摘要
对埕岛海区平台附近海底管道出现悬空的安全隐患进行了详细的调查,对产生悬空原因进行了分析,对悬空管道的悬空控制进行了对策研究,形成了采用"水下支撑桩"方法进行管线悬空治理的施工工艺。实施后取得了显著效果,为保证海底管线安全、保护海洋环境提供了有利借鉴。
According to the detail free span survey of submarine pipeline approaching to platform in Cheng Dao offshore area Shengli Oilfield and based on the research of span rectification methods and mechanism which causes pipeline span, this paper develops 'underwater steel pile support' technology to protect free span pipeline. This method has a good effect to ensure the span pipeline safety after carried out.
