The base of the vertical riser is fixed in all degrees of freedom. The upper ends of the jumper hoses are fixed in all translational degrees of freedom.
In this analysis the boundary conditions remain unchanged and are carried through automatically from the initial static analysis. A piecewise-linear cross current is also applied to the hybrid riser system. The direction of the current is constant with depth and is aligned with the positive sense of the global Z-axis. Two current analyses are performed, one with the Blevins wake model applied and the other without. The affects of including the wake action in this model are detailed in Results.
The clearance between the jumper hoses is computed using Clear, the Flexcom postprocessor for clearance/interference calculations. Separate runs are performed for the cases including and excluding wake interference effects.
