Results from the drift-off mode analysis are presented in the Comparing Von Mises Stress along Riser figure to the Drift-Off UFJ Angle figure (below). The Comparing Von Mises Stress along Riser figure shows a plot of the drift-off path of the vessel. The Drift-Off Path figure (below) and Drift-Off LFJ Angle figure show timetrace plots of the lower and upper flex joint angles, respectively. The Drift-Off LFJ Angle and Drift-Off UFJ Angle figures below show timetrace plots of the bending moments within the BOP and LMRP connectors, respectively.
