Before applying environmental loads, a static equilibrium analysis is performed to verify the installed cable configuration and pretension level. Typical quantities that are evaluated at this stage are pretension (axial force) in the cable, bending moment and von Mises stress. These key quantities are illustrated in Figure 10-Figure 12.

If the obtained cable layout or pretension does not match the desired configuration, the following input parameters may be adjusted: pre-strain definition in the cable, prescribed translation and rotation of the back-end node. Several iterations may be required before the desired installation condition is achieved.

To verify that the cable has obtained the intended equilibrium configuration, vertical- and horizontal position could be plotted in AquaView. This is illustrated in Figure 13 and Figure 14.
