HPHT BOP ANALYSIS

Background​

FEA Simulation of a high pressure and high temperature (HPHT) BOP and Wireline valves assessing sealing function of rams as well as robustness of mechanical design.

The model considered nonlinear effects such as elastomeric seals, plasticity, large displacements and contact. Local damage was evaluated as per ASME section VIII Div 2 design by Analysis rules.

Thread plasticity and failure load was assessed including stress at the root and contact pressure of the threads to properly assess fatigue and the risk of thread galling. ​
