Definitions
- the present invention relates to a device for transporting and laying a bridge on an oil platform operating at sea.
- Generally oil rigs at sea include a bridge carrying the equipment operating and living quarters.
- the bridge is supported by tubular pillars or legs sunk in or resting on the sea floor using hooves.
- the first is to bring the entire floating platform to the operating site and descend the legs until contact with the seabed, then, taking support on the legs, to hoist the bridge above from sea level to an altitude that puts it out of range of the highest waves.
- the second installation method is all first put the legs on the seabed and route the bridge from the platform of the assembly site to site using a transport barge of a compatible size with the size of the bridge.
- the difficulty lies in the transfer of barge deck to the upper ends of legs, because the bridge which is placed on a floating object subjected with the action of the swell, is animated in the same way as the object that supports it in an uninterrupted orbital motion the amplitude of which depends on the size of the swell.
- the bridge constitutes a very heavy mass up to several thousand tonnes which does not facilitate not the transfer of said bridge.
- the barge supporting the bridge is placed between the platform legs and transfer from the barge deck up to the legs of the platform is performed either by ballasting the barge, either by lifting means arranged on said barge.
- ballasting of the barge is a long operation which takes several hours and the lifting height of the bridge is weak which does not allow to install the bridge in rough seas because it will not be at a high enough putting it out of reach of most high waves.
- the invention aims to remedy the drawbacks known devices by proposing a transport device and laying a bridge of an oil platform which is designed to allow the transfer of this bridge over a significant height of the order of 10 to 20 meters, while allowing a significant time saving.
- the invention therefore relates to a device for transport and installation of a bridge for an oil platform operating at sea, of the type comprising a floating barge intended to support the bridge and provided with displacement means of said bridge between a support position on the barge and a support position on the legs of the platform, characterized in that it comprises a support frame of the bridge intended to be placed on a barge and comprising the means for moving the bridge formed by at least one rack vertically movable by means of drive mechanisms.
- FIGs. 1 and 2 there is shown schematically a device for transporting and laying a bridge 1 of an offshore oil platform.
- the bridge is formed by an assembly of beams metal and has at its lower part feet of positioning 2 on the upper end of legs 3 of support for the oil platform bridge.
- the bridge has a rectangular shape and the feet of centering 2 are four in number arranged at each corner of deck 1.
- the device for transporting and laying the bridge 1 includes a floating barge 10 and a support frame 11 of this bridge 1 intended to be placed on the barge and comprising means for vertical displacement of said bridge 1.
- This support frame 11 is formed by at at least one upper beam 12a and at least one lower beam 12b separated from each other and interconnected by spacers 13.
- the support frame 11 is formed by two beams upper 12a parallel, and by two lower beams 12b parallel said beams 10a and 12b being connected between them by the spacers 13.
- the beams 12a and 12b support at each of their ends the means of displacement of the bridge 1 which are formed by at least one movable rack 21 vertically by means of drive mechanisms 20.
- the assembly formed by the beams 12a and 12b and by the racks 21 and the drive mechanisms 20 constitutes a module independent of the barge 10.
- the length of the beams 12a and 12b can be adjustable to modify the spacing between the racks 21.
- each beam 12a and 12b can be constituted by half-beams placed one after the other of others and connected to each other by a system of flanges and bolts.
- the modules formed by beams 12a and 12b can be interconnected by longitudinal beams, not shown, extending parallel to the axis of barge 10.
- the installation of the bridge 1 on the barge 10 can be carried out in two ways.
- the first is to assemble deck 1 directly on the support frame 11 on a platform of a shipyard.
- the assembly constituted by the support frame 11 and said bridge 1 is transferred on the barge 10 for example by a suitable lifting device or by any other means.
- the racks 21 are then installed on the support frame 11.
- the second method is to place directly on the barge 10 the support frame 11 and to move the bridge 1 by sliding in order to transfer it from the assembly platform on said support frame 11.
- the means for moving the bridge 1 between a position support on the support frame 11 and a position of support on the ends of the legs 3 of the platform are formed by four vertically movable racks 21 by means of drive mechanisms 20.
- Each means of moving the bridge 1 is formed by a rack 21 constituted by a plate 21a (Fig. 5) comprising on each of its lateral faces a series teeth 21b.
- the plate 21a is fixed on a vertical beam 22.
- the assembly constituted by the plate 21 and the beam vertical 22 is guided by two spacers 23 which are fixed on the ends of the corresponding beams 12a and 12b and between which this assembly slides vertically.
- each rack 21 has sufficient length to allow lifting deck 1 and extends laterally from the barge hull 10.
- Each rack 21 is moved vertically by means of drive mechanisms 20 supported by beams 12a and 12b and comprising at least one designated assembly by the general reference 25 and which includes a pinion outlet 26 cooperating with one of the series of teeth 21b of the rack 21.
- the output pinion 26 is rotated by a motor 27 via at least one reduction gear 28.
- each rack 21 is formed by four sets 25 opposite two by two and each comprising a motor 27 associated with at least one reduction gear 28 driving an output pinion 26 cooperating with a series of teeth 21b of the rack 21.
- the motors 27 for driving the pinions of outlet 26 are constituted for example by hydraulic motors.
- the rack 21 has, at its upper end, a shock absorption pad 29 and the assemblies 25 of each drive mechanism are mounted in a structure 30 which is connected to the beams 12a and 12b of the framework support 11 by shock absorbing members 31.
- the pads 29 and the organs 31 for absorbing shocks are formed for example by blocks of elastomer.
- the bridge laying device 1 comprises connecting means 35 of each rack 21 with the deck 1 of the platform.
- These connecting means 35 can be separated after ballasting the barge 10 in order to prevent the ends racks 21 come up against the bridge 1 after separation of barge 10 from said bridge 1.
- the connecting means 35 are formed by a rod 36 threaded at each of its ends.
- the rod 36 has a first end 36a connected to the corresponding rack 21 by a bolt 37 screwed on the end 36a of the rod 36.
- the other end 36b of the rod 36 is connected to bridge 1 by a bolt 38 screwed on said end 36b.
- An elastic ring 38a such as for example a elastomeric material, is interposed between the bolt 38 and the deck 1.
- the rod 36 which is preferably made of metal comprises a portion 39 of reduced section intended to break under a specific load.
- the means 35 for connecting the rack 21 with deck 1 of the platform include a rod 40 of preferably metallic which has a first end 40a threaded and a second end 40b provided with a groove 41.
- the end 40a of the rod 40 is connected to the bridge 1 by a bolt 42 screwed on said end 40a and a ring 43 in elastic material, such as elastomer, is interposed between bolt 42 and deck 1.
- the end 40b of the rod 40 is connected to the rack 21 by at least one locking member 44.
- the lock 44 is formed by two opposite fingers 45, which can be moved transversely to the axis of the rod 40 and each actuated by a control member consisting of a cylinder 46.
- Each finger 45 cooperates with the groove 41 formed on rod 40.
- the end 40a of the rod 40 can be connected to bridge 1 by fingers 45 and the end 40b of said rod 40 can be connected to the rack 21 by a bolt 42.
- the means 35 for connecting the rack 21 with deck 1 of the platform include a rod 50 preferably metallic, one end 50a of which is connected to said rack 21 by a shoulder 51 formed on said end 50a or by a ring fixed on this end 50a.
- the other end 50b of the rod 50 is connected to deck 1 by means of at least one locking member 42 which, in the embodiment shown in Fig. 8, is constituted by two opposite fingers 53 and movable transversely to the axis of the rod 50.
- Each finger 53 has the shape of a corner and is actuated by a control member formed by a jack 54.
- the fingers 53 having the shape of a wedge cooperate with a groove 55 formed on the end 50b of the rod 50 and which has a section of complementary shape to said fingers 53.
- the cylinders 54 are controlled by accumulators 56 which ensure the calibrated shrinkage value of the fingers 53 under a determined tensile load on the racks 21.
- bridge 1 previously assembled on a dock of a shipyard as well as the support frame 11 are transferred to the barge 10 as shown in Fig. 1.
- Bridge 1 can be simply placed on the framework support 11 or can be connected to said frame by appropriate elements as well as by connecting means 35 of the racks 21 with this bridge 1.
- Barge 10 transports deck 1 to the site operating at sea where the 3 legs of the platform have previously laid on the seabed, as shown in Fig. 9.
- the barge 10 is moved between the legs 3 of the platform to bring the positioning feet 2 in the axis of the ends of these legs 3.
- the motors 27 of the drive mechanisms 25 are operated in reverse order to lower the bridge 1 via the racks 21 and to place the positioning feet 2 on the ends of the legs 3, as shown in Fig. 10.
- the racks 21 can be connected to deck 1 of the platform by the means of link 35 which can be separated after ballasting the barge 10.
- Ballasting of this barge 10 can be carried out in two ways.
- the first consists in ballasting the barge 10 in gradually filling it with water so as to increase his weight.
- this load 10 separates from the deck 1 either by breaking the rods 36, either by moving fingers 46 or 53 to release rods 40 or 50.
- the barge 10 sinks deeper into the water and the distance from the end superior of each rack 21 is therefore sufficient so that it does not come up against the deck 1 after separation.
- the second way to ballast the barge 10 is to lift it gradually.
- the pinions 26 are rotated by motors 27 and reducers 28.
- this barge 10 separates from deck 1 either by breaking the rods 36, either by moving fingers 46 or 53 to release the rods 40 or 50.
- the device according to the invention makes it possible to place quickly a bridge over the legs of an oil rig and move this bridge to a height of around 10 to 20 meters thanks to the significant travel of the means of displacement.
- the racks have rigidity important especially for lateral forces which avoids the installation of bulky guide members.
