Menck pile-driving solution selected for Hollandse Kust Zuid 1-4

Menck’s scope of work includes the manufacture, preparation and operation of one of its MHU 3500S hammers, which will be capable of installing monopiles with a 7.5-m outer diameter.

The offshore windfarm is to be equipped with Siemens Gamesa’s latest 11-MW wind turbine generators. The offshore operations phase is expected to take eight months and will be split into two installation campaigns.

Vattenfall took a final investment decision for the Hollandse Kust Zuid 1-4 offshore windfarm in mid-2020. With an installed capacity of 1.5 GW, Hollandse Kust Zuid is due to be fully operational in 2023.

Vattenfall was awarded permits to construct Hollandse Kust Zuid after winning two subsidy-free tender rounds in 2018 and 2019. The projects have been combined into one windfarm to optimise the construction process.

When it is fully operational in 2023, Hollandse Kust Zuid will provide around a third of the total installed offshore wind capacity in the Netherlands.
