Seaway 7 has landed a large contract from Swedish energy company Vattenfall for the construction of the first subsidy-free Dutch offshore wind farm, Hollandse Kust Zuid 1 & 2. If the Dutch government also awards Vattenfall the concessions for Hollandse Kust Zuid 3 & 4, then Seaway 7 will build those as well.

Seaway 7’s envisaged scope of work includes the transport and installation of 76 monopile foundations and the laying of the inter-array cables and will be led from Seaway 7’s main office in the Netherlands.

The HKZ 1 & 2 wind farm is being developed by Vattenfall as the first subsidy-free wind farm in the
The Netherlands and is located approximately 30 km from the coast in the North Sea. Once fully
operational, HKZ 1 & 2 will be capable of supplying 760 MW which will be enough to meet the electricity
needs of one to one and half million households.

If Vattenfall also wins the ongoing tender for Hollandse Kust Zuid 3 & 4, then Seaway 7 will build those wind farms as well. This would add another 76 monopiles and associated array cables to the scope of work.

The offshore installation activities for all four wind farms are planned to be executed in 2022 using Seaway 7’s heavy lift and cable lay vessels, subject to the award of HKZ 3 & 4 to Vattenfall and pending Vattenfall’s final investment decision, says Seaway 7.
