Region England, East of England correct
Comments Project will initially use a Service Operations Vessel (SOV) for O&M which will be in the field for a month at a time, with technicians working two weeks on and two off. The SOV will be needed in 2016, possibly earlier if used in construction. After four to five years Statoil will switch to a single fast 45 knot vessel.

Dudgeon will be part of Ofgem's Tender Round 5, expected to launch later in 2016, with regards to the sale of its offshore transmission assets once constructed.

Rune Rønvik stated at Offshore Wind Week 2016 that the project is on track to enforce 40% UK content.
