From Hafrok’s transactions record
Dashed tick marks today (9 Sep 2026). The teal diamond on the spine is origination — the seabed award or round that created the project. Every other ownership event lives in the band below: one station per recorded deal, dated at its label, in deal order rather than to calendar scale. Secondary trades appear only at the interchanges; grey lines are parties whose entry or exit Hafrok’s record does not hold.

Hafrok counts foundations and turbines from satellite radar images (≈): a structure is counted once it is seen standing in the sea, which is not the same as producing power. A structure first seen in the last 60 days is not yet confirmed, because on a single image a freshly set foundation and a ship holding position look alike. Substation platforms are left out so the counts compare with the number of turbines. Rows marked with a dot (·) come from Hafrok’s own registers; a supplier or contract appears only where a source states it — everything else reads “not recorded”, never guessed.
Structures standing over time · count
strong line = confirmed · light line = seen in the last 60 days, not yet confirmed · the chart counts every structure (90 turbines + 2 platforms); the table counts turbines only
