Abstract:
The present invention provides a buoyant system and method for a hydrocarbon offshore floating platform to be coupled and decoupled from a subsea buoyant extension with risers slidably coupled thereto. The buoyant system can allow rigid risers to be coupled and decoupled and alternatively move between a first elevation below the offshore floating platform, such as at the buoyant extension, and a higher second elevation at the offshore floating platform independent of a spool piece, arch support, and flexible joint for the risers. The buoyant system can reduce riser stress by reducing bending required for the riser to form a catenary or other curved shape even as a rigid riser.

Claim (Index 1):
A buoyant system configured to be detachable from an offshore floating platform, comprising:\n a buoyant extension having a buoyancy and configured to be detachably coupled with the offshore floating platform; and a first guide tube coupled to the buoyant extension and configured to allow a rigid portion of a riser to pass through the guide tube alternatively between a first elevation below the offshore floating platform and a higher second elevation at the offshore floating platform.
