Definitions

  • the present invention relates to a new method for producing a modular system for floating constructions intended to be used offshore, this system comprising a group consisting of several cylinders.
  • the present invention provides a method for producing a modular system which can be used in particular offshore, this system comprising a group of cylinders rigidly connected to each other, this group comprises at least one central cylinder and a plurality of peripheral cylinders.
  • the method according to the invention makes it possible to quickly and inexpensively produce modular systems that can be used offshore.
  • the assembly consisting of the first two cylinders can be launched by ripping with or without the use of a barge.
  • the main cylinder comprises several cylindrical elements, these can be assembled with one another directly to said first peripheral cylinders as well as possibly to said first peripheral cylinders.
  • the method according to the invention when it applies to the case of a main cylinder comprising equipment, may comprise the mounting of said equipment on the cylindrical elements of the main cylinder before assembling them together.
  • the method according to the invention may include the assembly of an annex cylinder to said two peripheral cylinders.
  • FIG. 1 represents a type of the modular system, in this case a production platform, which can be assembled according to the method described in the present invention.
  • the reference 1 designates the platform as a whole. This comprises a main metallic flotation cylinder A ,, adapted to occupy a vertical position in service, the bottom of this cylinder being located below level 2 of the water. The upper part of cylinder A emerges in service above the water level and supports a bridge 3.
  • the main flotation cylinder A is surrounded by at least one ring of peripheral metal cylinders A 2 , A 3 ... which descend below the cylinder A ,. This arrangement gives off under the buoyancy cylinder A, a free space E limited by the peripheral cylinder crown A 2 , A 3 ...
  • this free space E could be used to place there organs such as an annex cylinder 4, making it possible to increase the rigidity of the system and / or to accommodate any ballast therein.
  • FIG. 1 shows the start of assembly operations.
  • FIG. 2 represents a peripheral cylinder A 4 comprising two elements 5 and 6 which are placed on cradles 7 and assembled together, in particular, by welding.
  • the reference 8 designates a quay and the reference 9 a basin.
  • FIG. 3 represents two first peripheral cylinders A 4 and A5 which are assembled together and placed on a cradle 10. This cradle is possibly placed on elements 11 of sliding or rolling which will facilitate, when the time comes, the launching of part of the system.
  • the main cylinder A 1 is assembled with these first two cylinders A 4 and A s .
  • This operation can be carried out by placing the cylinder A directly on the peripheral cylinders A 1 and A 4 or by gradually assembling the various elements B 1 , B 2 , B 3 ... B n which constitute this main cylinder A 1 , as well as this is shown in Figures 5 and 6.
  • FIGS. 4A, 4B and 4C show an advantageous method of assembling the main cylinder A,.
  • the subassembly thus formed B 3 , B 4 and 13 is transported by a crane 14 and is assembled with the first peripheral cylinders A 4 and A s and with the part already in place of the main cylinder B 1 , B 2 .
  • the different cylinders can be assembled together by means of connecting members 15 which may be weldable.
  • the ring of peripheral cylinders A 2 , A 3 ... is rigidly fixed by welding to the main cylinder.
  • FIG. 6 shows the assembly made up of the first two peripheral cylinders A 4 and A s and of the main cylinder A 1 .
  • This assembly can be fitted with a reinforcing member, such as an auxiliary cylinder 16, serving to stiffen the final structure (Fig. 7).
  • a reinforcing member such as an auxiliary cylinder 16 serving to stiffen the final structure (Fig. 7).
  • Ramps 17 are put in place, they connect the platform 8 to a barge 18 (Figs. 7 and 8).
  • the cradle 10 supporting the assembly A 1 , A 4 , A s is moved, possibly by ripping, to be placed on the barge 18.
  • Peripheral cylinders A 3 and A 6 can be assembled to the assembly consisting of the first two peripheral cylinders A 4 and A s and of the main cylinder A 1 , so as to ensure better stability in water for the new assembly thus constituted ( Fig. 10)
  • the barge can be turned 180 ° to allow the establishment of these peripheral cylinders.
  • the barge 18 is then tilted or possibly submerged by ballasting or ballasting in order to allow the launching of the new assembly A 1 , A 3 , A 4 , A 5 , A 6 (Fig. 11).
  • the barge is tilted laterally. It is obvious that said tilting can be effected in another direction, in particular longitudinally.
  • this system can advantageously be carried out by towing the group of cylinders (Fig. 2) and the bridge floated separately, for example by barges.
  • the group of cylinders is tilted to the vertical position and the connection to the site is then made between the bridge remaining horizontal and the cylinder assembly in the vertical position.
  • This connection can be made by ballasting certain cylinders by placing the bridge vertically on the main cylinder, then by deballasting these cylinders.
