Model Summary

The model is a top tensioned riser concept, based on a free standing hybrid riser arrangement as shown in the Hybrid Riser System Configuration figure. A close up of the upper section is shown in the figure below. The system consists of a single vertical rigid steel riser, anchored to the seabed and tensioned by means of a buoyancy tank with a connection to an FPSO through two flexible jumpers. One of the jumpers takes oil from the wellhead, while the other injects gas into the production stream. The top of the buoyancy tank is positioned approximately 50m below the water surface. The wake interference effects are modelled using Blevins, (2005) formulation.
