Major Maintenance

In October 2021, Eneco commissioned Jan De Nul to carry out a major maintenance campaign on the Luchterduinen export cable, reburying the nearshore section to restore adequate depth of cover after morphological seabed changes had reduced burial depth. Using its modified intertidal trencher Sunfish, Jan De Nul reburied the live 150 kV export cable from the offshore high-voltage station towards the Noordwijk landfall to a minimum of 2.5 metres below the seabed, working up to 1 kilometre offshore in water depths of around 8.5 metres, ensuring continued protection of the operational transmission link without shutting down the wind farm.
