- the housing 160 also opens upwards into the upper surface of the mesh 152.
- the reference structure 42 is located on the mooring structure 40.
- the mesh 152 delimits at least two vertical pillars 162 located on either side of the housing 160 on which the rigid disconnectable articulated links 48 are mounted.
- a variant has the vertical pillars on one side of the intermediate removable floating unit 46 only, as in plant 10.
- each bar 102 forming a link 48 is fixed by being hinged on a pillar 162 and the second end 106 of the bar 102 is fixed on one side of the floating pontoon 80 of the intermediate floating unit 46.
- the movement of the intermediate floating unit 46 is independent of the movement of the floating transport structure 14 and that of the trellis 152.
- the operation of the fifth installation 150 is otherwise similar to that of the first installation 10 except that the floating transport structure 14 is moored on the trellis 152 using the attachment assembly 158.
