Abstract
Disclosed is a mechanism for retracting the wedges of a rigid riser support, consisting of a cam holder crown, rods with rollers, a drive spindle, a hydraulic actuator and springs; this system can be driven by ROV or remotely. The system allows the reduction of the need for shallow diving and enables interconnections of rigid risers by keelhauling, promoting competitiveness with the flexible riser solution.
