The Simulation of the Interaction between SCR and Seabed

Abstract:

The simulation of the interaction between steel caternary risers (SCRs) and seabed was studied based on beam on elastic foundation theory and the node-spring system foundation mehod for comparison, with the SCR modeled by extensible flexibility cable curve beam. Not only the bottom support and the friction forces were taken into account, but also the damping force of seabed was included in the model of the interaction between SCR and seabed. The results show that compared with using the node-spring system foundation, the effect of the element length of the model on analytical result is insignificant and a longer element could be used for the model, when the beam on elastic foundation model is used. So, the analysis is not time-consuming and the memory requirement is not so large by using the beam on elastic foundation model.
