| Abstract: |
| In order to reduce the risk of the moving platform being in place in the area of repeated pile insertion and extraction in Chengdao Oilfield, the uneven seabed formed by repeated pile insertion and extraction is repaired through seabed topography and geomorphology investigation, planning of treatment scope and depth, selection of suitable machinery for construction, positioning construction, prognosis analysis, etc. Through case analysis, this seabed repair can increase the depth of pile shoes entering the mud,reduce the risk of sliding piles and puncture on the moving platform. |
