摘要
海底管线因碰撞而发生损坏是其面临的主要安全威胁之一,其中锚泊作业引起管线破坏是其中的1个重要方面。依据海底管道风险评估方法,建立锚泊作业时脱锚和锚链断裂情况下抛锚时撞击海底管线概率的数学模型,分别对锚和锚链撞击海底管线的风险影响程度进行研究。利用模拟仿真的方法对建立的数学模型进行了例证研究。
One of main security threats that the offshore pipeline faces is that it may be broken because of collision,among which the most important aspect comes from anchoring work of ships.Based on the risk assessment of offshore pipeline,the risk degrees of anchor and chains to collide with offshore pipeline are studied according to the mathematical model of the probability of collision with offshore pipeline under the circumstance of anchor rupturing and anchor dragging respectively.At last,the mathematical model is further explored by simulating an example illustration.
