Abstract: The present disclosure provides a lateral external sleeve for a riser that can be preinstalled or field installed around the riser as it is deployed onto the seabed and a stress joint 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.

Abstract translation: 本公开提供了一种用于提升管的侧向外部套筒，其可以预先安装或围绕提升管现场安装，当其布置在海床上时，以及安装有提升管并且纵向部分地在侧向外部套筒内的应力接头。 外部套筒与应力接头一起可以支撑在提升管的另外高应力区域中的横向展开的立管，因为它将由于高度的变化而弯曲，从而减小了提升管上的应力。 该系统可以独立于本领域通常使用的基于浮标的系统。
