Once the analysis has been successfully run, various reports and results may be viewed by going to the Results tab of the Analysis component and selecting the relevant buttons (Note: The stage of interest must be selected in the Stage drop-down list in order to get the results appropriate to that particular stage).
The SCR initiation is performed in the second stage, and the results of this stage are of most interest. Results for this analysis are presented in the figures below below.
The first figure presents structure snapshots taken at regular intervals throughout the analysis, all superposed onto the same graph. This neatly summarises the overall SCR initiation process at a glance.
The second figure plots the effective tension in the winch cable at the installation vessel for the duration of the initiation process. The tension increases steadily as the SCR is deployed from the FPU, and reaches a maximum of approximately 850 kN, just as seabed contact is initiated. From there on it remains relatively constant.
The effective tension distribution along the pipeline is shown in the third figure. The maximum value of over 1075 kN occurs at the FPU, where the greatest portion of SCR is suspended. The tension is slightly lower at the installation vessel, approximately 860 kN, as the pipeline contains some winch cable at this end. Naturally the tension is constant in the portion of pipeline lying flat on the seabed.
The bending moment distribution along the pipeline is presented in the fourth figure. Peaks occur in the two touchdown regions, with magnitudes of over 300 kNm. Naturally there is no moment in the portion of pipeline lying flat on the seabed.
