Country name United Kingdom correct
Region England, East of England correct
Comments Select for consent over Docking Shoal in part because the project is predicted to kill annually far fewer breeding Sandwich terns from the North Norfolk Coast SPA per turbine (0.31) than Docking Shoal (0.84). The Dudgeon mortality rate cannot exceed 28 Sandwich terns per year.

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 4-5 years Statoil may consider switching to fast 45 knot+ vessels.
