The Plot > Plot Settlement Shell Settlement ICON option in the local graphics environment produces XY type plots detailing the shell settlement evaluation according to API-653 Appendix B.

Click the down arrow on the Plot Settlement icon to access additional display options for the settlement plot.

  • Use Plot Settlement > Plot Measured Elevations to show or hide the measured elevations on the plot.

  • Use Plot Settlement > Plot Optimum Cosine Curve to show or hide the optimum cosine curve on the plot.

  • Use Plot Settlement > Plot Out-of-Plan Deflection to show or hide the out-of-plane deflection on the plot.

  • Use Plot Settlement > Display Plot Legend to show or hide the legend on the plot.

  • Use Plot Settlement > Spline All Data for Display to spline the plot data. Splining the data smooths the plot points into curves and makes for better presentations.

The settlement plot uses two Y-axes. The far left Y-axis is for the out-of-plane deflection curve. The Y-axis closest to the curves is for the measured and optimum cosine curves. These axes and their associated curves are shown in different colors for better visualization.

The settlement plot positions the curves on an X-axis showing the relative angular position around the tank circumference from the point of maximum settlement. The settlement plot also includes a secondary X-axis which shows the location of the actual measurement points.
