Once the analysis has been successfully run, you can view various reports and results by clicking on the Results tab of the Analysis component and selecting the relevant buttons. Note that you must first select the stage of interest from the Stage drop-down list in order to view the results appropriate to that particular stage.

PipeLay also generates plots for the various parameters requested on the Summary Postprocessing tab. These plots illustrate the change in a particular parameter from one stage to the next. In this example, the summary postprocessing plots are reproduced in the first four figures below. Structure snapshots for each of the seven stages are also reproduced in the last figure.

The first figure presents tip separation as a function of stage number. The tip separation remains within the specified range throughout the installation process.

The second figure shows the departure angle as a function of stage number. The departure angle exhibits an opposite trend to the tip separation. As the departure angle reduces, the tip separation increases and vice versa.

The third figure plots the maximum bending strain in the sagbend region as a function of stage number. The bending strain remains relatively constant over the first four stages but then increases as the structure approaches the seabed. It then reduces again once the structure is wholly on the seabed.

The fourth figure shows the layback as a function of stage number.

The last figure presents structure snapshots at the various stages, all superposed onto the same graph. This summarises the overall abandonment scenario at a glance.
