Vertical displacements displayed below for weight case only (selfweight including fluid). Right-side window is weight case with consideration of P-delta with large displacements with max vertical displacement of -8.69". Left-side window ignores P-delta effects and reports max vertical displacement of -41.5", which is what other legacy piping stress programs will report. With a long flexible pipeline like this, there is catenary behavior that needs to be accounted for in which axial load is being carried by the anchors to help support the pipeline . P-delta with large displacements accounts for this catenary behavior.
