SUBSEA RISER SUPPORT AND METHOD FOR BRIDGING ESCARPMENTS

摘要

The present disclosure provides a lateral external sleeve (20) for a riser (4) that can be preinstalled or field installed around the riser as it is deployed onto the seabed (2) and a stress joint (22) installed with the riser and longitudinally partially within the lateral external sleeve. The external sleeve in conjunction with the stress joint can support a laterally deployed riser in an otherwise high stress zone of the riser as it would bend due to changes in elevations and thus reduce stress on the riser. The system can act independently of a buoy-based system typically used in the art.
