The lighting and marking specifications for North Hoyle Offshore Wind Farm were provided by Trinity House Lighthouse Service and the Civil Aviation Authority. The turbines are marked in accordance with these requirements, as follows:

• Each structure is painted yellow to 10m above H.A.T. (highest astronomical tide)
• The four corners of the wind farm
  • flashing yellow lights, 2.5 seconds, 5 nautical mile range, at a height of 10 metres above H.A.T.
  • fog signal Morse (U) 30 seconds
  • radar reflectors
  • red aviation navigation lights, on turbine nacelle
• The turbines in the middle of all sides of the wind farm
  • flashing yellow lights, 5 seconds, 2 nautical mile range, at a height of 10 metres above H.A.T.

In addition to these measures, all turbines are individually numbered at the base of the tower and on top of the nacelle. The chart below illustrates the lighting and marking arrangements. Please note that this should not be used for navigation and is provided for information only.
