Abstract

An underwater steel catenary pipeline riser (SCR) lifting frame comprises a lift frame foundation and an SCR lifting frame comprising a lift frame interface adapted to be connected to the lift frame foundation; a foundation interface; a lift guide configured to accept the lift frame foundation; and a lift slidably disposed about the lift guide, the lift comprising an SCR pull head interface configured to be connected to an SCR pull head. The underwater steel catenary pipeline riser (SCR) lifting frame 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.
