Definitions
- the present invention is based on the development of a solution for supporting rigid and flexible risers.
- the basic concept established for this new riser support device was that the BSMF aimed, among other characteristics, at the versatility of allowing the use of flexible or rigid risers with some variation in their internal diameters, and that the interconnection could be carried out by port or starboard of the UEP.
- An overview of the BSMF and its main components is represented in Figure 1.
- the interface of the BSMF with the top termination of the riser depends on the technology adopted (rigid or flexible riser). that of the flexible ones, by the inferior one.
- 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 diving shallow.
- the lateral forces coming from the riser would be supported by the locking ring, also highlighted in Figure 3.
- the Riser Modular Support Tube (RoST) ( Figure 7) was developed as the Minimum Viable Product (MVP) to enable the interconnection of rigid risers by keelhauling, with a minimal impact on the design of an FPSO, contemplating a double flanged tube - guide tube.
- MVP Minimum Viable Product
- a device called Upper Cone is connected, contemplating a system of sliding wedges for locking the top termination of the riser and subsequent support of the traction load of the riser (BR 10 2020 010231-1).
- a device called centralizer is connected, which is responsible for the lateral locking, presenting a function corresponding to the locking ring of the BSMF concept (see Figure 3) and the consequent stabilization of the top termination of the riser.
- RMoST The biggest limitation identified in the use of RMoST is that this is a dedicated support only for the interconnection of rigid risers.
- Document WO2019232605A1 discloses a coupling system between a curvature stiffener and a bell mouth comprising a plurality of locking mechanisms, where each locking mechanism is externally attached to the bell mouth, also containing a movable tongue positioned so inclined downwards, in which the tongue accesses the inside of the bell mouth and is activated by an elastic element adapted to exert pressure on the tongue towards the inside of the bell mouth. Furthermore, the locking mechanism comprises a reaction block (35) on which the elastic element (34) is seated.
- WO2021048592A1 discloses a rigid riser support having locking mechanisms, comprising one or more tongue portions protruding into an inner surface of the annular side wall and adapted to cooperate with corresponding hook portions formed on an outer surface of the coupling adapter, so as to produce a shaped coupling between the tongue portions and the hook portions.
- the support also features a structure similar to a “reel”.
- Document US20070056741A1 discloses a support for a Steel Catenary Riser (SCR) on a floating structure, comprising a receptacle connected to the floating structure; a flexible support tube that surrounds the SCR and sized to support the SCR while allowing the SCR to bend, a pivoting mechanism in the support tube that secures the support tube in the receptacle to allow the support tube rotate relative to the floating structure.
- the pivot mechanism includes a locking mechanism that is selectively operated to lock the pivot mechanism within the receptacle.
- the prior art presented does not provide a riser support device capable of being versatile and allowing the use of flexible and/or rigid risers with varying internal diameters.
- the present invention presents a support for risers, completely integrated into the FPSO's Riser Counter, which serves both rigid and flexible risers.
- the Diverless Unified Support Tube (TSUDL) ( Figure 8) is equipped with an upper cone (1), a guide tube (2) and a centralizer (3).
- FIG 8 shows an overview of the Diverless Unified Support Tube (TSUDL).
- the TSUDL can be separated into three macro components: the upper cone (1), responsible for supporting the rigid riser, the guide tube (2), responsible for promoting integration with the FPSO riser balcony (see Figure 9), and a centralizer (3), responsible for centralizing the hang-off adapter on the rigid riser support, through the MTL (10), and for containing the curvature stiffener locking system (11).
- the TSUDL was developed as a single solution completely integrated with the FPSO Riser Counter project ( Figure 9 and Figure 10). This led to a large reduction in the total length of the TSUDL compared to the RMoST, with an order of magnitude similar to that of the BSMF, which allowed compatibility with the support requirements of flexible risers.
- the upper cone initially designed for the RMoST was improved, making it automated, and the centralizer system (3) was improved by the inclusion of Lateral Locking Modules - MTL (10), systems hydraulics that stabilize the lateral efforts of the rigid riser.
- the TSUDL considered an adaptation of the Diverless Bell Mouth - BSDL (BR 10 2018 011452-2), considering the use of its curvature stiffener locking system (11). Further details of each of the components of the invention will be presented below.
- the TSUDL considers two macro components to support a rigid riser: an upper cone (1) and its subcomponents to support the riser traction, and a Lateral Locking Module - MTL (10 ) to provide lateral locking of the riser.
- the upper cone (1) of the TSUDL was improved mainly in the automation of the system and consequent reduction in the need for human intervention; that is, making the upper cone (1) a diverless device.
- FIG 11 A better view of the Upper Cone (1) is shown in Figure 11.
- the effective support of the riser traction is performed by wedges (4).
- the top termination of the riser (15) makes contact with the wedges (4) in its lower part, and these slide through the upper cone (1) in an upward movement guided by rods (7 ), returning to its working position by the effect of gravity and force of springs (14).
- the riser traction support is completed ( Figure 12).
- a series of lateral locking modules (10) are hydraulically or ROV/diver actuated to eliminate slack with the riser top termination (15), thus securely supporting the riser.
- the MTL (10) ( Figure 13) consists of a conical mandrel that, when advancing towards the center of the TSDUL, compresses four shoes against the outer ring, resulting in the locking of the set in any position in the approach stroke, regardless of hydraulic pressure .
- the cam ring (5) is rotated on its coincident axis of the upper cone (1). This movement is primarily performed by the hydraulic actuator (8), a resident component in the TSUDL project, or alternatively by the ROV actuator (9), a tool that can be installed by the ROV in case of failure of the first actuation method, or by any other difficulty. With the rotation of the cam ring (5), the cams (6) promote the pulling action of the rod (7), thus retracting the wedges (4) and allowing the removal of the top termination of the riser (15).
- FIG. 15 The main components of the TSUDL curvature stiffener locking system (11) are shown in Figure 15, showing an external view (left) and a cross-sectional view (right), indicating internal details of the mechanism.
- the support of the curvature stiffener helmet (16) is performed by pawls (17), these and the entire locking mechanism being confined inside a block called pawl holder (18).
- the tongues (17) retract for the passage of the helmet (16), and its automatic return to the extended position is carried out by springs (19) accommodated in the reaction block (20).
- the eccentric mechanism (21) containing a handle (22) can be operated by ROV (or alternatively by shallow diving, in case of difficulties) to retract the bolt (17).
- the grab ring (13) provides a fixed point for the ROV to stabilize its movements through a manipulator, while the other acts on the handle (22).
- a clamp (12) having pins prevent the movement of the handle (22), and these pins have a suitable interface for unlocking by ROV (or alternatively by shallow diving, in case of difficulties).
