Masdar acquired 35% (half of Statoil's 70% holding). Announced at UN Climate Summit, Sep 2014. The GBP 525m headline figure described as "investment" — includes equity + project funding commitment, not separable. Statoil and Statkraft had acquired 100% from Warwick Energy in Oct 2012 (70/30 split). FID taken Mar 2015. Ownership after: Statoil 35%, Masdar 35%, Statkraft 30%.

Statkraft's complete exit from offshore wind. GBP 555m for 30% of operational Dudgeon. Fully commissioned Oct 2017 (67x Siemens 6MW). Statkraft booked gain of NOK 5,106m. High implied EUR/MW reflects ROC subsidy regime (1.8 ROCs/MWh) which provides higher effective revenue than CfD. Originally reported GBP 555m, converted at GBP/EUR ~1.14 (2017). Ownership after: Equinor 35%, Masdar 35%, China Resources 30%.

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 the structures standing in the sea from satellite radar images (≈) and reads the count against the turbines and platforms on record. The farm was built before this count began, so the images show it complete; they cannot date its construction. Rows marked with a dot (·) come from Hafrok’s own registers.
