Definitions
- the present invention is based on a concept of a riser traction support system applied to a UEP.
- the mechanism of the invention may make it possible to reduce the need for shallow diving in rigid riser interconnections, promoting competitiveness with the flexible riser solution.
- the BSMF (Boca de Sino Multifuncional - PI 0902469-7), is the basic concept established for a new device for supporting risers, developed by Petrobras, which should have the versatility to allow the use of flexible or rigid risers, the interconnection may be carried out on the port or starboard side of the UEP.
- the BSMF can be considered as a first support tube approach, where the top termination of the riser, commonly called the Hang-Off Adapter (HOA), contains a flexible joint or stressjoint attached to its bottom.
- HOA Hang-Off Adapter
- the riser traction is anchored in the upper cone of the BSMF, this effort being transmitted by wedges that, in the initial development stage of the BSMF concept, would be installed by shallow diving. Lateral efforts from the riser would be supported by a locking ring located at the bottom of the support tube.
- Document US2012070225A1 discloses a connector assembly that can be used to connect a tension ring to a telescopic joint in a riser by using a lower configuration of hydraulically actuated dogs.
- a set of hydraulically actuated hang-off dogs on the connector set can be used to connect the tension ring to a platform-mounted offset structure.
- a hydraulically actuated locking ring is used to provide a positive stop against the back of the hang-off dogs.
- Document W02017034409A1 discloses a system for locking a riser in a support tube on a floating platform.
- a support tube is installed by a structural connection to the hull of a floating unit.
- the locking system has six hinges distributed around the periphery of the support tube.
- the support tube has a collar which is held by the hinges when said hinges are in the locking position.
- Document WO2014179732A2 discloses a tool used to fix the end of top risers.
- the tool has a base and a ring that is movable relative to the base, and has a plurality of couplings, each coupling having a groove.
- the tool even includes configured lugs to attach the tool to an upper unit via cables.
- An actuator is disposed between the base and the ring.
- the ring is movable relative to the base as the actuator moves between an extended position and a retracted position.
- the actuator may be a hydraulic cylinder, a pneumatic cylinder, a motor or other state of the art drive device.
- the tool includes fastening members pivotally connected to the base through a support member and a pin. The fastener is configured to rotate about the pin as the ring moves relative to the base.
- This invention presents a mechanism for retracting the wedges (8) of a rigid riser support ( Figure 2), consisting of a cone (9), a cam-holder crown (1), rods (6) with rollers ( 4), an actuating spindle (2), and springs (5), this system can be operated remotely through the hydraulic actuator (3), or activated locally by ROV, thus dispensing with the diving activity.
- FIG. 2 which illustrates a general view of the automated retraction mechanism of the wedges installed on the upper cone of the support tube, with indications: camshaft crown (1), drive spindle (2), hydraulic actuator (3), rollers ( 4), springs (5), rods (6), wedges (8), cone (9), and cams (10);
- the mechanism for retracting the wedges (8) of a rigid riser support ( Figure 2) consists of a cam-holder crown (1), rods (6) with rollers (4), an actuating spindle (2), and springs (5), this system being able to be actuated by ROV, dispensing with the diving activity.
- the drive spindle (2) can also be replaced by a hydraulic actuator, which can be operated by a panel installed in the UEP itself, also dispensing with the use of ROV for the activities of activating the support.
- the system makes it possible to move the wedges remotely during pull-in and pull-out operations. It is also possible to use the system in the preparation phase for the pull-in, since it allows activation for tests and cleaning of the handling surfaces.
- Figure 2 shows the concept overview of the new engine.
- Camholder crown (1) component responsible for moving the wedges (8). When driven by the spindle (2), the crown (1) rotates around its axis, thus simultaneously moving all the rods (6) through the rollers (4) following the cams (10). The geometry of the cams was defined so that at the beginning of the rotation movement of the crown, the force exerted on the rods (6) is greater, in order to avoid possible locking of the wedges in the working position. After the beginning of the movement, it is expected that the effort required to move the wedges will be progressively smaller. [0018] Drive spindle (2): component driven by ROV through a suitable interface, which transmits to the crown (1) the torque necessary for its rotation and consequent movement of the wedge system. This component can only be mounted when there is a need to drive the system by ROV.
- Hydraulic actuator (3) responsible for transmitting to the crown (1) the torque necessary for its rotation and consequent movement of the wedge system (8). This actuator enables the remote activation, through a panel in the UEP, of the locking system.
- Rollers (4) components installed on the rods (6) that follow the cams (10) mounted on the crown. This component transfers the rotation movement of the crown (1) to the translation movement of the rods (6), which in turn move the wedges.
- Springs (5) help the return of the wedges to the working position, in case there are deposits of marine life that prevent the return by gravity.
- Rods (6) transfer the translation movement to the wedges.
- the present invention is able to provide economic and productivity advantages, enabling the reduction of time to start oil production and the waiting time of vessels for pull-in activities. Another advantage is related to health and safety, which is achieved by eliminating shallow diving activities during pull-in and pull-out operations of rigid risers. Finally, the system of this invention (remotely activated camshaft crown) allows testing and cleaning of wedges before pull-in, increasing the reliability of the operation.
- Figure 5 shows the system with the wedges retracted for testing and cleaning, during the pull-in operation.
