# The Norfolk Boreas Offshore Wind Farm Order 2021, Paragraph 2: Detailed offshore design parameters

Extent: E+W

Subject to paragraph (2), any wind turbine generator forming part of the authorised project must not—
(a) exceed a height of 350 metres when measured from HAT to the tip of the vertical blade;
(b) exceed a height of 198.5 metres to the height of the centreline of the generator shaft forming part of the hub when measured from HAT;
(c) exceed a rotor diameter of 303 metres;
(d) be less than 800 metres from the nearest wind turbine generator in either direction perpendicular to the approximate prevailing wind direction (crosswind) or be less than 800 metres from the nearest wind turbine generator in either direction which is in line with the approximate prevailing wind direction (downwind); or
(e) have a draught height which is less than the minimum draught height specified for the relevant wind turbine generator capacity in the table below—
Wind Turbine Generator Capacity
Minimum draught height
Up to and including 14.6MW
