Abstract

See full text

A method and apparatus is presented for connecting a flexible conduit bundle from a subsea wellhead to a floating platform. Movement of the floating platform relative to the subsea wellhead is compensated for by arranging the conduit bundle to be suspended in a catenary manner between the wellhead and the floating platform. The catenary form of the conduit bundle is maintained by bending the circuit around anchor blocks located a selective distance from the subsea wellhead.
