Example 11 simulates a Davit Lift scenario. It considers the lifting of a pipeline from the seabed to a vessel using multiple winch cables. The initial model consists of a pipeline lying flat on the seabed. The pipeline is connected to the vessel by three winch cables which are vertical initially. The analysis procedure is performed as a series of 6 static installation stages in which the lengths of the winch cables are adjusted in order to raise the pipeline to the vessel. The two figures below illustrate the Davit Lift process. The first figure shows the initial configuration while the second shows the final configuration.
