulate and analyze the different influences on the results of the collision under extraordinary conditions,after taking side plate improvement,taking side longitudinal improvement,and taking joint improvement.The conclusion of this simulation provides valuable reference for future related research.
