Abstract
A method and apparatus is described for installing an export production riser on an offshore production platform that moves in response to ocean waves, wind and currents. The riser is provided with a catenary shape between the near vertical connection on the platform and the horizontal position on the seafloor. The upper end of the riser is maintained at a nominal inclination from the vertical to control excessive bending stresses in the riser. A flexible joint is provided at the upper end of the riser to allow rotational movement between the riser and platform as the platform moves.
