Secondly, the shift in offshore exploration from shallow to deep waters has necessitated advancements on more lightweight composite structures to minimise platform loads, ease fluid transport, and service, such as conduit pipes with composite production risers (CPR). The properties of composites are harnessed to improve riser weight and strength performance as Composite risers. In this research, the local tailored design of deep water composite risers was subjected to burst, collapse, tension and combined loads. Three design methodologies are considered- conventional, local, and tailored designs for different configurations. The structure is made up of configurations having 17 layers, 18 layers, 19 layers, 20 layers and 21 layers. The numerical technique for the CPR model with 3m section considered five loadings. The model was developed utilising ANSYS ACP to conduct the numerical stress analysis with parametric studies. From the design, it is recommended to consider liners like PA12 and include environmental loads from global design. This study presents the CPR behaviour.
