Steel Catenary Risers (SCR) have emerged as an attractive solution for subsea field development of deepwater offshore development. The notable advantage is the reliability and integrity of system over field life with relatively lower cost. However, the recent exploration success of High Pressure (up to 15-ksi) and High Temperature (up to 250º F) reservoirs (HPHT) has posed design challenges in terms of fabrication of thick-walled pipes, riser hang-off system selection, and longterm fatigue design. These challenges are further enhanced when the application is associated with floaters such as Semi-submersible, Floating Production Storage and Offloading (FPSO), and Tension Leg Platform (TLP).
ExxonMobil presents a reliable design philosophy for HPHT SCR design. The issues discussed herein center on fatigue design strategy of thick-walled section, realistic soil/pipe modeling and strain based design philosophy in survival and accidental conditions. Using some specific case studies the proposed design philosophies will be compared to general design philosophies adopted by the offshore industry.
