Abstract

The application of composite risers in offshore engineering for deep water applications has been facing a lot of challenges, such as in West Africa and Gulf of Mexico. Currently, the steel catenary risers are used for deepwater applications requiring large diameter pipes, while the flexible while top-tensioned risers are used for shallow water applications, but composite riser technology used mostly for deepwaters, as this is an exciting frontier in the offshore industry as it provides a potential solution for future riser design challenges. This research involves modelling composite riser using Orcaflex to investigate the Riser Installation behaviour. The behaviour of composite risers is compared against the behaviour of top-tensioned steel risers with the main research focus on the motion characterization and the behaviour as regards the fatigue of composite materials, considering that composite materials are light-weight, combustible but not corrosive. ANSYS APDL is used to model the composite materials and AS4/PEEK was first used considering the mechanical properties make it a good composite material for composite material.
