Abstract EN
ABAQUS is used to create a detailed finite element model for a 10-layer unbonded flexible riser to simulate the riser’s mechanical behavior under three load conditions: tension force and internal and external pressure.
It presents a technique to create detailed finite element model and to analyze flexible risers.
In FEM model, all layers are modeled separately with contact interfaces; interaction between steel trips in certain layers has been considered as well.
FEM model considering contact interaction, geometric nonlinearity, and friction has been employed to accurately simulate the structural behavior of riser.
The model includes the main features of the riser geometry with very little simplifying assumptions.
The model was solved using a fully explicit time-integration scheme implemented in a parallel environment on an eight-processor cluster and 24 G memory computer.
There is a very good agreement obtained from numerical and analytical comparisons, which validates the use of numerical model here.
The results from the numerical simulation show that the numerical model takes into account various details of the riser.
It has been shown that the detailed finite element model can be used to predict riser’s mechanics behavior under various load cases and bound conditions.
