Abstract

The hull (12) of a floating platform has at least one deck (14) for supporting drilling and/or produc-tion equipment above the surface of a body of water (16). A
base node of the hull includes pontoons (18) extending ra-dially outwardly of the hull. The platform being secured to a sea bed by anchoring tendons (20) to the pontoons (18).
A column extension (22), in the form of a closed cylinder, provides a buoyancy module (32) to the lower end of the hull (12). A mounting post (24) may be pre-installed about the periphery of the hull (12) in order to attach the buoy-ancy module (32) to the hull (12). Riser hangers (33), for attaching at least one riser or flow line (34) to the column extension/buoyancy module (22)/(32).
