Abstract

Due to recent challenges in oil exploration, there has been an increase in oil exploration from shallow waters to deep waters. This requires more length of the risers and thus an increase in the weight of the risers on the offshore structure. Risers are conduits which are used to transport fluid from the oil well to the offshore platform of transport vessel. The application of composites in riser design is to harness the properties of composites. This includes the reduction in the weight of the structure, and to improve the material behaviour. Submarine hoses are also a type of risers that are connected to buoys and other offshore structures but have short service periods. The design for some load cases on the composite riser is presented.
