ABSTRACT:
A catenary riser support tube that receives the riser and is attached to the floating offshore structure. The support tube is attached to the floating offshore structure at an angle from the vertical so as to be in line with the natural angle that the installed catenary riser would assume on a calm day. The support tube is attached to the floating offshore structure at different points along the length of the support tube and thus flexes about its attachment points to the floating structure. This minimizes stresses on the catenary riser.
