Definitions
- the invention applies to a device for setting up a marine platform on its support structure previously installed, said platform comprising support piles intended to rest on the feet of the support structure, and comprising the means for approaching said support stacks towards said feet, each stack comprising a centering means associated with a damping member and with a sliding means controlling the centering means with respect to the stack.
- Such a device is known, for example, from French patent application No. 2 404 074.
- the invention therefore applies to any platform intended to be placed on a fixed structure preinstalled and which is subjected at the time of its installation on said structure to the action of the swell, either that the platform is itself directly floating, either it is transported by a barge, or it is suspended from the hook of a crane barge, etc.
- the platform comprises piles which at the end of the operation must rest on determined locations of the support structure and which must be welded to this structure.
- the object of the present invention is therefore to make it possible to lay the platform without risking damaging it as a result of impacts due to swell and to weld the platform to its support structure in very good conditions.
- the invention therefore relates to a device for the establishment of a marine platform on its support structure previously installed in accordance with the preamble above characterized in that each stack is constituted by a tube inside which is placed a pin, the lower part of which has a centering pin projecting below the lower end of the pile, the pin being associated with said damping member, and by means of controllable sliding of the pin in the pile, and each foot comprising at its upper part a centering and support cone of the pinoche.
- said sliding means comprises a jack.
- the jack is associated with a set of removable shims making it possible to transfer the efforts of the jack to them.
- said means for approaching said stacks comprise a mechanism allowing the relative movement of the platform relative to its stacks.
- the damping member is constituted by a mass of an elastic material.
- FIG. 1 there is shown schematically and partially a platform 1 carried, in the particular case of the example described, by a transport barge 2.
- This structure comprises feet which emerge, for example four, the figure of which shows one of them 4 having at its top a centering cone 5.
- Each leg 4 corresponds to a stack 6 secured to the platform 1.
- the platform comprises conventional means 7 making it possible to vertically move the stack 6 relative to the platform 1 and to block the stack in a fixed position. This stack is intended to bear on the top 21 of the foot 4.
- the stack 6 is constituted by a tube inside which is located a damping block 8, for example made of elastomer.
- the damping block 8 is surmounted by a tube 9 bearing against shims 10 and the shims 10 against stops 11 integral with the stack 6.
- the shims 10 can be put on and removed via a jack 12 which does not therefore undergoes only momentary efforts.
- Below the damper block 8 is located a pin 13 connected to the tube 9 by a chain 14 passing through an orifice 15 of the damper block 8.
- the pin 13 is terminated by a centering pin 16 and it is guided at 17. Low stops 18 limit the descent of the pin 13.
- a light 19 is formed at the top of the stack 6 and makes it possible to place and remove the shims 10.
- the assembly constituted by the jack 12 and the shims 10 thus makes it possible to slide the pin 13 in a controlled manner in the stack 6.
- Final docking is carried out by means of the jack 12 by putting it under pressure so as to remove shims 10 over a height corresponding to the clearance 20 plus the difference in length between the free and compressed damper so as to be found in the position of Figure 4 where there is more play, the stack 6 resting on the foot 5 and where the damper 8, being relieved, returned to its original height. It only remains to carry out the welding between the foot 5 and the stack 6 and to hoist the platform 1 onto the stack by means of the lifting machine 7.
- a particularly advantageous advantage resulting from the possibility of sliding the pin 13 in a controlled manner in the stack 6 thanks to the jack 12 and the wedges 10, in addition to allowing the final docking of the stack 6 against the foot 4 without shock, consists in the fact that this possibility makes it possible to weld the battery 6 to the foot 4 while the entire load of the platform does not rest on the upper part 21 of the foot 4. This possibility makes it possible welding under very good conditions. For this, it suffices to perform this welding before fully decompressing the damper 8 or even when the clearance 20 is not yet zero.
- the lower end of the stack 6 is provided with a forming system 22 serving incidentally as a guide for the pin 13.
- This forming system is for example constituted by a solid conical piece.
- the receiving cone 5 is mounted resiliently in the foot 4 by means of a shock absorber 23.
- a stop 24 limits the stroke of the centering cone 5.
- the centering cone 5 comes in stop for a load lower than the load of the platform.
- the centering cone 5 is retracted, the upper end of the foot 4 is free and the forming system 22 can penetrate this foot 4.
- the clearance 20 FIG. 3) between the two cham- bers is reduced on demand so as to be able to make a full penetration weld, the forming system 22 then serving as a weld support.
