Results - Initial Static Analysis

The initial static analysis in this example corresponds to stage number 1. Representative results for this analysis are presented in the three figures below. The parameters of interest are plotted against the 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 on the seabed, increases in magnitude through the sagbend region, and further increases linearly through the tower. The magnitude at the tensioner is approximately 2305 kN.

The bending moment distribution is presented in the second figure. The most severe moments occur in the touchdown zone. Relatively small peaks are evident at the lower supports on the tower. The maximum moment experienced is in the region of 1420 kNm.

The maximum Von Mises stress distribution is plotted in the third figure. Similar to bending moment, the most severe stresses occur in the touchdown zone. The maximum stress experienced is around 220 MPa.
