Results - Initial Static Analysis
The initial static analysis in this example corresponds to stage number 1. Results for this analysis are presented in the three figures below. The parameters of interest are plotted against the curvilinear distance along the pipeline from the vessel connection point ‘_TensionerVCP(1)’.
The effective tension distribution along the pipeline is shown in the first figure. It starts at the level imposed at the tensioner (3200 kN), but immediately begins to decrease in magnitude through the overbend and sagbend regions, until it becomes constant at the seabed.
The bending moment distribution is presented in the second figure. The most severe moments occur in the overbend region and less severe in the touchdown zone. The maximum moment experienced is in the region of 6500 kNm. The relative uniform moment profile over the stinger is indicative of the support elevation optimisation process applied earlier.
The maximum Von Mises strain distribution is plotted in the third figure. Similar to bending moment, the most severe strains occur in the overbend region, with a lesser peak occurring in the touchdown zone. The maximum strain experienced is just over 0.2%.
