H05 - Steel Pipe Installation with Plastic Deformation

This example considers the installation of a steel pipe which experiences plastic deformation as it passes over the vessel stinger and is landed onto the seabed. J-Lay installation is typically used in deep water but this example uses an S-Lay configuration as it leads to high levels of bending strain as the pipe passes over the stinger. So the example is somewhat artificial as it is specifically crafted in order to illustrate Flexcom’s ability to model plastic deformation.

The example is divided into the following sections:

•Introduction gives an overview of the analysis.

•Model Summary describes the structure from a modelling viewpoint in Flexcom. Important modelling techniques for this type of analysis are noted, as well as relevant Flexcom features and capabilities.

•Analyses briefly describes the various analyses performed, discussing the environmental and loading conditions.

•Results presents pertinent results from the various analyses performed.
