• Description:
  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. A compliant riser is allowed to accrue large static deformations because of its small bending rigidity. The riser readjusts its configuration-​-​without excessive stressing--in response to the large, slow motions of the supporting platforms it is connected to. This work presents a mathematical model for the three-​dimensional non-linear static and frequency domain dynamic analysis of nonrotationally uniform compliant risers with torsion in the presence of three types of forces: unidirectional monochromatic waves traveling at an arbitrary angle; arbitrary monochromatic motions and rotations of the upper and lower ends of the riser, of the same frequency as the waves; and arbitrary currents.
