Claim 7:
8. A support for risers, the support comprising:
a riser interconnection component in at least one pipe support with a rigid riser support mechanism as an integral part of an upper cone; and
a top termination of the riser (TTR) with no moving components, the top termination of the riser comprising:
a riser pre-alignment profile;
a slips support region;
a spherical geometry region for initial TTR entry;
an hourglass-shaped region for minimization of pull-in forces;
a conical surface for gap suppression & final alignment; and
a cylindrical surface for transmission of shear force to the pipe support and a stiffness transition device between a riser extension and the TTR.
