Medium-voltage (MV) submarine cable linking the Dutch mainland at Harlingen (Friesland) to the island of Vlieland in the Wadden Sea. The connection was realised by the electrical utility NUON; TKF (in partnership with CCC Netherlands) developed, produced and installed the submarine MV cable.

2006Commercial Operations Full Power
In 2006, the utility company Nuon realised a new 38 km long 20 kV submarine cable connection between Harlingen on the Dutch mainland and the island of Vlieland, laid on the Wadden Sea seabed by Visser & Smit Hanab, thereby connecting Vlieland to the Dutch national power grid and placing the cable into full operational service as the island’s grid supply link.
2006Onss Commissioned
As part of the Harlingen–Vlieland submarine cable project realised in 2006, a new substation was built in Harlingen near the monument ‘De Stenen Man’ and connected to the 20 kV cable, while on Vlieland the cable was connected to a local substation that now distributes electricity from the Dutch national grid across the island, replacing its previous reliance on local generators.
Date TBDCable Route Engineering
For the 38km, 20kV submarine cable between Harlingen and Vlieland, engineers completed detailed cable route and burial design through the Wadden Sea, taking into account stakeholder preferences, strong local currents that can shift cables, and risks from ship anchors. To mitigate these constraints they selected a specific trajectory, increased burial depth from the usual 2m to 3m, specified 10cm-thick insulated cable instead of laying a second emergency cable, and added a signal wire to enable rapid fault location in emergencies.
Date TBDCable Landfall Complete
As part of the Harlingen–Vlieland 20 kV submarine cable project, two shore landing points were constructed using horizontal directional drilling to bring the cable ashore at Harlingen and on Vlieland. At the mainland end the cable was connected to a new substation near the monument ‘De Stenen Man’, while on the island it was connected to a substation that distributes electricity across Vlieland.
