Disclosed is conduit anchor, an offshore system comprising a conduit anchor and a method of deployment. The conduit anchor includes a base section adapted for attachment to a conduit, and a conduit guide extending from the base section. In use a dynamic conduit extends along a dynamic conduit pathway range defined by the anchor, via the conduit guide. The conduit guide comprises a convex bend protecting surface region oriented towards the dynamic conduit pathway range which in use protects against over bending of the dynamic conduit.

The invention provides a jumper termination apparatus for a subsea jumper flowline, a flow system incorporating a jumper termination apparatus, and a method of use. The jumper termination apparatus comprises a body, a jumper coupling means configured to couple the body to a jumper flowline, a connector coupling means configured to couple the body to a subsea manifold connector, and an access interface disposed on the body, arranged above the connector coupling means and vertically oriented to enable access from above. The body defines a first flow path from a coupled jumper flowline to a coupled subsea manifold connector, and a second flow path from the access interface to the first flow path or the subsea manifold connector. The access interface is configured to be connected to a termination apparatus of a second jumper flowline in a vertically stacked arrangement.

A method of laying an off-shore pipeline (1) comprises: —installing on the seabed (3) a fixed receiving structure (4) having a redirecting device (5), —paying-out from a laying vessel (7) a pipeline (1) with the pipeline end termination device (9) vertically towards the seabed (3), —extending a damping cable (6) from the pipeline end termination device (9) through the redirecting device (5) to an underwater damping buoy (14), —connecting an underwater suspension buoy (15) to the pipeline end termination device (9), —inclining the pipeline (1) from a vertical orientation towards the horizontal orientation, using: —the suspension buoy (14) to counterbalance at least part of the weight of the pipeline end termination device (9), —the damping buoy (14) for damping the pipeline (1).

A system for processing oil and gas at an offshore facility includes a single stage separation module. A gas stream from the single stage separation module is pressurized in a primary compressor, and then is used to heat the incoming oil and gas upstream of the single stage separation module. Flash gas from treatment of an oil stream from the single stage separation module is pressurized in a flash gas compressor and then is used to heat glycol utilized in a gas dehydration unit. The pressurized flash gas is then commingled with the gas stream from the single stage separation module upstream of the primary compressor.

A modular floating platform system includes a detachable floating buoy providing a body tethered to a seafloor with a plurality of mooring lines and coupled to a subsea production system via one or more communication lines, and a plurality of floating surface facilities, each floating surface facility providing a standardized bottom interface matable with the detachable floating buoy. A latching mechanism individually couples each floating surface facility to the detachable floating buoy when each floating surface facility is individually mated to the detachable floating buoy. One or more communication couplings place each floating surface facility in communication with the subsea production system via the one or more communication lines when each floating surface facility is individually mated to the detachable floating buoy.

Rigid riser adapter operable to be at least partially installed into a lower riser balcony. The rigid riser adapter includes a receptacle support structure. Additionally, the rigid riser adapter also includes an adapter tube extending from the receptacle support structure substantially along a vertical direction, the adapter tube operable to be inserted through a lower riser balcony. The rigid riser adapter can also include a rigid riser receptacle coupled to the receptacle support structure, wherein the rigid riser receptacle is angled between six degrees and twenty degrees in relation to the vertical direction.

The present invention provides a system for coupling between a bend stiffener (1) and a bell month (2) comprising a plurality of locking mechanisms (3), wherein each locking mechanism (3) is secured externally to the bell mouth (2) and comprises a movable lug (30) positioned such as to slope downwards, in which the lug (30) accesses the interior of the bell mouth (2) and is actuated by an elastic element (34) designed to exert pressure on the lug (30) in the direction of the interior of the bell mouth (2).

The present invention proposes a device capable of allowing remote unlocking operation and remaining compatible with the possibility of a mechanical and manual drive. The device is a hydraulic actuator (2) with hydraulic power supply through the lines coming from the platform. It also has a handle (4) for manual driving.

The invention allows cost reduction with PLSVs (waiting for diving and standby weather) and with diving activities themselves, in addition to greater agility in pull-out operations. Further, it promotes the diminishment of the need for diving and, consequently, lower MHRE (Man-Hour of risk exposure).

A subsea riser is installed by lowering at least one riser conduit to the seabed when piggybacked to an elongate support that comprises at least one flowline. The elongate support may be a pipeline bundle, which may be attached to one or more towheads in a towable bundle unit. The riser conduit may be in fluid communication with the flowline. At the seabed, a free end portion of the riser conduit is detached from the elongate support by releasing subsea-releasable fastenings. Then, with the elongate support and a root end of the riser remaining at the seabed, the detached free end portion of the riser conduit is lifted away from the elongate support to a riser support, such as a platform, an FPSO (floating production, storage and offloading vessel), or a buoy.

A subsea catenary riser comprises a rigid riser pipe that is suspended from a floating support on the surface and extends through a sagbend to the seabed. A hang-off interface allows rotation or pivoting of the riser pipe relative to the support about mutually orthogonal horizontal axes. A subsea buoy is positioned on the riser pipe above the sagbend. The buoy applies buoyant upthrust force to the riser pipe via an attachment interface that allows rotation or pivoting of the riser pipe relative to the buoy about mutually orthogonal horizontal axes. In response to movement of the support, the riser pipe deflects with S-shaped curvature to vary the inclination, relative to the buoy, of the portion of the riser pipe to which the buoy is attached. The curvature comprises mutually opposed curves respectively above and below the buoy, joined by a region of inflection that coincides with the buoy.
