  • This vertical position is for example comprised between 0.5 m and 5 m above the floor 12 .
  • the immobilization of the fixed element 86 relatively to the deployable element 88 is for example ensured by welding, screwing or riveting or by plastic deformation.
  • the presence of the adjustment member 72 on the different legs 52 allows adjustment of the height of each adjustment member 72 which protrudes under the casing 70 between the lower wall 80 and the engaging member 74 , depending on the depth of the floor 12 facing the leg 52 .

  • the sleeve 112 further delimits a vertical slot 118 for receiving the indexation rib 46 , the slot 118 opening out upwards through a divergent cavity 120 for guiding the groove 46 towards the slot 118 .
  • the lower region 114 delimits a cylindrical central cavity with a substantially conjugate transverse section to the cross-section of the lower portion 44 .

  • the divergent cavity 120 is made in the upper region 116 at the upper end of the slot 118 .
  • the rib 46 is angularly immobilized in the slot 118 ensuring angular indexation of the hydrokinetic turbine 22 in a determined position around the axis C-C′.
  • This method is applied by means of a laying ship 130 provided with hoists 132 , such as cranes.
  • the hoists 132 have deployable lines 133 capable of moving the device 10 down into the body of water 14 .

  • the adjustment members 72 are then deployed at the surface for each leg 52 , by adjusting their height according to the calculated height values for each leg 52 .
  • the lower tubular elements 88 are immobilized at the determined height on the upper tubular elements 86 by welding or by plastic deformation at the surface of the body of water, for example on the laying ship 130 .
  • Actuation lines 133 are then attached on the attachment members 76 and the cranes 132 are maneuvered in order to extract the supporting foundation 20 from out of the ship 130 and place it facing the laying region 134 above or partly immersed in the body of water 14 .
  • a selected amount of solid and/or liquid ballast is then introduced into the inner space 78 of each casing 70 and the supporting foundation 20 is moved down into the body of water 14 .
  • the hydrokinetic turbine 22 is mounted beforehand on its support 54 by introducing the attachment stud 26 into the nacelle 110 as described earlier.
