Abstract

— The Design of SCR (Steel Catenary Risers) has been requiring the processing of Finite Element Method Programs both time and frequency domain for extreme and fatigue conditions. These Programs require the knowledge of the drag (Cpj) and mass (C^) coefficients for each riser element. However, not as the vertically span supported conventional risers, the rigid (also the flexible) risers oscillate a greater amount about the static equilibrium configuration. For the former, the Coefficients are taken only as a function of the Reynolds number, but for the latter, the influence of the oscillations, regulated by the Keulegan-Carpenter number, has to be taken into consideration.
