  • the floats are intended to be partially immersed with the platform so as to ensure the lift.
  • This intervention is particularly expensive because it requires, especially in the case of large platforms, to have significant lifting means, all the more important that the floats are pierced and / or that they are likely to contain significant amounts of water and that their weight opposes the lifting of the platform.
  • the invention overcomes this disadvantage by proposing an intervention barge allowing the replacement of the floats of such floating platforms in situ, these remaining immersed.
  • the invention also relates to a method of extracting or inserting a float received in a compartment of a floating platform comprising a substantially longitudinal tubular platform structure which delimits substantially parallelepipedic cages forming the compartments,

  • This configuration makes it possible to reduce the points of contact between the central element 28 of the reservoir 12 and the compartment 18, as well as the risks of jamming of said element 28.
  • the float 12 could be made of another material, for example in the form of a tank made of plastic material, or be made in a welded mechanical design having another form compatible with the shape of the compartment 18.
  • the securing means comprise high coupling means in the vertical direction comprising at least a first high element integral with the platform and at least a second upper element 32 complementary moved by a device 34 of vertical jack carried by the barge 10.
  • the securing means also comprise low hooking means in the vertical direction comprising at least a first lower member 36 integral with the platform 14 and at least one second base member 38 integral with the complementary barge 10.
  • the upper and lower hooking means successively allow the approach of the barge 10 to the contact of the platform 14 as shown in FIGS. figures 3 and 8 each second high element 32 being arranged under a first high element 30 and each second low element 38 being arranged above a first low element 36.
  • the jack device 34 performs a first ascent so as to cause the first and second high elements 30 and 32 to interlock.
  • the barge 10 is lowered under the effect of the immersion control means accompanied simultaneously by a second ascent of the jack device 32 so as to maintaining the attachment of the first and second high elements 30 and 32 at the same time as the second lower elements 38 move towards the first lower elements 36 so as to cause them to interlock as shown in FIGS. figure 5 and 10 .
  • the barges 10 and platforms 14 are securely locked to one another with their respective compartments 16, 22 arranged facing each other.
  • an upper end 40 of the float 12 is arranged in contact with an upper face 42 of the compartment 18.
  • the lower end 44 of the float 12 is arranged with a set clearance "J" above a bottom 46 of the compartment 18.
  • the means for controlling the immersion level of the barge 10 are provided simply by the jack device 34.
  • the jack device 34 is dimensioned so as to be able to move the barge 10 relative to the platform 14 by opposing the buoyancy force acting on the barge 10, as shown in FIG. Figures 4 and 5 .
  • This configuration makes it possible in a simple manner to control the level of immersion.
  • the means for controlling the immersion level of the barge structure 10 could comprise at least one ballast immersion device of the barge 10.
  • the jack device 34 could be dimensioned downwards only to cause the hooking of the first and second high elements 30 and 32 and to accompany the barge 10 as it descends under the effect of the ballast immersion device (not shown), without having to oppose the Archimedean thrust.
