Stability Analysis of Subsea Wellhead Oil Control Device
Shiyou jixie, 2016 To ensure the subsea wellhead rescue oil control device do not experience instability during switching operation,a reasonable in-mud depth of the oil control device need to be determined.In view of this,the mechanical model of the subsea wellhead oil ...

Safety Analysis on Drilling Riser-wellhead System in Drilling Ship Drift-off Condition
Shiyou jixie, 2017 The warning circle of the conventional drilling platform is determined by static analysis, which is a static analysis method that does not take into account the trajectory of the platform under the load of wind, wave and current, and cannot determine the

Fine Evaluation on Wave Induced Fatigue of Deepwater Subsea Wellhead in Full Drilling Process
Shiyou jixieThe traditional evaluation on wave induced fatigue of subsea wellhead does not consider the changes in the composition of subsea wellhead structure at different drilling stages,resulting in limited accuracy in wave induced fatigue evaluation of subsea ...
