| 摘 要： | 当船只抛锚点附近有海底管线时,为了防止置于海底的锚链对管线可能造成的危害.需要采取一定的措施将位于海底管线上方的锚链提起.结合实际工程设计采用浮筒提供足够的举升力提起锚链,并以悬链线方程为依据,推导浮筒位置和高度对锚链形状和被举升段长度的关系,从而确定出合理的浮筒举升力大小和浮筒安装位置.

| Abstract: | In a recent platform installation design,the connecting wire rope is required to pass a crossing pipeline.In order not to damage the pipeline,the wire rope has to be lifted up from the seabed to prevent the wire rope from touching the pipeline.A hollow cylinder is fixed onto the wire rope,whose buoyant force will lift the wire rope up to a certain height above the seabed.In order to determine the position to fix the cylinder,an iterative procedure is developed,with which the applied force and the length fro... |
