The system modelled in this example consists of a SCR hanging from an installation vessel via a winch cable. A second winch cable joins the top of the SCR to a second vessel (TLP). The transfer process involves increasing the length of the cable joining the SCR to the installation vessel while simultaneously shortening the cable running from the SCR to the TLP. The entire transfer procedure is performed as a series of seven static installation stages. The two figures below illustrate the the transfer process. The first figure shows the initial configuration while the second shows the final configuration.
