基于远场涡流检测技术的海管立管内检测方案

Inline inspection on riser of submarine pipeline based on remote field eddy current detection technique

  • 摘要: 海管一旦发生泄漏事故,将对海洋环境产生一定程度的污染,因此对海管定期进行内检测,监测其腐蚀程度的工作越来越受到重视。采用远场涡流检测器对海管立管进行内检测,并设计出一套详细的采用远场涡流检测器检测海管立管的内检测方案。现场实际应用结果表明:该方案在海上施工可行度高,远场涡流检测器不但能够准确检测和定位立管的腐蚀程度及位置,而且由于远场涡流检测器不与海管内壁接触、尺寸较海管内径小,避免了卡球风险,解决了远场涡流带缆进行海管立管内检测的难题,对海上立管内检测工作有一定的指导意义。

     

    Abstract: Leakages of submarine pipelines may induce pollution to marine environment. Accordingly, more attentions have been paid for periodical inspections of inline conditions of submarine pipelines to determine their corrosion. A new scheme for inline inspections of riser in submarine pipeline is developed by using remote field eddy current detector. Field applications show that the new scheme can be deployed in offshore operation sites. The remote field eddy current detectors not only can detect and position corrosion and specific positions within riser accurately, but also can effectively eliminate possibility of sticking in submarine pipelines with minor IDs, since no contact between remote field eddy current detector and inline walls of the submarine pipelines is required. In this way, challenges related to inline inspection of riser by using remote field eddy current and relevant cables can be solved effectively. The new scheme may provide valuable guidance for inline inspection of riser in submarine pipelines.
