Results - Regular Wave Analysis

The regular wave analysis in this example corresponds to stage number 2. Results for this analysis are presented in the three figures below. Each plot represents an envelope of a particular parameter plotted against the curvilinear distance along the pipeline from the vessel connection point, ‘_TensionerVCP(1)’.

The effective tension envelope along the pipeline is shown in the first figure. At the tensioner end of the pipeline the maximum and minimum values are consistent with the deadband limits (+-10 % of 218 kN) . The tension extremes at all points along the pipeline are always positive, so the pipeline never goes into compression.

The bending moment envelope is presented in the second figure. The bending moment distribution varies significantly in the region between the vessel deck and the touchdown point. This is caused by the increased movement in the stinger region due to the motion of the individual stinger sections in response to the applied wave loading.  

The maximum Von Mises strain envelope is plotted in the third figure. A similar trend is exhibited to the bending moment envelope in that there are large variations evident in the region between the vessel deck and the touchdown point. Again these are caused by the significant motion of the stinger sections in response to the environmental loading.
