Definitions
- the present invention relates to a device for embedding an oil pipe termination on a load-bearing structure, in particular a platform or a boat, the termination comprising a substantially cylindrical or conical wall at the level of the part to be embedded.
- the termination is constituted by a stiffening sleeve comprising a jacket forming the substantially cylindrical wall mentioned.
- stiffening sleeves used to limit the curvature of a flexible pipe are well known, and reference may be made, for example, to patent applicants EP 0 565 445 A or FR 97 03 095.
- the embedding device When a flexible pipe, fitted with a stiffening sleeve and a ferrule is winched on a platform to be fixed by embedding, the embedding device must be built to withstand high stresses, composed of 'A part of the axial loads resulting from the weight of the submerged pipe, but above all from the bending moments exerted on the stiffening sleeve, moments which result in particular from sea currents and swell. These stresses should be appropriately included in the embedding device.
- the stiffening sleeve has at its end a large flange, which is passed through an opening in the support structure, after which two thick plates are slid under the flange.
- the plates are found astride a pedestal secured to the supporting structure. Then the plates are bolted to the pedestal and the flange screwed to the plates, bolts and screws being prestressed.
- document US Pat. No. 5,683,205 discloses an interposed sleeve system making it possible to relieve a pipe. crossing an opening of a floating structure, by distributing the forces, in particular of curvatures on the pipe. This system is not intended to fix or support the weight of a submerged pipe at a termination.
- GB 2 317 631 discloses a floating riser guide system, making it possible in particular to guide the riser along a vertical axis. It is therefore in no case a device for embedding an oil line termination.
- the object of the invention is to propose an efficient and compact embedding device.
- the invention achieves its object thanks to a device for embedding a teraiination - and in particular a stiffening sleeve - of submerged oil pipe on a carrying structure forming part of a platform or of a boat, the termination comprising a substantially wall cylindrical or conical at the level of the part to be embedded, characterized in that it comprises a substantially cylindrical or conical hollow tube fixed on the supporting structure and with an internal diameter slightly greater than the diameter of said cylindrical or conical wall, and two devices for support / centering respectively lower and upper provided at the bottom and top of said tube to cooperate with said wall in order to support the weight of the submerged pipe and to center said termination.
- the termination is winched, as known per se, until its said wall is inside said tube, whose slightly larger dimensions and the advantageous presence of an inlet funnel allow this maneuver. Thanks to the two support / centering devices located some distance from each other, it is possible to correctly align the termination with the axis of the tube and to hold it securely, using the lever arm to counter the effects of the bending moment, which is the most critical point.
- the wall of the termination can be substantially cylindrical or conical, and possibly include shoulders, the tube being substantially complementary.
- the diameter of the wall is slightly greater at the bottom so as to reduce the clearance and therefore the size of the support / centering device while allowing easy entry of the termination into the tube.
- One of the support / centering devices consists of at least one conical element cooperating with a shoulder provided on the termination with a conical bearing provided on said tube.
- the conical elements can be separate elements distributed circumferentially, or preferably consist of a collar in two parts.
- the conical bearing is provided at the upper end of said tube, and the conical collar rests there by providing both a support and a certain centering and alignment on the axis.
- the shoulder provided on the termination advantageously consists of the upper edge of an annular groove formed in the cylindrical wall and partially accommodating the conical collar.
- each projection consists of a dowel, in one or more parts, housed radially in a radial hole of the tube and which is individually forced radially inward against the tube, for example by means of a thread provided in the radial hole and on the rear part of the plug, which then forms a pressure screw.
- each retractable projection is constituted by a ball housed in an orifice opening radially into the tube.
- the forced radial movement of the ball inward is caused by a wedge housed in the wall of said tube.
- the wedge can be provided at the lower end of a pin housed in a vertical passage inside the wall of the hollow tube.
- the corner can be formed by a ramp provided on the spindle to act either up or down.
- the movement of the spindle can be actuated from the top of the device, which is the most easily accessible.
- the movement of the pins can be collective or individual.
- a hydraulic cylinder mechanism can be associated with each spindle.
- the material of the ball and that of the corner are provided so that limit their deformations when the ball is pushed out of its orifice when it creates pressure on the wall of the termination.
- the force imparted to the corner and therefore to the ball as well as the material of the wall of the termination at the point of contact with the balls are chosen so as to either create a plastic imprint in said wall during installation (by creating then a pre-stress) or on the contrary to limit such a footprint to a negligible depth during maximum stresses.
- the wall of the termination can moreover comprise at the place of contact of the balls a belt made of another material than the rest of the wall, harder or softer depending on the desired objective.
- the ball device therefore realizes a centering and, in cooperation with the upper device, an alignment of the termination, at the same time as by the pressure and possibly the insertion of the balls, it ensures a firm fixing of the termination in the device d installation.
- the ball device of the invention has the advantage of not requiring a predetermined redundant axial contact surface with the upper device and which would lead to a very strict control of the tolerances of manufacturing.
- FIG. 1 is a sectional view of the embedding device of the invention and the built-in stiffener
- - Figure 2 is a sectional view of the detail of the upper support / centering device of the embedding device
- Figure 2 A being a simplified analogous view showing a modification of the conical collar
- FIGS. 3A, 3B and 3C are sectional views of the detail of the support / lower centering device of the embedding device in three successive stages of locking
- FIG. 4 is a view in half cross-section of the detail of the support / lower centering device of the embedding device
- FIGS. 5A, 5B, 5C and 5D are side views illustrating four stages of the supply of a stiffening sleeve into the embedding device of the invention
- - Figure 6 is a view similar to Figure 1 of a mounting device of the prior art.
- the embedding device 1 illustrated is intended to embed the stiffening sleeve 2 which equips the flexible pipe 3. It could also be a matter of embedding a termination separate from the stiffening sleeve (for example situated in its extension) but having like it a substantially cylindrical or conical wall.
- the device 1 essentially comprises a hollow holding tube 4, comprising on the outside a radial flange 5 by means of which it is fixed to a support structure, consisting of beam elements 6 integral with the bridge (not shown) or the platform to which the pipe should be suspended.
- the sleeve 2 has at its end an annular plate 7, from which comes a substantially cylindrical jacket 8 covering the periphery of the sleeve 2.
- the plate 7 is fixed to the sleeve by threaded bolts 9 and thus blocks the rim of an insert 11 of the stiffener.
- the insert 11 receives the sleeve 12 of the end fitting 13, which sleeve has a fixing rib 14 which is tightened by a fixing collar 15.
- the embedding device 1 of the invention comprises two support / centering devices respectively lower 16 and upper 17.
- the upper device 17 essentially consists of a collar in two parts 18 with conical surface 19.
- the inner edge 20 of the collar comes lodge under a shoulder formed by the edge of a peripheral groove 29 formed in the upper part of the jacket 7,8, and the collar carries by its surface 19 against the conical bearing 21 which forms the upper edge of the hollow tube 4.
- the collar 18 has at its periphery, at the top of the conical surface 19, a flange 19 'which cooperates with a flange 21' formed at the top of the conical surface 21 of the tube 4, so to favor the setting in the axis of the collar 18 during its descent on the tube 4.
- a clearance "e” is provided between the flanges 19 'and 21' in the final position so as not to interfere with the cooperation of the bearings 19 and 21 .
- the lower device 16 comprises captive balls 22 (for example from 3 to 60, distributed circumferentially, the drawings representing only four) housed in the wall 4 of the hollow tube in housings formed by a cylindrical orifice 23 opening out from a side radially inside the tube 4 and communicating on the other side with a longitudinal passage 24 extending in the wall 4 to its upper end.
- the ball housing allows the ball 22 to be retained in the retracted position, entirely inside the wall 4, that is to say without protruding inside the tube .
- a pin 25 with a wedge-shaped end 26 is housed in the passage 24 above the ball 22.
- the pin 25 is driven in (either by mechanical or hydraulic means, or by the very weight of the pipe transmitted by the collar 18 on the heads of the pins), the wedge 26 pushes the ball 22 radially inwards, in the orifice 23 whose diameter is very slightly greater than that of the ball 22, except at level d 'an edge 27 intended to prevent the total escape of the ball 22.
- the ball 22 projects more and more inside the tube 4 (at most by an amount slightly less than the radius of the ball) and comes to meet the skirt 8 of the sleeve sleeve 2 in which it prints, if necessary, by deformation of the skirt, which creates an effective locking of the sleeve in the tube.
- FIGS. 5A to 5D show the approach and locking phases of a sleeve in a lashing tube 4, below which a guide funnel or trumpet 30 has been fixed, as is known per se
- the sleeve 2 is hoisted by means of the end piece 13 and a cable which is wound on the winch 32 (FIG. 5A). Because the balls 22 are retracted into the wall of the hollow tube 4, the skirt 8 of the sleeve 2 can pass unimpeded through said tube, until the rib 29 protrudes out of the tube 4 (FIG. 5B) and that the collar can be installed in two parts 18.
- the sleeve 2 can then rest in support via said collar 18 on the conical surface 19 of the end of the tube 4, the axis 34 of the sleeve being in an approaching position more and more of the axis 33 of the tube 4 (FIG. 5C).
- Coaxiality and final fixation are obtained in the final phase (Figure 5D) where the wedge pins 25 are driven in their respective passage and force the balls 22 radially inward against and, if necessary, partially in the skirt 8 of the sleeve 2.
- the bottom edge of the tube 4 and the top edge of the jacket are chamfered or rounded.
- the upper support / centering device 17 ensures the resumption of axial forces and bending moments while the lower support / centering device ensures the resumption of shearing forces and bending moments.
- FIG. 6 shows, for comparison purposes, an embedding device of the prior art.
- the sleeve 2 ' has a wide flange 7' bolted to two thick plates 40 'which have been slid under them and which are themselves bolted to a pedestal 41' linked to the supporting structure 6 '.
