Subsea 7 business unit Seaway 7 has been selected by Vattenfall as one of its partners for the Hollandse Kust Zuid 1 & 2 offshore windfarm and could also play a major role on the upcoming Hollandse Kust Zuid 3 & 4 project.
Seaway 7's envisaged scope of work includes transporting and installing 76 monopile foundations and laying the inter-array cables. The project will be led from Seaway 7’s main office in the Netherlands.
The Hollandse Kust Zuid 1 & 2 windfarm is being developed by Vattenfall as the first subsidy-free windfarm in the Netherlands. It is located approximately 30 km from the Dutch coast in the North Sea.
Once fully operational, Hollandse Kust Zuid 1 & 2 will be a 760-MW project.
In addition, Seaway 7 has been chosen as one of Vattenfall's partners for the ongoing tender for the Hollandse Kust Zuid 3 & 4 offshore windfarm.
This would add 76 monopiles and associated array cables to the programme of work, if the development is awarded to Vattenfall by the Dutch Government.
The integrated offshore installation activities for Hollandse Kust Zuid 1 & 2 and Hollandse Kust Zuid 3 & 4 will 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.
