Swedish power company Vattenfall has tapped Seaway 7 for installation work at the Hollandse Kust Zuid (HKZ) 1 & 2 offshore wind farm development offshore the Netherlands.

Seaway 7, a subsidiary of Subsea 7, will perform a work scope including transport and installation of 76 monopile foundations and the laying of the inter-array cables, all 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 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 approximately 1 million - 1.5 million households.

In addition, Seaway 7 has been chosen as one of Vattenfall’s partners for the ongoing tender for the HKZ 3 & 4 offshore wind farm. This would add 76 monopiles and associated array cables to the program of work, if this development is awarded to Vattenfall by the Dutch Government.

The integrated offshore installation activities for both the HKZ 1 & 2 and HKZ 3 & 4 wind farm projects 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.
