Considerations are given to structural integrity, fatigue performance, and metal-to-metal sealing capability. Various load combi- nations (bending, tension/compression, pressure) were applied to generate the wellhead...

Design of SCRs by distributing weight along the riser enhances the fatigue performance of SCRs thereby extending the feasibility of SCRs for deep water harsh environment whilst fulfilling both strength and fatigue requirements. The weight distribution...

... lifetime is 6.3 years in the studs of the SID. Therefore, long-term wave fatigue is not critical. In a 1-yr storm, the minimum wave fatigue lifetime along the riser is 36 days, and 30 days from the 1-yr current at a different connection. This fatigue performance is acceptable given the 1-day duration...
