Boskalis did not disclose the contract’s exact value, stating only that it falls between $56.7m (€50m) and €150m.
Located approximately 45 nautical miles north-west of IJmuiden, the Zeevonk Offshore Wind Farm is one of the largest renewable energy developments in the Netherlands and is being built in two phases of roughly 1GW each.
The contract covers phase one, which is expected to begin commercial operation in 2029.
Boskalis’ scope includes transporting and installing around 149km of 66kV inter-array cables, which will connect 69 wind turbines across the offshore site.
The company will also test and terminate the cables and install cable protection systems.
The cable is expected to be transported from a facility in Eemshaven, the Netherlands, before installation at sea using the BOKA Ocean cable-laying vessel.
Boskalis will also undertake survey work and seabed intervention, deploying one of its subsea rock installation vessels for these tasks.
Engineering work is expected to begin in the near term, while the offshore installation campaign is currently scheduled for 2029.
Phase one of the Zeevonk Offshore Wind Farm is set to contribute significantly to renewable energy production in the region.
The project aligns with the company’s broader strategic focus on markets driven by rising energy consumption and the global shift towards renewable power generation.
In May 2026, Boskalis announced an investment in a new 24,000t cable-laying vessel to address growing demand in the offshore wind and interconnector sectors.
