Compliant risers are assemblages of pipes with very small overall bending rigidity used to convey oil from the ocean floor or a subsurface buoy to a surface platform. The objective of this work is to present a general nonlinear mathematical model describing the global behavior of a compliant riser idealized as a slender, non-rotationally uniform rod with bending, extensional and torsional degrees of freedom. This model includes the effects of external and internal pressure and speed of the internal fluid on the system.
