Abstract

A riser connector assembly (4) for a plurality of risers (1) attached to a floating production vessel (2), comprising clamps means for holding and retaining the ends of a plurality of risers (1) with the ends of the risers spaced and arranged to link with mating inlets (3) on the production vessel (2). and buoyancy means (4) for supporting the assembly when released with attached risers at a location below the surface but above the seabed.
