Abstract

The hull (12) of a floating platform has at least one deck (14) for supporting drilling and/or production equipment above the surface of a body of water (16). A base node of the hull includes pontoons (18) extending radially 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 buoyancy 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).
