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. This is constant for the portion along the vessel deck, decreases in magnitude through the overbend and sagbend regions, and is constant again along the seabed. The magnitude at the tensioner is approximately 5000 kN, which is within the range of allowable criteria values.
The bending moment distribution is presented in the second figure. The most severe moments occur in the overbend region, with a lesser peak occurring in the touchdown zone. The maximum moment experienced is in the region of 3000 kNm.
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 under 0.295 %.
