Below is a list of links to OrcaFlex example topics. Within each topic are a number of examples which each comprise one or more simulation files, a description pdf file, workspace files and sometimes other supporting files. The files for each example are zipped for easy download. The simulation files can be opened and viewed with the demonstration version of OrcaFlex.
For this example, a line has been laid on the seabed along a specified route. It is to be pulled into a wellhead funnel by a winch. A gateway ahead of the funnel controls the pipe entry so it approaches at an angle that will not cause the pull head to jam.
This is an example of installing a riser over a subsea tower in 300m water depth. The riser is being paid out from the moonpool of an installation vessel and is supported from an auxiliary winch at the bow of the ship. Positioned approximately 14m along from the winch-to-riser connection point is a clamp, which has to be placed in the centre of the support tower.
This example shows how to model a typical J-tube pull-in operation. It includes pulling a line (a riser) out from a vessel over a chute whilst simultaneously pulling in the other end up a J-tube. It demonstrates the line contact model and introduces some tips for controlling the line position in the static solution.
