Abstract
A buoyancy system for a deep water floating platform includes at least one composite buoyancy module coupled to the a riser having a length greater than 1000 feet and an associated weight. The composite buoyancy module is sized to have a volume to produce a buoyancy force at least as great as the weight of the riser. The composite buoyancy module may include a vessel with a composite vessel wall. The buoyancy module or vessel may have a non-circular cross-section defining an area which is greater than approximately 79 percent of an area defined by a square with sides tangent to the vessel wall to maximize buoyancy. A second buoyancy module may be directly coupled to the first buoyancy module to achieve a desired buoyancy.
