Second picture shows the intakes for the generators there, each intake per generator.
There are six generators on the ship, but with three in the forward amidships and three in the stern amidships area.
(showing three forward amidships generators and four prime mover GTs)
(showing everything -- the three stern amidships generators partially obscured by the logo, but still visible)
I don't think the number of these intakes would correspond to one generator each -- as there should only be three generators in that position (forward amidships), and for those intakes to go all the way to the stern amidships area would waste a lot of space.
Also, let's recall that there are additional side intakes as well on each side of the base of the structure.
