Since 1st May 2018, the following 3 offshore wind farms off the Dutch coast are free for passage and use: Princess Amalia Windpark (PAWP) near IJmuiden, Luchterduinen (LUD) near Noordwijk aan Zee and the Offshore Wind park near Egmond aan Zee (OWEZ).

It is smart to observe those rules since whoever does not will risk to face substantial penalties. Get the English translation of that Code of Conduct here – PDF download, 1.6 MB, 6 pages.
