Abstract: An underwater steel catenary pipeline riser (SCR) lifting frame (1) comprises a lift frame foundation (10) and an SCR lifting frame (20) comprising a lift frame interface (21) adapted to be connected to the lift frame foundation; a foundation interface (50); a lift guide (30) configured to accept the lift frame foundation; and a lift (32) slidably disposed about the lift guide, the lift comprising an SCR pull head interface (31) configured to be connected to an SCR pull head (131). The underwater steel catenary pipeline riser (SCR) lifting frame (1) and systems using it allow for flex joint repair/replacement subsea which do not require large winches, deck re-enforcements, steering winches, and heavy crane lifts required by facility mounted winches above water and also reduces required heavy lifting and overall complexity of flex joint replacement.

Abstract: A flexible line installed between a platform and a subsea structure. The flexible line comprises a plurality of pairwise coupled tubular sections including a first section. At least one of the plurality of sections is disposed between the first section and the platform. The first section comprises a conduit for transporting fluid between the subsea structure and the platform, an annulus surrounding the conduit, and an access device configured to provide fluid communication between the annulus and a measurement device for integrity monitoring of the first section, wherein the annulus is sealed to prevent fluid communication between the annulus and any annulus of an adjacent section of the flexible line.

Abstract: A marine riser assembly (50) includes a first riser (60) having an upper end coupled to a floating offshore structure (20) and a lower end disposed subsea. In addition, the marine riser assembly includes a second riser (70) having an upper end coupled to the floating offshore structure (20) and a lower end disposed subsea. Further, the marine riser assembly includes a riser interface assembly (100) coupled to a subsea blowout preventer (14), the lower end of the first riser, and the lower end of the second riser. The subsea blowout preventer (14) is disposed at an upper end of a subsea wellbore (19). The first riser (60) and the riser interface assembly (100) are configured to provide access to the wellbore (19) through the subsea blowout preventer (14). The second riser (70) and the riser interface (100) are configured to provide access to the wellbore (19) through the subsea blowout preventer (14).

Abstract: An improved flexible joint elastomer protection tool is described, which can be actuated and removed by a remote operated vehicle ("ROV"), the tool having pivot arms that can be rotated from a closed position to an open position. Rotation inward to the closed position results in the compression of the elastomeric component in an offshore flexible joint. Rotation outward to the open position results in the de-compression of the elastomeric component in an offshore flexible joint. Rotation of the arms can be accomplished using mechanical, hydraulic or other mechanisms that can be operated by an ROV.
