摘要： A riser assembly and method of installing a riser assembly are disclosed. The riser assembly includes a first attachment element connected to a first portion of flexible pipe and a second attachment element connected to a second portion of flexible pipe. The first attachment element and second attachment element are connected by at least one tether element, via a fixed structure in a configuration such that, in use, in response to movement of the first and second portions of flexible pipe, the tension load at any moment in time, at each attachment element, remains substantially equal.

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.
摘要翻译：本公开内容提供了用于立管的侧向外部套筒，当其被部署到海床上时可被预安装或现场安装在立管周围，并且应力接头与立管安装在一起并且纵向部分地在侧向外部套筒内。结合应力接头的外部套筒可支撑立管的其他高应力区域中的侧向展开立管，因为它会因立面的变化而弯曲并因此减小立管上的应力。该系统可以独立于本领域中通常使用的基于浮标的系统而行动。

摘要： A subsea flexible riser installation has a seabed foundation and a steep-configuration flexible riser anchored to the seabed by the foundation. An attachment formation is fixed relative to the riser and a locating formation is fixed relative to the foundation, both at positions elevated above the seabed. The locating formation is engaged with the attachment formation on the riser. This holds the attachment formation and the riser against movement when engaged, protecting the base of the riser from over-bending and fatigue.

摘要： A flexible pipe system for transferring fluid between a seabed installation (7) and a sea surface installation (6). The flexible pipe system comprises a fixed subsea structure (2) with a support section (3) and a flexible transporting unit (1 ) with an axis along a length thereof, a sea surface end (4) and a seabed end (5) arranged with a horizontal distance and a vertical distance. The sea surface end (4) is connected to the sea surface installation (6) and the seabed end (5) is the touchdown point on the seabed of the flexible transporting unit (1 ) or the point along the flexible transporting unit (1) where it is connected to the seabed installation (7) which ever has the shorter horizontal distance to the sea surface end (4). The flexible transporting unit (1 ) is supported by the support section (3) of the fixed subsea structure (2) at a flexible pipe supporting area (1a) defining a flexible transporting unit sea surface length (1b) extending along the flexible transporting unit (1) from its sea surface end (4) to the flexible pipe supporting area (1a). At least a section of the flexible transporting unit (1) is movable along the axis with respect to the support section (3) of the fixed subsea structure (2) such that the flexible transporting unit sea surface length (1b) can very between a minimum and a maximum length.
