Offshore Wind turbines Marking: ICAO ANNEX-14

Published on Tuesday, 19 April of 2022

ICAO has created an annex for the correct marking of wind turbines to help aircraft. There are two main types of obstruction lights for aircrafts:


The obstacle lights should be installed on the nacelle to provide an unobstructed view for aircraft approaching from any direction. Depending on the height of the nacelle it will have one configuration or another.


On the other hand, the number of lanterns per section depends on the diameter of the structure at the top.

MSM has the equipment necessary for marking correctly all the offshore structures. MSM guarantees quality and durability in all its equipment. All AtoN equipment are available in our WINDFARM section.
