船舶锚泊作业对海底管线的拖拽损害

Dragging damage of anchoring operation upon the subsea pipelines

针对渤海海域近年来频繁发生的由于抛锚导致海底管线损害故障,对锚和锚链拖拽力进行分析,选取实际船舶计算抛锚作业对海底管线的拖拽力,分析锚泊作业对海底管线的拖拽损害,可为船舶抛锚作业对海底管线损害的风险评估提供依据.

In recent years, more and more anchoring damage to subsea pipelines happened in Bohai Sea. The paper analyzes the dragging force of the anchor and anchor chain, and calculates the dragging force of anchoring operation upon the subsea pipelines using the actual data from a ship. The dragging damage of ancho- ring operation upon the subsea pipelines is estimated, which can provide some basis to the risk assessment of the subsea pipelines due to the anchoring.
