Structural Reliability Analysis of Subsea Tree Tubing Hanger
Journal of the Society of Naval Architects of Korea, 2014 As subsea production has been revㅑved up, the demand of subsea equipment has also been increased. Among the equipment, 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.
