摘要： The present invention presents a mechanism for retracting the wedges of a rigid riser support, consisting of a cam holder crown (1), rods (6) with rollers (4), a drive spindle (2), a hydraulic actuator (3) and springs (5); this system can be driven by ROV or remotely. The invention 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.

摘要： The present invention presents a riser support completely integrated into the Riser Balcony of an FPSO, which serves both rigid and flexible risers. The basic concept established for this new riser support presents a versatility that allows the use of flexible or rigid risers with some variation in their inner diameters and the interconnection can be carried out on the port or starboard side.
The Diverless Unified Support Tube (DUST), object of this invention, is characterized in that it comprises an upper cone (1), a guide tube (2) and a centralizer (3), responsible for centralizing the hang-off adapter and locking the bend stiffener (11). The application of DUST can promote a reduction in the length of rigid pipes in the subsea arrangement by allowing keelhauling interconnections, in addition to enabling the optimization of the rigid riser interconnection operation and accelerating the Ramp-up of new SPUs.-

摘要： The present invention consists of a launching method consisting of lowering a reel drive system, suitably marinized, to a fixed distance from the seabed, close to 50 m (enough to avoid colliding with obstacles and subsea systems), thus minimizing the catenary formed during the launch or recovery.
The proposed equipment is capable of rotating standard reels containing flexible pipes and umbilicals, with rotation and torque control, as well as control of the flexible ends (through an auxiliary winch system), designed so that the entire system can be lifted by winches from a vessel and lowered to a working depth, close to the seabed.
