海底管道水下不停输解堵方案设计

The Design Scheme of Unplugging in Subsea Pipeline

通球是了解海管运行状况的重要手段,但在实际操作中存在卡球、堵塞海管的风险,影响海管的正常运行。在常规手段无法解除卡球的情况下,须重新设计解堵方案。文章主要介绍了卡球解堵的两种方案设计思路及优化。

Pigging is an important method to grasp the operation of the subsea pipeline.But in practice there are risks of plugging,which affect the normal operation.In the case that the pig cannot be removed by conventional method,the unplugging solution must be redesigned.This paper mainly introduces the design ideas and optimization of two schemes for unplugging solution.
