Large integrated drilling and production facilities employ Dedicated Drilling Risers which have been part of the industries practice for decades.[1] In 1984 Conoco Hutton facility in the North Sea was the first facility to use the top-tension riser system. In the Gulf of Mexico there are several facilities using the dedicated drilling risers. The drilling risers' work as an extension from the wellbore to the drilling rig which is located on the floating production system. The typical riser configuration considered consists of the subsea wellhead connector assembly, tapered stress joint, drilling riser, tensioning joint, riser landing joint, hydro-pneumatic tensioning system and a surface blow-out preventer.[1]
