This example simulates an articulated S-Lay installation scenario. The model includes a lay vessel equipped with an articulated S-Lay stinger. The stinger is comprised of three stinger sections with three U-shaped roller boxes on each section. Hinges are placed at the start of each section in order to allow the sections to move independently of one another. The pipeline runs along a set of vessel supports before passing over the stinger sections and down onto the seabed. The pipeline is restrained on the vessel deck by a tensioner. The analysis sequence consists of initial static/quasi-static analyses in order to determine the overall static configuration of the system, followed by a dynamic analysis in which regular wave loading is applied. The overall system configuration is shown in the first figure below. A close up of the stinger region is shown in the second figure.
