The figures below present envelope plots of effective tension, bending and von Mises stress respectively. At the tensioner end of the pipeline the maximum and minimum values are fairly consistent. This is consistent with expectations as the tensioner applies a constant force equal to the static tension. The tension extremes at all points along the pipeline are always positive, so the pipeline never goes into compression. The bending moment distribution varies significantly in the overbend (stinger) region due to wave induced motions, as the individual stinger sections are free to rotate about their hinged connections. Considerable variations occur in the sagbend region also, and the touchdown zone in particular. The final figure plots a sample time history of the contact reaction at the lowermost support (in the stinger tip region).
