Risk Assessment of Ocean Pollution Caused by Collision and Grounding of Tankers

1989年埃克森·瓦尔迪兹号油轮事故后，连续发生事故，对海域造成了严重的环境污染。国际海事组织（IMO）对新建油船的结构进行了规定，要求采用双壳或同等结构。即使在那之后，油轮事故和连续的海洋污染仍在发生。本研究对减少油轮碰撞和搁浅溢油的技术进行了研究，并检验了该技术的有效性和适宜性。通过详细的有限元分析和模型试验，建立了碰撞和油轮损伤程度分析的简化分析方法。采用简化分析方法对缓冲弓形结构的有效性进行了序列分析。

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.
