[2] Maximum distance measured from rotors of one wind turbine to the rotors of another wind turbine.

[3] Mooring line radius is the horizontal distance from the top connector at the floating foundation to a point in line with the bottom connector at the seabed anchor.

[4] Anchoring Option 2 (DEAs only) does not require scour protection, therefore, this option has been omitted from this table.

[5] Based upon findings of the Ordtek (2022) desk-based study. This value is based upon German World War II ground mines; these have not been recorded as having been present within the vicinity of the Array, however, there is a background risk from unrecorded mine lays. The likelihood of encountering a UXO of this type and charge weight is considered very unlikely as these types of mines typically targeted ports and shallower waters than are recorded within the Array (Ordtek, 2022).

[6] Based upon findings of the Ordtek (2022) desk-based study. This value is based upon British World War II mines; a total of nine British World War II minefields are recorded as having been present within the vicinity of the Array, the closest of which was recorded as being located 23 km north of the Array. Although mine sweeping operations were undertaken within the vicinity, there is potential for migration and subsequent burial of UXO from their original lay position, therefore, there is potential that these may be encountered within the Array although this is considered unlikely (Ordtek, 2022).
