After the accident of Exxon Valdez in 1989, sequential taker accidents have been occurred and caused sevier environmental poll ution to the sea. IMO set the regulation on the tanker structure that require double hull or equivalent structure to the newly built t ankers. Even after that, tanker accidents and sequential ocean pollutuon have been taking place.In this research, the technology to reduce the oil spill from tanker due to collision and grounding has been investigated, and the effectiveness and appropriateness of the technology has been examined. Detail FEM analysis and model experiment has been used to develop simplified analysis method for the analysis of damage extent in collision and tankers.Using the simplified analysis method series analysis has been carried out to examine the effectiveness of buffer bow structure.

1989年埃克森巴尔德斯号油轮事故后，相继发生了多起油轮事故，对海洋造成了严重的环境污染。国际海事组织（IMO）对油船结构作出了规定，要求新建油船采用双船体或等效结构。在本研究中，探讨了减少油轮碰撞和搁浅溢油的技术，并对该技术的有效性和适用性进行了检验。采用有限元分析和模型试验相结合的方法，建立了船舶碰撞损伤程度分析的简化分析方法，并利用该方法进行了系列分析，验证了缓冲艏结构的有效性。
