The outputs from a Staged Operations fatigue analysis are as follows:

▪Fatigue Damage. A plot of the fatigue damage as a function of distance from the Common Reference Point.

▪Standby Time. The maximum time the suspended pipe can be held stationary in any given stage.

▪Vessel Welds and TDP. For each stage, the fatigue damage rate and the maximum fatigue damage occurring in a single pull at each of the vessel weld locations and the touchdown point.

▪Maximum Nodal Fatigue Damage Rate. The maximum fatigue damage rate for all nodes along the pipeline during a particular stage.

▪Plot of Variation of Damage Rate along Pipe. Nine plots are generated in total for any given stage - one plot for each of eight points on the pipeline circumference, and a ninth plot showing the maximum of all eight values at each node.

Plot of Maximum Rate of Change in Restoring Force Statistics. For every stage, six graphs are presented on a single plot; one each for the mean and standard deviation of axial force, y-bending moment and z-bending moment. There are additional optional outputs if you set Generate Histogram Output to Yes; they are as follows:

▪Fatigue_hist.csv. Contains the stress histogram data for 8 circumferential points for each node. This can be viewed by clicking the Open Histogram Output button on the Results tab.

▪Accumulated Tracked Weld Stress Histogram Data. This is the governing accumulated weld stress histogram data for all tracked welds. This data can be viewed in the fatigue.out file.

▪Plots of Accumulated Tracked Weld Stress Histograms. A governing stress histogram plot is produced for all tracked welds.
