Study on Integrated Model of SCR-Spar System Affected by Soil Suction
Based on the theory of a slender rod with bending stiffness, Steel Catenary Riser (SCR) is modeled as a small extensible cable. Considering the factors of Spar motion and soil interaction, coupled dynamic analysis for SCR-Spar in time domain is developed using the program developed from a cable dynamic analysis computer code CABLE3D. The paper focuses on the effect of soil suction on dynamic response, tension and bending moment obtained from modified program at key zone of SCR. The results indicate that riser flexural rigidity and soil suction play important roles on affecting the dynamic curvature at the Touch Down Zone (TDZ).
