Example 8 simulates an as-laid span scenario. It considers a pipeline lying on a seabed with an arbitrary topography. The pipeline is flooded with seawater. Both ends of the pipeline are pinned to the seabed, with one end adjusted to satisfy various tension criteria at the seabed connection point over the course of three installation stages. Multiple static analyses are performed in order to examine the stresses in the as-laid configuration lying on the arbitrary seabed for each tension criteria.The figure below illustrates the initial static configuration of the pipeline on the seabed.
