Abstract
There is provided a buoyancy system for a structure having at least one component being substantially stationary with respect to the bottom of a water covered area. The system comprises a set of buoyancy modules of engineered materials to apply an identified amount of buoyancy. The set of buoyancy modules is attached to the structure at a set of buoyancy load transfer locations. The set of buoyancy modules comprises layers of the engineered materials. The engineered materials comprise a substantially reinforced axial layer, a substantially reinforced hoop layer; and a leak prevention layer.

A buoyancy system for a structure having at least one component being substantially stationary with respect to the bottom of a water covered area, the system comprising a set of buoyancy modules of engineered materials to apply an identified amount of buoyancy;
- the set of buoyancy modules being attached to the structure at a set of buoyancy load transfer locations.
Apparatus for providing buoyancy to a submerged riser attached at its lower end to a well head on the sea floor;
- which comprises:
- a plurality of submerged buoyancy modules associated with the riser for imparting an upward buoyancy force to the riser, wherein each buoyancy module is hollow and has an elongated shape with a longitudinal axis and is vertically oriented, the longitudinal axis of the buoyancy module being generally parallel to the longitudinal axis of the riser, some of the buoyancy modules being disposed at different vertical elevations along the riser in an arrangement so as to provide improved hydrodynamic performance to the riser, each buoyancy module providing a small fraction of the total buoyancy from all the modules for purposes of redundancy;
