Example 1 simulates a normal S-Lay installation scenario in deep water. The S-Lay model includes a lay vessel equipped with an S-Lay stinger, which is fitted with V-shaped rollerboxes. A pipeline runs along a set of vessel supports before passing over the stinger and down onto the seabed. The pipeline is restrained on the vessel deck by a tensioner. The example includes a static analysis and two dynamic analyses, one with a regular wave loading and the other with a random sea loading. A top tension of 5000 kN is specified as the installation criteria for the static configuration. The figure below illustrates the static configuration.
