Abstract

A catenary riser system for use in water to bring a riser from seabed equipment (1) to a production vessel (2) at the surface, the system comprising an upper portion made of flexible pipe and a lower portion, the two portions being joined at a releasable and rejoinable connector, the lower portion being designed to form a J-shaped catenary between the seabed equipment and a support (3) at a level intermediate the seabed and the surface, the upper portion being designed to pass over the support (3) and form a U-shaped catenary between the support (3) and the production vessel (2), and at least the part of the connector attached to the lower portion being arranged to be held by the support (3).
