In deepwater exploration, Steel Catenary Risers (SCRs) are extensively employed in riser systems. Static and dynamic bending stresses are the largest at the touchdown point (TDP) where the SCR first touches the seabed, and thus fatigue damage is most significant at this location. Unfortunately, chal...
