Effect of Riser-Seabed Interaction on the Dynamic Behavior of Risers
In recent years, the production of oil and gas has been developed in deep water depths which exceed 500m. Deep water developments are being followed strongly in different parts of the world (Caspian Sea, Gulf of Mexico, etc.). The movement of floater causes severe stress at the touchdown point (TDP) in steel catenary risers (SCR). The main objective of this study was to simulate the exact behavior of the riser in the vicinity of the touchdown zone (TDZ) by implementing linear SCR-seabed interaction model. Hence, present study attempted to investigate the riser-seabed interaction during lateral cyclic pipe movements and also the influence of seabed evolution around the TDZ based on the vertical cyclic movements. Moreover, The significance of the soil types in the response of riser pipeline at TDP was analyzed based on the vertical and lateral interaction. The fully non-linear time domain finite element model was utilized to simulate the riser behavior.
