Catenary and Hybrid Risers for Deepwater Locations Worldwide Event: Catenary and Hybrid Risers for Deepwater Locations Worldwide Date: June 1996 Author: S. Hatton, H. Howells Floating production systems offer the most practical method for developing medium and deep water oil and gas reserves. A wide range of tethered and catenary moored production vessel designs have evolved including TLP, SPAR, tanker, deep draught floater, semi submersible, and their derivatives. As water depth increases the cost of the riser system, used to transport production fluids from the seabed to these production vessels, becomes a higher proportion of the total field development cost. Consequently, it is increasingly important that proper attention is paid to the design and selection of the riser system early in the design loop. The riser systems currently implemented on deeper water production systems are mostly adaptations of shallow water concepts. However, a number of new riser concepts have been developed in recent years that offer technical and commercial advantages over the systems typically used in shallow water. The following paper discusses two of these systems and the factors that affect selection of one system over the other. Riser system evaluation and selection is a complex process. It is not sufficient to simply compare hardware costs and a full evaluation of the impact of the riser system on the overall development cost, schedule and risk is required.
