Subsea 7 has been awarded a contract worth between $150 – $300 million by Vattenfall for the Hollandse Kust Zuid (HKZ) 1-4 offshore wind farm project.

Approximately 140 wind turbine monopile foundations and 315km of 66kV inner array grid cables will be installed in water depths between 18 and 27 meters.

Installation is scheduled for 2021 and 2022 using Seaway 7’s heavy lift, cable lay and support vessels.

When completed, the HKZ 1-4 offshore wind farms will have an installed capacity of approximately 1.5GW, which will meet the needs of around 2-3 million Dutch households.

“We look forward to working collaboratively with Vattenfall as a trusted partner to install the foundations and inner array cables for the Hollandse Kust Zuid 1-4 wind farms and help to deliver the first subsidy-free offshore wind project in the Netherlands.”
Steph McNeill, EVP Subsea 7.

“We look forward to working with Subsea7 on this exciting project. The Netherlands is an important market for us and we are very happy to contribute to making the Dutch energy system more sustainable and support our customers, large and small, on their way to fossil free living.”
Catrin Jung, head of offshore wind, Vattenfall.
