Structural Reliability Analysis of X-mas Tree Tubing Hanger
As subsea production has been revved up, the demand of subsea equipments has also been increased.Among the equipments, subsea tree plays a major role in safety.The tubing hanger is one of the most important components in subsea tree.In this study structural reliability analysis on dual bore tubing hanger of subsea tree is performed.The target reliability which is introduced in ISO regulation is used for judging whether tubing hanger is safe or not.The considered loads are working pressure, working temperature and suspended tubing weight.Thermal-stress analysis on tubing hanger is performed and kriging model is created based on the results of FEM analysis.According to von Mises criterion, limit state equation can be estimated.Reliability analysis is performed by using level 2 method and the result is verified by that of Monte Carlo Simulation.For finding most probable failure point, enhanced HL-RF method is adopted.Because the reliability of model doesnt reach target reliability, an improvement measure should be considered.Thus, it is suggested to change the material of tubing hanger main body to AISI 4140.
