Rigid steel risers have been recently implemented on the Shell Auger TLP. Compared with conventional flexible risers, rigid steel risers offer a more economic alternative. Furthermore, steel pipe allows larger diameter risers to be considered in deep water. In this paper, a further development of the concept is discussed.
